Cisco Beach is a beloved surf spot on the south shore of Nantucket Island in massachusetts, offering consistent south and southwest swells that roll across open Atlantic fetch before wrapping into this exposed stretch of coastline. The sandy bottom produces punchy, hollow beach break waves that can deliver quality peaks, especially during fall hurricane season when powerful groundswells light up the lineup. Its remote island location keeps crowds manageable compared to mainland massachusetts spots, and the wide beach gives surfers room to spread out and find their own peak.
