March: Transitional Size and Strong Swell

March is the last true winter month and it still delivers. The average swell is 5.5ft (1.7m) with an average period of 12.4 seconds, so the raw power is still there. WNW and NW swells split the direction spectrum almost evenly, at 32 and 31 percent respectively, while W swell adds another 14 percent. The distribution stays heavily weighted in the 3-6ft (0.9-1.8m) range, with a generous share of 6-8ft (1.8-2.4m) waves. The main caveat is the wind: ideal surf windows drop to 43 percent as spring starts to stir, and NNW wind becomes even more dominant at 20 percent. Still, the combination of long-period groundswell and a cool 15.1°C ocean makes March a reliable month for solid, powerful surf.
