About the tides at Cape Mordvinof
Tides here are mixed. On average the two daily highs differ by 1.5 ft, so check which low is the lower one before you head out. The pattern follows the reference station at Unalaska, Dutch Harbor. The range is large, about 5.0 ft on average. Flats and bars appear and vanish quickly, so keep an eye on the time. That is smaller than most Alaska stations on this site. In the next 12 months the highest predicted tide here is 8.8 ft on December 23, and the lowest is −2.1 ft on June 6.
Cape Mordvinof is a subordinate station. NOAA predicts its tides by adjusting Unalaska, Dutch Harbor: highs come about 26 min and lows about 19 min later than there. The nearest other station is Cape Sarichef, 29 mi away, where high tide comes about 1 h 21 m earlier.
Predictions are based on Unalaska, Dutch Harbor.
