About the tides at Unalaska

This is a mixed-tide station. Some days bring a deep low and a shallow low, and a few days have only one of each. On a typical day the water moves about 2.4 ft between high and low. That is smaller than most Alaska stations on this site. From the average lower low to the average higher high, the difference is 3.6 ft. Over the next two weeks the biggest daily range, 4.3 ft, comes tomorrow, and the smallest, 2.3 ft, on November 19. Looking a year ahead, predictions peak at 5.1 ft on December 23 and bottom out at −1.5 ft on June 6.

A live NOAA gauge measures the water here, and predictions are calculated from this station's own records. It also reports water temperature, wind and air pressure. It was established in 1955. The nearest other station is Dutch Harbor, 0.9 mi away. For tidal currents, see Iliuliuk Bay, east channel.
