About this station
NOAA builds the predictions for Oyster Bay Harbor from the BRIDGEPORT station: high tides about 1.08× the height, 7 min later; low tides about 1.08× the height, 13 min later.
Barrier islands, big bays, and river tides: Chesapeake and Delaware bays carry the tide deep inland, and a nor'easter can hold water in, or blow it out, for days at a time.
