About the tides at Unalga Bight

Unalga Bight has a semidiurnal tide: two highs and two lows of similar height each day, about 12 hours and 25 minutes apart. The average range is about 2.5 ft. Spring tides add a little more at both ends. That is smaller than most Alaska stations on this site. The next spring tides peak on Saturday, with a range of 5.1 ft. Neap tides follow on October 10, when the range shrinks to 0.8 ft. In the next 12 months the highest predicted tide here is 5.4 ft on December 23, and the lowest is −1.7 ft on June 6.

Unalga Bight is a subordinate station. NOAA predicts its tides by adjusting Sweeper Cove, Kuluk Bay, Adak Island: highs come about 7 min and lows about 21 min earlier than there. The nearest other station is Sweeper Cove, 9 mi away, where high tide comes about 7 min later. For tidal currents, see Adak Strait, off Argonne Point.

Predictions are based on Sweeper Cove, Kuluk Bay, Adak Island.
