Sign up to receive email about King Tides.
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. Download a How to Participate flyer.
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. If you would like to organize
an event, please email us at kingtides@coastal.ca.gov.
Each respective hosting organization is responsible for the following events. Please contact

Morro Bay is a unique estuary with a variety of environments, including pocket beaches,
rocky bluffs, sand dunes, salt marsh, freshwater creeks, and abundant wildlife. By
taking part in the California King Tide Project, your photos will help document high
water levels and improve understanding of how our coastal environments may change in
this beautiful location. During this event we invite everyone to take a snapshot of
King Tide water levels in Windy Cove and around the Morro Bay State Park Boardwalk,
so we can gain a fuller picture of how marine waters encroach upon different environments.
In Morro Bay, the peak of the King tide is predicted to occur between 9:45 and 10:05am.
We hope to see you there.
