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 Fort Matanzas, Matanzas River, ICWW from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 4.3 ft above it and mean sea level 2.2 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 2.6 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 Mayport (Ferry Depot), FL gauge. Source: NOAA CO-OPS station 8720686, established 1973, gauge removed 1979. 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.
