Conditions at Middleton in March

March: The Autumn Transition Begins

March signals the first serious step toward winter at Middleton. The average period lengthens to 11.9s and the swell rose consolidates around the SSW window at 64.2% - the highest concentration of any month - with SW at 21.6% and S at 10.6%. Groundswell regularly arrives in the punchy 1-1.5m (3.3-4.9ft) range (29.8% from SSW), and a solid 19.2% reaches the 1.5-2m (4.9-6.6ft) class. Even a modest 4-5ft day here carries real Southern Ocean power.

Wind quality begins to shift as inland heating weakens. Ideal offshore winds climb to 24%, the S wind drops to 14.1%, SSW to 8.6%, and while SSE (19.8%) still makes its presence felt, the pattern is moving in the right direction. Air temperatures step down to 18.8°C, water to 19.3°C, and rainfall edges up to 0.79 mm/day. It is the classic transitional month: summer still clings on, but the ocean is already whispering about the long-period, offshore-blown surf that awaits.
