Pokémon GO: This Week's Special Events

Niantic’s Pokémon GO is running overlapping in-game events during the week ending May 17, with Ultra Beast raid bosses, a spring-themed event and a Deino Community Day Classic all live on local time schedules. Pokémon GO Hub’s weekly events guide says the current week includes raid changes that began on May 13 and a Community Day Classic set for Saturday, May 16. In Sunnyvale, as elsewhere in the United States, those events are accessible through the mobile game and follow local time windows. The weekly lineup combines limited-time raids with a move-locked evolution window for Hydreigon, one of the week’s main draws. ### Which raid bosses changed this week? May 13 brought a new five-star raid rotation featuring Pheromosa, Buzzwole and Xurkitree, according to Pokémon GO Hub’s weekly guide and its live raid boss tracker. Mega Glalie also returned to Mega Raids in the same rotation. The site says those bosses are available in the current pool during the week of May 11-17. (pokemongohub.net) Wednesday raid events remain part of the regular cadence. Pokémon GO Hub’s May schedule says Raid Hour runs from 6 p.m. to 7 p.m. local time on Wednesdays, which means players in Sunnyvale saw the featured bosses on that schedule in Pacific time this week. Niantic has previously described Raid Hour as a local-time event format in official Pokémon GO posts. (pokemongohub.net) ### What is happening with Deino on Saturday? Saturday, May 16, is Deino Community Day Classic, according to Pokémon GO Hub’s May events page and its event guide published May 15. The event runs from 2 p.m. to 5 p.m. local time and increases Deino spawns, with a chance to encounter a Shiny Deino and a 3× XP bonus for catches, the site said. (pokemongohub.net) Zweilous can be evolved into Hydreigon with the exclusive Charged Attack Brutal Swing during the event or for four hours afterward, through 9 p.m. local time, Pokémon GO Hub said. Niantic used the same featured-attack structure for Deino’s original Community Day in June 2022, when the company said evolving Zweilous during the event window would produce a Hydreigon with Brutal Swing.

Pokémon GO Hub’s weekly guide says the Spring Marathon 2026 event began on Tuesday, May 12, at 10 a.m. local time and runs until Monday, May 18, at 8 p.m. local time. That means players checking the in-game Today View in Sunnyvale on Friday, May 15, could see multiple concurrent event cards. (pokemongohub.net) Pokémon GO Hub’s broader May calendar places the Ultra Beast raid rotation inside a separate May 13-19 window. Its current raid page, updated this week, still lists Buzzwole, Pheromosa and Xurkitree as the active five-star bosses. ### What should players in Sunnyvale actually do in the app? Sunnyvale players can confirm the live schedule in the Pokémon GO app’s Today View and nearby raid tabs. (pokemongohub.net) Niantic said when it introduced Today View that the feature shows currently running events and separates overlapping event cards when more than one event is active. Local play matters because the game’s event windows are tied to the player’s time zone rather than a single global clock. (pokemongohub.net) For Saturday’s Community Day Classic, that means the Deino spawns and the Hydreigon evolution window will run on Pacific time for players in Sunnyvale. ### Where are the official details and the next date to watch? Pokémon GO Hub’s weekly guide and May event calendar list the event bonuses, raid bosses and timing now in effect. (pokemongolive.com) Niantic’s official Pokémon GO channels have historically published event mechanics such as local-time scheduling and exclusive evolution moves, but the current May 2026 weekly roundup surfaced here through Pokémon GO Hub’s reporting. (pokemongohub.net) Saturday, May 16, at 2 p.m. local time is the next named milestone for players chasing Deino spawns, and 9 p.m. local time is the cutoff to evolve Zweilous into a Brutal Swing Hydreigon during the Community Day Classic window.
