Conditions at Cova da Alfarroba in August
August: Late Summer Lull with a Glimmer of Autumn
August remains firmly in the low season, but there are subtle signs of life. The average swell is still 5ft (1.5m), while the period ticks up slightly to 9.0 seconds - marginal, but a touch more organized than July. NW (34%) has taken a bigger share from NNW (48%), giving the beach more of the ideal northwest angle. Wind is still tricky: NNW dominates at 61%, with N (9%) and NW (8%) adding more onshore texture. Ideal S/SSW/SW winds only reach 11%, so clean days are rare but not impossible. Rain stays almost absent at 0.34mm/day, with air temps at 19.9°C and water temp at its peak of 18.5°C. If you're chasing warm-water small waves, August rewards the opportunistic surfer who can grab the dawn windows before the northerly wind machine kicks in.
