October: Autumn Swell Comes Alive
October marks the true seasonal shift. Average swell height moves up to 0.7m (2.3ft) and the period reaches 4.7s, but the most encouraging sign is the return of organised S/SSE swell: SSE jumps to 16.1% and S to 16.9%, while SW and WSW still add 11.8% and 11.0% respectively. There is also a meaningful increase in 1-1.5m (3-5ft) surf from the optimal directions, with occasional 1.5-2.5m (5-8ft) southwesterly pulses. The wind picture is mixed: ideal wind is 14%, with NE (10.5%) and NNE (8.7%) on the offshore side, but SE (11.2%) and SSE (9.9%) bring onshore and side-shore chop. This is the classic Mediterranean autumn pattern - cold fronts track south, south swell builds, and offshore NE wind can clean it up behind the front. Water temperature is 20.6°C (69.1°F), air 18.5°C, and rainfall increases to 3.1mm/day. A wetsuit and a careful eye on the wind chart are essential.
