Conditions at Avalanche in September
September: Spring Light at the End of the Tunnel
September is a transitional spring month: still heavy, with 7.5ft (2.3m) average swell and 11.7s periods, but the storm track starts to lose a little intensity. SSW swell still leads at 21.2%, with SW at 20.1% and S at 10.1%. The wind picture is a mixed bag-WSW is the strongest single direction at 20.3%, but E and ENE combine for 21.0% and SW appears 9.8% of the time. Ideal offshore wind is up to 22 percent. Water temperature sinks to 17.6°C before the spring rebound, and air temps average 16.9°C. The more promising sign is the gradual reduction of strong NW/NNW wind, meaning the windows of clean, lined-up swell become slightly more frequent by the end of the month.
