Conditions at 13th Beach in March
March: The Autumn Transition Begins
March is the first real sign of the winter swell machine stirring. Average period jumps to 11.9s, and ideal offshore wind frequencies climb to 18% - still not spectacular, but noticeably better than January and February. The onshore SSE-SW flow drops to around 42% of the wind rose, while the N, NNE, NE and NNW offshore window expands to just under 15%. Swell direction shows a clear dominance from the SW (44%) and SSW (28%), with a healthy chunk of waves in the 3-5ft (1-1.5m) and 5-6.5ft (1.5-2m) bins. Average wave height sits at 5ft (1.5m), but there are increasing numbers of 6.5-8ft (2-2.5m) pulses as Southern Ocean lows start to intensify. With water temp still comfortable at 19.6°C and air temps averaging 17.5°C, March offers good surfing if you can pick off the cleaner windows during a lull in the seabreeze.
