Conditions at Cortegaoa in August
August: Small but Not Hopeless
August remains in the summer lull, with average swell at 3ft (0.9m) and period at 9.0s. Ideal wind conditions are only 12%. The swell is again NW (51.0%) and WNW (40.2%), but most of it is in the 0.5-1m (2-3ft) bucket. The persistent NNW (45.8%) and NW (14.5%) winds blow across the beach, ruining many sessions. Still, August is a classic European beach month; water temps are 17.1°C (63°F), air averages 20.4°C (69°F), and rain is just 0.75 mm/day. The best surf comes with an easterly breeze and a pulse of south-tracking hurricane swell - rare, but when it happens, Cortegaoa can be surprisingly fun.
