Conditions at Sidi Kaouki in September
September: Autumn Stirrings
September signals the first breath of a new season. Average swell height still sits at 1.6m (5ft), but the period jumps back to 10.1s, and the ideal wind percentage climbs to 38%. The swell remains primarily NNW (72.5%), but more NW (16.3%) component appears, hinting at the return of proper Atlantic storms. The offshore sector strengthens, with NE (9.1%), ENE (2.7%), E (1.5%), and ESE (0.6%) contributing to cleaner mid-morning conditions. Water temps are at their warmest, 19.4°C (67°F), while air cools slightly to 21.6°C (71°F). This month is a tricky window: there's enough period to make the waves punchy, but consistency is still summer-like. When the first strong W-WNW lows form in the mid-Atlantic, Sidi Kaouki can suddenly come alive with 6ft+ bombs.
