November: Building Winter Swell
November is the transition month par excellence. Average swell height jumps to 0.9m (3ft), period to 5.2s, and ideal wind improves to 19%. The swell window is broad: SSE (14.5%) is the single most common direction, with SW (12.8%), S (11.7%) and WSW (11.2%) close behind. There is a solid block of 1-1.5m (3-5ft) and 1.5-2.5m (5-8ft) energy from the SW and WSW directions, while the broader S/SSW window adds plenty of mid-range swell. Offshore winds are frequent, with NE (12.8%) and NNE (11.8%) combining to groom the surface, although onshore SE flow (10.1%) remains a spoiler. Water temperature drops to 17.5°C (63.5°F), air averages 14.5°C and rainfall reaches 3.8mm/day - autumn's active storm track is in full swing.
