About Thorne Island, Whale Passage tides
Thorne Island, Whale Passage is a NOAA subordinate station (9450938): NOAA predicts its times and heights from Ketchikan (9450460) 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, Thorne Island, Whale Passage has two highs and two lows on 26 days and three turns on 4 days, and the daily range runs from 5.9 to 23.2 ft. That is a mixed tide: two highs and two lows on most days, of clearly different heights.
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.
