Pokémon GO Raid and Event Week

Pokémon GO’s week just flipped over, and the headliner is simple — three Ultra Beasts are now in five-star raids. Buzzwole, Pheromosa, and Xurkitree went live on Wednesday, May 13, at 6:00 a.m. local time, with Mega Glalie taking the Mega slot and a Raid Hour set for 6:00 to 7:00 p.m. the same day. ### Which raids changed today? The raid board changed on the usual Wednesday reset. Mega Camerupt rotated out, and the new lineup brought in Buzzwole, Pheromosa, and Xurkitree as the featured five-star bosses, while Mega Glalie took over Mega Raids. Those Ultra Beasts are scheduled to stay until Wednesday, May 20, at 6:00 a.m. local time. ### Why do these three matter? They are not interchangeable. (leekduck.com) Buzzwole is the muscular Fighting- and Bug-type bruiser, Pheromosa is the glass-cannon speedster, and Xurkitree is the Electric-type attacker many players still value for raids. Basically, this week is less about one marquee legendary and more about filling specific roster gaps if you missed earlier Ultra Beast runs. ### Is this actually the main event? (leekduck.com) Not exactly. The broader in-game event running right now is Spring Marathon 2026, and that is where most of the week’s non-raid action lives. It runs until Monday, May 18, at 8:00 p.m. local time and adds Flittle and Espathra to the game, plus Pikachu wearing a marathon visor. So the raids are the flashy part, but the event week is really doing two jobs at once — debuting new spawns and rotating in strong raid targets.

That matters because it slices right through the middle of this raid window. If you are trying to optimize play time, the smart split is raids on Wednesday for the Raid Hour, event grinding through the week, then Deino on Saturday before the Ultra Beasts leave next Wednesday. (leekduck.com) ### What about Cupertino specifically? There is no separate official Cupertino-only event attached to this raid rotation that I could verify. The practical reality is just that Cupertino players get the normal citywide gym map, wild spawns, and event bonuses any local community would see during Spring Marathon and the current raid cycle. If you are planning local play, the useful question is density — malls, parks, and downtown gym clusters matter more than any special city tag here. (pokemongohub.net) ### Is there any catch? Yes — time. These bosses started today, May 13, and they are gone on May 20. Then Tapu Bulu takes the five-star slot. So if you want XL candy, shinies where available, or just one good Xurkitree for your raid bench, this is a short sprint, not a monthlong farm. ### So what’s the move? Hit Raid Hour if you want the cleanest shot at the Ultra Beasts. Use the rest of the week for Spring Marathon spawns and the Flittle line debut. (pokemongohub.net) Then pivot to Deino Community Day Classic on Saturday. That is the real shape of Pokémon GO this week — one raid rotation, one broader event, and one weekend spike stacked on top of each other. (leekduck.com)
