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 Virginia Key, Biscayne Bay (NOAA 8723214), 23.6 mi away, and high and low water here run on average about 32 min later than there. The nearest weather station is Key Largo, an airport reporting wind, visibility and sky cover, but no water temperature, 6.4 mi away.

The tide at Adams Key, south end, Biscayne Bay

Adams Key, south end, Biscayne Bay 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 1.6 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 0.0 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

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 Adams Key, south end, Biscayne Bay from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 1.6 ft above it and mean sea level 0.9 ft. These datums are controlled from NOAA's Key Colony Beach, FL gauge. Source: NOAA CO-OPS station 8723453, established 1974, gauge removed 1987. 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.
