The tide at Thorne Island, Whale Passage
Thorne Island, Whale Passage has a semidiurnal tide: two highs and two lows a day of about the same size, roughly 12 hours 25 minutes apart. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 15.9 ft, and 13.6 ft between the average high and the average low, a very large tide, among the biggest in the United States. On an average day the higher high tops the lower high by 0.9 ft and the lower low sits 1.5 ft below the other low. For the water around it: Inside Passage tides are large and mixed semidiurnal, two highs and two lows a day with ranges of 12 to 20 ft that drive fast currents in the narrows.
About this station
- High tide reaches Thorne Island, Whale Passage about 9.6 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
- NOAA predicts tides here from Ketchikan, station 9450460. High tide comes about 12 min later and low tide about 1 min later than there.
Datum and source
Heights on this page are feet above mean lower low water (MLLW), the zero NOAA's nautical charts use for soundings. A predicted 0.0 ft low is the average of the lower low each day; a minus tide is water below chart datum, and a 2 ft high means 2 ft more water than the chart shows. NOAA fixes MLLW at Thorne Island, Whale Passage from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 15.9 ft above it and mean sea level 8.3 ft. These datums are controlled from NOAA's Ketchikan, AK gauge. Source: NOAA CO-OPS station 9450938, established 1967, gauge removed 2001. The tide times and heights are published as time and height offsets from its reference gauge; TidalMap republishes them daily and does not alter them.
