April: Shoulder-Season Consistency
April marks a step down in size and power. Average swell height drops to 4ft (1.3m), and the period relaxes to 10.9s, still a solid mid-length groundswell. The direction remains mostly WNW and NW, with W at 18%, though the core of the energy shifts toward the 2-5ft (0.5-1.5m) range. This is groveling-to-fun surf, perfect for a high-performance board in the 5ft+ slots. Ideal wind time falls to 41%, and the nortada starts to show up in the afternoons; the clean windows are often early, with offshore E/NE winds before the sea breeze kicks in. Air temperatures climb to 13.6°C, water temp warms to 14.6°C, and with 3.09 mm/day of rain, spring is a mix of clean, crisp mornings and mizzly afternoons.
