Pokémon GO Fest 2026’s global weekend may have happened on July 11 and 12, but the event calendar is not putting its walking shoes away yet. The post-festival program is built around Mega Evolution, splitting its oversized ambitions across Mega Ascension and the two-day Pokémon GO Fest 2026: Mega Finale.
Mega Ascension begins on August 31, 2026, at 10:00 a.m. local time and remains active through September 4 at 11:59 p.m. local time. Mega Finale follows immediately on September 5 and 6, with play running from 10:00 a.m. until 6:00 p.m. local time on both days. It is a schedule that appears purpose-built for Trainers who regard a raid lobby as less of a destination and more of a habitat.
The headline attractions are returning in sequence: Mega Mewtwo X will be available on September 5, while Mega Mewtwo Y takes over on September 6. Those two days will have no Remote Raid limit, meaning Trainers can join as many raids as they wish. Mega-Evolved Pokémon will also receive an additional CP boost over the Mega Finale weekend. Many species capable of Mega Evolution are set to appear in the wild during the event hours as well, providing a fittingly Mega-sized backdrop to the raid schedule.
For collectors who follow Pokémon across cards, games, and every other format where a pocket monster can develop a following, Mega Evolution remains one of the franchise’s most visually distinct ideas. In Pokémon GO, though, it is also a resource and raid-planning system. Mega Finale’s format leans hard into that practical side: identify the day, track the hourly habitat, find the boss you need, and try not to realize at 5:58 p.m. that you had meant to do the previous rotation.

Mega Ascension starts with a branching choice
The opening event is not only a line of raid bosses. Mega Ascension includes branching Timed Research in which Trainers choose one of three Kalos starters: Chespin, Fennekin, or Froakie. Completing that research unlocks GO Pass: Mega Finale, a choose-your-path pass with rewards intended to support Mega Evolution.
That structure makes the August 31–September 4 period the runway for the main weekend rather than merely a warm-up. The pass, the starter decision, raid opportunities, and Mega Evolution-themed rewards all point toward September 5 and 6. Timed Research is exactly what its name suggests, however: it is tied to the event window. Trainers interested in the GO Pass route should keep the local-time end date in mind rather than assuming the September weekend will retroactively cover the earlier research.
During Mega Ascension, the Remote Raid limit rises to 30. Pokémon caught from Mega Raids during this portion of the event may also have a Mega Evolution-themed Special Background. The word “may” is important here; it describes a possible catch feature, not a guarantee for every successful raid catch.
Mega Ascension raid calendar
- August 31: Mega Victreebel, Mega Dragonite, and Mega Malamar
- September 1: Mega Falinks
- September 2: Mega Skarmory
- September 3: Mega Starmie
- September 4: Mega Raichu X and Mega Raichu Y
The progression gives several newer or notable Mega forms their own date rather than burying everything in a single enormous pool. September 4 is especially busy in concept, placing both Mega Raichu forms on the schedule before each gets a dedicated habitat appearance in Mega Finale. It also means players looking for a particular boss can plan around a clear daily target instead of interpreting a giant rotating list like it is ancient Unown text.
September 5: Mega Mewtwo X and four rotating habitats
The first Mega Finale day brings back Mega Mewtwo X, while the rest of the Mega Raid roster rotates every hour through four named habitats. The sequence repeats across the eight event hours. That repeat is a major planning convenience: a Trainer who misses an 11:00 a.m. window does not lose the featured habitat for the whole day, because it returns later.
- 10:00 a.m. and 2:00 p.m. — Verdant Overgrowth: Mega Beedrill, Mega Victreebel, Mega Pinsir, and Mega Abomasnow
- 11:00 a.m. and 3:00 p.m. — Mindworks Canal: Mega Alakazam, Mega Slowbro, Mega Starmie, and Mega Medicham
- 12:00 p.m. and 4:00 p.m. — Eerie Alley: Mega Gengar, Mega Houndoom, Mega Banette, and Mega Malamar
- 1:00 p.m. and 5:00 p.m. — Circuit Plaza: Mega Raichu X, Mega Ampharos, and Mega Manectric
The September 5 slate ranges from familiar raid staples such as Mega Gengar and Mega Alakazam to the newly spotlighted forms in the lineup, including Mega Starmie, Mega Malamar, and Mega Raichu X. Mega Mewtwo X is the day’s major return, but the hourly rotation means the event is not a one-boss appointment. Players can decide whether they are chasing a particular Mega, accumulating raid catches, or simply making the most of the unrestricted Remote Raid rules.
September 6: Mega Mewtwo Y takes center stage
On September 6, Mega Mewtwo Y replaces Mega Mewtwo X as the marquee return. The habitat clock follows the same repeating pattern, changing each hour from 10:00 a.m. through 5:00 p.m. local time. The roster shifts toward Steel-, Dragon-, Dark-, and Fairy-associated favorites, with Mega Raichu Y appearing in the final rotation.
- 10:00 a.m. and 2:00 p.m. — Iron Frostworks: Mega Steelix, Mega Skarmory, Mega Aggron, and Mega Glalie
- 11:00 a.m. and 3:00 p.m. — Battle District: Mega Sharpedo, Mega Camerupt, Mega Lopunny, and Mega Falinks
- 12:00 p.m. and 4:00 p.m. — Skyline Roosts: Mega Gyarados, Mega Aerodactyl, Mega Dragonite, and Mega Altaria
- 1:00 p.m. and 5:00 p.m. — Prism Promenade: Mega Raichu Y, Mega Sableye, Mega Mawile, and Mega Audino
Skyline Roosts is likely to attract attention for its concentration of longtime fan favorites: Mega Gyarados, Mega Aerodactyl, Mega Dragonite, and Mega Altaria all share the noon and 4:00 p.m. slots. Prism Promenade then closes each cycle with Mega Raichu Y, Mega Sableye, Mega Mawile, and Mega Audino. As on September 5, every habitat gets two turns, so the schedule rewards basic calendar awareness rather than flawless attendance.
What to keep straight before the finale
The simplest way to read the full event is as two connected pieces with different Remote Raid rules. Mega Ascension runs first, lasts until late on September 4 in local time, and lifts the Remote Raid limit to 30. Mega Finale runs September 5 and 6 from 10:00 a.m. to 6:00 p.m. local time, and removes the Remote Raid limit altogether. Mega Mewtwo X is assigned to Saturday, September 5; Mega Mewtwo Y is assigned to Sunday, September 6.
For the finale’s rotating raids, the most useful preparation is to note the two daily windows for the desired habitat. September 5’s cycle begins with Verdant Overgrowth at 10:00 a.m.; September 6 begins with Iron Frostworks at the same time. Each day then advances hourly through its four environments before repeating at 2:00 p.m. The format is dense, but it is not random.
Pokémon GO remains a real-world adventure game on iOS and Android, and the local-time wording matters accordingly. Trainers coordinating with friends in other locations should remember that event hours are based on where each participant is playing. Whether the objective is Mega Energy, a particular raid catch, the chance of a Special Background during Mega Ascension, or simply the spectacle of a very busy Mega weekend, the calendar has a clear order: make the starter choice, finish the Timed Research if pursuing the GO Pass, then pick the Mega Finale day and habitat that fits the target.
And if this all feels like a very elaborate plan to collect one more thing with a slightly different visual treatment, that is an experience collectors may recognize. The Collector’s Five Stages of Buying One Small Thing may not be a raid guide, but the emotional itinerary can still look suspiciously familiar.
