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.


Join a King Tides event:

Observe and document King Tides on your own or join a group event. Events will be posted throughout the season, so check back for more. Each respective hosting organization is responsible for the following events. Please contact them for further details.

    Baylands Nature Preserve, 2560 Embarcadero Road
    Jan. 21, 10:30am-11:30am
    Presented by artist Jeffrey Downing and Palo Alto Art Center
    Bay Area artist Jeffrey Downing will create a temporary, site-specific performance near the Lucy Evans Baylands Nature Interpretive Center and Environmental Volunteers Eco Center to engage the community around the topic of sea-level rise. Downing will install his black-and-white ceramic columns, enhanced with nautical symbols at the top, in the Baylands, to coincide with the King Tides. The columns will be placed in the bay mud at the edge of the levee in front of the Nature Center. Over the course of the rising tides, the works will seemingly submerge further into the water, only to be removed when low tide returns. During the installation, the artist will be available to talk to viewers about his work and process. The site of the installation has been identified to minimize any impact to plants or wildlife habitat at the Baylands. Special care will be taken to minimize the artist's movement in areas outside pedestrian pathways to reduce any lasting impact to the environment. Downing's sculpture Terrametric Markers, 2020, will be on view at the Palo Alto Art Center in the Under Water exhibition from January 21 to April 8, 2023. For more information about this project, contact Karen Kienzle, Art Center Director at (650) 617-3535 or karen.kienzle@cityofpaloalto.org.
