King Tides Marin

Community Development Agency

The King Tides Project helps us visualize future sea level by documenting today’s highest tides. Share your photos of Marin’s shoreline during King Tides to help us create a record of how our shoreline is changing.

Thanks to all who submitted photos of this winter’s King Tides December 4-5, 2021 and January 2-3, 2022. Check out the submitted photos gallery and stay tuned for next winter’s King Tide forecasts!

Remember to BE SAFE! 

Drive Safely During High Tides. The County of Marin’s Department of Public Works and the Marin County Flood Control and Water Conservation District are teaming with the California Department of Transportation (Caltrans) to urge residents and visitors to:

  • stay informed of changing conditions
  • research how high tides might affect travel plans
  • consider using alternative driving routes
  • avoid driving through ponded water
  • allow extra time for trips, especially during peak times of holiday and commuter travel
