Where Horn Island, Mississippi Sound is
Horn Island, Mississippi Sound sits at 30.2383° N, 88.6667° W on the northern Gulf of Mexico, about 7 mi southwest of Pascagoula, MS. The station here is a historical NOAA reference station: a gauge measured the tide at this spot from 1980 until 2005, and NOAA still publishes harmonic predictions from that record. There is no live reading here today. The closest gauge measuring live water level is Pascagoula NOAA Lab (NOAA 8741533), 10.9 mi away, and high and low water here run on average about 5 min earlier than there. The nearest weather station is Petit Bois Island, Port of Pascagoula, MS, a shore station reporting wind and, at most sites, water temperature, 9.8 mi away.
The tide at Horn Island, Mississippi Sound
Horn Island, 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 1.6 ft, and 1.4 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 Horn Island, Mississippi Sound from the 1983-2001 National Tidal Datum Epoch; mean higher high water is 1.6 ft above it and mean sea level 0.8 ft. These datums are controlled from NOAA's Pensacola, FL gauge. Source: NOAA CO-OPS station 8742221, established 1980, gauge removed 2005. The tide times and heights are NOAA's official harmonic predictions for this station; TidalMap republishes them daily and does not alter them.
