Conditions at Praia Grande in March
March: The Last Big Push
March is still excellent, even as spring begins to stir. Average wave height remains solid at 7.5ft (2.3m), with a strong average period of 12.3 seconds. The northwest quadrant dominates even more: NW is 24.5 percent, WNW 18.3 percent, NNW 14.8 percent, and W 6.4 percent. The Atlantic storm track is beginning to weaken, but the swells that arrive are often just as powerful as midwinter. The main change is in the wind. NNW flow becomes the clear leader at 23.5 percent, while N reaches 10.5 percent and NW 7.1 percent. Ideal offshore wind drops to 17 percent, so quality becomes more window-dependent. When a high-pressure cell drifts over the Iberian Peninsula, E/ESE/SE winds can still groom the faces, and those days are worth blocking out. Air temperatures average 13.4°C (min 0.0°C, max 24.3°C), precipitation is 1.77 mm/day, and water temperature is 14.7°C. March is a transition month with a winter heart.
