About this station
Portsmouth, Naval Shipyard 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.
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.
