Conditions at Little Wanganui in March
March: The Autumn Engine Starts to Turn
March is where the season starts to feel real. Average swell height holds at 5-6ft (1.5-1.8m), but the average period climbs to 12.3s, and the first serious autumn lows begin to spin up in the Tasman Sea. The swell rose still shows a heavy bias toward WSW (56.0%) and W (15.5%), but the proportion of mid-sized 1.5-2.5m swell grows, and the longer period means those waves wrap and stand up better along the beach.
Conditions become more favourable for clean surf, with ideal offshore winds rising to 39 percent. ESE and SE winds are the go-to, and they appear frequently enough to give several quality windows each month. With water temperature at 17.1°C and air averaging 15.0°C, it is still pleasant, but the crisp mornings hint at autumn. If you see a strong cold front pushing through the Tasman, March is capable of producing pumping 8ft (2.4m) waves with near-perfect offshore wind.
