Conditions at Ferrugem in March
March: Autumn Stirrings
March marks the first real shift away from summer. Average period nudges up to 8.6s, ideal surf wind reaches 47%, and the swell distribution becomes more ESE/SE dominant: ESE 28.6%, SE 21.0%, E 22.6% and ENE 9.5%. This is excellent directional alignment for Ferrugem. Average height is still 4ft (1.2m), but the percentage of 5-6ft (1.5-2m) waves increases, especially from the ESE and SE sectors. Air temperature cools to 22.8°C, water temperature stays warm at 25.2°C, and rainfall eases to 4.65 mm/day.
Wind patterns become more meridional as the first autumn cold fronts arrive. NNE is still the leading direction at 14.3%, but SSW (9.3%) and SW (6.6%) are on the rise, and the offshore W/WNW quadrant has a stronger presence. These pre-frontal and post-frontal W/NW windows offer the cleanest sessions of the month. March is a shoulder month that mixes fun small waves with the first hints of real Southern Ocean power.
