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 Chatham Harbor, Aunt Lydias Cove from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 5.2 ft above it and mean sea level 2.5 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 2.5 ft above MLLW here, so a water level on this page converts to NAVD88 by subtracting that amount. These datums are controlled from NOAA's Nantucket Island, MA gauge. Source: NOAA CO-OPS station 8447435, established 1955. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them. The observed line is the gauge's own six-minute water level feed.
