Mega Evolution is finally available in Pokémon Go, and with it comes a month-long celebration that includes increased spawn rates for certain species of Pokémon, more Mega Raids, and event-exclusive Field Research. 

The Mega September event will run throughout the month, with various milestone goals set up to reward players with new Mega Evolved encounters if they are met. 

As of now, there are three sets of dates that will have rotating bonuses, including different spawn rates for Pokémon, Mega Raid challenges, or new event effects. This all starts with the first rotation from Sept. 1 to 7, where players can unlock Mega Pidgeot by completing 2 million Mega Raids globally.
