Conditions at Alvor in March
March: Spring Transition and Wrapping NW Swells
March still offers a solid 1.3m (4.2ft) average with a 12.1s period, so the winter engine is not quite done. The wave rose stays west-heavy - WNW 28.5 percent, NW 26.6 percent, and W 14.2 percent - while direct SSW and SW swell remain limited at 1.4 and 2.3 percent respectively. Ideal wind drops slightly to 35 percent, with NNW at 21.6 percent and NW at 10.6 percent providing the cleanest windows. Air temperatures warm to 14.8°C, water holds at 15.6°C, and rainfall is still substantial at 2.00mm/day. The increasing sun and instability mean daytime sea breezes arrive earlier, so surfers should target the morning hours following an overnight offshore flow. When a late-season Atlantic low sends a 13-15s SW swell and the wind goes N/NE, March can fire off as well as any midwinter month, especially on the mid-to-high tide sandbars.
