Martinique - surf spot statistics

Best Surf Season (October - March)

The North Atlantic winter pattern delivers consistent, powerful S-SSE swell to Martinique's south-facing shores. When a strong high-pressure system settles over Quebec or the Gulf of St. Lawrence, it funnels cold northerly winds (N, NNW, NW) across Nova Scotia, creating clean, offshore conditions. These are the days to watch: long-period swell from distant Atlantic storms wrapping into the bay, groomed by a crisp offshore breeze. Average wave heights hover around 1.6-1.7m with periods of 8.6-8.7s, offering plenty of punch. However, the offshore wind window is narrow and often fleeting, so timing is everything. The cold water and air temperatures add an extra layer of commitment, but the reward is quality surf when it all comes together.

Fair Surf Season (April, September)

Transition months bring a mix of fading winter energy and building autumn patterns. April sees lingering swell from SSW and S directions (over 36% combined) with average heights dropping to 1.4m and periods to 8.4s. The wind regime becomes more variable, with offshore winds from the north occurring about 34% of the time. September marks the first stirrings of the autumn storm track: average swell height climbs back to 1.2m, periods lengthen to 8.5s, and the ideal wind frequency jumps to 39%. Both months offer intermittent windows of clean, fun-sized waves, but consistency is lacking. For the patient surfer, these shoulder months can yield surprisingly good sessions without the winter crowds.

Low Surf Season (May - August)

Summer at Martinique is dominated by weak, short-period S-SSE windswell generated by local sea breezes and tropical systems passing far to the south. Average wave heights bottom out at 1.0-1.2m, and periods drop to 7.2-7.7s, resulting in small, choppy, and often messy conditions. Onshore winds from the south and southwest prevail, with the ideal wind frequency falling to just 29-33%. Days with surfable waves are rare, and when they do occur, they are typically small and grovelly. This is the low season for a reason; unless you are desperate for a session or have a longboard, the summer months are best spent exploring other activities or waiting for the autumn return of the North Atlantic swell machine.

September: Autumn Stirrings

September marks the beginning of the transition back to winter. The average swell height climbs to 1.2m, and the period extends to 8.5s, indicating the return of better-quality, longer-period swell. The swell direction remains southerly – S (19.0%), SSW (18.6%), and SSE (17.4%) – but the increased period means these waves have more power and shape. The wind patterns become more favorable, with the ideal offshore wind frequency jumping to 39% – the highest since March. Strong northwesterly winds (WNW, NW, NNW) blow 15.2% of the time, often associated with early autumn cold fronts. These setups can produce clean, punchy waves in the fun-sized range. September is a promising month for those looking to beat the winter crowds.
