April: Pumping Swell With a Side of Onshore Wind
The austral autumn is in full swing and the Southern Ocean is firing. Average swell height rises to around 6ft (1.7m) and the period extends to 13.6s - one of the best of the year. SSW swell becomes a juggernaut at 92% of the directional distribution, with over half of all readings in the 5-6.5ft (1.5-2m) range and more than 16% pushing into the 6.5-8ft (2-2.5m) class. That means well-overhead, powerful waves. If you are looking for size, April delivers, and the southwest-facing layout of El Silencio lines up perfectly with this direct SSW groundswell.
The trade-off is wind. Ideal wind drops to 4%, and the surface is frequently under the control of S and SSW breezes, which together account for nearly 60% of observations. Speeds stay mostly under 20kph, so it is not constantly blown out, but clean conditions are limited. Water temperature cools to 17.5°C while air temperatures average 19.9°C; with the strong April sun and dry desert climate, a 3/2 wetsuit is workable. Look for the early hours and the rare E-flow days to make the most of this pumping swell.
