Local Knowledge & Surf Guide

Robert Moses in Long Island, NY, is an exposed beach break with reliable surf year-round. It receives a mix of groundswells and windswells, with the ideal swell direction from the southeast. Offshore winds from the north-northwest create the best conditions, especially when combined with a south-southeast swell. The break offers both left and right-hand waves and works well at all tide stages. Summer, particularly September, sees the most consistent clean waves. The spot can get crowded when the surf is up, and strong rips require caution.
