Conditions at Praia das Macas in August
August: Small Windows, Warm Water
August remains firmly in the low surf season, but the swell is marginally better organised than July. Average swell height is still 1.4m (4.6ft) and period has ticked up slightly to 8.9s. The swell direction is again dominated by NNW (50.7%) and NW (35.1%), with WNW (10.2%) and W (1.5%) filling in. Most days produce only 1-1.5m (3.3-4.9ft) of uninspiring, short-period surf.
Wind conditions are nearly as bad as July, with ideal wind only 5% of the time. NNW winds blow 61.3% of the time, still frequently above 20kph, and the N wind adds 9.3% of cross-shore/onshore energy. WSW (2.6%), SW (2.1%) and SSW (1.8%) are the rare offshore directions. Water temp reaches a warm 18.3°C, air averages 20.7°C (14.2-36.3°C), and rain is almost nonexistent at 0.25mm/day. If you must surf, target the small predawn windows and bring a high-performance shortboard.
