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 1-2ft with a 8.25s swell period. Wind is SSW at 12mph and conditions are rated Poor. The forecast updates hourly so you can plan your session around the cleanest windows.
