What is Max Monday in Pokémon GO?
Max Monday is a weekly Pokémon GO event where Max Battles take center stage. These are special time-limited battles that occur at Power Spots from 6 PM to 7 PM local time, where every Power Spot features the same Dynamax Pokémon. Unlike standard Raid Battles, Max Battles have unique limitations—only Dynamax Pokémon can participate—adding a layer of strategy to your preparation.
During the July 14 Max Monday, all Power Spots will host Dynamax Wailmer, offering Trainers multiple chances to challenge and potentially catch this aquatic behemoth. It’s also an ideal opportunity to hunt for a shiny variant of Dynamax Wailmer, as the shiny form is officially available during this event.
Wailmer’s Typing: Know the Basics

Before heading into battle, it’s crucial to understand Wailmer’s elemental strengths and weaknesses:
-
Type: Pure Water
-
Resistances: Fire, Ice, Steel, and Water
-
Weaknesses: Electric and Grass
Avoid bringing Fire or Ice-type attackers—Wailmer shrugs those off. Instead, focus on Electric and Grass Pokémon, which exploit Wailmer’s vulnerabilities and deal significant damage during the limited battle window.
Top Dynamax Counters for Wailmer
Since Max Battles only allow the use of Dynamax Pokémon, your choices are slightly restricted compared to standard Raids. Still, there are several standout counters that can reliably turn the tide in your favor:
1. Dynamax Venusaur Line (Bulbasaur, Ivysaur, Venusaur)
Classic Grass-types with strong sustainability and high STAB (Same Type Attack Bonus) moves like Vine Whip and Frenzy Plant. Venusaur especially shines with its balance of durability and damage.
2. Dynamax Grookey Line (Grookey, Thwackey, Rillaboom)
Rillaboom, with its hard-hitting Wood Hammer and strong bulk, is an ideal counter. It’s a great pick for Trainers who have invested in the Galar starters.
3. Dynamax Toxtricity
Though not a Grass-type, Toxtricity brings the Electric pressure Wailmer struggles with. Its fast-charging Electric-type attacks and solid stats make it a reliable choice for solo or group play.
4. Dynamax Zapdos
As a Legendary Electric/Flying Pokémon, Zapdos boasts both speed and power. It’s one of the top-tier choices thanks to its heavy-hitting Thunderbolt and decent survivability.
5. Dynamax Raikou
This Johto Legendary offers consistency with moves like Wild Charge, and its bulk allows it to survive Wailmer’s water-based retaliation longer than most Electric-types.
Can Dynamax Wailmer Be Shiny?
Yes, Shiny Dynamax Wailmer is available during this Max Monday event! While shiny encounters are still rare and not guaranteed, each successful battle gives you a chance to catch Wailmer—and possibly its shiny version.
To increase your odds:
-
Participate in multiple battles within the event hour.
-
Team up with friends to speed up battles and maximize encounters.
-
If you’re still unlucky, consider local trading with other Trainers who scored a shiny Wailmer—global trades aren’t supported in Pokémon GO yet.
Pro Tip: Join local Discord groups or browse the Pokémon GO subreddit to connect with trustworthy Trainers for potential trades.
