March: Winter Power with a Spring Twist
March remains in the picture as a high-quality surf month. Average swell height is still 6.9ft (2.1m) and the 12.0s period keeps the energy lined up. The wave rose shows the same NNW/NW dominance-NNW at 38.8%, NW at 18.1%-so the beach continues to receive consistent, powerful ground swell. The first signs of spring appear in the wind stats: NNE flow builds to 30.0% and ideal wind conditions drop to 19%, meaning you have to be a little more selective. Still, the middle of March often produces some of the last proper W/NW long-period swells before the summer lull. Air temperatures rise slightly to 18.0°C, water holds at 18.6°C, and rainfall drops to 0.36mm/day, making the shoulder-season surf very appealing.
