Conditions at Cova da Alfarroba in March
March: Spring Transition, Still Firing
March signals the start of meteorological spring but the surf still has winter muscle. Average swell height eases slightly to 8ft (2.5m), with a 12.4-second period - still very much in the powerful long-period range. The swell direction is even more focused: NW (21%) and WNW (16%) dominate, with NNW (14%) close behind. On the wind side, northerly flow strengthens; NNW (23%) and N (10%) are the leading directions, and ideal S/SSW/SW winds drop to 21%. The good news is that frontal systems still track across the North Atlantic in March, offering periodic south winds ahead of the front and big, clean NW swell. Average air temps rise to 13.5°C and water holds at 14.4°C, so conditions are still all winter. It's a great month for the surfer who doesn't mind checking the forecast every day.
