Conditions at Brandon Bay in March
March: Spring Swell With Winter Punch
March is a transition month, but the ocean is still in winter mode. Average swell is 5ft (1.6m) at 12.0 seconds, which remains firmly in the powerful long-period category. The waverose is stacked with WNW (28.7%), W (25.1%), WSW (12.8%) and NW (11.7%) - a continuous conveyor belt of westerly energy. WNW is a touch north of ideal, but its long period wraps effectively into the bay and produces clean, well-shaped peaks on the right tide. The wind pattern is easing: onshore SSW, SW, WSW and W drop to around 37 percent, while ideal offshore flow increases to 27 percent, the best since December. That means more frequent clean windows. Water temperature is 8.7°C and climbing, air averages 8.0°C, and precipitation is 3.10 mm/day. By late March you will start to enjoy the first proper, sparkly spring surf sessions.
