March: Transition Month with Quality WNW Favoring Perranporth

March is a transition month in the North Atlantic, and Perranporth feels it in the averages: swell height drops to a still-respectable 6ft (1.8m) and average period eases to 11.5s. The direction mix becomes even more favorable, with W at 37.1%, WNW 15.9% and WSW 13.6% - together over 66% from the optimal westerly band. The WNW component is especially good news for this west-northwest-facing beach, as it aligns more directly with the coast and often produces better-lined-up waves. A lot of the swell arrives in the 1.5-2m (5-6ft) range, with enough overhead days to keep it interesting. Offshore flow improves slightly to 20%, and the lighter precipitation totals (2.54mm/day) hint at spring. Water temperature is still cold at 9.0°C and air temps hover around 8.2°C, so a hood and boots are still standard, but the increasing frequency of clean, offshore spring days makes March a favorite for winter-weary surfers.
