October: Big Swell on the Autumn Edge
October keeps the green-season swell machine rolling. The average height is 4.3ft (1.3m), the period is 13.0s, and the favorable S/SSW/SW/WSW quadrant accounts for 99.2% of all wave energy. SSW remains the anchor at 78.5%, but SW is now a strong secondary at 15.0% as autumn storm tracks start to shift. The wave heights are prime: 59.9% of SSW at 3-5ft (1-1.5m), 13.9% at 5-6.5ft (1.5-2m), and the SW direction adds 5.6% in the 5-6.5ft range.
Ideal wind holds at a respectable 54%, with the offshore quadrant at 31.1% and onshore S/SSW/SW/WSW at 23.0%. Rain eases to 6.00mm/day, and water temps are still tropical at 29.2°C. October is a month of powerful swells and slowly improving wind consistency. The outer sandbars are often holding; if the tides align and you catch a morning offshore, it can be as good as any month of the year.
