Conditions at Sri Lanka in November
November: Monsoon Flip Turns Clean
November delivers the autumn transition at its finest. The northeast monsoon pushes back, and the wind distribution now shows a true mix of westerly and easterly flows, with ideal wind at 47%. Westerly quadrants (SSW 5.2%, SW 6.4%, WSW 9.2%, W 8.7%, WNW 3.8%) combine to challenge the still-present ESE/SE trades (ESE 17.3%, SE 16.4%). All that matters is that the offshore windows are widening daily. The swell continues to be remarkable: 5.2ft (1.6m) average height, 13.2s period, and 83.5% aimed at SSW, with 13.0% aimed at SW - so the NE swell corridor is booming. The result is powerful, clean, long-period surf as the monsoon flip takes hold. Water temp climbs to 29.0°C, air temp averages 27.7°C, and rainfall is moderate at 4.19 mm/day as the intermonsoon rains taper off. November is a favourite for many surfers.
