Conditions at Areia Branca in March
March: Powerful Swell as Spring Teases
March is still prime time at Areia Branca. Average wave height drops a bit to 7.5ft (2.3m) but period remains a solid 12.3 seconds. The NW sector is the clear standout, with WNW also well represented; the swell is slightly less focused than midwinter but no less powerful. Areia Branca's west-facing exposures still see plenty of proper, mid-to-long-period groundswell, and there will be days when March serves up surf that rivals January and February.
The trade-off is wind. Ideal offshore conditions fall to 30 percent as the continent starts to warm and pressure gradients tighten. NNW winds are the dominant signal at 23.3 percent, creating more cross-onshore texture between events. Air temps warm slightly to 13.5°C, rainfall eases to 1.92 mm/day, and the water remains cold at 14.5°C. The windows of offshore flow are still worth chasing; a March dawn patrol with light E wind and a solid NW swell is hard to beat.
