March: Spring Storm Energy
March is a transition month, but the winter storm track still fires. Average swell height ties the seasonal peak at 1.4m (4.6ft), while the average period ticks up to 7.5s, adding a little more push. S swells lead the pack at 12%, with strong contributions from ENE (11.5%) and E (10.9%); the favorable ESE-S sector accounts for 36% of the total. Winds are more variable than in February: WNW is still the top direction (11.8%), but SSW has become close behind at 10.0%, and the 'ideal wind' percentage drops to 24%. That means more days with onshore or side-shore flow, but the good days are excellent. Water temp remains cold at 5.6°C (42°F) and air temps average 5.2°C (41°F). Precipitation is the highest of the year so far at 3.72 mm/day, driven by vigorous spring fronts.
