March: Autumn Shifts Begin
March marks the first real shift in the annual cycle. The average swell height is still 1.3m (4ft), but the average period climbs to 11.9 seconds, giving the incoming SSW and SW swells a bit more push. The wave rose remains SSW-heavy at 39.7% and SW-heavy at 35.4%, with S swell adding 9.9% and SSE 6.3%. The bulk of the waves are in the 1-1.5m range, and there is a notable increase in 1.5-2m swell compared to the summer months, especially from SSW and SW directions.
The wind regime starts to improve, with ideal offshore flow now 30% of the time. W at 7.0%, WNW at 5.9% and NNW at 5.9% provide more clean windows, although E to ESE to SSE sea-breezes still dominate many afternoons. Rain remains modest at 1.34 mm/day, water temperature drops to 18.8°C and air temperatures cool to 17.5°C. The first strong frontal passages of autumn are starting to spin up, and Bells begins to show more of its classic potential as periods push toward 12 seconds.
