Conditions at Encuentro in September
September: Autumn Transition Begins
September is where the season starts to turn. The average swell height is still just 1.2m (4ft), but the period jumps to 8.8s and the direction mix is much healthier. ENE is back on top at 49%, NE adds 20%, and the optimal N-NNE-NE-ENE window totals 76%. This is also the best month of the year for wind: the ideal wind score reaches 39%, the highest in the data set, and winds are lighter on average. The result is a month with real potential for clean, rippable waist-to-shoulder-high surf, plus a genuine chance of hurricane or tropical storm swell from the Atlantic. Water temp is at its annual peak of 28.9°C, air temps average 27.9°C, and rainfall is increasing at 2.57 mm/day. September is a sneaky-good month for those who can read the tropics.
