Conditions at Alwars in September
September: Monsoon Retreat - Clean Windows Return
September marks the slow retreat of the southwest monsoon. The swell mix remains stubbornly south-based - S at 60% and SSW at 37% - while the preferred NE/ENE/E window shows nothing. Average height is 3.3ft (1.0m), period 10.8s, so there is plenty of long-period energy in the ocean, but most of it is hitting coastlines with a more southerly orientation. Alwars gets the leftovers: small, heavily refracted waves at best.
The wind picture brightens a little. WSW remains dominant (53%) but SW picks up to 34%, and 24% of observations are in the ideal offshore window. Daytime onshore tendencies are weaker than mid-summer, and the rain total is 3.30 mm/day. Water temps hold at 27.1°C while air averages 28.0°C. For the patient surfer, September is best for longboard sessions on clean but small days, with the first hint of autumn's transition still a few weeks away.
