September: First Signs Of Life
September is the comeback month. Average swell height is still a modest 3-4ft (1.1m), but the period lengthens to 10.5s, and the North Atlantic is beginning to stir again. Swell direction remains dominated by NW (50.4%) and WNW (31.6%), with W adding 8.9%, and although most waves are still small, the occurrence of 1.5-2m (5-6.5ft) sets begins to increase. The wind pattern starts to soften from its summer peak: NNW is still largest at 36.4%, but the favorable offshore window expands to 14%. Water temperature peaks at 18.7°C, air averages 19.9°C (min 14.1°C, max 31.2°C), and rainfall nudges up to 0.89 mm/day. There are now genuinely good windows where fresh autumn groundswell meets a dawn easterly offshore - the first real taste of the season to come.
