The '''weather''' (Japanese: '''{{tt|天気|てんき}}''' ''weather'') is a set of mechanics in the [[Pokémon games]] that change the battle environment, activating {{Abilities}}, modifying certain [[move]]s, and potentially damaging the {{OBP|Pokémon|species}} in battle or affecting their [[stats]]. They have been included in every [[core series]] game since [[Generation II]]. Only one type of weather may be present at a time; an effect that creates weather will remove the previous weather.
The '''weather''' (Japanese: '''{{tt|天気|てんき}}''' ''weather'') is a set of mechanics in the [[Pokémon games]].


In Generation II, the only way to cause weather was by a Pokémon using a [[move]] in-battle. [[Generation III]] introduced [[:Category:Abilities with effects on weather conditions|weather-related Abilities]] as well as overworld weather; starting a battle in an overworld location with weather would cause that weather to be automatically present from the beginning of the battle. [[Generation IV]] introduced four held items ([[Heat Rock|Heat]], [[Damp Rock|Damp]], [[Smooth Rock|Smooth]], and [[Icy Rock]]s) that increase the duration of weather caused by {{cat|weather-changing moves}} or [[Ability|Abilities]]. [[Generation V]] introduced [[Season (mechanic)|seasons]], which may affect the weather in certain locations, and [[Generation VI]] introduced a new [[evolution]] method affected by the weather. [[Generation VIII]] introduced overworld effects that resemble weather but do not directly correspond with an in-battle weather.

In the [[core series]], the weather changes the battle environment, activating {{Abilities}}, modifying certain [[move]]s, and potentially damaging the {{OBP|Pokémon|species}} in battle or affecting their [[stats]].

==Types of weather and effects==
In Generation II, the only way to cause weather was by a Pokémon using a [[move]] in-battle. [[Generation III]] introduced [[:Category:Abilities with effects on weather conditions|weather-related Abilities]] as well as overworld weather; starting a battle in an overworld location with weather would cause that weather to be automatically present from the beginning of the battle. [[Generation IV]] introduced four held items ([[Heat Rock|Heat]], [[Damp Rock|Damp]], [[Smooth Rock|Smooth]], and [[Icy Rock]]s) that increase the duration of weather caused by {{cat|weather-changing moves}} or [[Ability|Abilities]]. [[Generation V]] introduced {{season}}s, which may affect the weather in certain locations, and [[Generation VI]] introduced a new [[evolution]] method affected by the weather. [[Generation VIII]] introduced overworld effects that resemble weather but do not directly correspond with an in-battle weather.
===Overview===
*'''Clear skies''': The absence of weather. This is the weather found in most locations.
*'''[[Harsh sunlight]]''': Strong sunlight shines on the battlefield. It is one of the rarest conditions to be seen in the overworld.
**'''[[Harsh sunlight|Extremely harsh sunlight]]''': Sunlight shines more heavily on the battlefield. This has only occurred in the overworld in the [[Hoenn]] region, in [[Pokémon Omega Ruby and Alpha Sapphire|Pokémon Omega Ruby]], due to {{p|Groudon}}'s emergence.
*'''[[Rain]]''': Rain falls on the battlefield. Different variations of this weather may appear on the overworld. This is the most common weather pattern that may be found on [[route]]s and occasionally in cities.
**'''[[Rain|Heavy rain]]''': Rain falls more chaotically around the battlefield. This has only occurred in the overworld in the [[Hoenn]] region, in [[Pokémon Omega Ruby and Alpha Sapphire|Pokémon Alpha Sapphire]], due to {{p|Kyogre}}'s emergence.
*'''{{weather|Sandstorm}}''': Stinging sand whips across the battlefield. In Generations III through V, every new [[region]] had a specific area where a sandstorm was always occurring.
*'''{{weather|Hail}}''': Pelting hail falls on the battlefield. On the overworld, this may appear as a blizzard, hailstorm, or snowfall.
**'''[[Snow]]''': A snowstorm occurs on the battlefield. This weather condition replaces hail in [[Generation IX]].
*'''{{weather|Shadowy aura}}''': Bursts of light rain down from a shadowy aura in the sky. This type of weather is only present in [[Pokémon XD: Gale of Darkness]] and has no overworld manifestation anywhere.
*'''[[Fog]]'''{{sup/4|DPPt}}: A thick fog clouds the battlefield.
*'''[[Strong winds]]''': A strong air current blows across the battlefield. This weather can only be present in battle as a result of {{a|Delta Stream}}, {{me|Rayquaza}}'s [[signature Ability]].


The following overworld effects resemble weather, but do not directly match the in-battle mechanic:
===Pokémon battles===
*'''Fog'''{{sup/8|SwShBDSP}}: Causes {{m|Misty Terrain}} in battle instead of a weather.
====List of weather====
*'''Thunderstorm''': Simultaneously causes rain and {{m|Electric Terrain}}.
The following lists all the weather conditions in {{pkmn|battle}}s. Note that in {{g|Legends: Arceus}}, weather conditions do not behave the same way they do in the other games.
*'''{{weather|Diamond dust}}''': A special, purely aesthetic version of light snow. It first appeared as an [[Easter egg]] in {{game|Diamond and Pearl|s}}, and has appeared in several [[core series]] games since.
*Areas may also have light snow, foggy, or cloudy overworld effects that are aesthetic and do not cause any weather mechanic in battle.


In [[Generation V]], the weather was given an icon which appeared on the DS or 3DS's bottom screen in a battle whenever weather was occurring. Since fog and shadowy aura do not appear in-battle in Generation V, they have no icons. When there is no weather, no icon is shown.

In {{g|Sword and Shield}}, overworld weather effects mostly occur in the [[Wild Area]], [[Isle of Armor]], and [[Crown Tundra]], including those that do not directly correspond to the in-battle weather mechanic.

====Moves affected by weather====
Certain specific moves are also affected in special ways by the weather.
*The recovery moves {{m|Synthesis}}, {{m|Morning Sun}}, and {{m|Moonlight}} restore more HP than usual in harsh sunlight, and less than usual in most other weather.
**In Generation II, during no weather they normally restore ¼ total HP, during [[harsh sunlight]] they normally restore ½ total HP, and during other weather they normally restore ⅛ total HP. Except in link battles, the amount of HP restored is doubled if it is the move's preferred time of day (morning for Morning Sun, day for Synthesis, night for Moonlight).
**From Generation III onward, during no weather or [[strong winds]] they restore ½ total HP, during [[harsh sunlight]] they restore ⅔ total HP, and during other weather they restore ¼ total HP.
*The move {{m|Shore Up}} restores ⅔ of the user's total HP during a sandstorm; outside of a sandstorm, it only restores ½ total HP.
*The accuracy of {{m|Thunder}}, {{m|Hurricane}}, {{m|Blizzard}}, {{m|Bleakwind Storm}}, {{m|Wildbolt Storm}}, and {{m|Sandsear Storm}} are affected by the weather.
**From [[Generation IV]] onward, during hail Blizzard ignores accuracy and evasion checks.
**During rain, Thunder and Hurricane ignore accuracy and evasion checks; during harsh sunlight, Thunder and Hurricane only have 50% accuracy.
**In Generation IX, during rain, Bleakwind Storm, Wildbolt Storm, and Sandsear Storm ignore accuracy and evasion checks.
**In {{game|Diamond and Pearl|s}} only, Blizzard and Thunder also have a 30% chance to hit through {{m|Protect}} or {{m|Detect}} when used in hail or rain, respectively.
*{{m|Solar Beam}} and {{m|Solar Blade}} become one-turn moves in harsh sunlight, skipping their charge turn; in rain, sandstorm, hail, and fog, the moves' powers are halved.
*From Generation V onward, during harsh sunlight {{m|Growth}} increases the user's {{stat|Attack}} and {{stat|Special Attack}} by two stages each instead of one.
*In Generations IV and V, and {{g|X and Y}}, when used as a [[field move]] {{m|Sweet Scent}} fails if there is a non-aesthetic weather effect in the area.
*The move {{m|Aurora Veil}} can only be used successfully during hail or snow; otherwise it fails.
 
====Activated Abilities====
The following Abilities are activated when a type of weather comes into effect. Most of these Abilities have no effect if no weather is active.

In addition to the above Abilities, {{a|Harvest}} is guaranteed to restore a Berry whenever it triggers in harsh sunlight, and the Abilities {{a|Overcoat}} and {{a|Magic Guard}} will prevent weather-related damage.
 
====Castform and Weather Ball====
{{main|Castform (Pokémon)}}
{{main|Weather Ball (move)}}
{{p|Castform}} is a Pokémon uniquely designed to take advantage of the weather. Its [[Ability]], {{a|Forecast}}, causes it to change [[List of Pokémon with form differences#Castform|form]] when a type of weather is present. Forecast does not cause a unique change for every possible type of weather, though.

{{m|Weather Ball}} is a [[move]] that uniquely takes advantage of the weather. In [[Generation III]], it was introduced along with Castform and was Castform's [[signature move]].
 
Whenever there is a type of weather present, Weather Ball's base power will double to 100. Weather Ball's type also changes during most types of weather.

===Causing weather===
Because of its Ability, Castform has a unique synergy with Weather Ball that no other Pokémon that can learn Weather Ball has. In harsh sunlight, rain, or hail, Castform will always get [[Same-type attack bonus|STAB]] thanks to its Ability.
 
====Causing weather====
Most of the types of weather have a [[move]] or [[Ability]] that will cause that weather.

Weather normally lasts for 5 turns when it is called by a move. Prior to [[Generation VI]], weather created by an Ability would continue until the battle ended or another type of weather took its place; since Generation VI, weather created by Abilities also lasts for only 5 turns, with the exception of weather created by {{a|Desolate Land}}, {{a|Primordial Sea}}, and {{a|Delta Stream}}.

As of [[Generation IX]], moves and Abilities that change the weather will fail if a weather condition is occurring in the overworld.


If multiple Pokémon with Abilities that change the weather are sent in simultaneously, the Abilities activate in order from [[Statistic|fastest]] Pokémon to slowest Pokémon (or the reverse during {{m|Trick Room}}); this means that the slowest Pokémon's Ability will override the other Abilities.

When there is weather in the overworld, that weather will appear in every battle and last until it is replaced by another weather (fog and Terrains can also be cleared by {{m|Defog}}). In addition, Defog may clear fog from an overworld area (in [[Sinnoh]] only). It is the only move that has any effect on weather in the overworld.


In [[Generation V]], it is possible to temporarily remove overworld weather by saving the game, setting the DS's [[time|clock]] to one month later (to change the season), loading the save file, and [[caught Pokémon|catching]] a Pokémon without leaving the area. This works even if the area always has the same weather regardless of the season.
====Visual indicators====
=====Generation V=====
In [[Generation V]], the weather was given an icon which appeared on the DS or 3DS's bottom screen in a battle whenever weather was occurring. Since fog and shadowy aura do not appear in-battle in Generation V, they have no icons. When there is no weather, no icon is shown.

===Effects===
=====Generation VI=====
Three of the types of weather can do damage to Pokémon in battle at the end of a turn. In a {{weather|sandstorm}}, {{weather|hail}}, or {{weather|shadowy aura}}, any Pokémon that is not {{t|Rock}}-, {{t|Ground}}-, or {{type|Steel}}; {{type|Ice}}; or a [[Shadow Pokémon]] (respectively) will be damaged for <sup>1</sup>/<sub>16</sub> of its maximum HP. Certain {{Abilities}} prevent damage from weather effects, though, and a Pokémon holding [[Safety Goggles]] is also immune to damage from weather effects.
In [[Generation VI]] onwards, the background of the bottom screen shows an animation of the current weather.


Sandstorm, [[fog]], and [[snow]] all affect the [[stats]] of Pokémon on the battlefield. Since Generation IV, in a sandstorm, the {{stat|Special Defense}} of {{type|Rock}} Pokémon is increased by 50%. In fog, the accuracy of all Pokémon in battle is decreased. Snow increases the {{stat|Defense}} of {{type|Ice}} Pokémon by 50%.
=====Generation VII=====
In [[Pokémon Sun and Moon|Pokémon Sun, Moon]], [[Pokémon Ultra Sun and Ultra Moon|Ultra Sun, and Ultra Moon]], the 3DS's bottom screen displays an icon and background animation of the current weather.


During [[harsh sunlight]], no Pokémon can be {{status|freeze|frozen}}.
{{Incomplete|section|Generation VI screenshots}}
 
Harsh sunlight and [[rain]] both affect the power of certain types of [[move]]s. [[Harsh sunlight]] strengthens the power of {{type|Fire}} moves by 50% and weakens the power of {{type|Water}} moves by 50%, while [[rain]] does the opposite, strengthening Water-type moves by 50% while weakening Fire-type moves by 50%.
 
Certain specific moves are also affected in special ways by the weather.
*The recovery moves {{m|Synthesis}}, {{m|Morning Sun}}, and {{m|Moonlight}} restore more HP than usual in harsh sunlight, and less than usual in most other weather.
**In Generation II, during no weather they normally restore ¼ total HP, during [[harsh sunlight]] they normally restore ½ total HP, and during other weather they normally restore ⅛ total HP. Except in link battles, the amount of HP restored is doubled if it is the move's preferred time of day (morning for Morning Sun, day for Synthesis, night for Moonlight).
**From Generation III onward, during no weather or [[strong winds]] they restore ½ total HP, during [[harsh sunlight]] they restore ⅔ total HP, and during other weather they restore ¼ total HP.
*The move {{m|Shore Up}} restores ⅔ of the user's total HP during a sandstorm; outside of a sandstorm, it only restores ½ total HP.
*The accuracy of {{m|Thunder}}, {{m|Hurricane}}, and {{m|Blizzard}} is affected by the weather.
**From [[Generation IV]] onward, during hail Blizzard ignores accuracy and evasion checks.
**During rain, Thunder and Hurricane ignore accuracy and evasion checks; during harsh sunlight, Thunder and Hurricane only have 50% accuracy.
**In {{game|Diamond and Pearl|s}} only, Blizzard and Thunder also have a 30% chance to hit through {{m|Protect}} or {{m|Detect}} when used in hail or rain, respectively.
*{{m|Solar Beam}} and {{m|Solar Blade}} become one-turn moves in harsh sunlight, skipping their charge turn; in rain, sandstorm, hail, and fog, the moves' powers are halved.
*From Generation V onward, during harsh sunlight {{m|Growth}} increases the user's {{stat|Attack}} and {{stat|Special Attack}} by two stages each instead of one.
*In Generations IV and V, and {{g|X and Y}}, when used as a [[field move]] {{m|Sweet Scent}} fails if there is a non-aesthetic weather effect in the area.
*The move {{m|Aurora Veil}} can only be used successfully during hail; outside of hail, it fails.
 
===Activated Abilities===
The following Abilities are activated when a type of weather comes into effect. Most of these Abilities have no effect if no weather is active.

In addition to the above Abilities, {{a|Harvest}} is guaranteed to restore a Berry whenever it triggers in harsh sunlight, and the Abilities {{a|Overcoat}} and {{a|Magic Guard}} will prevent weather-related damage.
=====Generation VIII=====


===Castform and Weather Ball===
======Sword and Shield======
{{main|Castform (Pokémon)}}
In {{g|Sword and Shield}}, weather conditions can be seen in-battle by pressing '''Y''' for '''Info'''.
{{main|Weather Ball (move)}}
{{p|Castform}} is a Pokémon uniquely designed to take advantage of the weather. Its [[Ability]], {{a|Forecast}}, causes it to change [[List of Pokémon with form differences#Castform|form]] when a type of weather is present. Forecast does not cause a unique change for every possible type of weather, though.

{{m|Weather Ball}} is a [[move]] that uniquely takes advantage of the weather. In [[Generation III]], it was introduced along with Castform and was Castform's [[signature move]].
======Legends: Arceus======
In {{g|Legends: Arceus}}, weather conditions can be seen in-battle by pressing '''+''' to open the "Status Info" view, noted at the bottom of the view.  
 
{| style="margin:auto; text-align:center; {{roundy|20px}} border: 2px solid #{{Hisui color dark}}; background: #{{Hisui color}}; font-size:80%; padding:4px; padding-bottom:0px; color:#fff"

Whenever there is a type of weather present, Weather Ball's base power will double to 100. Weather Ball's type also changes during most types of weather.
=====Generation IX=====
In {{g|Scarlet and Violet}}, weather conditions can be seen in-battle by pressing '''Y''' for '''Check Status''', listed under "Active Battle States and Effects". Weather conditions caused by the overworld will not display a duration, and they may appear or disappear without notice as the overworld weather changes.

Because of its Ability, Castform has a unique synergy with Weather Ball that no other Pokémon that can learn Weather Ball has. In harsh sunlight, rain, or hail, Castform will always get [[Same-type attack bonus|STAB]] thanks to its Ability.
===Overworld===
{{incomplete|section}}
Overworld weather varies between games. There are a larger variety of overworld weather conditions compared to a battle, however some conditions do not affect battles. If a weather condition is present in a [[Route]], sector of the [[Wild Area]] or location within [[Pokémon Legends: Arceus]] or {{g|Scarlet and Violet}}, the weather will appear in every battle and last until it is replaced by another weather, and returns to the original weather in the overworld. In addition, Defog may clear fog from an overworld area (in [[Sinnoh]] only).
 
{{DL|Easter Egg|Diamond Dust}} is a special, purely aesthetic version of light snow, and replaces hail where applicable, allowing the player to battle without the effects of hail, without changing the weather manually. It first appeared as an [[Easter egg]] in {{game|Diamond and Pearl|s}}, and has appeared in several [[core series]] games since.
 


===Weather-dependent evolution===
====Weather-dependent evolution====
Starting at level 50, {{p|Sliggoo}} (as well as its [[Regional form|Hisuian form]]) will evolve into {{p|Goodra}} if it is leveled up during [[rain]] or [[fog]] in the overworld.
Starting at level 50, {{p|Sliggoo}} (as well as its [[Hisuian form]]) will evolve into {{p|Goodra}} if it is leveled up during [[rain]] or [[fog]] in the overworld.

Line 335: Line 385:
|}
|}


==[[Pokémon Legends: Arceus]]==
====Johto====
* In {{game|HeartGold and SoulSilver|s}}, {{rt|33|Johto}} is always [[rain]]y.
** The [[Lake of Rage]] is also rainy on most [[days of the week]], but is clear on Wednesdays.
* The snow on the summit areas of [[Mt. Silver Cave]] will activate {{weather|Hail}} in battles.
 
====Hoenn====
In [[Hoenn]], several areas have weather conditions that occur naturally:
* [[Fog]] is present at the summit of [[Mt. Pyre]], but it has no effect in battles.
* There is always a sandstorm on [[Hoenn Route 111|Route 111]]
* It frequently rains on {{rt|119|Hoenn}}, with clear skies only on one in four days.
* It always rains on a section of {{rt|120|Hoenn}} between the two log bridges corresponding roughly where the [[Ancient Tomb]] is located.
* It rains on one in four days in {{rt|123|Hoenn}} - at the same time, the rain on Route 119 will be thundery.
 
Several weather conditions are also triggered by in-game events:
* When {{p|Kyogre}} is awakened, a rain/heavy rain is present. In contrast to natural rain, rain summoned by Kyogre includes thunderstorms as well as more rain.
* When {{p|Groudon}} is awakened, harsh sunlight/extremely harsh sunlight is present.
* {{game|Emerald}} involves both Groudon and Kyogre being awakened in that order. Groudon is awakened first but does not immediately change the weather; once Kyogre is awakened, the weather will alternate between rain and harsh sunlight.
 
The requisite visit to [[Seafloor Cavern]] to defeat [[Maxie]]{{sup/3|R}}{{sup/6|OR}}/[[Archie]]{{sup/3|S}}{{sup/3|E}}{{sup/6|AS}} will subsequently awaken Groudon/Kyogre and cause the respective weather condition to affect four cities: [[Lilycove City]], [[Mossdeep City]], [[Sootopolis City]] and [[Ever Grande City]], as well as their connecting routes east of Lilycove. In {{game|Emerald}}, after reaching the [[Sky Pillar]] during the crisis, its unique weather distortion will spread to the routes east of but not including [[Pacifidlog Town]] as well. While the weather condition is present, a different background music plays, overriding the usual city and route themes as well as the surfing and cycling themes.
 
====Sinnoh====
* A {{weather|sandstorm}} is present on {{rt|228|Sinnoh}} at all times.
* [[Fog]] obscures the player's overworld vision on the northern section of {{rt|210|Sinnoh}}, the basement floor of [[Mount Coronet]], the upper floors of the [[Lost Tower]], the postgame section of Sinnoh's {{si|Victory Road}}, and [[Turnback Cave]]. It can be removed using {{m|Defog}}.
** In {{g|Brilliant Diamond and Shining Pearl}}, fog activates {{m|Misty Terrain}} in battles.
 
====Unova====
In [[Unova]], {{season}}s play a significant role in what weather conditions can form in the overworld.
 
In [[Generation V]], it is possible to temporarily remove overworld weather by saving the game, setting the DS's [[time|clock]] to one month later (to change the season), loading the save file, and [[caught Pokémon|catching]] a Pokémon without leaving the area. This works even if the area always has the same weather regardless of the season.
 
====Kalos====
 
====Alola====
*A [[Sandstorm (weather condition)|Sandstorm]] will be present in [[Haina Desert]] between 5:00 PM and 9:59 AM. Otherwise, the weather will be [[Harsh sunlight|Harsh Sunlight]].
 
[[Rain]] will occur in several locations, and depends on certain conditions:
* In {{g|Sun and Moon}} [[Brooklet Hill]] will rain during [[Lana]]'s [[Island challenge|trial]], after catching or defeating the first [[Wishiwashi]], and before completing the trial.
** In {{g|Ultra Sun and Ultra Moon}}, it will instead rain between catching/defeating the second Wishiwashi and before completing the trial.
* [[Lush Jungle]], Brooklet Hill, [[Malie City]], [[Malie Garden]], Routes [[Alola Route 10|10]], [[Alola Route 11|11]], [[Alola Route 12|12]], [[Alola Route 13|13]], [[Blush Mountain]], and [[Secluded Shore]] will rain between 5:00 PM and 6:00 PM.
* [[Tapu Village]] and [[Alola Route 14|Route 14]] will rain on some days.
* [[Exeggutor Island]] will rain at certain times with two different intensities, light rain will occur between 10 AM - 3:59 PM, and strong rain will occur between 6 PM - 11:59 PM.
* [[Alola Route 17|Route 17]] will always rain.
====Galar====
In {{g|Sword and Shield}}, overworld weather effects mostly occur in the [[Wild Area]], [[Isle of Armor]], and [[Crown Tundra]], including those that do not directly correspond to the in-battle weather mechanic.

In Pokémon Legends: Arceus, weather is a mechanic that is completely controlled by the environment, and it is reset each day. Weather plays a role in the spawn distributions of wild Pokémon and also has certain in-battle effects. There are no [[move]]s that can affect the weather.

{{incomplete|section|needs=How much does Rainbow Light heal?}}
In {{g|Scarlet and Violet}}, the player can check the current weather from their map. Overworld weather changes much more frequently in this game.  
Various weather effects appear in certain dungeons in the [[Pokémon Mystery Dungeon series]]. Weather effects can change from floor to floor, and can also be altered through the use of [[Wonder Orb]]s. In [[Pokémon Mystery Dungeon: Gates to Infinity|Gates to Infinity]], Pokémon will regenerate HP only if the weather is Clear, or if it is holding a {{DL|Scarf (Mystery Dungeon)|Weather Band}}. In {{pkmn|Super Mystery Dungeon}} and [[Pokémon Mystery Dungeon: Rescue Team DX|Rescue Team DX]], Pokémon can regenerate HP in any weather as long as they do not take damage from the weather condition, or if it is holding a {{DL|Looplet|Weather Looplet}}.
 
[[Uproar Forest]], [[Howling Forest]], [[Lightning Field]], [[Mt. Faraway]], [[Northern Range]], [[Pitfall Valley]], [[Wyvern Hill]] and [[Purity Forest]] have random weather effect on specific floors.
 
The Abilities {{a|Cloud Nine}} and {{a|Air Lock}} cause the floor to have ineffective weather as long as there is at least one Pokémon on the floor with either of the aforementioned Abilities. Prior to Gates to Infinity, the Abilities change the weather on the floor to Clear and renders Wonder Orbs, moves, and other Abilities that change the weather useless.

===Pokémon GO===
[[File:GO Weather.png|thumb|right|200px|Weather status screen showing the current weather and effects on boosted types]]
Various weather effects appear in {{g|GO}}, intended to reflect the actual weather of the player's location. Weather in each local area is updated every hour, on the hour, via {{wp|Accuweather}}. Different weathers affect certain Pokémon types, and effects include:
* Increasing the power of moves of boosted types in {{OBP|Gym|GO}} and {{OBP|Raid Battle|GO}}s by 20% (rounded down to the nearest integer)
* Wild Pokémon with a weather-boosted type...
** spawn more frequently
** award 25% extra {{OBP|Stardust|GO}} when caught
** are guaranteed at least 4 {{IV}}s in each stat.
** are five [[Power Up]] levels higher than normal (capped at 35 instead of 30 for wild Pokémon, 25 instead of 20 for Raid Bosses, and 13 instead of 8 for {{OBP|Shadow Pokémon|GO}})
** have a swirling, white aura in the overview map
* The form of wild {{p|Castform}} depends on the weather
* The form of wild {{p|Cherrim}} depends on the weather
** Cherrim appear in Sunshine Form during sunny/clear weather and Overcast Form otherwise
* Prior to the introduction of seasons to Pokémon GO, some species only spawned under specific weather conditions (outside of certain [[List of events (GO)|in-game events]]):
** {{p|Cacnea}} and its evolutionary family exclusively spawned in sunny/clear weather
** {{p|Lotad}} and its evolutionary family exclusively spawned in rainy weather
 
Weather bonuses are not applied for Pokémon encounters from [[Field Research|Field]] or [[Special Research]] and [[GO Battle League]] rewards. Bonus damage is also not applied in {{OBP|Trainer Battle|GO}}s, including [[Team GO Rocket]] battles.
 
If a weather change causes an existing wild Pokémon spawn to gain (or lose) its weather boost, then its Power Up level will be raised (or lowered) by 5 and its IVs will be re-rolled. However, any weather-dependent forms will remain the same.

In [[Pokémon Mystery Dungeon: Gates to Infinity|Gates to Infinity]], Pokémon will regenerate HP only if the weather is Clear, or if it is holding a {{DL|Scarf (Mystery Dungeon)|Weather Band}}. In {{pkmn|Super Mystery Dungeon}} and [[Pokémon Mystery Dungeon: Rescue Team DX|Rescue Team DX]], Pokémon can regenerate HP in any weather as long as they do not take damage from the weather condition, or if it is holding a {{DL|Looplet|Weather Looplet}}.
===Pokémon GO===

Unlike with the main series games, Ice-type Pokémon are not immune to damage from hail; similarly, Rock-type, Steel-type, and Ground-type Pokémon are not immune to damage from sandstorm. Instead, the effects of hail and sandstorm are nullified by the [[passive skill]]s Snow Shelter and Sand Shelter, respectively.
Like in the main games, these weather conditions can be triggered with the respective moves ({{m|Sunny Day}}, {{m|Rain Dance}}, {{m|Hail}}, {{m|Sandstorm}}). As well, certain skills can activate weather conditions whether it is after using a sync move or upon entry.

The weather (Japanese: 天気 weather) is a set of mechanics in the Pokémon games.

In the core series games

In the core series, the weather changes the battle environment, activating Abilities, modifying certain moves, and potentially damaging the Pokémon in battle or affecting their stats. They have been included in every core series game since Generation II. Only one type of weather may be present at a time; an effect that creates weather will remove the previous weather.

In Generation II, the only way to cause weather was by a Pokémon using a move in-battle. Generation III introduced weather-related Abilities as well as overworld weather; starting a battle in an overworld location with weather would cause that weather to be automatically present from the beginning of the battle. Generation IV introduced four held items (Heat, Damp, Smooth, and Icy Rocks) that increase the duration of weather caused by weather-changing moves or Abilities. Generation V introduced seasons, which may affect the weather in certain locations, and Generation VI introduced a new evolution method affected by the weather. Generation VIII introduced overworld effects that resemble weather but do not directly correspond with an in-battle weather.

Pokémon battles

List of weather

The following lists all the weather conditions in battles. Note that in Pokémon Legends: Arceus, weather conditions do not behave the same way they do in the other games.

Weather Image In-game description Details
Harsh sunlight The harsh sunlight weather condition. It boosts the power of Fire-type moves and lowers the power of Water-type moves. Harsh sunlight strengthens the power of Fire-type moves by 50% and weakens the power of Water-type moves by 50%. During harsh sunlight, no Pokémon can be frozen.

In Pokémon Legends: Arceus, it instead increases the Speed of Grass-type Pokémon and activates Cherrim's Sunshine Form.

Rain

The rain weather condition. It boosts the power of Water-type moves and lowers the power of Fire-type moves.

Rain strengthens Water-type moves by 50% while weakening Fire-type moves by 50%.
Sandstorm The sandstorm weather condition. At the end of each turn, it damages all Pokémon that are not Rock, Ground, or Steel types. It boosts the Sp. Def of Rock-type Pokémon. Any Pokémon that is not Rock-, Ground-, or Steel-type will be damaged for 1/16 of its maximum HP at the end of each turn. Certain Abilities prevent damage from weather effects, though, and a Pokémon holding Safety Goggles is also immune to damage from weather effects.

Since Generation IV, in a sandstorm, the Special Defense of Rock-type Pokémon is increased by 50%.

Hail The hail weather condition. At the end of each turn, it damages all Pokémon that are not Ice types. Any Pokémon that is not Ice-type will be damaged for 1/16 of its maximum HP at the end of each turn. Certain Abilities prevent damage from weather effects, though, and a Pokémon holding Safety Goggles is also immune to damage from weather effects. This weather was replaced by Snow in Generation IX.
Snow

The snow weather condition. It makes Blizzard more likely to hit and boosts the Defense of Ice-type Pokémon.

Snow increases the Defense of Ice-type Pokémon by 50%. This weather condition replaces Hail in Generation IX.
Fog N/A This weather condition only exists in Sinnoh and Hisui. A thick fog clouds the overworld and battlefield, reducing the accuracy of all moves.
Extremely harsh sunlight The extremely harsh sunlight weather condition. It boosts the power of Fire-type moves and protects Pokémon from Water-type moves. Sunlight shines more heavily on the battlefield. This has only occurred in the overworld in the Hoenn region, in Pokémon Omega Ruby, due to Groudon's emergence.
Heavy rain The heavy rain weather condition. It boosts the power of Water-type moves and protects Pokémon from Fire-type moves. Rain falls more chaotically around the battlefield.
Strong winds The strong winds weather condition. The power of moves that are super effective against Flying-type Pokémon is decreased. Strong winds causes Electric-, Ice-, and Rock-type moves to deal neutral damage to Flying-type Pokémon.
Shadowy aura N/A Any Pokémon that is not a Shadow Pokémon will be damaged for 1/16 of its maximum HP.

This weather condition is only present in Pokémon XD: Gale of Darkness and has no overworld manifestation anywhere.

Pokémon Legends: Arceus

Weather In-game description Details
Strong sunlight The Speed of Grass-type Pokémon is boosted. Increases the Speed of Grass-type Pokémon. Activates Cherrim's Sunshine Form.
Rain Damage dealt by Fire-type moves is reduced. Damage dealt by Fire-type moves is reduced.
Snow Pokémon are more likely to get frostbite, and drowsy Pokémon are more likely to fail to act. The Speed of Ice-type Pokémon is also boosted. Pokémon are twice as likely to get frostbite, and drowsy Pokémon are twice as likely to fail to act. The Speed of Ice-type Pokémon is also boosted by 33%.
Fog All moves are less accurate, apart from moves that are always sure to hit. A thick fog clouds the overworld and battlefield, reducing the accuracy of all moves.

Moves affected by weather

Certain specific moves are also affected in special ways by the weather.

  • The recovery moves Synthesis, Morning Sun, and Moonlight restore more HP than usual in harsh sunlight, and less than usual in most other weather.
    • In Generation II, during no weather they normally restore ¼ total HP, during harsh sunlight they normally restore ½ total HP, and during other weather they normally restore ⅛ total HP. Except in link battles, the amount of HP restored is doubled if it is the move's preferred time of day (morning for Morning Sun, day for Synthesis, night for Moonlight).
    • From Generation III onward, during no weather or strong winds they restore ½ total HP, during harsh sunlight they restore ⅔ total HP, and during other weather they restore ¼ total HP.
  • The move Shore Up restores ⅔ of the user's total HP during a sandstorm; outside of a sandstorm, it only restores ½ total HP.
  • The accuracy of Thunder, Hurricane, Blizzard, Bleakwind Storm, Wildbolt Storm, and Sandsear Storm are affected by the weather.
    • From Generation IV onward, during hail Blizzard ignores accuracy and evasion checks.
    • During rain, Thunder and Hurricane ignore accuracy and evasion checks; during harsh sunlight, Thunder and Hurricane only have 50% accuracy.
    • In Generation IX, during rain, Bleakwind Storm, Wildbolt Storm, and Sandsear Storm ignore accuracy and evasion checks.
    • In Pokémon Diamond and Pearl only, Blizzard and Thunder also have a 30% chance to hit through Protect or Detect when used in hail or rain, respectively.
  • Solar Beam and Solar Blade become one-turn moves in harsh sunlight, skipping their charge turn; in rain, sandstorm, hail, and fog, the moves' powers are halved.
  • From Generation V onward, during harsh sunlight Growth increases the user's Attack and Special Attack by two stages each instead of one.
  • In Generations IV and V, and Pokémon X and Y, when used as a field move Sweet Scent fails if there is a non-aesthetic weather effect in the area.
  • The move Aurora Veil can only be used successfully during hail or snow; otherwise it fails.

Activated Abilities

The following Abilities are activated when a type of weather comes into effect. Most of these Abilities have no effect if no weather is active.

Sandstorm Hail/Snow
Forecast Forecast Sand Veil Forecast
Dry Skin Dry Skin Sand Rush Ice Body
Chlorophyll Hydration Sand Force Snow Cloak
Flower Gift Rain Dish Slush Rush

In addition to the above Abilities, Harvest is guaranteed to restore a Berry whenever it triggers in harsh sunlight, and the Abilities Overcoat and Magic Guard will prevent weather-related damage.

Castform and Weather Ball

Main article: Castform (Pokémon)
Main article: Weather Ball (move)

Castform is a Pokémon uniquely designed to take advantage of the weather. Its Ability, Forecast, causes it to change form when a type of weather is present. Forecast does not cause a unique change for every possible type of weather, though.

Weather Ball is a move that uniquely takes advantage of the weather. In Generation III, it was introduced along with Castform and was Castform's signature move.

Whenever there is a type of weather present, Weather Ball's base power will double to 100. Weather Ball's type also changes during most types of weather.

Because of its Ability, Castform has a unique synergy with Weather Ball that no other Pokémon that can learn Weather Ball has. In harsh sunlight, rain, or hail, Castform will always get STAB thanks to its Ability.

Causing weather

Most of the types of weather have a move or Ability that will cause that weather.

Move Defog* Sunny Day Rain Dance Sandstorm Hail Snowscape
Chilly Reception
Shadow Sky
Ability Drought
Orichalcum Pulse
Desolate Land Drizzle Primordial Sea Sand Stream
Sand Spit
Snow Warning Snow Warning Delta Stream

Air Lock and Cloud Nine also suspend the effects of weather while they are active.

Weather normally lasts for 5 turns when it is called by a move. Prior to Generation VI, weather created by an Ability would continue until the battle ended or another type of weather took its place; since Generation VI, weather created by Abilities also lasts for only 5 turns, with the exception of weather created by Desolate Land, Primordial Sea, and Delta Stream. As of Generation IX, moves and Abilities that change the weather will fail if a weather condition is occurring in the overworld.

If multiple Pokémon with Abilities that change the weather are sent in simultaneously, the Abilities activate in order from fastest Pokémon to slowest Pokémon (or the reverse during Trick Room); this means that the slowest Pokémon's Ability will override the other Abilities.

If a Pokémon holding one of four held items creates weather that would otherwise last 5 turns, it instead lasts 8 turns. The rock that affects each type of weather is shown below.

Visual indicators

Generation V

In Generation V, the weather was given an icon which appeared on the DS or 3DS's bottom screen in a battle whenever weather was occurring. Since fog and shadowy aura do not appear in-battle in Generation V, they have no icons. When there is no weather, no icon is shown.

In Generation VI onwards, the background of the bottom screen shows an animation of the current weather.

Generation VII

In Pokémon Sun, Moon, Ultra Sun, and Ultra Moon, the 3DS's bottom screen displays an icon and background animation of the current weather.

Generation IX

In Pokémon Scarlet and Violet, weather conditions can be seen in-battle by pressing Y for Check Status, listed under "Active Battle States and Effects". Weather conditions caused by the overworld will not display a duration, and they may appear or disappear without notice as the overworld weather changes.

Overworld

This section is incomplete.
Please feel free to edit this section to add missing information and complete it.

Overworld weather varies between games. There are a larger variety of overworld weather conditions compared to a battle, however some conditions do not affect battles. If a weather condition is present in a Route, sector of the Wild Area or location within Pokémon Legends: Arceus or Pokémon Scarlet and Violet, the weather will appear in every battle and last until it is replaced by another weather, and returns to the original weather in the overworld. In addition, Defog may clear fog from an overworld area (in Sinnoh only).

Diamond Dust is a special, purely aesthetic version of light snow, and replaces hail where applicable, allowing the player to battle without the effects of hail, without changing the weather manually. It first appeared as an Easter egg in Pokémon Diamond and Pearl, and has appeared in several core series games since.


Weather-dependent evolution

Starting at level 50, Sliggoo (as well as its Hisuian form) will evolve into Goodra if it is leveled up during rain or fog in the overworld.

Johto

Hoenn

In Hoenn, several areas have weather conditions that occur naturally:

  • Fog is present at the summit of Mt. Pyre, but it has no effect in battles.
  • There is always a sandstorm on Route 111
  • It frequently rains on Route 119, with clear skies only on one in four days.
  • It always rains on a section of Route 120 between the two log bridges corresponding roughly where the Ancient Tomb is located.
  • It rains on one in four days in Route 123 - at the same time, the rain on Route 119 will be thundery.

Several weather conditions are also triggered by in-game events:

  • When Kyogre is awakened, a rain/heavy rain is present. In contrast to natural rain, rain summoned by Kyogre includes thunderstorms as well as more rain.
  • When Groudon is awakened, harsh sunlight/extremely harsh sunlight is present.
  • Pokémon Emerald involves both Groudon and Kyogre being awakened in that order. Groudon is awakened first but does not immediately change the weather; once Kyogre is awakened, the weather will alternate between rain and harsh sunlight.

The requisite visit to Seafloor Cavern to defeat MaxieROR/ArchieSEAS will subsequently awaken Groudon/Kyogre and cause the respective weather condition to affect four cities: Lilycove City, Mossdeep City, Sootopolis City and Ever Grande City, as well as their connecting routes east of Lilycove. In Pokémon Emerald, after reaching the Sky Pillar during the crisis, its unique weather distortion will spread to the routes east of but not including Pacifidlog Town as well. While the weather condition is present, a different background music plays, overriding the usual city and route themes as well as the surfing and cycling themes.

Sinnoh

Unova

In Unova, seasons play a significant role in what weather conditions can form in the overworld.

In Generation V, it is possible to temporarily remove overworld weather by saving the game, setting the DS's clock to one month later (to change the season), loading the save file, and catching a Pokémon without leaving the area. This works even if the area always has the same weather regardless of the season.

Kalos

Alola

Rain will occur in several locations, and depends on certain conditions:

Galar

In Pokémon Sword and Shield, overworld weather effects mostly occur in the Wild Area, Isle of Armor, and Crown Tundra, including those that do not directly correspond to the in-battle weather mechanic.

Icon Weather Pokémon Effect in battle
Clear Clear (はれ) Normal, Grass, Flying
Cloudy Cloudy (くもり) Fighting, Poison, Dark
Rain Rain (あめ) Water, Bug Rain
Thunderstorm Thunderstorm (豪雨) Water, Electric, Dragon Rain, Electric Terrain
Snow Snow (ゆき) Ice Hail
Blizzard Blizzard (吹雪) Ice, Steel Hail
Harsh sunlight Harsh sunlight (ひでり) Fire, Ground Harsh sunlight
Sandstorm Sandstorm (砂嵐) Ground, Rock Sandstorm
Fog Fog () Psychic, Ghost, Fairy Misty Terrain

Reason: How much is accuracy reduced in Fog? 33% like with the Obscured status?

In Pokémon Legends: Arceus, weather is a mechanic that is completely controlled by the environment, and it is reset each day. Weather plays a role in the spawn distributions of wild Pokémon and also has certain in-battle effects. There are no moves that can affect the weather.

Icon Weather Effect in battle
Clear Sunny The Speed of Grass-type Pokémon is boosted by 33%.
Cherrim's Sunshine Form will be active.

In the spin-off games

Pokémon Mystery Dungeon series

Main article: Weather (Mystery Dungeon)

Various weather effects appear in certain dungeons in the Pokémon Mystery Dungeon series. Weather effects can change from floor to floor, and can also be altered through the use of Wonder Orbs. In Gates to Infinity, Pokémon will regenerate HP only if the weather is Clear, or if it is holding a Weather Band. In Super Mystery Dungeon and Rescue Team DX, Pokémon can regenerate HP in any weather as long as they do not take damage from the weather condition, or if it is holding a Weather Looplet.

Pokémon GO

Main article: Weather (GO)

Various weather effects appear in Pokémon GO, intended to reflect the actual weather. Weather in each local area is updated every hour, on the hour, via Accuweather. Each weather offers various weather boosts to Pokémon belonging to specific types.

Pokémon Masters EX

Main article: Weather (Masters)

Weather functions similarly in Pokémon Masters EX as it does in the main series games, though some of the effects are slightly tweaked.

  • Sunny: Boosts Fire-type attacks by 50%. Additionally, Pokémon cannot be frozen, and previous Pokémon that were frozen prior to the weather condition being implemented will not be frozen anymore after the weather takes effect.
  • Rain: Boosts Water-type attacks by 50%.
  • Hail: Damages Pokémon after every action.
  • Sandstorm: Damages Pokémon after every action.
