Harding Beach is a scenic sandy stretch located in Chatham, Massachusetts, on the elbow of Cape Cod, facing nearly due north into Nantucket Sound. The break here is typically gentle and rolling, as the sound buffers large open-ocean swells, making it best suited for beginners and longboarders looking for mellow, forgiving waves. Fall months bring the most consistent rideable surf as nor'easters push energy into the sound, giving this sheltered spot its best windows of action.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
