King tides at Jacksonville Beach

The highest predicted waters at Jacksonville 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 Jacksonville Beach

The autumn king tides put water over the low streets in St. Augustine, which floods more often than a town that old ought to, and across the marsh roads behind Amelia Island.

This is the same seasonal high water that floods Miami. With a five-foot range here rather than two, it takes less additional weather to make it a problem.
