Weather (GO) - Bulbapedia, the community-driven Pokmon encyclopedia

From Bulbapedia, the community-driven Pokémon encyclopedia.

There are several weather effects in Pokémon GO. They are intended to reflect the actual weather of the player's location. Weather in each local area is updated every hour, on the hour, via Accuweather.

Effects

Different weathers affect certain Pokémon types, and effects include:

• Increasing the power of moves of boosted types in Gym and Raid Battles by 20% (rounded down to the nearest integer)
• Wild Pokémon with a weather-boosted type...
  • spawn more frequently
  • award 25% extra Stardust when caught
  • are guaranteed at least 4 IVs 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 Shadow Pokémon)
  • have a swirling, white aura in the overview map
• The form of wild Castform depends on the weather
• The form of wild Cherrim depends on the weather
  • Cherrim appear in Sunshine Form during sunny/clear weather and Overcast Form otherwise
• Sliggoo requires rainy weather or a nearby Rainy Lure Module to evolve into Goodra

Weather bonuses are not applied for Pokémon encounters from Field or Special Research and GO Battle League rewards. Bonus damage is also not applied in Trainer Battles, 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.

  • Lotad's evolutionary family exclusively spawned in rainy weather
