April: South Swell on the Rise, but Wind Gets Fickler
April is a genuine transition month. Average swell height falls to 0.7m (2.3ft), and average period is still a modest 5.0s. The direction tables show one of the highest combined favorable swell totals of the year: S (16.0%), SSE (14.8%), WSW (14.2%), SW (13.3%) and SSW (8.3%) add up to over 53%. The beach is receiving plenty of south-southwest energy, but it is concentrated in the 0.5-1m (1.5-3ft) class. The bigger 1.5-2m (5-6ft) waves become noticeably scarcer, though they still appear from WSW (1.9%) and SW (0.9%).
The wind story becomes less friendly. The offshore quadrant fades to about 20%, while SE and SSE winds each crack 10%, bringing more humid and lumpy airflow. Ideal surf wind drops to 12%. Air temperatures warm to 14.1°C, water temperature is 15.4°C, and rain averages 2.0 mm/day. April can still throw a few fun south-swell days during strong Mistral or Sirocco events, but the consistency of winter is gone. Keep expectations modest and the volume high.
