About this station
NOAA builds the predictions for South Point, Marsh Island from the GALVESTON, Galveston Channel station: high tides about 1.30× the height, 19 min earlier; low tides about 1.30× the height, 117 min earlier.
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.
