Conditions at Sopelana in March
March: High Energy with a Hint of Spring
March remains firmly in the best surf season, though the average swell eases slightly to 1.8m (6ft) with a period of 12.1s. The direction is even more NW-dominant - NW alone accounts for a massive 40% of all swell, with WNW adding another 20%. The Atlantic storm track is still firing, pushing long-period energy straight into Sopelana's bight. Ideal winds occur 31% of the time, and the relatively frequent S/SSW winds help groom the larger groundswell into clean, rippable walls. Air temperatures are warming, averaging 11.3°C, while the water holds near 12.8°C. If you time the tides between frontal passages, March can produce some of the best tubes and heaviest sessions of the entire season.
