Conditions at Agua d'Alto in March
March: The Last Big Swell Month
March averages 2.5m (8ft) of swell at 11.8s, so the beach is still very much in winter surf mode. The direction statistics are again dominated by NNW (13.2%) and NW (9.4%), with a healthy WNW (8.9%) contribution. The magic SSW-SW sector remains a minority, but when it shows up-especially as a WSW swell-it is exactly what Agua d'Alto needs to form hollow, lined-up waves. Heights sit mostly in the 1.5-2.5m (5-8ft) range, with the occasional bigger set.
Ideal N to ENE offshore winds clock in around 25% of the time, while SW, WSW and SSW onshore winds still combine for over 25%. March can be fickle, but the period is still 11.8s-plenty of power when the conditions align. Air temperatures average 15.4°C, water temperature has cooled to 15.9°C, and precipitation is 1.94 mm/day.
