Conditions at Patos in September
September: Autumn's First Pulse
September is when the ocean begins to remember it's a surf spot. The average swell returns to around 3ft (1.0m) and the period climbs back to 10.5s - the first legitimate long-period swells of the season. Swell direction is dominated by WNW (32.5%), NW (23.7%) and W (14.9%), exactly the directions that work at Patos. Ideal wind improves to 31%, and while NNE flow still sneaks in, the S/SW offshore sector becomes more regular. Water stays warm at 16.5°C and air averages 18.8°C, so autumn surf is still comfortable. It's a fair month with occasional gems; once the Atlantic lows start rolling again, Patos usually lights up.
