Conditions at Auroville in September
September: Southwest Monsoon Exit
September is the transition out of the southwest monsoon. The average swell height is 2.6ft (0.8m) and the period is still a healthy 8.6s, but the ideal surfing wind eases to 53%. Swell direction is still mostly from SSE (53%) and S (33.7%), though a meaningful SE component reappears at 9.5%. This is the beginning of the directional shift that will eventually bring Auroville back to life.
Winds are still predominantly from the SW and WSW, meaning clean, offshore mornings are common, but the onshore E/ESE/SE breezes begin to creep back around 13% of the time. The larger S/SSE swells are still not ideal, so surf remains in the 1.6-3.3ft (0.5-1m) range with occasional 3.3-4.9ft (1-1.5m) sets. Water temperature is still warm at 29.1°C, air temperature is 28.6°C, and rain increases to 3.83mm/day as the northeast monsoon wet season approaches. A month for patient surfers, especially as the first real E/SE swells can appear if a Bay of Bengal depression forms.
