King tides at Chesapeake Beach

The highest predicted waters at Chesapeake Beach, through 2030. Every high tide reaching 7.00 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 Chesapeake Beach

Annapolis floods on these tides, and does so more often than it used to. The City Dock goes under on the highest waters of the year without any storm involved, which is why the town has become one of the most-studied places in the country for tidal flooding.

Add a northeast wind holding water in the bay and the same tide reaches further. The figures here are astronomical only.
