October: The Best Wind Meets Growing Swell
October brings the first real signs of winter while still holding onto summer warmth. Average height sits at 3.9ft (1.2m), but period firms up to 9.1s and the optimal N/NNE/NNW quadrant climbs back to 15% of the wave rose. NE (36%) and ENE (39%) swells still dominate, but when a low-pressure system sets up off the Atlantic seaboard, Sosua can see long-period N/NNE pulses that wrap straight into the beach. Wind quality is excellent - 56% ideal - with lighter S/SW/SE flows and fewer aggressive trade winds. Water temp remains warm at 28.9°C, air temp averages 27.5°C, and rainfall is 2.5mm/day. October is one of the strongest shoulder months on the calendar: friendly in size, but with a waking Atlantic and clean winds, it can over-deliver.
