Nantasket Beach is Boston's go-to surf spot—the closest consistent wave to a city of millions, accessible from downtown in under an hour. The northeast-facing beach catches nor'easter swells that miss south-facing breaks, providing an alternative window when the rest of New England goes flat. The water is cold year-round, the crowd is dedicated, and the rocky areas demand awareness, but Nantasket delivers surf to a metropolitan area that has no business having a surf scene. For Bostonians who refuse to let geography dictate their stoke, Nantasket is home.

Frequently Asked Questions

What kind of wave is Nantasket Beach?
