King tides in Alaska, 2027
The biggest predicted tide in Alaska in 2027 reaches 17.0 ft above MLLW at Aguchik Island, Kukak Bay on Saturday, January 23, at 2:48 PMlocal time. Below are all of the year's king tide windows — the top 1% of predicted highs — for NOAA reference stations along the Alaskacoast. 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.
