Marconi Beach is a stunning stretch of Atlantic-facing shoreline on the Outer Cape in massachusetts, nestled within the Cape Cod National Seashore near Wellfleet. Facing WSW into the Atlantic, this beach picks up northeast and east swells that wrap around the Cape's elbow, producing punchy, fast-breaking beach break waves on a sandy bottom. The dramatic eroding bluffs and remote setting make it one of the more scenic and uncrowded surf destinations in massachusetts, especially rewarding during fall when powerful nor'easters push consistent groundswell.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Marconi Beach is 5-7ft with a 9.65s swell period. Wind is WSW at 11mph 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 Marconi Beach is 5-7ft, produced by a 2.5ft E primary swell at 10s, a 0.5ft 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.
