Fortress is a lesser-known surf spot tucked along the eastern tip of New York near Montauk, facing NNW toward Block Island Sound and exposed to swells wrapping around from the Atlantic. The break picks up energy from northeast and south swells that refract around the point, producing punchy, hollow beach break waves that reward surfers willing to make the trek. Its relative remoteness keeps crowds thin, making it a prized find for New York surfers seeking uncrowded conditions during the fall swell season.
