Conditions at Somo in September
September: The First Real Stirs
September is the bridge back to real surf. Average swell height climbs to 4ft (1.3m), the average period comes back above 10s at 10.4s, and ideal wind jumps to 38%. The northwest quadrant is still the sole supplier - NW 53.3%, NNW 22.4%, and WNW 9.9% - but the mix now contains a healthy share of 3-5ft (1-1.5m) waves, with 11.9% in the 5-6.5ft (1.5-2m) class from the NW. The ocean is waking up, but the wind can still be warm and variable; ENE/E and W/WNW winds are common, while S/SSW flows set up more often than in summer. Air temperatures average 19.1°C, water temp remains warm at 20.5°C, and rain stays moderate at 1.96mm/day. If you want a sneak peek of autumn, grab the first decent NW groundswell of the month.
