Conditions at Ericeira in March
March: The Last Big Push
March is the final month of true winter consistency. The average swell is still 2.3m (7.5ft) with a period of 12.3s, and NW direction dominates, while WNW and NNW remain strong. Even though the storm track is starting to retreat, March often delivers classic pre-spring groundswell with lighter winds than midwinter. Ideal offshore flow from the NE through ESE is present 20% of the time, and the arrival of slightly warmer air - averages around 13.4°C - makes those clean sessions much more comfortable. Water temperature is a cool 14.7°C. Rain totals drop a bit, too, but don't be fooled: the Atlantic can still throw a heavy, stormy westerly swell your way at any moment. Stay ready for pumping days with offshore easterlies, and you'll find some of the most underrated waves of the year.
