About Martha's Vineyard Beach
Martha's Vineyard is a storied island south of Cape Cod, reached by ferry and known for its charming towns, colorful gingerbread cottages, and the dramatic clay Aquinnah Cliffs. Its beaches range from the surf of South Beach to calm, warm sound-side shores, making it a versatile island escape. The North Atlantic here is cold even in summer — typically the low-to-upper 60s°F at the August peak — and cold the rest of the year. Check the safety flag and rip-current risk above, be ready for cold water, and swim near a lifeguard.
