September: Spring Transition - Big Swells Return to Form
September is a transition month with a winter swell character. Average height is 7.5ft (2.3m) with an average period of 11.7s. SSW and SW share the lead at 21.2% and 20.1%, while S contributes 10.1%. The swell distribution still has plenty of 6.5-8ft (2-2.5m) energy, but the trend toward slightly smaller, more frequent waves is underway as spring progresses.
Ideal wind ticks up to 22%. The offshore group - S through WSW - accounts for nearly 38% of wind observations, with WSW at 20.3% and SW at 9.8%. However, ENE (11.0%) and E (10.0%) are still busy, so you need to pick your hours. Water temp is 17.6°C and air is around 16.9°C. As the high pressure belt begins to shift, September offers a nice blend of winter power and early-spring clean windows - the start of the good half of the year.
