October: Transition Time as Winds Turn Cleaner
October is the swing month when Troncones starts to trade late-summer chaos for cleaner autumn conditions. Average swell height drops only slightly to 1.5m (5ft) and the period is a strong 13.4s. The direction mix is still beautifully concentrated in the sweet spot: SSW 72.7% and SW 15.4%, with the biggest chunk in the 1-1.5m (3-5ft) range (45.9%) and another 23.6% in the 1.5-2m (5-6.5ft) category. Those are ideal, rippable groundswell conditions.
More importantly, the wind pattern starts to shift back toward offshore stability. Ideal winds rise to 42%, with N/NNE/NE/ENE frequencies all increasing while S/SW winds slowly fade. Rain drops to 3.35 mm/day and water temp relents slightly to 29.8°C. October can be fantastic if the tail end of the tropical swell season meets an early autumn high-pressure system bringing north winds. You get the late-season size and the winter-like clean surface - a sneaky good month for Troncones.
