Conditions at El Barco in September
September: The Turning Point-Cleaner Winds and Building North Swell
September is where El Barco starts to show signs of life again. Average height ticks up to 1.3m (4.3ft), the period lengthens to 8.8s, and the N/NNE/NNW window returns to roughly 7% of the swell distribution. ENE remains the dominant source at 42.3%, with E at 30.1% and NE at 16.6%, but as the tropical Atlantic becomes more active and early autumn cold fronts brush the region, the swell direction starts to rotate north.
Wind quality improves dramatically-ideal wind runs 70% of the time-thanks to lighter trade winds and more frequent S/SSW offshore tendencies. This is a classic autumn window in the Caribbean: warm ocean at 28.9°C, air temperatures around 27.9°C, and increasing tropical moisture at 2.07mm/day. Cape Verde hurricane swells can also pump serious NE/ENE groundswell into the island. It is not yet full winter mode, but the pieces are starting to line up.
