Conditions at Cabo do Mundo in August
August: Late Summer Lull
August is essentially the same story as July: small, short-period summer swell battling strong NNW winds. The average height remains at 4-5ft (1.4m) and the period ticks up slightly to 8.9s, but the character of the surf is still windswell-dominated. NW (45.9%), NNW (28.5%) and WNW (18.3%) make up nearly all observations, with wave heights concentrated in the 1-1.5m range. Ideal offshore wind sits at only 16%, and the wind rose is again dominated by NNW (42.2%) and NW (16.1%). The persistent trade winds create choppy, cross-onshore conditions, especially in the afternoon. Water temperature peaks at 16.9°C and the sea is warm and inviting, but the better surfers are saving their energy for September. Late August can occasionally see the first long-period swell of the autumn, so do not sleep on it entirely.
