Coopers Beach in Southampton, New York is a mellow beach break on the South Fork of Long Island, facing northwest into Peconic Bay and the Great Peconic waters, which means it picks up wind swell and chop rather than classic open-ocean groundswell. The waves here are typically small and soft, making it a friendly spot for beginners and longboarders looking to practice in less crowded conditions than the more exposed Atlantic-facing beaches nearby. Its sheltered orientation and sandy bottom create forgiving, rolling waves that are best enjoyed during strong northwest storm fetch events in fall and winter.
