Pokémon: Brilliant Diamond & Shining Pearl

Weather Effects

Vincent Lau

This page explains the effects of weather during battle.

Introduced in Pokémon Gold and Silver, battles can be subject to varying weather conditions, depending on the moves/abilities of the Pokémon and where they’re fighting (for instance, a location that’s heavily snowing may have constant Hail).

The effects of weather will apply to all Pokémon in battle. Only one weather condition can be present at one time. If a Pokémon’s move or Ability changes the weather, it will replace the previous weather condition.

Types of Weather and their Effects

Although some of these weather conditions can seem simple at first glance, like many things in Pokémon, there’s some additional complexity…
