King tides at Copalis Beach

The highest predicted waters at Copalis Beach, through 2030. Every high tide reaching 7.0 ft above MLLW.

What counts as a king tide

There is no official definition. NOAA does not publish one, and the California King Tides Project simply means the highest predicted tides of the year. This page lists every predicted high water of 7.0 ft or more above MLLW, which on this stretch of coast picks out the handful of days each winter when the water comes up unusually far.

They happen when the moon is closest to Earth and new or full at the same time, with the Earth near its own closest approach to the sun. That alignment stacks the solar and lunar pulls together, and it lands in November, December and January far more often than not.

These are predictions of astronomical tide only. A winter storm arriving on a king tide is what causes flooding, because surge and wind can add a foot or more on top of the figures here.

What a king tide means at Copalis Beach

Washington's King Tides Project asks for photographs on these days, because the highest tides of the year show where the water will reach when the sea is a little higher than it is now.

Storm watching is the other reason people come. A December king tide with a Pacific low behind it puts the surf over the seawalls at Westport and Long Beach, and the combination — not the tide alone — is what closes roads.
