The tide at Main Key, Barnes Sound
Main Key, Barnes Sound 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.

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 Government Cut, Miami Harbor Entrance and are referenced to MLLW there. Source: NOAA CO-OPS station 8723571. 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.
