Conditions at Troia in March
March: Late-Winter Groundswell with Changing Winds
March is still firmly in surf season, though the engine begins to weaken. Average swell height eases to 5.5ft (1.7m), but the period holds at 12.4s, so waves still arrive with long-period power. WNW (31.9%) and NW (31.3%) remain the dominant directions, while true west swell grows to 13.6% - the best W component of the northern winter, offering good exposure at Troia's southwest-facing sandbars.
Wind becomes a little more fickle: ideal conditions clock in at 40%, and the NNW flow strengthens to 22.6%. Still, the offshore NNE/NE/ENE/E sector contributes about 24% of all wind, and when it coincides with a passing low's W/SW swell, March offers some of the best drainage barrels and long walls of the season. Air temperature averages 13.5°C, precipitation 1.72mm/day, water temp 15.0°C, so the mild trend is beginning.
