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 1-2ft with a 8.1s swell period. Wind is SSW at 13mph and conditions are rated Poor. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Cahoon Hollow Beach is 1-2ft, produced by a 2.4ft SE primary swell at 8s, a 1.2ft E secondary swell at 9s, a 0.3ft ESE tertiary swell at 13s, a 0.9ft SSW 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.
Based on the current 5-day forecast, the best window to surf Cahoon Hollow Beach is Friday from 11 AM to 2 PM with 3ft waves, a 8.6s swell period, and conditions rated Fair. Check the hourly forecast for updates as conditions can shift.
