Conditions at Oualidia in September
September: First Signs of Life
September is a transitional month, and it's the first sign that the ocean is waking up. The average period jumps to 10.5s and swell height ticks up into the 4-5ft (1.2-1.5m) range. Directionally, NNW (64%) and NW (27%) continue to dominate, and the first early-season North Atlantic lows can send in cleaner, longer-period lines. The better days produce clean, fun surf.
Wind remains the limiting factor. Ideal offshore conditions are only 12%, with NNE and NE trades still strong, but the frequency of south and southwesterly winds is increasing compared to summer. These windows offer clean waves if you are patient. Air temp is 23.4°C, water temp is the warmest of the year at 21.0°C, and rainfall starts to creep back up at 0.69 mm/day.
