Conditions at Parlementia in September
September: The First Signs of Autumn Life
September brings the first stirrings of the winter swell machine, and Parlementia begins to shake off its summer slumber. The average swell height lifts to 1.1m (3.6ft), and the period rebounds to a more respectable 10.6s. The direction remains excellent - NW brings 53.8% and WNW 33.3% - and the distribution is notably more spread out, with 17.9% of NW swell in the 1-1.5m (3-5ft) range and 6.0% in the 1.5-2m (5-6ft) class, giving hope of some proper, head-high sets. The wind, however, is still a mixed bag: ideal offshore days are 29%, and the wind rose shows a solid chunk of W (12.0%), WNW (11.4%), NW (10.6%), and NNW (13.1%). While summer onshores are still common, the increasing frequency of cool, offshore E/SE winds ahead of early-season lows creates more clean, rideable windows. Air temperatures are still warm at 19.0°C, and water remains pleasant at 21.0°C. September is a transition month where patient surfers can find some hidden gems as the Atlantic reawakens.
