Spessard Holland seasonal overview
Best Surf Season (November - March)
The winter months deliver the most consistent and quality surf at Spessard Holland. As the Atlantic storm track shifts southward, a steady procession of extratropical cyclones spins up deep low-pressure systems, firing long-period swell from the optimal NNE through E window. Combined with a higher frequency of offshore winds from the SSW-WSW quadrant, these months offer the best chance of clean, punchy waves in the fun to good size range (0.5-1.5m). November stands out with the highest average swell height (1.0m) and a period often stretching into the 8-9 second range, providing plenty of push.
Fair Surf Season (April, May, September, October)
Transitional months see a decline in both swell size and wind consistency. Spring (April-May) brings a gradual weakening of the North Atlantic storm machine, with average heights dropping to 0.7-0.8m. While occasional cold fronts can still deliver decent ENE to E swell, the percentage of offshore wind drops below 20%, making clean sessions harder to come by. Autumn (September-October) sees a resurgence: September averages 0.8m with a respectable 9.0s period, and October ramps up to 0.9m as the first autumn storms organize. However, the wind remains fickle, with ideal conditions only around 14-16% of the time. Expect mixed bag days with onshore seabreezes often ruining the afternoon session.
Low Surf Season (June - August)
The summer doldrums hit Spessard Holland hard. From June through August, the average swell height plummets to 0.5-0.6m, and periods hover around 7.6-8.1 seconds. The dominant swell direction becomes overwhelmingly east to southeast (E and ESE account for over 60% of swells), which, while in the window, often arrives with weak, windswell-like energy. More critically, the region comes under the influence of persistent high pressure, driving a relentless easterly trade wind flow that is directly onshore for this east-facing beach. Offshore wind percentages drop to 11-14%, making any rideable wave a rare treat. Expect mostly small, groveling conditions unless a tropical system or distant hurricane swell lines up – a low-probability event.

Conditions at Spessard Holland in September
September: Autumn Awakening
September heralds the start of the transition back to quality surf. Average swell height jumps to 0.8m and the period stretches to 9.0s – the highest of the year. Swell direction becomes more northerly: ENE (35.6%) and E (37.5%) remain key, but NE swell rebounds to 13.3% and even NNE (1.9%) appears. The extended period signals more powerful groundswell from developing mid-latitude storms. Unfortunately, ideal wind is still low at 16%, and onshore easterly winds (NE, ENE, E) are frequent. However, September also sees a higher chance of tropical systems that can deliver clean, long-period E swell with light westerly winds in their wake. Expect a mix: plenty of blown-out days, but also some pumping sessions when the synoptic setup aligns.
