About Sweeper Cove, Kuluk Bay, Adak Island tides

Sweeper Cove, Kuluk Bay, Adak Island is a NOAA harmonic tide station (9461380): its predictions come from the tidal constituents NOAA derived from water levels measured at this spot. Heights are in feet above MLLW (Mean Lower Low Water), the datum of US nautical charts, so they line up with charted depths.

In the next 30 days, Sweeper Cove, Kuluk Bay, Adak Island has two highs and two lows on 9 days, one high and one low on 17 days, three turns on 2 days and some other count on 2 days, and the daily range runs from 2.3 to 6.6 ft. That is a mostly diurnal tide: one high and one low on most days.

Use the curve above to time a harbor entrance, a beach walk, fishing a moving tide or clearing a shallow bar, and remember that wind, air pressure and river flow can push the real water level above or below the prediction. The daily tidal range in the tables shows how much water moves each day: bigger ranges around the new and full moon mean stronger currents.
