About this station
NOAA builds the predictions for Shell Island from the GALVESTON, Galveston Channel station: high tides about 1.07× the height, 54 min later; low tides about 1.07× the height, 39 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.
