Check back in summer for the next project dates.

Join #KingTides on social media:

The California King Tides Project helps us visualize future sea level by observing the highest tides of today. You can help by taking and sharing photos of the shoreline during King Tides to create a record of changes to our coast and estuaries.

Explore a map of photos from recent King Tides.

Find out what time and how high the King Tides will be near you. Learn how to participate by uploading your photos via a web browser or with a free app. Your photos will be added to a map of this season's King Tides photos. As always, please be cautious and respect the power of the ocean, and don't disturb shorebirds that may be much farther upland than usual. Download a How to Participate flyer.
