Manasquan Inlet - surf spot statistics

Manasquan Inlet is a surf spot largely dominated by wind swells, with ground swells being relatively rare. The best months for surfing here are typically late summer and early fall, specifically from **August to October**, when ground swell activity increases slightly and wind conditions improve marginally. September stands out with 20% ground swell occurrence—the highest of the year—alongside reduced no-swell days (19%) and a mean swell size of 0.8m, offering more consistent rideable waves. While wind conditions remain suboptimal (71% bad winds even in September), this period still provides the best balance between swell energy and surfable days. Winter and early spring (November to March) bring choppier conditions due to strong onshore winds (bad wind conditions exceeding 80%) and smaller, wind-driven swells. Summer months (May to July) see a drop in swell size (0.6-0.8m) and persistent bad wind conditions (70-73%), though June and July offer slightly better wind windows (30-31% favorable winds). Overall, surfers can expect the most reliable sessions in late summer and early fall, but must contend with generally poor wind alignment year-round. The spot favors those comfortable with wind swell surf, as clean conditions are rare.

Manasquan Inlet in June typically offers small to moderate surf conditions, with an average swell height of 0.7m and a decent period of 7.5s, providing some energy for rideable waves. The swell direction is predominantly from the ESE, SE, and SSE, with the highest frequency of waves in the 0.5-1.5m range. Specifically, ESE swells contribute the most, with 13.23% at 0-0.5m and 18.37% at 0.5-1m, followed by SSE swells, which account for 5.23% at 0-0.5m and 20.40% at 0.5-1m. Larger waves (1.5-2m) are rare, mostly from E and ESE directions. Wind conditions are favorable for surfing only 30% of the time, with the best scenario being light offshore or cross-offshore winds (typically from the W or NW directions). However, SW and SSW winds are more common, often blowing onshore at 10-20kph, which can create choppy conditions. Overall, June is a mixed month—small but rideable waves are frequent, though surfers will need patience for those cleaner, wind-friendly sessions. Expect mostly knee-to-waist-high waves with occasional chest-high sets when swell pulses align favorably.
