Conditions at Los Patos in September
September: Autumn's First Whisper
September marks the slow switch back toward autumn. The average swell height is still modest at 4ft (1.3m), but the average period climbs to 10.3s, a sign that more organized Atlantic energy is on the horizon. The direction mix improves markedly: NNW jumps to 37.9%, NW reaches 7.1%, N contributes 22.5%, and NNE drops to 29.4%. That is a much better alignment for the beach.
Ideal wind sits at 25%, with NE at 32.1%, ENE at 22.9% and NNE at 15.7%; however, the transition season also starts to deliver more WSW/SW offshore options. Surf heights remain mostly in the 3-5ft (1-1.5m) range with occasional 5-6.5ft (1.5-2m) sets, but the longer period makes them push harder and hold better through the lineup. Air temperature is warm at 22.6°C, water temperature is at its annual warmest around 23.8°C, and rainfall is still low at 0.34 mm/day. A great month for building into the season.
