The tide at Shell Key, northwest side, Lignumvitae Basin
Shell Key, northwest side, Lignumvitae Basin 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 0.7 ft, and 0.6 ft between the average high and the average low, a small tide. On an average day the higher high tops the lower high by 0.1 ft and the lower low sits 0.0 ft below the other low. For the water around it: The Keys sit on a tidal seam: the ocean side has two semidiurnal highs a day near 2 ft, while the bay side is smaller and more diurnal, so tides on opposite sides of one key can differ by hours.

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 Shell Key, northwest side, Lignumvitae Basin from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 0.7 ft above it and mean sea level 0.3 ft. These datums are controlled from NOAA's Key West, FL gauge. Source: NOAA CO-OPS station 8723807, established 1975, gauge removed 1975. 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.
