Conditions at Mirleft in August
August: Constant NNW Lines and Cleaner Windows
August is the low point in terms of average swell height - around 4-5ft (1.4m) - but the average period ticks up marginally to 8.4 seconds. The swell direction remains almost exclusively NNW at 94.9%, with NW contributing 3.9%. There is endless background energy, but it is short-period and lacks the size of winter groundswell; most waves fall in the 1-1.5m (3.5-5ft) range, with a smaller percentage reaching 1.5-2m (5-6.5ft).
Wind-wise, things are only slightly better than June. NNW winds are at 31.7%, NW at 13.2%, and the N/NNE quadrant adds another 17.3%, so onshore flow is still dominant. The ideal wind score nudges up to 21%, giving more hope of clean morning windows when a land breeze or weak S/SW flow develops. Water temperature reaches its warmest at 19.1°C, air temperature averages 24.7°C, and rain is minimal - classic beach weather, marginal surf.
