During the next week the full moon associated with the summer solstice will bring extreme high tides called King Tides to our coast. The term ‘King Tide’ is a non-scientific term used to describe naturally occurring, exceptionally high tides that take place when the sun and moon’s gravitational pull align making the oceans “bulge.” While the King Tides during the summer are not as large as winter King Tides, these exceptionally high tides depict what could be the new normal as sea level rise progresses. This June high tide event marks a good opportunity to select your favorite locations to photograph both now and in December to compare!

Photos taken during king tide events document impacts to private property, public infrastructure, and wildlife habitat across the state, highlighting areas most vulnerable to sea level rise. We want to continue capturing what happens during extreme high tides, and we need your help to do it! Be safe! Take extra precautions when you walk on slippery areas or near big waves, and always be aware of your surroundings and the weather conditions.

Please participate in the Washington King Tides initiative by photographing these high tide events and uploading them to Flickr!
