Weather

The weather is a set of mechanics that change the battle environment, activating Abilities, modifying certain moves, and potentially damaging the Pokémon in battle or affecting their stats. In battle, weather is determined by a Pokémon creating a new type of weather with a move or Ability. Currently, the location of a battle or the overworld weather does not affect the weather in a battle. Only one type of weather may be present at a time, and only the most recent type of weather will take effect.

Although Pokémon World Online generally follows Generation V's mechanics, weather is an exception and follows Generation VI's mechanics, and thus will last for only five turns instead of being permanent when created with Abilities.
