Drag to set position!

The 2020 season's California King Tides will be January 10-12 and February 8-9. I hope you can get out and (safely!) take photos. Please Do Not select All Rights Reserved if you want your photos to be used for the King Tides Project! We are now encouraging participants to upload their photos directly via the California King Tides website at Thank you!

Group Description


Winter high tides within estuaries and along the outer coast provide a preview of the future as sea levels rise. Help document these “King Tides” by joining the photo initiative. Its objectives are to:

1. Identify and catalogue coastal areas currently vulnerable to tidal inundation; and
2. Gather compelling photos so we can promote awareness of the specific potential impacts of sea level rise on the region in order to support climate change mitigation and adaptation. The photos may be used online, in presentations, and in print.

This initiative is part of a West Coast partnership with Washington State (website, flickr) and others in Oregon and British Columbia (website, flickr).

During King Tides, take photographs of areas in California that are known to flood and erode and / or areas where the high water levels can be gauged against sea walls, jetties, bridge supports, dikes, buildings or other coastal infrastructure. Submit your photos to this Flickr group.

Submission details: Please include your contact information and geographically reference the photos with specific locations (GPS position, if possible), orientation, date and time of day. Consider what kind of licensing to add to your photos. Please do not select "All Rights Reserved," as this will limit our ability to share your photos to highlight King Tides.

Be sure to read and agree to our Group Rules, below.


California's King Tides occur during the winter months. The time of high-tide events will vary depending on where you are. Visit for King Tide heights and times at a range of locations.


Increases in global sea levels have been recorded by NOAA tide gauges for many years, and more recent observations have been collected by NASA satellites. The steady rise has been attributed to both a warming of the oceans and contributions from melting glaciers and land-based ice sheets. Climate modeling combined with these direct observations suggest sea level rise will continue well into the future with significant implications for the state’s shoreline.

Group Rules

By joining this group, you agree to the following rules:

- Be careful during high water and/or stormy conditions
- Make sure your camera is set to the correct DATE and TIME (so that metadata is accurate)
- Turn on the camera's GPS if it has one (all King Tide Photos must be referenced to geographic locations)
- When uploading photos, make sure to add descriptions to your photos and note the date and time taken, as well as the geographic location
- If the information is available to you, it would also be helpful to know which direction the camera was facing, whether the photo is a low-tide comparison, and what the tide height was above chart datum (e.g. 3.7 m)
- Please tag your photos as appropriate. We suggest using the words "King Tides," "King Tides 2016," and other identifiers such as specific location of photo (i.e. "Bolinas" or "Fisherman’s Wharf")
- We will use photos submitted to this group according to the"Attribution-NonCommercial-ShareAlike License" (
This will allow us to feature your photography in presentations, websites, publications, etc.
- All photos will be approved by a moderator before becoming available online
