March: Spring Swell Mix, Still Plenty of Power
March marks the transition toward spring but the surf stays big. Average height holds at 1.1m (3.5ft), with an 11.8s period. The dominant west (47 percent) and west-southwest (30 percent) swells are joined by a stronger southwest component (12 percent), giving Point Dume a nice mix of wrap-around west groundswell and more direct southwesterly lines. The standout feature is size: a much larger share of swell sits in the 3-5ft (1-1.5m) range, and west pulses can reach 5-8ft (1.5-2.5m). Wind becomes a little less consistent with 60 percent ideal conditions, as afternoon westerlies pick up with the warming ocean. Air temperatures rise to 14.4°C (58°F), rainfall drops to 2.28 mm/day, and water temps fall slightly to 13.6°C (56°F) with spring upwelling. Overall, March remains one of the best months for solid, long-period surf.
