September: Autumn's Awakening
September is when Doolin starts waking up. The average swell rises to 5ft (1.5m) and the period lengthens to 10.2s as Atlantic lows begin to re-enter the picture.

Wind still favours the WSW and SW quadrants (WSW 11.4%, SW 9.4%, W 9.2%), but the offshore quadrant includes a solid ENE (4.0%) and NNE (3.8%) showing, bringing ideal conditions to 17%. Water is still warm at 15.7°C, air at 13.9°C, making it a fantastic month to chase a clean groundswell. The message is simple: the long summer lull is over, and the Point is starting to throw again.
