The barrier beach stretches east from Edgartown in a long, blonde ribbon separating Katama Bay from the Atlantic. You'll feel the difference the moment you crest the dunes: wind whips harder here, waves thunder louder, and the horizon holds nothing but gray-green water meeting sky. This is not the placid harbor swimming of Edgartown proper. South Beach means serious ocean.

Surfers claim the western end near the parking area, reading sets that roll in from hurricanes spinning hundreds of miles offshore. On big swell days you'll see shortboarders carving shoulder-high waves while bodyboarders tuck into shorebreak barrels. Families spread blankets farther east where the beach widens, though even here the waves demand attention—lifeguards went off-duty decades ago, and riptide warnings get posted on weathered wooden signs.
Come September, after the August crowds thin, you'll have whole stretches to yourself. Piping plovers reclaim their nesting territory. Striped bass fishermen wade into the surf at dawn. The beach plums behind the dunes darken to purple, and if you time it right on an autumn afternoon, you'll watch the sun drop into Katama Bay behind you while the Atlantic crashes steady and cold at your feet.
