Top 10 Pokémon to Prepare or Target for the 2026 Pokémon GO Water Festival
1. Arrokuda & Barraskewda
Why prepare: As one of the marquee Galar region debuts for the festival, Arrokuda will be available through Field Research rewards, Rainy Lure Modules, and the event GO Pass progression track. You will want to stock up on Pinap Berries early because it takes 50 Arrokuda Candy to evolve this Rush Pokémon into Barraskewda. Keep Rainy Lure Modules ready in your inventory to force extra spawns.
2. Cramorant
Why prepare: Making its official Pokémon GO debut, the Gulp Pokémon is a unique Water- and Flying-type that introduces a game-changing form-change mechanic directly in battle. Preparing your team composition for GO Battle League is essential since Cramorant will populate reward tracks starting at Rank 16 (with higher frequency on the premium track). Note that it will be temporarily restricted from the Competitors Cup.
3. Gyarados (and Mega Gyarados)
Why prepare: Gyarados remains an absolute pillar of both PvE raid battles and Master League PvP. Having a high-level Mega Gyarados prepared ahead of time gives you a massive candy-farming multiplier when catching other Water-types during the event. Furthermore, securing XL Candy for a Shadow Gyarados is a top priority for high-tier competitive play.
4. Blastoise (and Mega Blastoise)
Why prepare: Similar to Gyarados, Mega Blastoise is a premier Water-type attacker that facilitates bonus candy generation. Regular, Shadow, and costumed variants of Blastoise’s evolutionary line require heavy XL Candy investment for the Great and Ultra Leagues. Prepare your Mega Energy reserves now so you can instant-mega evolve right as the event kicks off.
5. Tatsugiri (All Forms)
Why prepare: Tatsugiri makes its regional appearance split across three distinct forms: the Curly Form (Europe, the Middle East, and Africa), Droopy Form (the Americas), and Stretchy Form (Asia-Pacific). Because these are strictly region-locked in one-star raids, you should coordinate with international friends ahead of time to arrange Remote Raid Passes or trade negotiations to complete your collection.
6. Psyduck (Swim Ring Costume)
Why prepare: Fan-favorite costumed variants always hold trade value, and the returning Psyduck wearing a swim ring will be heavily hunted for its Shiny variant. Clear out storage space beforehand so you can quick-catch as many wild Psyduck and costumed variants as possible without stopping to transfer mid-grind.
7. Wimpod
Why prepare: Wimpod spawns will see a healthy boost in the wild during the festival. Because Golisopod is a formidable option across Great, Ultra, and Master Leagues, you should stack up on Pinap Berries and clear out space to harvest the massive amounts of candy needed for its notoriously high evolution cost.
8. Ducklett & Dewpider
Why prepare: Scopely Explore has confirmed boosted Shiny encounter rates for both Ducklett and Dewpider during the event window. Shiny hunters should ensure they have plenty of PokéBalls and Ultra Balls ready to capitalize on these boosted odds before the timer runs out.
9. Dondozo
Why prepare: Appearing prominently in three-star raids, Dondozo is a bulky powerhouse that demands sturdy counters. Prepare your best Electric and Grass-type raid counters (such as Xurkitree, Zekrom, or Kartana) beforehand so you can comfortably solo or duo these raids quickly and maximize your raid pass efficiency.
10. Lanturn
Why prepare: Lanturn is a dominant meta pick in the Great League thanks to its exceptional defensive typing and bulk. Gathering XL Candy to optimize a Great League Lanturn is a fantastic use of your time during water-themed celebrations, especially when stacking catch bonuses.
Pro-Tips for Maximizing the 2026 Pokémon GO Water Festival event Windows
Stardust Scaling Strategy: The event features escalating Stardust and XP bonuses. The final stretch (August 22–24) yields a staggering 5x Catch Stardust. Save your Star Pieces for this window; stacking a Star Piece on top of the 5x bonus results in a massive 7.5x Stardust multiplier per catch.
GO Pass Preparation: Decide early if you want to purchase the GO Pass Deluxe ($4.99) or the Deluxe + 6 Ranks bundle ($6.99) via the Pokémon GO Web Store to secure bonus items like Ultra Balls and extra Incubators right out of the gate.
The 2026 Pokémon GO Water Festival is shaping up to be one of the most lucrative events of the year for Stardust grinding and securing rare Galar region entries. Make sure to clear your Pokémon storage, stock up on Pinap Berries, and coordinate trades for regional Tatsugiri forms early!
