Conditions at Campelo in August
August: Still Small, But a Hint of Autumn
August sits at the tail end of the summer doldrums. Average swell height is around 4-5ft (1.2-1.5m), period 9.1s, and ideal winds are only 21%, but there are subtle signs of change. NW swell is the clear leader at 31.4%, with WNW and NNW making up another 21.4% and 18.9%; most waves are in the 1-1.5m range, and the longer-period pulse occasionally arrives out of the North Atlantic. The NE wind machine is still running, with NE at 19.1% and ENE at 11.8%, but south-west offshore winds are slightly more common than in July. This is the warmest month: air averages 19.1°C and water temperature peaks at 18.5°C. August surf is inconsistent, but a late-season Atlantic low can supply the first proper swell of the autumn while the water is still warm.
