September: Spring Swell and Shifting Winds

The wave rose is more balanced between WSW (45.3%) and SW (39.6%), with W adding 6.6% and a trace of WNW energy. There are still solid 1.5-2m (5-6.5ft) groundswells, but the overall energy is starting to trend down through the month. The quality is still there, especially early in September before the spring transition takes full hold.
Ideal wind conditions run at 34%, with S (16.3%), SSE (12.4%) and SSW (13.1%) providing the most common offshore flow. NNW wind is still present but less dominant. Water temperatures begin to warm at 14.9°C, air temperature averages 14.8°C, and rainfall drops to 0.84mm/day.
