About Bay of Waterfalls tides
Bay of Waterfalls is a NOAA subordinate station (9461337): NOAA predicts its times and heights from Sweeper Cove, Kuluk Bay, Adak Island (9461380) with offsets for this spot, so treat them as a close guide rather than an exact prediction. 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, Bay of Waterfalls has two highs and two lows on 7 days, one high and one low on 19 days, three turns on 2 days and some other count on 2 days, and the daily range runs from 2.3 to 6.3 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.
