Cahoon Hollow Beach is one of the premier surf spots on the Outer Cape in massachusetts, sitting along the exposed Atlantic-facing shoreline of Wellfleet where powerful open-ocean swells arrive with little obstruction. The beach faces WSW into the ocean through its transect, but the broad east-facing coastline funnels northeast and east swells into punchy, fast-breaking beach break peaks that can deliver solid barrels on the right sandbar setups. Fall is the prime season when hurricane swells and nor'easters push quality surf, drawing experienced riders from across the New England region.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Cahoon Hollow Beach is 5-7ft with a 9.65s swell period. Wind is SW at 12mph and conditions are rated Very Good. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Cahoon Hollow Beach is 5-7ft, produced by a 3.8ft E primary swell at 10s, a 0.9ft W wind swell swell at 2s. Breaking wave height is the actual rideable wave size at the shore — calculated from offshore swell data using this spot's coastal bathymetry — not the raw buoy reading.
