October: Big Swell Fades, Cleaner Air Returns
October is a transition month in the best way: the swell is still solid, but the wind and rain finally start to back off. Average height remains a respectable 1.3m (4.3ft) with 13.2s periods, and SSW swell is back up to 80.5%, with S (10.8%) and SW (7.8%) filling in the margins. Over 70% of the waves are in the 1-1.5m (3.3-4.9ft) solid range, with 17% still in the 1.5-2m (4.9-6.6ft) category. The return of more frequent northwesterly offshore winds, plus a drop in rainfall to 3.35mm/day and water temperature of 29.5°C, makes October a great month for cleaner, bigger surf before the winter lull.
