Where Gulfport Harbor, Mississippi Sound is
Gulfport Harbor, Mississippi Sound sits at 30.3600° N, 89.0817° W on the northern Gulf of Mexico, at Gulfport, MS. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1979 until 2011, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is St. Louis Bay entrance (NOAA 8747437), 14.7 mi away, and high and low water here run on average about 85 min earlier than there. The nearest weather station is Gulfport - Gulfport-Biloxi International Airport, an airport reporting wind, visibility and sky cover, but no water temperature, 3.6 mi away.
The tide at Gulfport Harbor, Mississippi Sound
Gulfport Harbor, Mississippi Sound has a diurnal tide: usually one high and one low a day, with the daily rhythm shifting about 50 minutes later each day and fading near the moon's equatorial crossing. This month's predictions average 1.1 high tides a day here. The mean range from lower low to higher high is 1.7 ft, and 1.5 ft between the average high and the average low, a small tide. On an average day the higher high tops the lower high by 0.1 ft and the lower low sits 0.1 ft below the other low. For the water around it: Northern Gulf tides are diurnal, one high and one low most days with ranges of 1 to 2 ft, so wind and river stage move the water as much as the moon.

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 Gulfport Harbor, Mississippi Sound from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 1.7 ft above it and mean sea level 0.9 ft. The land survey datum NAVD88, the zero on topographic maps and flood maps, is 0.7 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 Dauphin Island, AL gauge. Source: NOAA CO-OPS station 8745557, established 1979, gauge removed 2011. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
