Date and Time
Wednesday, March 24, 2021, at 10:00 a.m. to Monday, March 29, 2021, at 8:00 p.m. local time
Bonuses
- Catch Pokémon with Weather Boost to earn extra Stardust.
- Shiny Rainy Form Castform makes its debut in Pokémon GO
- New spring-themed avatar items will be available in the shop
Increased Wild Encounters
Castform will be appearing more frequently in the wild throughout the event, alongside other Pokémon that tend to appear when it’s either rainy and windy, like Wingull and Ducklett. If you’re lucky, you might encounter a Shiny Rainy Form Castform!
Shiny Rainy Form Castform is huge news, because it has never appeared before in any Pokémon game! This makes Castform the first ever Pokémon to be shiny in Pokemon GO before any game that existed before Pokémon GO.
While Meltan made its debut in Pokémon GO, it was a brand new Pokémon, whereas Castform has been available only as a shiny in its normal form in all other Pokémon games.
The shiny sprites for the other forms of Castform were found by the PokeMiners in 2020, and now we finally have news of the first one coming to Pokémon GO. Could we see more themed Weather Weeks in the future to release Sunny and Snowy? Who knows!
