Participate in February 2024 King Tides Project in Alviso

Very high tides known as King Tides are coming to shorelines across California Friday, February 9, 2024. King Tides are caused when there is alignment of the gravitational pull between the sun, moon and Earth. They are predictable and happen a few times of year. They are the highest tides of the year, and offer a glimpse into what life along the coast and bay could be like of sea levels continue to rise. They also provide visibility to the trash polluting our water ways and the San Francisco Bay.

The California Coastal Commission’s King Tides Project is asking for people to document the coast for a citizen-science project that aims to give decision-makers a look at how to address sea-level rise in future years.

When: Friday, February 9, 2024 - 11:00am to 12:30pm
Where: Don Edwards SFB NWR EEC, 1751 Grand Blvd San Jose, CA 95002

Sign up today to learn about this year’s King Tide events! The CCC uses the Survey123 app to track community science king tide photos.

We are inviting you as well to participate in this year's King Tides Project in Alviso!

We have a few spots at and around Don Edwards SF Bay National Wildlife Refuge where you can witness the year’s highest tides.

There are lots of other places to observe and document the King Tides. Please send us any pictures you take from the baylands in South San Francisco Bay!

The King Tides help us to visualize how future sea level rise will impact our urban areas. In addition, they also provide visibility for pollution in the SF Bay by bringing up tons of garbage onto our shorelines. For information on how you can help keep our watersheds and the Bay clean by preventing urban runoff pollution, visit: http://www.mywatershedwatch.org/
