Conditions at Malhao in March
March: Last Big Push of Winter Before Spring Transition
March remains a serious surf month. Average swell height is 2.1m (7ft), average period is 12.4s, and the swell direction now tips even more toward NW, which makes up 30.2% of all observations. WNW adds another 23.1%, with W at 8.0%, keeping Malhao well exposed to the dominant Atlantic energy. Most of the waves fall in the 1.5-2.5m (5-8ft) range, so there is plenty of size to push through the sandbars. Ideal wind drops to 34% as the spring nortada begins to stir: NNW winds dominate at 21.8%, and NW winds add 9.0%. These winds can put a bump on the surface, so look for lighter mornings or the arrival of an easterly offshore flow. Air temp averages 13.6°C, precipitation is 1.65 mm/day, and water temp sits at 15.2°C. March offers one last taste of winter severity before the ocean softens.
