Conditions at El Porto in April
April: Peak Spring Westerly Power, But a Narrow Clean-Wind Window
April averages 3ft (0.9m) of swell at a long 12.0s period. The distribution is interesting: W and WSW share the load almost equally at 38.9% and 38.7%, with SW adding 18.5%. The W direction still produces the most consequential surf, with 5.2% of observations in the 5-6.5ft (1.5-2m) range and a full 17.6% in the 3-5ft (1-1.5m) range. That is a high-quality swell window for a spot like El Porto, and the longer period keeps the peaks lined up.
The issue is wind. Ideal offshore flow falls to 35%, and the WSW and W wind directions become the dominant players, along with a strengthening SW sea breeze. Calm, clean conditions are mostly found at first light before the onshore gradient kicks in. Water temperature is chilly for spring at 13.5°C, air averages 15.1°C, and precipitation drops to 0.63mm/day. Spring sunshine starts to open up more windows between passing fronts, but plan on dawn patrols if you want El Porto at its best.
