Where North Harris Channel is
North Harris Channel sits at 24.6533° N, 81.5533° W on the Florida Keys, where the Atlantic meets Florida Bay and the Gulf of Mexico, about 2 mi southwest of Cudjoe Key, 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 Key West (NOAA 8724580), 17.4 mi away, and high and low water here run on average about 19 min later than there. The nearest weather station is Key West Naval Air Station, an airport reporting wind, visibility and sky cover, but no water temperature, 9.6 mi away.
The tide at North Harris Channel
North Harris Channel 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. 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
- NOAA predicts tides here from Key West, station 8724580. High tide comes about 332 min later and low tide about 484 min later than there.
- High tide heights run about 0.25 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 publishes no datums for this point. Its predictions are offsets from Key West and are referenced to MLLW there. Source: NOAA CO-OPS station 8724367, 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.
