September: The Atlantic Wakes From Its Summer Nap
September is the transition month that gets surfers excited again. Average swell height climbs to 1.5m (5ft) and the period lengthens to 6.9s, a sign that the North Atlantic is beginning to generate more organized energy. The optimal S to WSW sector supplies about 28% of the wave rose, with a rising share of 1-2m waves. Yet the wind remains a summer holdover: NW and WNW winds are still frequent, and the ideal offshore N-NE wind occurs just 8% of the time. E/ESE winds are also common, which at least keeps some shape in the water. Water temperature is still pleasant at 15.5°C, air temperatures average 13.6°C, and rainfall begins to climb to 4.8mm per day. September won't consistently fire, but when an early autumn low tracks across the Atlantic and sends a solid SW swell, Lista can serve up excellent, warm-water waves before the winter chill arrives.
