Conditions at Machico in August
August: Warmest Water, Smallest Swell Window
August is the peak of the summer slow season. Average swell height stays at 1.4m (4.6ft), period ticks up slightly to 9.1s, and the wave directions are split between NNW (33.5%) and NNE (33.0%)-a textbook trade-wind sea. The optimal E/SE swell quadrant is essentially at zero percent, so any surf comes from the north quadrant wrapping into the bay. The saving grace is wind: ideal conditions occur 58% of the time, with NNE (47.7%) dominating and NNW flow at 14.3%. Water temperature reaches its annual maximum of 23.1°C, air averages 22.6°C, and rain is almost nonexistent at 0.28 mm/day. Expect small, clean surf and a summer quiver; Atlantic groundswell is minimal.
