Conditions at Watergate Bay in March
March: The Changeover Month
March is the gateway between winter power and the spring transition. The average swell drops to 6ft (1.8m) but the period remains a meaty 11.5s, so there is still plenty of groundswell to go around. W is again the lead direction at 37.1%, with WNW and WSW adding important energy; together these quadrants keep the bay open to quality northwest Atlantic swell. The height distribution has shifted down slightly, with plenty of waves in the 3-6ft (1-2m) range and a smaller percentage in the overhead-plus category. Ideal winds remain at 23%, and spring often brings more variable, lighter winds than midwinter, especially late in the month. Air temperatures average 8.2°C, water temp is still cold at 9.0°C, and precipitation drops to 2.54mm/day. The surf is still serious, but the edges of each passing low are beginning to offer more manageable, cleaner sessions.
