The California King Tides Project helps us visualize future sea level by observing the highest high tides of today. Explore a map of photos taken during recent King Tides seasons.

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. 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.

Getting Wise to Sea Level Rise with California State Parks!
December 14, 8:30am-10:30am

Join California State Parks and the California King Tides Project for the fourth annual live stream event highlighting the winter king tides. Viewers will explore different coastal State Parks from San Diego to Eureka and learn about how king tides can predict the impacts of sea level rise along our coastline. California Secretary for Natural Resources Wade Crowfoot and Director of California State Parks Armando Quintero will join the program from China Camp State Park, and Park interpreters will present from Cardiff State Beach, Crystal Cove State Park, Gaviota State Park, Morro Bay State Park, Point Lobos State Natural Reserve, Seacliff State Beach, Van Damme State Park, and the North Coast Redwoods District.

Join the Facebook Live event on the California State Parks Facebook page OR register your classroom to watch the event as a Zoom webinar.


There is an additional, particularly high tide north of Point Conception (southwest Santa Barbara County) due to a combination of astronomical influences such as the relative tilt of the Earth's rotation with respect to the Sun and seasonal influences on water level such as temperature and wind that differ in Southern California as compared to Northern California over the course of the year.
