About this station
NOAA builds the predictions for Cat Island from the SOUTH PASS station: high tides about 1.23× the height, 133 min later; low tides about 1.23× the height, 120 min later.
The northern Gulf runs small, mostly diurnal tides — often just one high and one low a day — where wind and river flow routinely outvote the moon.
