About this station
NOAA builds the predictions for Threemile Harbor entrance, Gardiners Bay from the NEW LONDON, State Pier station: high tides about 0.96× the height, 39 min later; low tides about the same height, 19 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.
