Groudon Raid Hour — Pokémon GO

Pokémon GO players get one hour Wednesday evening to chase Groudon in concentrated five-star raids at local Gyms. (pokemongohub.net) The April 2026 schedule lists Groudon for Raid Hour on Wednesday, April 22, from 6:00 p.m. to 7:00 p.m. local time. A separate weekly roundup published April 18 also names Groudon for that same one-hour window, even though another line on the page incorrectly labels April 22 as Tapu Koko Raid Hour. (pokemongohub.net 1) (pokemongohub.net 2) That conflict matters because the broader April raid rotation shows Groudon left five-star raids on April 21, with Tapu Koko taking over from April 22 to April 28 at 10:00 a.m. local time. The monthly Raid Hour guide, however, still slots Groudon into the April 22 featured hour and Tapu Koko into April 29. (pokemongohub.net 1) (pokemongohub.net 2) Raid Hour is Pokémon GO’s weekly Wednesday event, when the current featured legendary appears across gyms from 6:00 p.m. to 7:00 p.m. local time. Pokémon GO Hub’s April guide says these bosses appear in increased numbers in five-star raids during that hour. (pokemongohub.net) For players deciding whether to go out, Groudon is a pure Ground-type legendary raid boss. Pokémon GO Hub lists Grass-, Ice-, and Water-type attackers as its main counters, and says sunny weather boosts Groudon’s catch Combat Power. (pokemongohub.net) (pokemongohub.net) Groudon also matters beyond a single catch because Niantic’s Help Center says Primal Energy for Groudon comes from defeating Primal Groudon in Primal Raids, not standard legendary raids. Niantic says players who beat a Primal Raid catch the Pokémon in its standard form afterward. (niantic.helpshift.com) (pokemongolive.com) Shiny Groudon is available, according to Pokémon GO Hub’s database and raid guide. The site lists Groudon’s standard maximum Combat Power at 4,652 and recommends Mud Shot with Precipice Blades as its best moveset. (pokemongohub.net) (pokemongohub.net) The practical takeaway is simple: check nearby gyms at 6:00 p.m. local time and expect possible confusion because April 22 sits on the handoff day between Groudon and Tapu Koko. Pokémon GO Hub’s own pages point in two directions, but its monthly schedule and Raid Hour calendar both place Groudon in the spotlight for Wednesday’s one-hour run.
