March: Autumn Transition and a Building Southern Swell
March is the transition month. The first serious autumn frontal systems begin to reach the southwest corner, lifting average swell to 6ft (1.9m) and period to a robust 12.5s. Swell remains SW/SSW dominant (38.4% and 27.3%), but WSW increases to 5.8% and W to 1.5%, giving Lefthanders more direct, powerful lines. Ideal wind frequency jumps to 22%, and the offshore easterly quadrant (NE/ENE/E/ESE) accounts for roughly 22% of the wind rose, a notable improvement from summer. Still, SSE (21.5%) and SE (17.1%) are the most common winds, so clean windows are mostly confined to early morning before the sea breeze develops. With air temps at 20.0°C and water at 21.1°C, the autumn warmth remains, but the ocean is beginning to wake up.
