King tides in Maine, 2027

Temporary partial data

Some station-year predictions are still loading

This page currently shows the NOAA station calendars that completed inside the response window. Try again shortly for the complete statewide calendar.

The biggest predicted tide in Maine in 2027 reaches 20.3 ft above MLLW at Coffins Point on Tuesday, July 6, at 1:28 AM local time. Below are the currently available king tide windows — the top 1% of predicted highs — for NOAA reference stations along the Maine coast. King tides are perigean spring tides: they arrive when a full or new moon lines up with the moon's closest approach to Earth, and they preview the flooding that sea level rise will make routine.

NOAA CO-OPS harmonic predictions, datum MLLW, station local time. Actual water level can run higher with storms, onshore wind, and low pressure — king tide + storm is the flooding combination to watch. Predictions are for planning, not navigation.
