Conditions at Coco Pipe in September
September: The Sleeping Giant of the Year
September is the sleeping giant month at Coco Pipe. The averages still look modest - 4ft (1.2m) and 8.8s - but the directional mix has improved dramatically: ENE (49%), NE (20%) and NNE (7%), with pure E down to 21%. That puts 76% of the swell inside the desirable N-NE-ENE window. The average period has climbed out of the 7s and into the mid-8s, making the surf punchier and more organised.
Wind quality also improves. The ideal wind score jumps to 34%, helped by more light-variable mornings and occasional S/SW flow. The ESE trades are still present at 32%, but they are less dominant than in midsummer. This is the first month where clean, long-period hurricane swell can put Coco Pipe well overhead. Water temperature peaks at 28.9°C, air temperature averages 27.9°C, and rainfall rises to 2.57 mm/day.
