Nantucket, Massachusetts offers surprisingly rideable surf along its south-facing shores, picking up south and southeast swells generated by Atlantic storms and passing hurricanes. The sandy bottom breaks produce punchy, inconsistent waves that reward patient surfers willing to wait for the right conditions, particularly during fall when powerful nor'easters and late-season hurricanes send quality groundswell through. The island's remote location off the coast of Massachusetts means crowds are rarely an issue, giving surfers plenty of room to explore its various beach breaks in relative solitude.
