Pokémon GO Mega Gyarados Raid Day: Time, Event Bonuses & More

The Pokémon GO Mega Gyarados Raid Day announcement has just been made, and you simply do not want to miss out on this one.

Amid all the major bombshell drops regarding the 2025 August GO Fest Finale and Max Battles, Pokémon GO has announced the arrival of Mega Gyarados raid day on 31st August, 2025. Similar to the previous raid days we have had, the event will kickstart at 2 PM local time and end after three hours, i.e., 5 PM local time. Given the water and dark type combination, it is a meta pick for PVE and max battles.

However, that is not the only reason why this event is a must-play for the community. In addition to collecting the mega energy and having that beautiful shiny red Gyarados on your collection that boasts excellent IVs (given it is from raids), the Gyarados caught in the raid will have the exclusive charged move Aqua Tail.

In addition to these, there have been some notable changes made for the raid day on Sunday. What are those? Let us take you through everything you need to know about the Pokémon GO Mega Gyarados Raid Day.
