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.
