About this station
NOAA builds the predictions for Michoud Substation, ICWW from the SOUTH PASS station: high tides about 1.09× the height, 397 min later; low tides about 1.09× the height, 382 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.
