March: Autumn Transition Opens the Door
March is where Jan Juc starts to turn the corner. Swell height remains steady at about 5ft (1.5m), but the average period jumps to 11.9s, and the ideal wind window expands to 26%. The swell direction is still overwhelmingly SW (43.9%) and SSW (28.4%), with S/SSE/SE adding another 14%. With the longer periods and these south-of-west directions, the Southern Ocean groundswell is starting to have more punch when it reaches the coast.
The wind picture is transitioning too. The percentage of SE/SSE onshore breezes drops from summer levels, while W, WSW, WNW and NW directions become more common. That means more cross-offshore and offshore conditions, especially on the back side of winter cold fronts. Air temperatures are still pleasant at 17.5°C, water temperature is a warm 18.9°C, and rainfall is the lowest of the year at 1.34mm/day. March is a solid month for quality waves with plenty of morning windows.
