Conditions at Rosie's Bay in March
March: The Transition Begins
March signals the first subtle shift away from the winter peak, but there is still plenty of power in the water. The average swell height eases to 2.2m (7.2ft) with a period of 12.0s - still very much in the powerful long-period class. Swell direction is overwhelmingly favourable, with W (24.0%) and WSW (23.0%) sharing the honours, followed by SW (12.9%) and SSW (5.2%). That combination delivers a remarkable 65% of wave energy from the optimal sweet spot. The wind is still workable: ideal offshore flow clocks in at 39%, though ESE (13.3%) and SE (12.1%) winds share the stage with WNW (10.8%) and NW (8.3%), meaning you may have to pick your sessions more carefully. Air temperatures creep up to 6.0°C, water remains cold at 8.4°C, and precipitation drops to 6.9mm/day. The surf is still very much alive, but the consistency of winter is starting to fade.
