About the tides at St. Catherine Cove

Tides here are mixed. On average the two daily highs differ by 0.7 ft, so check which low is the lower one before you head out. The pattern follows the reference station at Unalaska, Dutch Harbor. The average range is about 2.7 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 27, with a range of 5.5 ft. Neap tides follow on October 25, when the range shrinks to 0.9 ft. In the next 12 months the highest predicted tide here is 6.3 ft on December 23, and the lowest is −2.1 ft on June 6.

St. Catherine Cove is a subordinate station. NOAA predicts its tides by adjusting Unalaska, Dutch Harbor: 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 32 m later. For tidal currents, see Bechevin Bay, off Rocky Point.

Predictions are based on Unalaska, Dutch Harbor.
