September: Autumn Re-Awakening
September is where El Brusco starts to wake up. The average swell height rises to 3-4ft (0.9-1.2m) and, more importantly, the average period jumps back to 10.4s, signaling the return of true groundswell after summer's short-period slop. The NW quadrant still rules, with NW, NNW and WNW providing around 85% of the energy, and there is a noticeable increase in 4-6ft (1.2-1.8m) sets plus a few overhead waves from late-season hurricanes or deep North Atlantic lows. With the ocean transitioning, ideal wind frequency climbs to 36%, and the first SSW/SW pulses of autumn become more common. Water temperatures are still pleasant at 20.3°C, air temps average 19.1°C (min 12.1°C, max 31.0°C), and rainfall remains modest at 1.96 mm/day. September often delivers the best combination of warm water and genuine NW groundswell all year - a sleeper month at El Brusco.
