Come join your neighbors and local scientists to document the highest tides of the year!

Teams will use community science kits to explore how low-lying spots along the waterfront are affected by these extreme tides, also known as king tides. Measure flooding and take pictures alongside local experts, including guests from the Exploratorium!

San Rafael is one of the Bay Area’s most vulnerable cities to sea level rise, and the information you collect will help our community prepare.

Waterproof boots recommended!

This event is co-hosted by Canal Alliance, City of San Rafael, University of California Berkeley, and the Multicultural Center of Marin. A special thanks to California State Coastal Conservancy, the Governor’s Office of Land Use and Climate Innovation, and Marin Community Foundation for their generous support.
