About the tides at St. Catherine Cove

Tides here are mixed. On average the two daily highs differ by 0.5 ft, so check which low is the lower one before you head out. The average range is about 2.4 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 6.1 ft. Neap tides follow on October 9, when the range shrinks to 2.0 ft.

St. Catherine Cove is a subordinate station. NOAA predicts its tides by adjusting Unalaska: highs come about 4 min later and lows about 18 min earlier than there. The nearest other station is Cape Chunak, 4 mi away, where high tide comes about 1 h 29 m later. For tidal currents, see Bechevin Bay, off Rocky Point.

Predictions are based on Unalaska.
