Pokémon Scarlet and Violet Reveal Summer Water Events

As Pokémon Scarlet and Violet keep rolling out live events well into the summer, trainers are getting another reason to log in: a new Water-type campaign is arriving soon, starting with an unexpected Seven-Star Tera Raid boss.

Water-type summer event starts with a surprise Tera Raid

The Pokémon Company says Pokémon Scarlet and Violet are not finished with Tera Raid and Mass Outbreak activity yet, and the next wave is themed around Water Pokémon. The first major highlight is a Seven-Star Tera Raid featuring a Dragon-type Magikarp.

This raid begins Thursday, July 16 at 8:00 PM Eastern and runs until Thursday, August 6 at 7:59 PM Eastern. During the window, players can battle and catch the featured Magikarp variant in Tera Raid dens across Paldea.

The event also continues the broader summer pattern of special raid bosses and timed availability. Earlier Seven-Star Tera Raids have been weekly since early 2026, including returning raid Pokémon such as Hisuian Decidueye the Unrivaled. As of the source’s writing, trainers have until July 16 to catch Hisuian Samurott the Unrivaled in Tera Raids around Paldea.

Mass Outbreaks across Paldea, Kitakami, and the Terarium

Alongside the Magikarp raid, Water Pokémon Mass Outbreaks will take place across multiple regions tied to Pokémon Scarlet and Violet. The outbreaks span Paldea, Kitakami, and the Terarium, with each Water-type species having an increased chance to appear with a special mark during the event.

The source lists several outbreak locations and Pokémon. Casseroya Lake will host waves of Tatsugiri, Dondozo, and Vuleza. Elsewhere in Paldea, players can expect outbreaks of Slowpoke and Psyduck at various spots.

Kitakami’s portion of the event includes Feebas and White-Striped Basculin outbreaks. In the Terarium, Lapras is set to appear more often throughout the summer event.

To further improve odds of finding a Pokémon with a special mark during Mass Outbreaks, trainers can prepare a sandwich that grants the “Title Power: Water” buff.

How to approach Magikarp the Unrivaled raid

While the featured Magikarp is positioned as a Seven-Star Tera Raid boss, the source suggests the move set is fairly limited if no other surprises are introduced by The Pokémon Company. Magikarp the Unrivaled is expected to know Splash, Tackle, and Flail.

That matters for team-building, because Ghost-type Pokémon are immune to Normal-type attacks like Tackle and Flail. The article recommends bringing a dual-type Ghost Pokémon that also includes either Fairy, Ice, or Dragon typing, aiming to take advantage of those immunities and improve matchup reliability.

With the raid running for multiple weeks, trainers have time to prepare and farm resources before the event ends.

Summer events also overlap with a competitive season in Legends: Z-A

Pokémon Scarlet and Violet’s summer event calendar isn’t the only focus for Gen 9 players. Pokémon Legends: Z-A is also set to kick off a new Ranked Battles season in July.

The source says the fourteenth season, called “Sky Battles,” begins Wednesday, July 15. Only Flying-type Pokémon will be allowed in that ranked format. It also points to Flying Pokémon capable of Mega Evolution—such as Skarmory, Rayquaza, and Dragonite—as likely to be heavily used.

With a Water-type event arriving in Scarlet and Violet while Legends: Z-A runs a Flying-only ranked season, the timing is framed as a possible thematic nod to Pokémon Winds and Waves, even though that content is not expected until 2027.

Key points

• A Dragon-type Magikarp Seven-Star Tera Raid runs July 16 (8:00 PM ET) to August 6 (7:59 PM ET).
• Water Mass Outbreaks occur across Paldea, Kitakami, and the Terarium with a higher chance of special marks.
• A “Title Power: Water” sandwich can increase odds of finding marked Pokémon during Mass Outbreaks.
• Ghost-type dual Pokémon (with Fairy/Ice/Dragon) are recommended to counter Normal-type moves like Tackle and Flail.

Confirmed event windows and featured targets

Expert View

This kind of tightly scheduled, multi-region event rollout signals Pokémon Scarlet and Violet will keep leaning into “long-form” summer engagement rather than short bursts. For the community, the Magikarp Tera Raid’s limited expected move set may lower the barrier to entry, while the marked-pokémon incentives in Mass Outbreaks reward consistent participation over the full event window. Meanwhile, the simultaneous Flying-only ranked season in Legends: Z-A suggests The Pokémon Company is deliberately spreading competitive attention across different titles—an approach that can keep both casual grinders and ranked players active during the same month.
