Where Carysfort Reef is
Carysfort Reef sits at 25.2217° N, 80.2117° W on the Florida Keys, where the Atlantic meets Florida Bay and the Gulf of Mexico, about 6 mi east of North Key Largo, 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 Virginia Key, Biscayne Bay (NOAA 8723214), 35.4 mi away, and high and low water here run on average about 4 min earlier than there. The nearest weather station is Key Largo, an airport reporting wind, visibility and sky cover, but no water temperature, 7.9 mi away.
The tide at Carysfort Reef
Carysfort Reef 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 2.5 ft, and 2.3 ft between the average high and the average low, a moderate tide. On an average day the higher high tops the lower high by 0.1 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 Carysfort Reef about 1.5 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 Government Cut, Miami Harbor Entrance, station 8723178. High tide comes about 19 min later and low tide about 39 min later than there.
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 Carysfort Reef from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 2.6 ft above it and mean sea level 1.3 ft. These datums are controlled from NOAA's Miami Beach, FL gauge. Source: NOAA CO-OPS station 8723583, established 1975, gauge removed 1991. 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.

TidalMapMonthly tide calendar
🌊 Biggest flood tides at Carysfort Reef this month: Oct 8, Oct 9, Oct 10, Oct 11, Oct 12, Oct 25, Oct 26, Oct 27, Oct 28, Oct 29. These spring highs push water up into the grass and over the oyster rock; prime for poling into flooded marsh for tailing reds.
🔻 Negative (minus) low tides at Carysfort Reef this month: Oct 27, Oct 28. These drain the flats and expose the oyster rock, prime for sight-fishing and clamming.
Best fishing times (solunar)
Major and minor solunar windows for Carysfort Reef, peak feeding activity is around the moon overhead/underfoot (majors) and moonrise/moonset (minors). Score is the day's activity coefficient (0–100).
