April: Autumn Groundswell and Better Windows
April is where the South Atlantic genuinely begins to wake up. Average swell height rises to 7.9ft (2.4m) and the period stretches to 12.2s, placing the surf at the powerful end of the spectrum. Swell directions lean heavily on SW (23.3%), SSW (19.3%) and WSW (7.6%), with a larger share of the energy now arriving in the 6.6-8.2ft (2-2.5m) category and a noticeable bump in over 8ft (2.5m) groundswell from the W/SW sectors. The wind picture turns slightly more favorable: ideal N-NE offshore flow rises to 13%, while SSE (25.7%) and SE (20.1%) still make up the majority. NNW winds also begin to appear at 12.0%, giving surfers more chances for cleaner conditions between frontal passages. Air temps fall to an average of 17.7°C (12.9-26.8), water temp drops to 16.0°C, and precipitation jumps to 1.24mm/day. April is a prime shoulder-season month for experienced big-wave surfers, with more consistent power and improved odds of a clean offshore.
