Conditions at Porto Covo in March
March: Last Big Push Before Spring
March is the final solid month of meteorological winter, and the transition to spring is visible in the numbers. Average swell height drops slightly to 7ft (2.1m), while the period remains a powerful 12.4s. The direction mix is excellent: NW (30%), WNW (23%) and W (8%) combine for over 60% of the total swell, so Porto Covo continues to catch substantial Atlantic groundswell. The wind becomes the limiting factor: ideal offshore flow slips to 34%, while NNW (22%) and NW (9%) winds add chop, especially in the afternoon. Early mornings and days with an east-northeast (ONO) breeze are the go-to. Water temperature climbs to 15.2°C, air temperature to 13.6°C, and rainfall is similar at 1.65mm/day. Spring instability can still throw plenty of surf at this coastline.
