Boot Key Harbor bridge, Boot Key sits at 24.7033° N, 81.1050° W on the Florida Keys, where the Atlantic meets Florida Bay and the Gulf of Mexico, at Marathon, FL. The station here is a subordinate tide prediction point. NOAA has no gauge in the water at this spot; its times and heights are published as offsets from a reference gauge, named below. The closest gauge measuring live water level is Vaca Key, USCG Station, Florida Bay (NOAA 8723970), 0.5 mi away, and high and low water here run on average about 220 min earlier than there. The nearest weather station is Vaca Key, FL, a shore station reporting wind and, at most sites, water temperature, 0.5 mi away.
The tide at Boot Key Harbor bridge, Boot Key
Boot Key Harbor bridge, Boot Key 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 1.9 ft, and 1.5 ft between the average high and the average low, a small tide. On an average day the higher high tops the lower high by 0.2 ft and the lower low sits 0.2 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.
About this station
- High tide reaches Boot Key Harbor bridge, Boot Key about 1.7 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
- NOAA predicts tides here from Key West, station 8724580. High tide comes about 63 min earlier and low tide about 37 min earlier than there.
- High tide heights run about 1.13 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 Boot Key Harbor bridge, Boot Key from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 1.9 ft above it and mean sea level 1.0 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 1.9 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 Key West, FL gauge. Source: NOAA CO-OPS station 8723971, 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.
