About Pennsylvania tides

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.

Pennsylvania has 13 NOAA tide stations — 5 reference stations whose predictions come from harmonic analysis of observations there, and 8 subordinate stations calculated from them. The biggest tidal range in the state is at Newbold, Pa. — 8.4 ft between mean higher high water and mean lower low water.
