December: Summer Lines Return to Pulpos
December is the beginning of the Peruvian summer and the swell settles into a fun, mellow rhythm. The average height drops to around 5ft (1.5m) with a 12.8s period, still long enough to hold together. SSW remains the dominant swell source at 87.7 percent, but the distribution shifts back toward smaller surf: 49.6 percent of the SSW energy is in the 3-5ft (1-1.5m) class and 34.3 percent in the 5-6ft (1.5-2m) class. SW adds another 10.0 percent, so the waves that arrive are lined up nicely for the beach.
Wind quality is the real issue. Ideal offshore flow sits at 0 percent for the month, with S, SSW and SW winds combining for over 91 percent of observations, including a healthy chunk of 10-20kph SW wind. Even so, air temperatures average 19.3°C and water temperature is 17.4°C, and the light nature of most winds means the surf can be clean in the early mornings. It is a classic longboard session month for surfers who know where to sit, with the occasional head-high set keeping things interesting.
