King tides at East Greenwich

The highest predicted waters at East Greenwich, 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 East Greenwich

The highest tides of the year come over the low ground in Warren, Barrington and along the Providence River. Providence itself is protected by the hurricane barrier, which is closed when a surge is forecast — the only city on this coast with that arrangement.

A king tide with a southerly behind it is what pushes water up the bay. The figures here are astronomical only.
