Generations III to V
Drought summons sunlight in battle as soon as a Pokemon with Drought enters the battle. Its effects are the same as the move Sunny Day, but instead of lasting for a limited amount of turns, it lasts for the whole battle (unless it is replaced by another weather condition). If a Pokemon with Drought is sent out in the same turn as another Pokemon whose Ability affects the weather, the slower Pokemon’s Ability will override the faster Pokemon’s Ability.
The sunlight now lasts only for five turns. This can be extended to eight turns if the Pokemon is holding a Heat Rock.
Outside of battle
Drought has no effect outside of battle.
