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 Rosario, East Sound, Orcas Island from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 7.9 ft above it and mean sea level 4.7 ft. These datums are controlled from NOAA's Friday Harbor, WA gauge. Source: NOAA CO-OPS station 9449771, established 1973, gauge removed 2015. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
