King Tides Marin

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!

How to participate:

1. Prepare your Smart Phone (or grab your camera!): Enable location services (GPS) on your smart phone. This can be done in Settings>Privacy on the iPhone and Settings> Location on Android.
2. Take a Photo: Go to the highest wet water line, take two steps away from the water, and take a photo parallel to the shoreline – ideally with some structure or other recognizable context in background. 
3. Note down key data: include the time, date, location, and photo orientation when you upload your photo.
4. Share your photo one of the following ways: 

• Flickr: set your photo share to “public” and submit your photo to California King Tides Flickr Group
• Facebook: publicly post your photo on Marin County Facebook page and tag with #kingtides and #marinslr. 
• Email photos to MarinSLR@marincounty.org
  

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
