October: Peak SW Swell Under Persistent Spring Onshore Winds
October matches September for swell size and direction: 6ft (1.8m) average, 13.1s period, and 78% of waves from the SW. The WSW-facing beach is fully exposed to long-period Pacific groundswell, and there is no shortage of raw energy. More than 43% of waves sit in the 5-6.5ft (1.5-2m) range, with 21% above 6.5ft (2m).
Unfortunately, the wind is as bad as any month, with just 1% ideal wind. SSW at 37% and SW at 25% dominate, with WSW adding another 13%. During October the South Pacific High is firming up, and the pressure gradient generates nearly constant onshore flow along the Chilean coast. If you can find a dawn patrol with light winds and a passing offshore pulse, the swell will be memorable; otherwise expect heavy, bumpy, closed-out sections. Water temp is 12.8°C, air temp 16.2°C, and precipitation is low.
