Where Mayport Naval Station, Water Treatment Dock is
Mayport Naval Station, Water Treatment Dock sits at 30.4000° N, 81.4133° W on Florida's Atlantic coast, at Jacksonville, FL. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1995 until 2008, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Mayport (Bar Pilot Dock) (NOAA 8720218), 0.9 mi away, and high and low water here run on average about 12 min earlier than there.
The tide at Mayport Naval Station, Water Treatment Dock
Mayport Naval Station, Water Treatment Dock 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 5.1 ft, and 4.7 ft between the average high and the average low, a moderate tide. On an average day the higher high tops the lower high by 0.3 ft and the lower low sits 0.2 ft below the other low. 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 Mayport Naval Station, Water Treatment Dock about 1.0 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: 7.8 ft on Sep 27, 2004.
- Lowest on record: -1.9 ft on Mar 8, 2005.
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 Mayport Naval Station, Water Treatment Dock from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 5.1 ft above it and mean sea level 2.5 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 3.1 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 (Bar Pilots Dock), FL gauge. Source: NOAA CO-OPS station 8720211, established 1995, gauge removed 2008. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
