Conditions at Sabon in September
September: The First Spark of Autumn
September is when the Atlantic begins to wake from its summer slumber. Average swell heights rise to 1.7m (5.6ft) and periods lengthen to 10.4s, signaling the return of more organized, longer-period groundswell. The NW sector is especially active, with NW at 27.3%, WNW 20.3% and NNW 16.7%, and the height distribution broadens to include more 1.5-2.5m (5-8ft) waves. The first true XL day of the season isn't out of the question.
Winds also improve, with the ideal wind percentage jumping back to 37%. While NE remains the single most common direction at 15.2%, SSW and SW winds are increasingly prominent. Water temperature is still warm at 17.2°C, air averages 17.9°C, and rain is a modest 2.01mm/day. September is the perfect month to re-dust the quiver - the autumn fetch is starting to load up.
