Manasquan Inlet • Surf Spot Statistics

Best Surf Season (October - March)

The New Jersey coast, and Manasquan Inlet in particular, is fundamentally a late-fall-through-winter setup. As the North Atlantic storm track intensifies, strong extratropical cyclones and nor'easters generate a steady supply of east and southeast swell. The average surf clocks in around 4ft (1.2-1.3m) with periods in the 7-8s range, and while that mix is often short-period windswell, the arrival of a low-pressure system off the Mid-Atlantic coast can bring 10-14s groundswell. What makes this stretch special is the wind: cold fronts sweeping off the continent leave behind west, west-southwest and northwest winds, blowing offshore at this east-facing beach. That combination gives Manasquan a much cleaner, more organized wave than the raw storm surf suggests. The NAO's negative phase often correlates with strong northeast-blocking patterns and a more active storm track along the Eastern Seaboard, which is exactly what the inlet wants.

Fair Surf Season (April - May, September)

As the ocean warms, the wave machine changes character. April and May see a shift toward south, southeast and east windswell, with average heights easing to 3-4ft (1.0-1.2m). The wind is less reliable: southwest and south winds take over, so you need to pick the windows. September is the wild card; tropical storms and early-autumn nor'easters bring a bump in average period to 8.3s and more ESE/SE groundswell, but the wind is split between continued southwest flow and developing northwest flow. When the tropics align and the wind goes west, September can produce memorable waves.

Low Surf Season (June - August)

Summer is the slow season at Manasquan Inlet. The average swell drops to 2-3ft (0.8-0.9m), dominated by locally generated south and southeast windswell with periods around 7s. The same south/southwest sea breeze that keeps the beaches crowded usually adds onshore junk. Morning light wind and the occasional tropical swell are the only saving graces. If a named storm pushes through the Bahamas, the inlet can light up even in August, but on a climatological basis these are the months to save your energy.
