Conditions at Murtosa in March
March: Spring Punch and Shifting Winds
March is still a serious surf month, but the seasonal gears start to turn. Average swell height is 2.3m (7.5ft) and the average period remains respectable at 12.2s. Swell direction is actually even more optimal than midwinter: NW leads with 23.2%, WNW follows at 20.9%, and W/WSW add another 10.5%, meaning the beach gets plenty of full-exposure groundswell. Heights are concentrated in the 1.5-2.5m (5-8.2ft) range, so good-sized waves are the rule rather than the exception. The issue is wind. The ideal-window frequency drops to 37% as the Azores High builds and NNW winds climb to 20.2% of all observations. Those north winds create bumpy, cross-onshore conditions and shorten the clean windows, but when an E/ESE offshore flow sets up, Murtosa can still deliver excellent, hollow waves. Air temperatures warm to 12.5°C, rainfall averages 2.63 mm/day, and water temperature starts to climb at 13.9°C.
