September: Spring Transition and a Wind Lull
September is the most transitional month. Swell height eases slightly to 3.9ft (1.2m), the period holds at 12.3s, and the wind ideal percentage drops to its yearly minimum of 71%. The directional mix is still wintry: SSW 82.4%, S 16.5%, SW 1.1%, with 64.2% of waves in the 3.3-4.9ft (1-1.5m) band and 8.1% in the 4.9-6.6ft (1.5-2m) range. The extra S component keeps plenty of raw energy in the water.
Winds are overwhelmingly from the south at 82.0%, with SSW at 11.3% and SSE at 6.5%. The 20-30kph southerly pulses are still common, so early-morning glass-offs are the key. Water temperature is tied for the annual minimum at 17.1°C, air sits at 19.6°C, and rain is a negligible 0.17mm/day. September rewards patience, but the windows between wind lines are excellent.
