April: The Big-Wave Season Gears Up
April is a serious step up. The average swell height reaches 5.6ft (1.7m), the period stretches to 13.6s, and SSW swells absolutely dominate with 92 percent of the wave energy. Over half of all observations sit in the 5-6.5ft (1.5-2m) class, with 16 percent in the 6.5-8ft (2-2.5m) range and even a trace of 8ft-plus (2.5m+) energy. This is proper, heavy Pico Alto groundswell.
The catch is that ideal offshore wind is effectively zero in April. South and SSW winds combine for 86 percent of the wind distribution, with some SW wind as well, so the wave faces are often bumpy. Water temperature cools to 17.5°C and air temperatures average 19.9°C, so a thicker wetsuit starts to become necessary. Hunt for the morning glass, because the swell quality underneath is world-class.
