Conditions at Sidi Ifni in September
September: First Signs of Life
September is a quiet turning point. The average swell remains at around 5ft (1.5m), but the period climbs back to 10.1s, giving the waves noticeably more push and groom. The direction is still dominated by NNW at 80%, with NW adding 15% - a good pointer for Sidi Ifni. While many waves stay in the 1-2m range, the slight surge in period is a welcome sign that the North Atlantic is starting to stir after the summer lull.
Wind quality improves only modestly, with ideal offshore flow at 10%, but that is more than double the summer months. NNW wind is still the most common direction at 42%, so the trade wind pattern has not yet broken. Nevertheless, the first true autumn groundswell windows can deliver something special. Water temperature is at its warmest for the year at 19.0°C, air averages 22.4°C, and rainfall is minimal at 0.27mm/day - a warm, mellow month with the first hints of better surf on the horizon.
