About the tides at Usof Bay

Usof Bay has a mixed tide. The two daily highs, and especially the two lows, can differ a lot in height. The average range is about 3.6 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 7.1 ft. Neap tides follow today, when the range shrinks to 1.9 ft.

Usof Bay is a subordinate station. NOAA predicts its tides by adjusting Unalaska: highs come about 210 min and lows about 225 min earlier than there. The nearest other station is Raven Bay, 4 mi away, where high tide comes about 14 min later.

Predictions are based on Unalaska.
