How to use raid weather boosts
Weather boosted raid bosses can be caught at a higher level in Pokémon GO. This does not guarantee better IVs, but it can reduce the amount of Stardust and Candy needed to power up a strong Pokémon later.
Use the table above to find the current raid boss you care about, then click Check weather boost. PogoWeather will search cities where the matching Pokémon GO weather may be active.
