About the tides at Sweeper Cove

Sweeper Cove has a semidiurnal tide: two highs and two lows of similar height each day, about 12 hours and 25 minutes apart. On a typical day the water moves about 2.9 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 3.7 ft. Over the next two weeks the biggest daily range, 5.2 ft, comes on Saturday, and the smallest, 0.9 ft, on October 10. Looking a year ahead, predictions peak at 5.6 ft on December 23 and bottom out at −1.8 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 wind and air pressure. It was established in 1943. The nearest other station is Unalga Bight, 9 mi away, where high tide comes about 7 min earlier. For tidal currents, see Kagalaska Strait, off Galas Point.
