October: The Storm Track Aligns
October is when the South Pacific storm track and the offshore wind machine finally align for Pichilemu. The average swell height is 1.7m (5.6ft) with a 12.7s period, and the directional breakdown settles into a powerful hybrid: 55.6% WSW and 35.5% SW. This creates more consistency than at any other time of the year, with clean, well-spaced groundswell wrapping into the bay. Ideal wind jumps to 72% as SSW and SW winds combine for over 52% of the wind rose, while northerly onshore winds flatten out to just a few percent. Rain has dropped to 0.66mm/day, air is a mild 13.0°C and water is still a fresh 12.6°C. October delivers the first taste of glazed, long-period perfection after the long winter grind.
