Mastic Beach is a sandy beach break on Long Island's South Shore that picks up swell from northeastern and northwesterly directions, making it a reliable option during autumn swells and nor'easters. The beach offers forgiving sand bottom conditions ideal for progression, with mellow rolling waves that peel across the sandy seafloor. Located in a quieter residential area, this spot provides a more relaxed atmosphere compared to the busier Atlantic-facing beaches in the region.
