Kohala Lighthouse • Statistics for November

November: Building the Foundation for Winter

November is where the average stats finally start to flex. The mean swell height pushes up to 1.9m (6.2ft) - tied for the highest of the year - and the period climbs to 11.3s. The direction mix sees a genuine injection of north energy: NNE moves to 7.4%, NE to 17.5%, and the N/NNW directions add another 2.7%, putting the preferred north quadrant at just under 28% of all swell. The heavy hitters are still ENE (39.6%) and E (22.8%), but the size is undeniable: ENE logs 19.1% in the 1.5-2m range and 11.6% in the 2-2.5m range, while NE contributes 9.0% and 3.7% respectively. Trade winds still howl from ENE/E 83.6% of the time, but ideal wind days improve to 7%, and frontal systems become more frequent as precipitation rises to 3.52 mm/day. Water temp settles at 25.9°C. November is a month of building momentum - the surf is big, occasionally great, and every passing low improves the odds of a classic day at the lighthouse.
