King Tides in Alviso

You can come out to the Don Edwards Refuge in Alviso to observe and record high King Tides!

The King Tides event is being held concurrently in two different locations on the Refuge: Alviso and Ravenswood (Menlo Park). The same content will be covered. Visit the Refuge Eventbrite page if you want to attend the Ravenswood event instead.

Join the Don Edwards Refuge’s nonprofit Friends Group, the San Francisco Bay Wildlife Society, in Alviso for a guided walk and discover how the highest tides of the year give us a glimpse into the future of sea level rise. 

We'll learn what King Tides are, how sea level rise is reshaping our coastal communities, why habitat restoration matters and how you can contribute as a community scientist. We’ll walk along Refuge trails, observe plant adaptations and discuss the impacts of rising oceans. You’ll also learn how to contribute to the California Coastal Commission's King Tides Project by uploading photos through the Survey123 app - a statewide effort to record changes to our coast and estuaries. Your photos will be added to a map of this season's King Tides photos.

You can reserve a spot at the Refuge event page here.

The King Tides also highlight the issue of urban runoff pollution. Trash, toxic chemicals, and other pollutants not normally reached by the tides will be swept into the Bay, affecting humans and wildlife. 

This interactive event is suitable for all ages and will take place rain or shine.
