September: Hints of Autumn, Still Summer-ish
September is a transition month on paper, but the data still looks a lot like summer at Venice Beach. The average swell height is 2.6ft (0.8m) with a long 12.6s period, and the swell direction is very southwesterly: WSW 38.8%, SW 35.9%, SSW 13.0%, and W 11.1%. A little over 90% of waves are in the 2-3ft (0.5-1m) class, with only a small bump of 3-5ft (1-1.5m) energy.
Wind quality improves slightly from the summer low, with ideal conditions reaching 31%. The onshore W/SW flow is still prominent-WSW 17.9%, SW 12.8%, W 11.1%-but the first hints of northerly and offshore flow appear (NNE 3.6%, N 1.6%, NNW 6.1%). Water temp is the warmest of the year at 17.4°C, air averages 21.9°C, and rain is still scarce at 0.09mm/day. September is a better bet for a longboard than for critical waves.
