Conditions at Sopelana in August
August: Summer Swell on Life Support
August mirrors July with an average height of 1.0m (3ft) and an average period of 9.2s, but the percentage of ideal wind edges up to 29%. The swell direction remains locked in the NW-to-NNW window - nearly 84% of all waves arrive from those two directions - so any pulse that materializes lines up well with Sopelana's exposure. Still, the Atlantic is mostly quiet, and the majority of waves fall in the 0.5-1.5m (2-5ft) range. Air and water temperatures peak in August (21.1°C and 22.2°C respectively) and precipitation is lower at 1.23mm/day. The combination of warm sea and occasional small groundswell can produce fun, longboard-friendly conditions, but don't expect pumping barrels. Mornings and offshore wind shifts are the keys to scoring.
