Conditions at Rodiles in September
September: The First Autumn Pulse
September is where things begin to stir again. Average swell rises to around 3-4ft (1.1m) and the average period reaches 10.2 seconds, a noticeable jump from the summer lull. The directional signal remains strongly NW, with NNW contributing heavily, and a bigger share of waves pushes into the 3-5ft (1-1.5m) category. Offshore wind odds improve to 32% as the first synoptic lows reach the eastern Atlantic. The ocean is still warm-water temperature 19.8°C-and air averages 18.3°C, making early autumn the most comfortable time of year for surf. Consistency is not yet winter-grade, but the windows between high-pressure systems are wider and the quality is on the upswing. September is the classic month for uncrowded dawn sessions as the sea breeze comes later and the Atlantic delivers the first real groundswell of the season.
