Conditions at La Nord in September
September: Autumn Flicker on the Horizon
September brings the first genuine shift back toward surf season. Average swell height climbs to 3-4ft (1.1m) and the average period lengthens to 10.6s, while ideal offshore wind conditions jump to 28 percent. The swell window remains weighted toward NW (54%) and WNW (33%), but the energy is slowly becoming more organized as Atlantic low-pressure systems begin dipping further south. A healthy chunk of waves sits in the 1-1.5m (3-5ft) range, with a scattering of larger 1.5-2m (5-6.5ft) sets. Water temperatures are still warm at 20.8°C, air temperatures are pleasant at 18.9°C, and precipitation increases to 2.65 mm/day. By the end of the month, La Nord can produce surprisingly fun, glassy waves as the autumn storm machine begins to stir.
