August 2026 Is the Densest Month of the Summer
August 2026 packs a Gigantamax debut, a Community Day, two Ultra Unlocks, and a Super Mega Raid Day into 31 days. The month opens with Gigantamax Rillaboom (Aug 1), peaks with Nickit Community Day (Aug 16) and Water Festival (Aug 18–24), and closes with the Starmie Super Mega Raid Day (Aug 22). Here is the week-by-week calendar so you can pre-build counters and bank items.

Raid Bosses to Plan For
- Gigantamax Rillaboom (Aug 1): Grass — bring Fire, Flying, Bug, Ice, Poison.
- Mega Starmie (Aug 22): Water/Psychic — bring Bug, Dark, Ghost, Electric, Grass.
- Water Festival raids: Water-themed rotating bosses (confirm the tier list in-game as the date nears).
Spotlight & Raid Hours
The fixed weekly slots continue:
- Spotlight Hour: Every Tuesday 6–7 p.m. local (check the in-game news for the featured Pokémon — e.g., Eevee on Jul 23, Bidoof on Jul 30).
- Raid Hour: Every Wednesday 6–7 p.m. local with the rotating legendary/mega boss.
- Max Monday: Every Monday with a rotating Dynamax Pokémon (e.g., Trubbish Jul 20, Feebas Jul 27).
Resource Checklist for August
- Max Particles topped before Aug 1 (cap 1,600 during Rillaboom).
- Star Pieces saved for the Aug 22–24 Water Festival 5× Stardust peak.
- Lures & Incense stocked for Nickit Community Day.
- Remote Raid Passes banked for Starmie (cap raised to 20).
- Fire/Grass counter teams pre-built for both Max and Super Mega days.
Final Thought
August rewards players who plan: the two biggest days (Rillaboom and Starmie) need different counter types, and Water Festival's Stardust peak is easy to miss without a Star Piece queued. Block Aug 1, 16, and 22 now, and let the Spotlight/Raid Hours fill the gaps. Happy hunting, trainers!
