Conditions at Parede in September
September: The Autumn Switch Flickers On
September is the turning point. Swell size is still modest at around 5ft (1.5m), but the average period jumps to 10.5s, signaling the return of true long-period groundswell. NW power still dominates - NW 42%, NNW 26% and WNW 19% - but the SSW/SW window begins to open again, and when an early-season low-pressure system sends a WSW swell toward Parede, the quality is far better than anything seen in summer.
Wind is also more favorable: ideal offshore conditions return to 48%, the best score since winter, while the NNW wind weakens to 43%. Air temperatures are still warm at 19.9°C, water temp is at its annual high of 18.4°C, and rain remains light at 0.89mm/day. This is the month to start watching the forecast again.
