October: Swell Is There, But Winds Play Hard to Get
October is a frustrating month on paper. The average swell height is still a solid 1.3m (4-5ft) with a 10.0s period, and the south quadrant is active-SSE 26%, S 23%, SE 21%, ESE 19%. Yet ideal wind is only 42%, the lowest of the year, as the E/ENE trades blow stronger and more consistently and onshore S/SSW/SW flow becomes more frequent. The result is plenty of waves but often lumpy, textured conditions. Still, spring cold fronts can produce windows of clean, long-period south swell if the wind flips to the north overnight. Water sits at 20.6°C, so don't let the warm air temps fool you.
