Conditions at The Cribbar in September
September: Autumn's First Sigh
September is the pivot point of the year. Average swell height rises back to 1.3m (around 4ft), and the period stretches to 9.6s, injecting some real intent into the Atlantic. W swell still rules at 40.2%, with WNW at 19.0% and NW/NNW adding another 12.8%, meaning the Cribbar's exposure is fully engaged. More importantly, the late tropical and early extratropical storms start to show up on the charts, and the 2m+ (6ft+) class reappears in small doses. The wind is ideal 23% of the time, and as water temperatures cool to 16.4°C, the atmosphere becomes more comfortable for autumn sessions. Air temperature averages 15.3°C, precipitation is picking up to 2.59 mm/day, and the water is still warm enough for a thinner wetsuit. September will not yet deliver the daily rail-hammering of winter, but the longer-period W/WNW swells signal that the Cribbar is waking from its summer nap.
