About the tides at Unalga Bight

Unalga Bight usually gets one high and one low tide a day, known as a diurnal tide. The pattern follows the reference station at Adak Island, Sweeper Cove. The average range is about 3.5 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 Thursday, with a range of 4.7 ft. Neap tides follow on November 19, when the range shrinks to 2.3 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 Adak Island, Sweeper Cove: 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 Adak Island, Sweeper Cove.
