Conditions at Sri Lanka in July
July: Same Onshore Grind, Slight Size Increase
July offers little reprieve. The ideal wind percentage bottoms out at 2%, as ESE winds roar to 59.7% (with 33.3% in the 20-30kph class) and SE adds 29.7% - both squarely onshore for an ENE-facing spot. The swell maintains its winter-hemisphere peak: average height 7.2ft (2.2m) with a very powerful 14.4s period. Direction-wise, the energy is split between SSW (35.2%) and S (33.3%) aimed, so the source is predominantly NNE and N. If the wind ever relents, there's a heavy, rushing long-period swell waiting, but the surface conditions often render it unrideable except for the brave on a 5'4". Air temps cool a touch more to 25.8°C, water temps down to 27.0°C, and rainfall is almost non-existent (1.03 mm/day).
