Conditions at Cordoama in September
September: Autumn's First Roar
September is where the season starts to turn. Swell averages 5ft (1.5m) and the period has stretched back to 10.4s, giving the waves longer-period power than the summer months. The direction is still largely NW at 47.1%, with NNW 25.5% and WNW 14.3%, so Cordoama is receiving plenty of usable energy. The crucial change is wind: NNW drops to 46.0% and the offshore window rises to 14%, meaning more dawn cleanups and more days where the afternoon sea breeze stays moderate. The ocean has retained summer warmth at 19.1C, while air temps average 21.0C. Rain remains sparse at 0.75mm/day. For local surfers, the first solid west-northwest groundswell of autumn - especially if it arrives with a SW wind - marks the unofficial end of the flat season and the beginning of the best run of the year.
