Pokémon GO Weekly Events: May 11–17

Niantic’s Pokémon GO schedule for the week of May 11-17 is anchored by a midweek raid rotation, the Spring Marathon event and a one-day Deino Community Day Classic, according to event listings compiled by Pokémon GO Hub. The week began with Dynamax Growlithe in Max Battles on Monday, May 11, from 6 p.m. to 7 p.m. local time, and that Dynamax Growlithe run continues through May 17. (pokemongohub.net) On Tuesday, May 12, the Spring Marathon event started at 10 a.m. local time and runs until Monday, May 18, at 8 p.m. local time. On Wednesday, May 13, the five-star and Mega Raid lineups changed, bringing regional Ultra Beasts and Mega Glalie into the pool. ### Which parts of the week are still live on Thursday, May 14? Thursday, May 14, falls inside the active windows for Spring Marathon, the May 13-19 five-star raid rotation and the May 11-17 Dynamax Growlithe Max Battle rotation. For players in Aliso Viejo and other U.S. locations, that means Buzzwole is the current regional five-star boss, because the Americas are assigned Buzzwole during this cycle. The May 13 raid change also swapped Mega Camerupt out for Mega Glalie in Mega Raids through May 19, Pokémon GO Hub’s May calendar shows. Shadow Cresselia remains in weekend Shadow Raids during May 6 to June 2, according to the same calendar. (pokemongohub.net) ### What exactly changed in raids on May 13? May 13 introduced three different Ultra Beasts to five-star raids, divided by region. Pokémon GO Hub lists Pheromosa for Europe, the Middle East and Africa, Buzzwole for the Americas, and Xurkitree for Asia-Pacific from May 13 to May 19. Wednesday’s Raid Hour, held from 6 p.m. to 7 p.m. local time, used that same regional split. (pokemongohub.net) For U.S. players, including those playing locally in Southern California, the featured Raid Hour boss was Buzzwole. ### What does Spring Marathon add during this window? (pokemongohub.net) Spring Marathon began on May 12 and runs past the end of this weekly window, ending on May 18 at 8 p.m. local time. Pokémon GO Hub says the event includes the Pokémon GO debut of Flittle and the first appearance of Pikachu wearing a marathon visor, along with event bonuses, wild spawns, raids, Field Research and GO Pass rewards. (pokemongohub.net) The event timing is local, so the bonuses and research are available in Aliso Viejo on the same local schedule as elsewhere in the United States. The weekly events guide lists Spring Marathon as the main event spanning this stretch of the calendar. (pokemongohub.net) ### What is the key date for Deino this week? Saturday, May 16, is the week’s main one-day event because Deino Community Day Classic runs from 2 p.m. to 5 p.m. local time. Pokémon GO Hub says the event includes increased Deino spawns, a higher chance to encounter Shiny Deino and a 3x XP bonus for catching Pokémon. (pokemongohub.net) May 16 also carries the week’s limited-time evolution move. Players who evolve Zweilous during the event, or until 9 p.m. local time that day, can get Hydreigon with Brutal Swing, according to the event listing. (pokemongohub.net) ### Are there any missing weekly staples players should know about? May 2026 has no Spotlight Hours, according to Pokémon GO Hub’s monthly weekly-events guide. The guide says Tuesdays’ usual 6 p.m. to 7 p.m. local-time Spotlight Hour slot is canceled for the month. Monday and Wednesday weekly formats remain in place. Max Monday continues to run from 6 p.m. to 7 p.m. local time, and Raid Hour continues on Wednesdays in the same time slot. (pokemongohub.net) ### What is the next concrete deadline after this week? Monday, May 18, at 8 p.m. local time is the next hard stop because Spring Marathon ends then. (pokemongohub.net) Tuesday, May 19, is the last full day before the current Ultra Beast and Mega Glalie raid rotations change again, and Pokémon GO Hub’s May calendar lists Tapu Bulu and Mega Altaria as the next bosses beginning May 20.
