Long Sands seasonal overview
Best Surf Season (October - March)
The North Atlantic roars to life from October through March, delivering the most consistent and powerful swell to Long Sands. Average wave heights hover between 1.2m and 1.3m, with periods often in the 7.5-7.8s range – punchy and rideable, with plenty of storm-driven pulses pushing through. The wind regime plays heavily in our favor during these months, with dominant flow from the WSW and W blowing directly offshore across the EN-E facing beach. This is prime time – expect clean conditions on the best days thanks to ideal offshore winds blowing 29-37% of the time, funneling in long, grindy lines off the North Sea fetch.
Fair Surf Season (April & September)
Spring and early autumn deliver a mixed bag with average swell heights of 1.0m (April) and 0.9m (September) and periods around 7.3s and 6.7s. The North Atlantic storm track begins to weaken, but occasional pulses still sneak through, especially in September when the hurricane-tinged leftovers can add a bit of life. Offshore-friendly winds – WSW and W – are still present roughly 25-30% of the time, though wind directions become more variable. You’ll find sessionable waves, but consistency drops and you’ll need to pick your windows carefully – a solid mid-range SW to W breeze can make all the difference.
Low Surf Season (May - August)
Summer settles in with a whimper at Long Sands. Average wave heights plummet to 0.7-0.9m and periods drop into the 5.9-6.7s range – small, choppy, and often frustrating for anything but a log. The predominant swell shifts to shorter, locally generated windswell from the NNE, a direction that’s actually good for our spot, but the lack of consistent energy from the Atlantic leaves most days in the knee-to-waist fun-size range. Offshore wind frequencies also dip to 22-26%, making clean waves a rare treat. With the long summer days, you can still find a wave if you’re patient – but don’t expect to score anything epic.

Conditions at Long Sands in August
August: Bottom of the Barrel
August remains in the doldrums with an average swell of 0.7m and period of 6.0s. Swell direction is again NNE (20.9%) dominated, but wave heights rarely exceed 1m. The wind regime offers a slight improvement in ideal conditions at 26%, with W (13.6%) and WSW (13.3%) blowing offshore. However, the lack of swell energy means clean glassy days often yield just tiny dribblers. The occasional remnant tropical system or early autumn front can bump up the size, but it’s rare. For the dedicated, it’s a month of patience – focus on the first signs of an Atlantic low pressure deepening.
