Welcome!

The California King Tides Project invites you to document the highest seasonal tides (or king tides) that happen all along the state’s coast. These king tides give us a preview of what we might experience regularly in the future as a result of rising sea levels. King tide events are an opportunity to share what you see in your community with others, and help scientists and managers better understand areas at risk. Everyone is welcome to participate!

The objectives of the King Tide Photo Project are to:

  • Engage Californians in a conversation about the future of our beloved coastal areas
  • Identify and catalog coastal areas that are currently vulnerable to tidal inundation
  • Build an online resource of images that can be used by everyone – artists, scientists, school groups, coastal planners –  to document, visualize, and communicate about coastal hazards

Our shores are constantly being altered by human and natural processes and projections indicate that sea level rise will exacerbate these changes.  King Tides images offer a living record of the changes to our coasts and shorelines and a glimpse of what our daily tides may look like in the future as a result of sea level rise.

Photos taken during King Tide events document impacts to private property, public infrastructure, and wildlife habitat across the state.  We want to continue capturing what happens during extreme high tides, and we need your help to do it!


Featured Project –  Bay Area Residents Help Scientists Make Sea Level Rise Models Better

OCOF-map-fpo-lgIn January, we partnered with USGS and the Our Coast, Our Future project to collect king tide photos from specific locations around the Bay Area.   The pictures people took are helping scientists better understand which areas are most at risk of flooding and future sea level rise.  Researchers are comparing photos of the high tide against computer simulations of flooding to see how well these simulations match reality.  This was a fun, easy way for everyday people to provide important information that will help future sea level rise adaptation planning efforts in the Bay Area.  For the original announcement, click here.

If you’d like to talk to us about setting up a similar citizen science photodocumentation project in your own area, email us!
