March: Trade-Wind Transition, Still Waiting on South Swell
March marks the beginning of the trade-wind surge: ENE wind frequency jumps to 31.8% and E to 18.1%, while the North Pacific waverose still shows plenty of NNW (12.6%), NNE (12.1%) and ENE (14.3%) energy. Average open-ocean heights hold at 7.5ft (2.3m) but the period eases to 11.3s. At Kalapaki, the south-facing exposure remains mostly starved - SE/SSE/S/SSW directions make up only 0.9% of the swell distribution. Most of those occurrences are 3-5ft (1-1.5m) and 5-6.6ft (1.5-2m) pulses from the southeast, so there are occasional clean, rippable days.
Offshore N/NNW/NW flow drops to 13.4%, and the ideal wind percentage falls to 27%. Moist southeast flow brings the wettest month of the year at 3.11 mm/day; air temps sit near 22.6°C (18.1-26.1°C) and water at 23.7°C. March is a transition month: winter swells are still large but shadowed, while the south swell season has not truly arrived.
