First Ever Weather Week in Pokémon GO

Get ready for a brand new event in Pokémon GO, Weather Week! This special new event contains a huge first for Pokémon GO, a brand new shiny release that has never been available in the main series!

‘Trainers,

As the Charge Up event fills the air with electricity, we’re receiving forecasts of some wild weather on the horizon! We’re excited to announce the first-ever Weather Week event, during which Pokémon that enjoy rainy or windy conditions will be appearing more often in the wild.’

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!

From Wednesday, March 24, 2021, at 10:00 a.m. to Saturday, March 27, 2021, at 10:00 a.m. local time, Pokémon that enjoy rainy conditions will be appearing more frequently in the wild.
