Pokémon Go will cap the month with the Mega Gyrados Raid Day

Make a Splash in Mega Gyarados Raid Day — Limited-Time Power & Shiny Chances

Pokémon Go surges into action with Mega Gyarados Raid Day on Sunday, August 31st, delivering a packed three-hour event perfect for Trainers chasing rare encounters and high-value rewards. Fresh off the Max Finale weekend, this special raid rotation brings Mega Gyarados into the spotlight more frequently, with boosted Shiny odds and exciting opportunities for cooperative battles—an ideal moment for players searching for “best Pokémon Go raid events” or “how to get Shiny Gyarados fast.”

During this Raid Day, every captured Gyarados will know the Charged Attack Aqua Tail, giving you a strategic battling edge. Remote Raid Pass limits rise to 20 from August 30–31, and spinning Gym Photo Discs grants up to five extra free Raid Passes, totaling six during the event window. Whether you’re aiming to optimize your team or follow a “Pokémon Go Mega raid guide for beginners,” this day has something for every Trainer.

Looking for more? The $4.99 event ticket adds eight bonus Raid Passes from Gym spins, higher Rare Candy XL drops for Trainers level 31+, +50% raid XP, and double Stardust for all three hours. The Pokémon Go Web Store also offers a Mega Gyarados Raid Day Ultra Ticket box for the same price, bundling the event ticket and a free Premium Battle Pass. Prefer to stay free-to-play? Don’t forget you can redeem Pokémon Go codes for extra freebies.
