Conditions at Ericeira in August
August: Late Summer Lull
August remains in the summer doldrums, with an average swell height of 1.4m (4.5ft) and a period of 8.9s. NNW and NW again dominate the swell window, making up the vast majority of the energy, while WNW provides a secondary pulse. There's a slight uptick in ideal wind - 7% - thanks to more light N/NNE flow, but the overall picture is still small and wind-affected. This is the month of longboard summers, small fun peaks on the sandbars, and dawn patrol glass-offs before the daily north wind kicks in. Water temperature reaches its annual high of 17.8°C, air temps average 20.7°C, and dry, sunny weather rules. It's not the time for pumping XL groundswell, but if you're happy with playful summer waves and lots of sunshine, August has its charm.
