Ever notice how tides are so much higher in the winter than any other time of year? There’s a reason—and a name—for this phenomenon.
“King Tides” are an annual event that occur when the sun and moon align, causing an increased gravitational pull on the Earth’s oceans. And for people who study weather and climate change, these super high tides, combined with the right kind of weather conditions, give a picture of what sea-level rise might look like in the future.
Starting today, December 30, the King Tides will be at their highest. In Puget Sound, the highest tides will be this coming Sunday and Monday, January 5 and 6.
The Washington King Tides Initiative—a collaborative effort between the Washington Department of Ecology and Washington Sea Grant—needs your help documenting King Tides along Washington’s shores.
Share your King Tide photos
The Initiative is looking for photos, specifically of the higher-than-usual tides, around western Washington. The project to gather photos is aimed at documenting how very high tides affect the natural environment and our coastal infrastructure.
For information about King Tides, how to submit your photos and to see a really cool graphic explaining King Tides, visit Ecology’s Ecoconnect blog.
