π Local Knowledge
Green Harbor in Massachusetts is a sheltered beach and jetty break that only works occasionally, with summer often bringing flat conditions. It favors northeast swells paired with offshore winds from the same direction and produces mostly left-hand waves, best around mid tide. The spot can draw crowds when it's breaking and has strong rips that require caution. Spring is the most reliable season for clean, rideable surf, with March offering the best conditions.
