Conditions at Jailbreaks in September
September: Signs of a Shift
September sits on the shoulder of the monsoon, and there are subtle signals of change. Average swell comes down slightly to 1.1m (3.6ft), period is still strong at 8.4s, and the direction distribution starts to rotate: S energy is still high at 18.9%, but SSE (15.3%) and WSW (16.3%) battle for dominance. The W (31.5%) and WNW (26.7%) winds continue to blow offshore, yielding 49 percent ideal conditions. While the overall swell is still mostly south and southwest, the increasing SSE component is enough to send the first groomed waves through Jailbreaks on a more regular basis. Rain is at its wet peak (6.02 mm/day), with air at 27.5°C and water at 29.1°C. Not yet consistent, but the reef starts to wake up.
