About the tides at St. Louis Bay entrance

Tides at St. Louis Bay entrance are mostly diurnal: one rise and one fall a day, with a slow change between them. The mean range is small, about 1.5 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 1.8 ft. The next spring tides peak on Saturday, with a range of 2.4 ft. Neap tides follow on October 8, when the range shrinks to 0.4 ft.

St. Louis Bay entrance is a NOAA water level station with a live gauge, updated every 6 minutes. Predictions come from the station's own tide records. It also reports water temperature, wind and air pressure. It was established in 1978. The nearest other station is Waveland, 4 mi away, where high tide comes about 8 min earlier.
