Conditions at Los Locos in September
September: The Autumn Awakening Starts To Build
September is where the first real signs of autumn appear. Average wave height climbs to about 4ft (1.3m), the average period lengthens to 10.4s, and wind is ideal 48% of the time-already a jump from summer. NW swell remains dominant at 53.3%, supported by NNW at 22.4% and WNW at 9.9%. More importantly, 20.2% of the NW energy is in the 1-1.5m range and 11.9% in the 1.5-2m range, so the better days are starting to develop genuine power.
The return of synoptic-scale lows on the North Atlantic brings longer-period swell and more frequent S/SW wind flow ahead of fronts. Early-autumn tropical storms can also send useful pulses from the mid-Atlantic. Water temp is still warm at 19.8°C, air averages 19.1°C, and rain is still low at 1.96 mm/day. September is a transition month with plenty of upside-often the best trade-off of clean surface, warm water and building swell in the whole year.
