March: The Winter-Trade Transition
March is a transition month written all over the numbers. Average size remains a healthy 7.5ft (2.3m), and the period comes in at 11.3s, so winter muscle has not left the building. But the distribution begins to shift: ENE swell (14.3%) now rivals NNW swell (12.6%), while NE and NNE combine for another 24%. Trade-generated swell starts to mix with fading North Pacific groundswell, giving a more east-oriented wave.
The wind regime announces the changing season. ENE winds jump to 31.8% and E winds to 18.1%, while ideal offshore flow falls to just 14%. That means more surface chop and a smaller window for Kealia to show its true quality. Still, the energy level is high enough that even a modest 5-8ft (1.5-2.5m) trade swell can produce clean walls if a westerly breeze aligns. March averages 3.11mm/day of rain, the wettest month on the books, with water at 23.7°C and air at 22.6°C.
