October: The Storm Track Reawakens

The S-SSW-SW-WSW window is fully active, with WSW and SW providing most of the heavier sets; a good share of the energy sits in the 5-8ft (1.5-2.5m) range, with bigger days appearing when lows strengthen. Ideal wind is 28 percent, and while SSE/S/SE winds remain common, post-frontal offshore flow from ENE/NE can turn the lineup on. Air averages 8.0°C, water falls to 10.6°C, and precipitation is at its wettest of the year at 10.07mm/day. The fall pattern brings combo swell and an anything-can-happen vibe.
