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 pattern follows the reference station at Unalaska. The average range is about 3.7 ft. Spring tides add a little more at both ends. That is smaller than most Alaska stations on this site. In the next 12 months the highest predicted tide here is 7.9 ft on December 23, and the lowest is −1.8 ft on June 6.

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.
