Conditions at Sao Lourenco in August
August: Small Swells and Faint Hope
August remains locked in the summer low, but there are subtle signs of life. Average swell height is still only 1.4m (4.6ft), but the average period ticks up to 8.9s and ideal wind improves slightly to 5 percent. The swell direction is still overwhelmingly NNW (50.7 percent) and NW (35.1 percent), with WNW adding 10.2 percent.
NNW winds remain dominant at 54.7 percent, so clean conditions are rare. That said, the slightly longer periods mean an occasional NW groundswell can produce fun-size, rippable waist-to-chest-high waves if the wind cooperates early in the morning. Water temperature peaks near 17.8°C and air averages 20.7°C.
