About the tides at Bay of Waterfalls
Expect two roughly equal high tides a day at Bay of Waterfalls, each arriving about 50 minutes later than the day before. The pattern follows the reference station at Sweeper Cove, Kuluk Bay, Adak Island. On a typical day the water moves about 2.5 ft between high and low. That is smaller than most Alaska stations on this site. Looking a year ahead, predictions peak at 5.3 ft on December 23 and bottom out at −1.7 ft on June 6.
Tides here are worked out from the reference station at Sweeper Cove, Kuluk Bay, Adak Island, with NOAA time and height corrections. Times are good for planning, but local wind can shift them. The nearest other station is Unalga Bight, 10 mi away, where high tide comes about 1 h 13 m later. For tidal currents, see Adak Strait, off Argonne Point.
Predictions are based on Sweeper Cove, Kuluk Bay, Adak Island.
