About this station
Sievers Cove, Goat Island is one of NOAA's reference tide stations — its predictions are computed directly from harmonic analysis of water levels observed here, and other nearby stations are calculated from it.
Texas tides are small and mostly diurnal, and the bays answer wind and season more than the moon. A strong norther can drain a flat in an afternoon.
