Conditions at Whangapoua Beach in March
March: Autumn's First Consolidation
March holds onto the summer swell axis while autumn begins to stir. The average period reaches 8.1s - tied for the highest of the year - which adds a touch of punch even though the average height remains 1.5ft (0.5m). The N-NNE-NE-ENE window still delivers 51% of the swell; ENE accounts for 26% and NE another 16%, with E swell adding 15%. The directional foundation is solid, but the wave height distribution remains small, with most energy under 1m.
Wind patterns start to become more energetic. SW at 12.1% and WSW at 10.7% make up the core offshore flow, around 30% all up, but onshore N-NE winds still account for 20%. Ideal conditions arrive just 1% of the time, so don't expect a glassy morning to last long. Air temperature is 19.4°C, the water is 20.7°C, and rainfall ticks up to 2.29mm/day as the first winter lows probe the Tasman Sea. Chasing a clean NE-ENE pulse under a morning WSW breeze is the name of the game.
