November: Quality Returns Alongside the Storms
November is a serious surf month at Mejillones. Average height is back to 2.0m (6-7ft) and average period reaches 11.9s, with a very North Atlantic-like distribution: NNW 40.7 percent, NW 19.4 percent, N 9.4 percent and WNW 3.4 percent. These are the first true winter swells, and the spot's NNW exposure lines them right up. Wind is still mixed, but the northeast trades are finally weakening-NNE and NE both sit around 23.8 percent-and ideal wind improves to 17 percent. The southwest quadrant (S/SSW/SW/WSW) contributes enough days to give genuine offshore or side-offshore surf. Water temperature holds at 21.7°C, air temps drop to 20.6°C, and rainfall rises slightly to 0.54mm/day. November is one of the most underrated months: the swell is sizeable, the period is long, and the wind often plays ball.
