Check out this map of tide times and locations across California and read more about how to take and share your photos of King Tides.


The California King Tides Project helps people visualize how sea level rise will impact their lives. Via smartphones and social media, we invite everyone to document the highest high tides of today, which will be the average water levels of the future.
It’s easy to participate. Just pick a location, grab a camera or smartphone, and share your photos. Photos will be used to support citizen science efforts, to communicate about the effects of flooding today, and to spread awareness about the importance of protecting communities in the future.
