Delaware Bay - Lewes, Delaware
NOAA Tidal Predictions for the Delaware River & Bay

---

The National Oceanic and Atmospheric Administration (NOAA)
has three "reference station" locations in the tidal Delaware River and Bay with full daily tidal predictions:

Breakwater Harbor, Delaware

Reedy Point, Delaware

Philadelphia, Pennsylvania

Tidal predictions for more than 3,000 other nationwide locations, referred to as "subordinate stations," are obtained by applying specific differences to the daily tidal predictions for one of the reference stations. Here are links to NOAA's subordinate stations located throughout the tidal Delaware River and Delaware Bay:

Delaware Bay, Western Shore

Delaware Bay, Eastern Shore

Liston Point to Reedy Point

Chesapeake-Delaware Canal to Auburn (Oldmans Creek)

Marcus Hook to Philadelphia

Palmyra (Pennsauken Creek) to Trenton
