Conditions at Ofir in September
September: Autumn's First Punch
September is a critical transition month at Ofir. The average swell height rises to 1.6m (5.2ft), and the average period stretches back to 10.4 seconds - the first real return of long-period energy since spring. Swell direction remains ideal: NW at 34.1%, WNW at 22.8%, NNW at 22.4%, and W at 6.2%. The wave heights build through the 1-2m (3-6.5ft) range, and the bigger WNW sets start to show more consistency as the Atlantic storm track awakens.
Wind conditions improve noticeably compared to summer. Ideal wind jumps to 33% of the time, and while NNW (27.3%) and NW (10.5%) still dominate, the return of easterly/southeasterly offshore flow from developing Iberian highs provides more clean, open windows. This is a month of opportunity: the water is still warm at 16.6°C, air averages 19.2°C, and rainfall begins to climb (2.04mm/day), setting the stage for the late-season gold.
