Conditions at Kovalam Beach in September
September: Swell Still Strong, Monsoon Wind Eases Slowly
September is a transition month with a split personality. The average swell height drops to 4ft (1.3m), but the period stays at a powerful 11.1s. Swell direction is good, with SW at 37.9%, SSW at 30.9%, and WSW at 20.5%. That's plenty of southwest groundswell for the west-southwest-facing beach. The issue is still wind - ideal offshore flow sits at only 4%, and NW/WNW winds blow 34.2% and 29.1% respectively. However, the monsoon is beginning to weaken, so occasional windows of lighter winds or offshore flow can produce excellent, groomed waves. Water temp is 27.1°C, rain remains high at 6.23 mm/day, and air temps are around 26.0°C.
