Conditions at Nazare in March
March: Big Swell with a Spring Edge
March holds onto winter's energy while the days start to lengthen. Average swell height eases only slightly to 7ft (2.1m), and the average period is still a strong 12.4 seconds. NW swell now leads the pack at 27.6 percent, followed closely by WNW at 23.0 percent; NNW contributes 10.9 percent and W 7.7 percent. The mix is slightly more north than midwinter, so there are still plenty of solid waves, but quality improves when the direction backs into the W/WNW window. Offshore wind is ideal 44 percent of the time, with NNW again the most frequent single wind direction at 24.7 percent. That makes morning or synoptic easterly windows especially valuable. Water temperature is 14.3°C and air temps average 13.5°C, so expect cool but increasingly pleasant surf days, with rain easing to 1.92 mm/day.
