Conditions at Praia dos Molhes in August
August: Good Waves, Shorter Windows
August keeps the winter momentum with an average wave height of 5.6ft (1.7m) and a 9.2s period, but the wind quality becomes harder to come by. Ideal wind drops to 42%, and the northeast trades strengthen: NE (15.4%) and NNE (13.2%) are the dominant wind directions. Swell is strong and varied - ENE (18.7%), E (14.8%), ESE (12.2%), SE (12.8%), SSE (12.4%), and S (13.3%) - meaning there is plenty of energy to go around. The problem is that much of it arrives with onshore or cross-onshore winds. The best windows come after cold fronts when the wind swings to WSW-WNW (around 14% of observations), producing clean, powerful sandbar waves. Water temp is still 16.2°C, so the winter wetsuit is required. Quality is there, but you have to be selective.
