Capbreton seasonal overview

Best Surf Season (October - March)

The North Atlantic spins up a relentless procession of deep low-pressure systems during these months, sending consistent, powerful swell trains toward the Landes coast. With average wave heights hovering between 1.6 and 1.8 m and periods frequently reaching into the 12–13 second range, Capbreton receives a steady diet of pumping, heavy surf ideal for the region's sandbar peaks. Offshore winds from the east and southeast are most common during these months, blowing clean across the WNW-facing beach and grooming the faces. Ideal wind frequencies range from 30% in March up to 39% in December, meaning plenty of sessions with clean, lined-up waves. This is prime time to score classic Capbreton barrels and long, rippable walls.

Fair Surf Season (April & September)

As the seasons transition, the Atlantic storm track begins to shift, and the swell intensity backs off. April sees an average height of 1.2 m with an 11-second period – still enough for fun, solid waves when a fetch aligns properly. Ideal wind drops to 25%, and the springtime sea breeze often kicks in by midday. September marks the beginning of the autumn ramp-up, with average height creeping back to 1.1 m and period lengthening to 10.6 s. The chance of a clean east wind increases to 27%, offering occasional vintage sessions before the true winter machine fires up. Both months can deliver good, rippable conditions, but consistency and power are not yet at their peak.

Low Surf Season (May - August)

From late spring through summer, the Atlantic's fury takes a vacation. The Azores High dominates, blocking major storms and allowing only weak, short-period NW windswell to filter through. Average wave heights drop to a mere 0.9–1.0 m with periods around 9–10 seconds – typically small, fun-sized, groveling conditions. Offshore wind frequencies fall to 15–20%, and the prevailing onshore westerlies often chop up the surf. While the rare east wind event can produce clean little waves for a grovel board, this is the off-season for serious wave riding. The odd distant hurricane swell might sneak in, but overall expect micro to small waves and a lot of flat spells.

Conditions at Capbreton in September

September: Autumn Awakens

September is a transitional month where the surf starts to pick up. Average height rises to 1.1 m and period to 10.6 s – back into fun, good, solid territory. The swell mix widens: NW at 53.8% and WNW at 33.3%, with more energy in the 1–2 m range. Ideal wind frequency increases to 27%, and the wind distribution shows a healthier east component (E 6.8%, ESE 5.7%, SE 3.5%). The westerly winds are still present but less dominant. Early autumn storms begin to develop, generating long-period swells that can deliver pumping sessions when conditions align. The water is still warm from summer, making for pleasant sessions. September offers the best trade-off between decent waves and comfortable weather. Keep an eye on the Atlantic basin – the first big swell of the season could arrive any day.
