California's highest tides are coming November 15 and 16, 2020. The term "King Tide" describes an especially high winter tide when the sun, Earth, and moon all line up. The California King Tides Project, a partnership of government and community organizations, helps us visualize future sea level rise by observing the highest tides of today and how these tides interact with our coast infrastructure, recreation areas, and ecosystems.
Follow the action this year on the Port's social media accounts to see the King Tides in action along San Francisco's waterfront and participate in the King Tides Project by posting your own photos with #KingTides or uploading to california.kingtides.net.
