Conditions at Capbreton in October
October: The North Atlantic Roars Back to Life
October is when Capbreton shifts from summer standby to true winter-strike mode. There is a sharp jump in average swell height to 4ft (1.3m) and the average period jumps to 11.3s, putting the system back into the powerful, long-period range. The swell direction remains in the sweet spot: WNW and NW are evenly matched at roughly 41% and 42% respectively, with a little more west and southwest energy appearing than in summer-the first signs of deeper Atlantic low-pressure systems aiming into the Bay of Biscay. The height distribution spreads out beautifully: a substantial portion of waves now sit in the 1-1.5m and 1.5-2m categories, with over 8% in the pumping 2-2.5m range. This translates into 4-6ft (1.2-1.8m) barrels on the better sandbars. Wind responds too: ideal conditions improve to 35%. While the sea breeze can still appear in the early month, the synoptic pattern becomes more dynamic, with frequent high-migrating lows generating offshore east/southeast winds before fronts arrive. Onshore west and northwest winds still appear about 23% of the time, but the windows between fronts are now longer and cleaner. Water temperature is a pleasant 18.4°C, air temperatures average 15.2°C, and rainfall is increasing to 3.3mm/day-autumn has truly arrived.
