March: The Transition Tightens
March is a classic shoulder-to-winter month. Average swell height eases to 5ft (1.6m), but the period remains a powerful 12.2s. Directionally, it is hard to beat: WNW 40.3 percent, NW 40.6 percent, NNW 4.9 percent - over 85 percent from the ideal NW/WNW window. The height distribution still contains plenty of 5-8ft (1.5-2.5m) surf, though the 2-3ft (0.5-1m) range is beginning to grow.
The wind is ideal 36 percent of the time, a step down from midwinter. WNW (10.6 percent), NNW (10.0 percent), W (11.2 percent) and NW (8.5 percent) show the increasing influence of spring sea breezes and trailing cold fronts. Offshore S/SSW/SW/WSW flow still appears regularly, but windows become more localized. Water temps hold at 12.7°C and air temps creep up to 9.8°C. Good winter waves are still available if you are selective.
