About this station
NOAA builds the predictions for Sharkfin Shoal Light from the CHESAPEAKE BAY BRIDGE TUNNEL station: high tides about 0.86× the height, 346 min later; low tides about 0.92× the height, 366 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.
