About this station
NOAA builds the predictions for Cornfield Harbor, Md. from the WASHINGTON, Washington Channel, D.C. station: high tides about 0.48× the height, 376 min earlier; low tides about 0.53× the height, 455 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.
