Conditions at Playa de La Concha in August
August: Holding Pattern Before the Turn
August is still in the summer lull, but there are subtle hints of life. Swell averages 3ft (1.0m) with a 9.2s period, and the NW and WNW directions continue to dominate at 64.9% and 15.9% respectively. Most surf is in the 2-4ft (0.6-1.2m) range, with the occasional chest-high set from a more active NW fetch. Offshore wind frequency is still low at 25%, and the N/NNW sea breeze regime remains stubbornly in place, making the mornings the only reliable window for semi-clean conditions.
With water temperature at 22.6°C, the warmest of the year, and air temperatures averaging 20.8°C, August is summer at its peak. The North Atlantic storm track is displaced far north, so the Bay of Biscay relies on distant low-pressure systems and trailing fronts to send anything rideable. The potential is not gone - the right NW swell combined with a SSW offshore wind can still produce a surprisingly crisp day on a shortboard - but consistency is poor. Keep expectations low and enjoy the warm water.
