Conditions at Niijima in March
March: The Spring Directional Shift Begins
March is a transition month and it shows. Swell heights hold at 1.7m (5-6ft) and period inches up to 7.4s, but the directional picture broadens. ENE remains the top optimal source at 14.5%, with E at 9.9%, ESE at 6.3%, and SE at 4.5% - a combined 40.1% from the ideal quadrant. West and WSW still chip in 12.4% and 9.5%, but the ocean is no longer purely a winter windsea; early-season Pacific lows along the subtropical front are starting to send more easterly energy.
Wind patterns become more variable. NE and ENE onshores total 19.8%, while offshore W and WNW take 13.7% and 11.1%; WSW adds 9.6%. This makes for a 12% ideal wind month, but the quality of the ideal windows improves because the winds are less extreme. A light W/NW morning breeze with 2-4ft (0.6-1.2m) ESE-E swell is a classic March scenario, and as the month progresses, the increasing water temperature (18.0C) and air temps near 13.1C bring longer, more comfortable sessions. Rainfall climbs to 5.49 mm/day, a sign of the stormier spring transition.
