King Tides & Coffee

Loading Map....

8:00 am - 10:00 am

Surfer's Beach

King tides are the highest tides of the year and help us visualize what every day water levels could look like with sea level rise. The San Mateo County Sea Change team is leading a King Tides & Coffee event to inform the public about king tides and sea level rise. At the event, County staff will share information about the current projects the County and others are working on to reduce impacts from flooding and erosion due to sea level rise. The king tide’s peak height will be 6.6 feet at 8:12 am.

The event will begin at Surfer’s Beach  and end at Miramar Beach Restaurant.

8:00 AM – Meet at Surfer’s Beach for coffee & welcome from County Supervisors Carole Groom and Don Horsley

8:20 AM – Guided walk along the shoreline with County & City staff

9:00 AM – Meet for coffee & bagels, presentations, activities, & mingling at Miramar Beach Restaurant

To reduce waste, please remember to bring your personal mug. In addition, don’t forget to bring your camera to capture the high tides!

In addition to attending the event, we encourage you to go out to the Bay or Coast during the highest tides of the year and take photos of the high water, and post them to the California King Tides website. The images shared by the public are used by State and local officials as well as climate change researchers to validate sea level rise models and better assess local flood vulnerabilities. Understanding the impacts of sea level rise is essential to finding the best way forward that balances all communities’ interests.


The event begins and ends in different locations; therefore, you have two options for parking:

1) Park at Miramar Beach Restaurant and walk to Surfer’s Beach (0.5 miles) where the event will start. The event will END at the Miramar Beach Restaurant; therefore, you can leave directly from the Restaurant if you choose to park here.

2) Park at Surfer’s Beach where the event will start. The event will END at the Miramar Beach Restaurant; therefore, you’ll need to walk back to Surfer’s Beach after the event.
