Conditions at Playa Grande in September
September: The Most Promise of the Low Season
September is the turning month. Average surf is still modest at 4-5ft (1.2-1.5m), but the period climbs to 8.8s and the swell direction rotates away from pure east. ENE (42.3 percent) is the leader, E (30.1 percent) is still significant, and NE (16.6 percent) plus NNE (5.6 percent) bring the north-east quadrant back into play. With hurricane season at its climatological peak, there is a real chance of longer-period groundswell from tropical systems moving through the western Atlantic. The wind is also the best of the summer: ideal offshore flow reaches 58 percent, the highest of the year. When a tropical swell lines up with the morning south wind, Playa Grande can deliver surprisingly punchy, clean surf in the 3-6ft (1-1.8m) range. Water temperature is 28.9°C and air is 27.9°C.
