March: Southwest Energy and the First Splits

March nudges the average swell height up to 1.0m (3.5ft) with a period of 12.5s, and the dominance of WSW swells (43%) with SW (18%) trailing behind tells the story: the North Pacific storm track is still active enough to send combos that line up on the pier. W is 33%, so the mix is heavily oversized and wally for Huntington. The wave height distribution shows a greater share of 1-1.5m (3-5ft) broken lines (WSW 8.9%, W 13.7%), and even some 1.5-2m (5-6ft) from the W. But the wind forecast is the big change: ideal offshore flow drops to 28%, and the onshore SW/WSW component now dominates (44%), especially in the 10-20kph range. This means classic clean winter mornings become less frequent, but when a storm system passes and the offshore NE kicks in, March can offer some of the best, most powerful waves of the season. Air temps warm slightly to 14.7°C (58.5°F), rain eases to 1.59 mm/day, and the water remains a consistent 14.2°C (57.6°F).
