January: Winter Groundswell at Full Throttle
January delivers the most powerful average conditions of the year at Mejillones. The swell rose shows a striking 34.8 percent from the NNW, 19.5 percent from the NW and 7.3 percent from the N, meaning nearly 62 percent of the swell arrives from an optimal direction. With an average height of 2.2m (7ft) and an average period of 12.9s, this is proper long-period groundswell-powerful, heaving and worth checking as soon as the wind drops. Winds are the limiting factor, though: NNE (16.7 percent) and NE (22.7 percent) dominate, both of which are onshore or cross-onshore for a beach facing NNW. The 19 percent ideal wind figure is the second-best of the year and is usually tied to anticyclonic calms or S/SW flow behind offshore low pressure. Expect water temperature around 19.1°C, air temps averaging 17.6°C and occasional winter rain (0.45mm/day) to keep the air fresh. When the wind plays ball, January at Mejillones is as good as it gets.
