Conditions at Mejillones in June
June: Summer Slop and Strong North Winds
June is the heart of the summer wind regime. The average swell height is 1.4m (4-5ft) and the average period bottoms out at 8.5s, so most of what arrives at Mejillones is short-period NNW/N energy. NNW still leads the swell distribution with 50.7 percent, but N contributes 29.0 percent and NNE 11.1 percent, producing a lot of crumbly, wind-driven surf. The wind stats are brutal for quality: NNE reaches 45.1 percent and N 23.7 percent, with NNW at 21.7 percent-essentially a non-stop onshore/cross-onshore flow. Ideal wind is only 1 percent. Water temperature is 20.5°C, air temps 20.8°C, and rain is almost nonexistent. Expect small, lumpy conditions; the only rideable windows are the odd pre-dawn glass-off or a rare day when the thermal gradient switches to a S/SW direction.
