About the tides at Horn Island

Horn Island usually gets one high and one low tide a day, known as a diurnal tide. The mean range is small, about 1.4 ft, so wind and pressure can matter as much as the tide itself. From the average lower low to the average higher high, the difference is 1.6 ft. The next spring tides peak on Friday, with a range of 2.4 ft. Neap tides follow on October 8, when the range shrinks to 0.4 ft.

This is a prediction station. NOAA calculates its tides from past measurements at this spot, but there is no live gauge today. NOAA measured the tide here from 1980 to 2005 to set up these predictions. The nearest other station is Graveline Bayou Entrance, 9 mi away. For tidal currents, see Horn Island, Petit Bois Island, between.
