Conditions at Sosua in March
March: Spring Steadiness Before the Lull
March is the last true winter month at Sosua, and the numbers reflect a spot still holding onto its best windows. Average swell height is 4.9ft (1.5m), average period is 9.4s, and the ideal N/NNE/NNW directions combine for 21% of the wave rose - one of the highest contributions of the year. ENE swell still leads the pack at 37%, with NE at 27%, so the vibe is a mix of wrapping trade swell and more direct north energy. Winds are favorable 31% of the time; the E/ESE trades remain the dominant player but often lighten in the morning, creating a clean dawn window. Water temp is 26.0°C, air temps average 24.7°C, and precipitation is low at 1.3mm/day. Treat March as a bonus month to stack quality sessions before the late-spring lull.
