Middles - surf spot statistics

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.

February: Winter’s Last Stand

February mirrors January closely: 1.9m average swell height, 9.7s period, and a swell distribution that still heavily favors east-northeast (41.6%) but retains a healthy 40.7% from the north quadrant. The wind, however, remains stubbornly out of the east (31.7%) and east-northeast (35.1%), giving an onshore chop that only the most sheltered pockets survive. Ideal wind percentages tick up slightly to 19%, and the frequency of south-southwest wind days (1.0% of the time) is still low, but the few days it does clock around — often in the wake of a cold front — can deliver 2-2.5m, long-period swell with sideshore texture that peels perfectly along the sandbar. Keep an eye on the 500mb trough position: a deep trough off the Mid-Atlantic puts Middles in the sweet spot for northerly swell trains.
