About the tides at Sand Bay
Tides here follow a regular twice-daily rhythm. The two daily highs usually differ by only 0.4 ft. The pattern follows the reference station at Sweeper Cove, Kuluk Bay, Adak Island. The average range is about 2.3 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 October 15, with a range of 4.1 ft. Neap tides follow on Saturday, 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.
Sand Bay is a subordinate station. NOAA predicts its tides by adjusting Sweeper Cove, Kuluk Bay, Adak Island: highs come about 5 min and lows about 20 min earlier than there. The nearest other station is Bugle Point, 6 mi away, where high tide comes about 6 min later. For tidal currents, see Chugul Pass, 0.5 mile NE of Cape Ruin.
Predictions are based on Sweeper Cove, Kuluk Bay, Adak Island.
