Where Ortega River entrance is
Ortega River entrance sits at 30.2783° N, 81.7050° W on Florida's Atlantic coast, at Jacksonville, FL, in Duval County. 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 Jacksonville, Main Street Bridge (NOAA 8720226), 4.0 mi away, and high and low water here run on average about 46 min later than there. The nearest weather station is Jacksonville Naval Air Station, an airport reporting wind, visibility and sky cover, but no water temperature, 3.5 mi away.
The tide at Ortega River entrance
Ortega River entrance 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 1.2 ft, and 1.1 ft between the average high and the average low, a small tide. For the water around it: Florida's Atlantic tides are semidiurnal, two highs and two lows a day, with ranges of 2 to 5 ft that shrink inside the lagoons.
About this station
- High tide reaches Ortega River entrance about 3.3 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 Mayport (Bar Pilot Dock), station 8720218. High tide comes about 129 min later and low tide about 167 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 fixes MLLW at Ortega River entrance from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 1.2 ft above it and mean sea level 0.6 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 0.6 ft above MLLW here, so a water level on this page converts to NAVD88 by subtracting that amount. These datums are controlled from NOAA's Mayport (Ferry Depot), FL gauge. Source: NOAA CO-OPS station 8720296, established 1978, gauge removed 1979. 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.
