April: The Autumn Window Opens Wide
April is where Betty's Bay really starts to shine. The average swell has climbed to 7.5ft (2.3m), the period to 12.0s, and the ideal-wind percentage jumps to 31% - nearly double mid-summer. The wind regime is in transition: E/ESE/SE totals are still substantial, but WNW (7.8%), NW (9.7%) and NNW (8.0%) are now very much in play, offering frequent clean offshore mornings. Swell distribution remains excellent, with SW (25.0%), SSW (19.4%) and S (8.9%) composing the bulk, alongside a growing WSW component (7.5%) - a signature of stronger, more westerly tracking fronts.
