Conditions at Sao Lourenco in March
March: The Last Great Push of Core Winter
March is a transition month but still delivers serious surf. Average heights are 2.3m (7.5ft) with a long-period 12.3s average. The swell direction shifts slightly northward, with NW at 24.5 percent and WNW at 18.3 percent, while NNW contributes another 14.8 percent. This is a prime window for solid, powerful groundswell, especially in the first half of the month.
The main limiting factor is the wind. NNW winds blow 20.9 percent of the time and ideal offshore flow from the east-southeast quadrant drops to 18 percent. Expect a mix of epic sessions under offshore high pressure and lumpy, wind-affected days when the northerly flow takes over. Air temperatures climb slowly to 13.4°C and water sits at 14.7°C.
