March: The First Hint of Southern Ocean Muscle
March marks the transition toward the stormier half of the year, and you can feel it in the numbers. The average swell remains 8ft (2.5m), but the period lengthens to 11.4s, and the SSW wave direction (18.3%) is backed by more S and SW energy. The E-ESE-SE-SSE window is still healthy at around 18 percent, keeping the spot open to some nice ESE/SE groundswell as autumn settles in.
Winds begin to improve, with offshore W/WNW/NW/NNW flow up to 23 percent of the time and ideal surf wind at 25 percent. The E/ESE onshore flow is still significant - E 17.6%, ENE 14.7% - but it is less relentless than midsummer. Air temps ease to 20.7°C and water temp drops to 19.0°C. March often rewards surfers who are patient, as the cleanest waves come on the back of the first true west wind of autumn.
