Pokémon GO‘s Mega Ascension event will bring 10 raid bosses to the game on Tuesday, September 1, 2026, with Mega Latias and Mega Latios occupying the top Tier 6 slots. The event is scheduled to run from 5:00 a.m. to 8:00 p.m. local time, giving Trainers one packed raid window before the lineup ends.
The discovered schedule also places Mega Falinks in Tier 4, followed by three encounters in Tier 3 and four more in Tier 1. Since the entire event lasts only 15 hours, the local-time cutoff is the detail to keep in mind.
