Best Surf Season (October - March)

The North Atlantic kicks into high gear from October through March, delivering the most consistent north-northeast swell to this north-facing beach. Average swell heights hover around 1.8-1.9m with periods frequently in the 9-10s range, offering powerful, long-period waves that can truly light up when the wind aligns. The real challenge? The dominant wind regime during these months is out of the east-northeast—a direct onshore flow that chops up the face. However, when a cold front sweeps through and winds clock to the southwest, the ocean grooms the lines into clean, orderly peaks. The ideal window is narrow (wind is perfect only 15-22% of the time), but the payoff is epic: thick, hollow walls that rewind the clock to classic point-break perfection.

Fair Surf Season (April, May, September)

As the jet stream retreats northward, the average swell height drops to 1.3-1.6m and periods settle into the 8-9s range. This is transitional territory. April and May see a significant uptick in offshore southerly wind days (ideal conditions reach 25-31%), which can turn even modest east-northeast swell into clean, rippable lines. The trade-off is that the north-northeast component of the swell becomes less frequent, so wave quality becomes more dependent on local sea breeze cycles rather than open-ocean storms. September offers a similar story: a late-summer spike in southerly wind frequency (30% ideal) coincides with the first north swells of autumn, making for a sneaky-good shoulder season where crowds thin and the ocean starts to wake up.

Low Surf Season (June - August)

Summer trades on the US East Coast are relentless. From June through August, the dominant wind howls out of the east-northeast more than 80% of the time, delivering a steady onshore flow that leaves Middles choppy, sectiony, and frustrating. Average wave heights drop to 1.3-1.4m and periods bottom out around 7-7.4s — short-period, wind-swell slop that struggles to organize on a north-facing beach. The swell direction is almost exclusively east to east-northeast (over 90% combined), which means waves approach at an oblique angle, offering only weak, closeout reformations. Offshore wind from the south is a rare event (13-18% of the time), and when it does arrive, it often comes with tiny, groveling conditions. This is the season to check in occasionally for a surprised glassy day, but the odds are stacked against you.

August: Late Summer Lull

August brings a slight uptick from July’s lows, but conditions remain marginal. Average swell height is 1.3m with a period of 7.4s. The swell direction is nearly identical to July: east-northeast (57.7%) and east (35.9%) dominate, with only a tiny 4.8% from the north quadrant. Wind is still predominantly onshore from the east (42.2%) and east-northeast (36.6%). Ideal south wind ticks up to 18%, offering occasional morning glass-offs, but the waves are rarely more than 0.5-1.5m and lack the period to hold a steep face. Subtropical storms can bring a pulse of energy, but the troughs come and go quickly. For the local surfer, August is about patience — and maybe a few dawn patrol seshes when the forecast hints at a front wrapping in south wind and a distant north-northeast groundswell.
