Conditions at El Silencio in December
December: Summer Arrives With Cleaner, Smaller Lines
December closes the year with the lowest average swell height since January, around 5ft (1.5m), and a period of 12.8s. The swell direction remains highly favourable, with SSW at 88% and SW at 10%. Most of the energy is in the 3-5ft (1-1.5m) range - about 57% of all observations - with a solid secondary peak in the 5-6.5ft (1.5-2m) range. In other words, December offers mellow long-period swell that is ideal for groveling and more user-friendly surfing, provided the wind plays ball.
The wind is only marginally more cooperative than in winter. S, SSW, and SW winds still dominate, but the 0-10kph class is large, and ideal wind remains at 1%. The warmer air at 19.3°C and water at 17.4°C make dawn patrol pleasant, and the dry desert climate is at its most inviting. December is not a month for chasing huge El Silencio; it is a month for finesse, timing, and squeezing every drop out of the occasional clean, glassy morning.
