If you sail Sea of Thieves for Season 20's Custom Seas tools, the official July 2026 Update Trailer is the highlight reel. The useful part sits in Rare's monthly schedule: patch 3.8.1 on Thursday, July 23, then a stacked reward weekend after it.
This is the calendar-plus-patch checklist for crews who already live in Custom Seas and want to know what actually changed versus what the trailer only teases.

The Xbox-posted trailer packages the July drop for presentation and tone. Use Rare's written July note and the in-game 3.8.1 patch notes for dates and UI changes.
What Rare confirmed for July 23
Rare's This Month in Sea of Thieves: July 2026 post is explicit about the monthly update:
The next one will arrive on July 23rd, and is set to introduce some adjustments and improvements to the Custom Seas experience, a bundle of fixes across the board and of course new cosmetic offerings in the Pirate Emporium and Outpost shops!
Rare also reminds players that monthly updates continue even though Seasons no longer use the old three-Act structure.
The shipped 3.8.1 notes fill in the Custom Seas utility the trailer glosses over, including:
Usability, text, localisation, and UX fixes across the Command and Quick Command menus
Ability to rename Custom Seas presets before a preset is selected
Continued Free Camera and Legendary Locations work inside the Custom Seas toolkit
