Pokémon GO Weather Explained
Pokémon GO uses an in-game weather system that affects boosted types, wild encounters and raid catches. The seven main categories are Clear, Partly Cloudy, Cloudy, Rainy, Snow, Windy and Fog. Each one boosts a different group of Pokémon types.
For casual players, weather is mostly a background feature. For raid-focused players, it can be a strategy tool. Knowing the active weather helps you decide which raids are more valuable and which cities may be worth checking during events.
How weather affects Pokémon
When a Pokémon type matches the active weather, that Pokémon can be weather boosted. This can make wild Pokémon appear at higher levels and can make raid bosses available at a higher catch level. The boost does not guarantee better IVs, but it can make a Pokémon cheaper to power up.
Spawns, catches and moves
Weather can affect wild appearances and the Stardust bonus. In battle, the weather boost is associated with the move’s type, so some attacks on your team may match while others do not. Source: official Pokémon GO support.
Why raid players care about weather
Legendary Pokémon are often only available for short periods. If Rayquaza, Necrozma, Kyogre, Groudon or Darkrai is in raids, players may want the best possible catch opportunities. Weather boost is one way to improve the value of a raid session.
Why in-game weather can differ
Pokémon GO weather can differ from the sky outside or a weather app. Official support notes that in-game weather can sometimes be incorrect or unavailable.
How PogoWeather estimates it
PogoWeather uses forecasts to offer estimates without reading the game’s weather directly. Always check Pokémon GO’s icon before relying on a result.
