Conditions at Lafitenia in August
August: Warm Water, Small Waves
August offers a slight uptick in consistency compared to July, but it is still firmly summer doldrums. Average swell height stays at 0.9m (3ft) with a 9.4s period. NW swell dominates even more heavily at 66.8%, while WNW accounts for 25.7%. Most waves sit in the 0.5-1m (1.5-3.3ft) range, though there is a notable chunk of 1-1.5m (3.3-5ft) waves at 17.2%. These are fun-sized, rippable waves when the wind lines up, but there is very little heavy, powerful surf.
Ideal wind percentages recover slightly to 18%, boosted by the first weak Atlantic fronts brushing the Bay of Biscay. Still, late August can see the earliest long-period pulses from developing northern storms, giving a small but meaningful upgrade in wave quality. The water temperature reaches its annual maximum of 22.9°C, with air temperatures averaging 20.8°C and rain at just 1.73mm/day. For most surfers this is longboard season, but if a late-season low forms early, Lafitenia can offer some surprisingly fun and warm waves.
