Conditions at Itacoatiara in March
March: Autumn Mix, First Signs of Power
As autumn takes hold, the South Atlantic begins to stir. The average wave height picks up to 4ft (1.2m) and the period jumps to 10.4s. Swell direction becomes more south-oriented: SSE dominates at 32.6%, S at 25.7%, SE at 27.1%, while ESE falls to 10.6%. SSW remains only 2.3%, so true optimal swell is still rare. The surf size is no longer tiny: the 3-5ft (1-1.5m) range makes up a huge portion, and there are early signs of 5-6.5ft (1.5-2m) sets, especially from the S direction. Wind quality drops slightly to 57% ideal, as ENE and E winds still rule at 20.7% and 17.1%, but SW and WSW combine for about 10%, giving the first taste of southerly windswell. With water at 23.1°C, air at 25.3°C, and moderate rain at 5.76 mm/day, March offers a solid stepping stone into winter.
