SF Bay King Tides
Snap the Shore, See the Future
Every year, BCDC partners with California Coastal Commission to gather photos of King Tides. King Tides are exceptionally high tides that typically occur several times per year during a new or full moon and when the earth is closest to the moon. These tides cause water levels to increase as much as 12-inches above normal high tide. Low lying sections of our shoreline experience temporary flooding during these King Tide events. The increasing impacts of King Tides show us what permanent sea level rise might look like for communities around the Bay.
Help us document areas of flooding during King Tides using the Coastal Commission’s instructions here . Photos taken in the Bay will be added to our map.
