Conditions at Sri Lanka in August
August: Still Gnarled by Trade Winds
August remains in the grip of the southwest monsoon, with the wind still blowing from the wrong side for this break. The ESE (52.4%) and SE (36.9%) winds produce a strong onshore component; ideal wind only reaches 4%. However, the swell is at its biggest of the year: 7.2ft (2.2m) average height and a 14.4s period. The wave direction is dominated by SSW (49.7%) and S (24.3%), keeping the NE/N source active. So while the ocean is full of energy, the persistent trade winds create bumpy, lined-up but ultimately difficult conditions at this exposed corner. Water temp drops to a cooler 26.5°C, air temp averages 25.5°C, and rain is rare (0.65 mm/day). If you can find a wedge or a reef sheltered from the wind, there are still potential moments, but plan to be patient.
