About this station
NOAA builds the predictions for New Castle, Delaware from the REEDY POINT station: high tides about the same height, 29 min later; low tides about the same height, 40 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.
