October: Spring Swell Under a Tradewind Lid
October still has plenty of ocean energy, with the average swell height around 5ft (1.6m), but the period has slipped to 8.9s, marking the transition back toward windswell. The E/ESE quadrant is dominant again - E at 23.6% and ESE at 17.9% - while genuine south groundswell begins to fade. This month is all about waiting for the ENE/E tradewind swell to combine with a rare but precious W/NW offshore wind.
And rare it is. Ideal wind drops to 14%, tied for the yearly low, while NE winds rule 31.9% of the time. The sea breeze/NE trade regime becomes relentless, and SSW/SW onshore sectors still take their share. Air temps are warming to 19.4°C and water temp rises to 18.8°C, so the winter wetsuit starts to feel less claustrophobic. In October, be ready to move fast - the best windows are usually early morning before the NE wind rebuilds.
