Forecast (Japanese: てんきや Weatherman) is an Ability introduced in Generation III. It is the signature Ability of Castform.

Effect

In battle

During weather conditions, Forecast will change the type of a Castform with this Ability. The type of a Pokémon with this Ability will change as follows:

• It will become Fire-type if it is sunny.
• It will become Ice-type if it is hailing.
• It will become Water-type if it is raining.
• It will return to being Normal-type if there is a sandstorm, it is foggy, Shadow Sky is in effect, the weather returns to normal, or a Pokémon with Cloud Nine or Air Lock comes onto the field.

This Ability is made specifically for Castform, so if another Pokémon obtains this Ability, it will have no effect. Conversely, if Castform loses Forecast, it will be stuck in whatever form it was in at that time until it regains Forecast.

If a Pokémon with this Ability has its type changed through other means, such as Soak or Conversion, its type will be reverted to match that of the current weather condition at the end of the turn.

Outside of battle

Forecast has no effect outside of battle.
