Where Key West is
Key West sits at 24.5557° N, 81.8079° W on the Florida Keys, where the Atlantic meets Florida Bay and the Gulf of Mexico, at Key West, FL, in Mainland Monroe County. The station here is a live gauge in NOAA's National Water Level Observation Network, the reference network the rest of the coast's tide predictions are tied to. It has been in NOAA's records since 1913. The nearest weather station is Key West, FL, a shore station reporting wind and, at most sites, water temperature, right at this station.
The tide at Key West
Key West has a mixed tide: two highs and two lows a day, but of unequal size, so one low each day drains a little lower than the other. This month's predictions average 1.9 high tides a day here. The mean range from lower low to higher high is 1.8 ft, and 1.3 ft between the average high and the average low, a small tide. On an average day the higher high tops the lower high by 0.3 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 Key West about 2.8 hours after the moon passes overhead. That lag is local, which is why high water does not line up with the moon.
- Highest water on record: 4.9 ft on Oct 24, 2005.
- Lowest on record: -1.7 ft on Feb 19, 1928.
- The National Weather Service counts 2.9 ft as minor flooding here, 3.4 ft as moderate and 3.9 ft as major.
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 Key West from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 1.8 ft above it and mean sea level 0.9 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 1.8 ft above MLLW here, so a water level on this page converts to NAVD88 by subtracting that amount. Source: NOAA CO-OPS station 8724580, a National Water Level Observation Network gauge, established 1913. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them. The observed line is the gauge's own six-minute water level feed.

🌊 Biggest flood tides at Key West this month: Oct 1, Oct 2, Oct 10, Oct 11, Oct 12, Oct 25, Oct 26, Oct 27, Oct 28, Oct 30, Oct 31. 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 Key West 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 Key West, peak feeding activity is around the moon overhead/underfoot (majors) and moonrise/moonset (minors). Score is the day's activity coefficient (0–100).
