Conditions at Molhe Leste in September
September: The Autumn Prelude
September marks the turning point. Swell averages move up to 1.7m (6ft) and, more importantly, the period climbs back to 10.5s, signalling the return of longer-range groundswell. Direction still leans NW/NNW-66.6% of the total-but the mix begins to include more W/WNW energy as Atlantic lows reappear. Wind quality is excellent for the spot: the wind is ideal 45% of the time, with N and NNW handsomely represented, and the strength of the summer NNW gale finally relaxes. Water is still warm at 18.7°C, air temps sit near 19.3°C, and the first solid clean swells are often the best of the season.
