Conditions at Las Salinas in December
December: Winter Solstice Delivers Deep Water Grist
December rounds out the year with the same high-energy recipe that opened it. Average swell height is 1.7m (5.5ft), the average period is 12.6s, and ideal wind sits at 25%. The wave direction is slightly more varied than midwinter: NNW 38.7%, NW 16.2%, N 11.0%, NNE 10.3%, with a bit more WNW (5.2%) and W (2.0%) energy in the mix. The wind rose shows NE at 21.7%, NNE 16.0%, ENE 13.5% and N 3.6% - a mostly offshore signal, though the ENE/E component can add a slight cross-offshore texture. Still, the 25% ideal wind figure means plenty of workable windows. Winter storms are frequent, water temperature is 20.2°C and air averages 19.4°C, so you will need the rubber. With rain at 0.66mm/day, keep an eye on the charts; the best days are often the rarer clear, post-frontal mornings with lined-up NNW swell and offshore N/NW wind.
