Pokémon GO Summer Marathon: Aug 3–9, 2026

Niantic’s Pokémon GO calendar for the week of Aug. 3-9, 2026 is built around the Summer Marathon: Arctic Embers event, according to Pokémon GO Hub’s weekly schedule. The event window runs from Tuesday, Aug. 4, at 10 a.m. local time to Monday, Aug. 10, at 8 p.m. local time and includes shiny Snom’s debut, boosted shiny rates for select Pokémon, timed research and a new GO Pass. (pokemongohub.net) Pokémon GO Hub’s roundup for the week also lists a Fire and Ice Hatch Day, a regional Raid Hour, a Spotlight Hour and Max Battles during the same stretch. ### When does the main event actually run? Tuesday, Aug. 4, is the start of Summer Marathon: Arctic Embers, and Pokémon GO Hub says the event begins at 10 a.m. local time. (pokemongohub.net) The event is scheduled to end on Monday, Aug. 10, at 8 p.m. local time. Shiny Snom is the headline addition in that event window. Pokémon GO Hub says the Summer Marathon event “releases shiny Snom” and features Fire- and Ice-type Pokémon during the week. ### What is happening in the game on Thursday, Aug. 6? Thursday, Aug. 6, is Spotlight Hour for Delibird from 6 p.m. to 7 p.m. local time, according to Pokémon GO Hub’s weekly schedule. (pokemongohub.net) The listed bonus for that hour is 2x Stardust for catching Pokémon. That makes the Spotlight Hour the live one-day item in the middle of the week for players checking the schedule on Aug. 6. (pokemongohub.net) Pokémon GO Hub’s monthly August events page also lists Delibird as the featured Spotlight Hour Pokémon for the week. ### Which raid bosses are in rotation this week? (pokemongohub.net) Wednesday, Aug. 5, brought the week’s Raid Hour from 6 p.m. to 7 p.m. local time, with Uxie, Mesprit and Azelf appearing in their respective regions, Pokémon GO Hub said. The outlet lists Uxie in Asia-Pacific, Mesprit in Europe, the Middle East, India and Africa, and Azelf in the Americas and Greenland. (pokemongohub.net) Aug. 5 also marked the broader raid-pool change for the week. Pokémon GO Hub says Uxie, Mesprit and Azelf moved into five-star raids on Aug. 5, while Mega Blaziken entered Mega Raids for Aug. 5-11. (pokemongohub.net) ### What is Fire and Ice Hatch Day, and when should players log in? Saturday, Aug. 8, is Fire and Ice Hatch Day, and Pokémon GO Hub says it runs from 11 a.m. to 5 p.m. local time. The event centers on Magby and Smoochum in 2 km eggs with boosted shiny odds. The same event also includes special Timed Research tasks and a paid Timed Research track for additional encounters, according to Pokémon GO Hub’s weekly page. (pokemongohub.net) That makes Aug. 8 the most concentrated event block of the week after the Summer Marathon start. ### Are Max Battles part of the week too? (pokemongohub.net) Monday, Aug. 3, opened the week with Dynamax Magmar in Max Battles from 6 p.m. to 7 p.m. local time, Pokémon GO Hub said. The site also says Dynamax Magmar continues to appear in Max Battles from Aug. 3 through Aug. 9. Pokémon GO Hub’s August events calendar lists Max Battles as part of the month’s broader schedule alongside Community Day, Ultra Unlock: Water Festival and later raid rotations. (pokemongohub.net) That places the Aug. 3-9 week inside a larger August run of timed events rather than as a standalone mini-season. ### What comes next after this week ends? Monday, Aug. 10, at 8 p.m. local time is the scheduled end of Summer Marathon: Arctic Embers, according to Pokémon GO Hub. The August calendar then lists Nickit Community Day on Aug. 16 and Ultra Unlock: Water Festival from Aug. 13-20 as the next major events on the month’s slate. (pokemongohub.net) (pokemongohub.net)
