About the tides at Southwest Pass

Southwest Pass usually gets one high and one low tide a day, known as a diurnal tide. The pattern follows the reference station at South Pass. The mean range is small, about 1.4 ft, so wind and pressure can matter as much as the tide itself. The next spring tides peak on October 29, with a range of 2.4 ft. Neap tides follow on Friday, when the range shrinks to 0.3 ft. In the next 12 months the highest predicted tide here is 2.3 ft on October 29, and the lowest is −1.2 ft on January 20.

Southwest Pass is a subordinate station. NOAA predicts its tides by adjusting South Pass: highs come about 35 min later and lows about 13 min earlier than there. The nearest other station is SW Pass, 0.8 mi away, where high tide comes about 40 min earlier.

Predictions are based on South Pass.
