The first series of king tides, the highest high tides of the year, is coming up on November 5-9, 2025. The second and third series of winter king tides this season are December 4-8, 2025 and January 3-6, 2026. 

King Tide events give us the opportunity to peak into the future and see what the impacts of sea level rise could look like in our coastal communities. Gaining a glimpse of tidal flooding likely to become common in the future will benefit planners, resource agencies, conservationists, and coastal citizens in preparing for these changes. 

The Washington King Tides Program, coordinated by Washington Sea Grant, has resources to learn about King Tides, including a King Tide Calendar for various coastal locations around Washington, and coastal flooding lesson plans geared towards highschool students. The King Tides Program encourages people to take precautions to ensure safety when visiting the shore during a King Tide.

Residents and visitors to Washington and Oregon’s coast are invited to capture these high water events in photos. Anyone with a camera can help document the extent of these extreme high tides and help us catch a glimpse of what sea level rise will look like in our region. Everyone is welcome to participate, just pick a place, snap a photo at the highest point of that day’s tide cycle, and share it online. Photos of King Tides can be uploaded to the MyCoast App.
