Madaket sits on the western tip of Nantucket in massachusetts, offering a raw and exposed stretch of sandy beach that picks up southwest and northwest swells with surprising consistency. The break benefits from its open Atlantic exposure and the funneling effect of Nantucket Sound, producing punchy, hollow peaks that reward surfers willing to make the trek out to this remote corner of the island. Fall is the prime season when hurricane swells and nor'easters deliver the most powerful and well-shaped waves, often with minimal crowds.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Madaket is 1ft with a 3.8s swell period. Wind is WSW at 14mph and conditions are rated Very Poor. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Madaket is 1ft, produced by a 1.3ft SSE primary swell at 7s, a 2.5ft SW wind swell swell at 4s. 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 Madaket is Thursday from 6 AM to 9 AM with 2ft waves, a 7.95s swell period, and conditions rated Fair. Check the hourly forecast for updates as conditions can shift.
