About this station
NOAA builds the predictions for Edgewater, South River from the Baltimore, Fort McHenry station: high tides about 0.81× the height, 111 min earlier; low tides about 0.91× the height, 127 min earlier.
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.
