Conditions at Aramoana in March
March: Autumn's First Big Pulses
March is where autumn begins to flex. Average wave height jumps to 6-7ft (2.0m) and the average period reaches 11.2s, signalling more distant, organised Southern Ocean groundswell. However, the dominant swell direction shifts further toward SSW and SW, making the NE-facing zones less consistent. ENE and NE still contribute around 13% of wave energy, and ideal wind time sits at 24%. Winds are split between fresh NNE onshores and strong WSW/SW offshores, so conditions change quickly with each passing front. Air temps average 13.0°C, water temp has eased to 13.8°C, and precipitation drops to 1.78 mm/day. Look for days when a high-pressure ridge stalls after a front; those offer cleaner NE wrapping swell and much better shape.
