- High tide heights run about 1.16 times the reference.
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 Shakan Strait, Kosciusko Island from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 11.5 ft above it and mean sea level 6.0 ft. These datums are controlled from NOAA's Sitka, AK gauge. Source: NOAA CO-OPS station 9450987, established 1955, gauge removed 1998. 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.
