September: First Rumblings of Autumn
September is a month of quiet hope. The average swell height is still small at 1.5m (5ft), but the average period climbs back to 10.1s - longer than the summer months and a sign that the Atlantic is beginning to wake up. The direction profile is dominated by NNW (74.0%) and NW (19.0%), with a small but welcome WNW contribution of 2.0%. These longer-period NW wraps start to build better shape, and towards the end of the month the first serious groundswell of the autumn can appear.
Ideal offshore wind remains at a respectable 54%, and the wind rose is led by NNW at 29.7% and NW at 20.9%. Onshore SSW/SW/WSW/W winds are about 10% of the time, mostly light. Air temperatures are warm at 22.2°C, water temp is a warm 18.4°C, and rainfall is only 0.19 mm/day. September is the beginning of the climb back to excellence.
