Conditions at Sri Lanka in June
June: Heavy Swell, Rough Seas
The southwest monsoon locks in with a vengeance as June becomes the most blown-out period of the year. Only 3% of the time does the wind blow from a favourable direction. The wind rose is almost monolithically ESE - 58.8% total, including 28.3% at 20-30kph - while SE contributes another 21.7%. That is a relentless, choppy onshore flow. Ironically, the swell average climbs to 6.9ft (2.1m) with a 14.3s period, and the direction remains largely toward SSW (41.1%) and S (30.9%), meaning the ground swell is pushing in from the NE/N. If you are lucky enough to find a brief lull in the trades, the waves have serious power, but the bumpy texture makes it hard to enjoy. Water temp drops to 28.0°C, air temp to 26.7°C, and precipitation is minimal at 1.41 mm/day - typical of the monsoon dry season on this side of the island.
