Big Changes Come to Pokémon GO! (official PR)

Get ready to do a lot more exploring as Pokémon GO introduces a huge update that will expand your Pokédex and change the way you play! Dozens of new Pokémon originally discovered in the Hoenn region are appearing for the first time. Now you'll be able to catch Treecko, Torchic, Mudkip, and many others, with even more Pokémon waiting to be discovered in the next several weeks.

Pokémon from the Hoenn region aren't the only new addition to Pokémon GO. The game also introduces a dynamic weather system that affects how Trainers discover, catch, and interact with Pokémon! Now the in-game map will be updated with cool new weather visuals based on your local weather patterns. The real-world weather also influences which Pokémon you're likely to discover. For example, Water-type Pokémon will be more plentiful during rainy weather.

Likewise, attack types are affected by certain weather conditions. A Charizard with Fire Spin, for example, will attack with even greater heat when battling on a sunny day. Now, rain or shine, you're bound to have new—and even more exciting—Pokémon GO adventures!
