Pokemon Go Weather Week

To celebrate the arrival of the Therian Formes in Pokemon Go, Niantic is holding a special Weather Week event with a focus on weather-themed Pokemon.

At the beginning of March 2021, a new three-month-long season called the Season of Legends kicked off in Pokemon Go. During this period, the game will celebrate the most popular Legendaries and Trainers from the franchise.

The most exciting feature announced so far is the debut of Therian Forme Tornadus, Therian Forme Thundurus, and Therian Forme Landorus, the powered-up versions of the Legendary Forces of Nature trio.

There will also be a series of special events taking place throughout March, with the Weather Week being one of the most exciting, as it celebrates the arrival of the Therian Formes in the game. Here’s everything we know about the event so far.
