Conditions at Margaret River in March
March: The Long-Period Pulse Starts to Wake Up
March is a turning point. The average period climbs to 12.5s, the first sign that the Southern Ocean is waking from its summer nap, and average height remains at 1.9m (6.2ft). SW is still the dominant swell source at 38.4%, with SSW close behind at 27.3%, and there is a noticeable increase in the WSW/W component, adding more westerly push. The ideal wind percentage rises to 21% as E/ESE winds become a bit more common. This is also one of those transition months where a passing high pressure system can deliver a couple of consecutive days of clean offshore conditions between fronts. With water temps at 21.2°C, air around 20.0°C, and rainfall still modest at 0.79 mm/day, March is a sleeper month for good waves - often smaller, but smooth and welcoming.
