COASTWEEKS is an annual celebration of our coastal and water resources, launched by California Coastal Cleanup Day on September 16th when tens of thousands of Californians will come together to keep our coasts and inland waterways free of debris.

Below you will find a calendar of events collected from throughout California to help you celebrate COASTWEEKS. The majority of these events are free. Please contact the host organizations for more information and to confirm the details. To add your event to the calendar, please send details by email. This calendar is growing, so check back often!

Have fun, and enjoy our Coast and Waterways!

The list below is organized by date. Switch to a list organized by location.

Inclusion in this calendar does not necessarily indicate Coastal Commission support of the policies or programs of the organizations, which are independently responsible for their events.
