Conditions at Santa Catarina in March
March: Winter Energy With a Spring Twist
March begins to loosen winter's grip, but Santa Catarina still sees serious surf. Average open-ocean swell height drops only slightly to 9ft (2.8m), and the average period remains a respectable 11.7s. The wave rose is led by NNW at 10.7%, NW at 8.7% and WNW at 7.5%, alongside an elevated NNE component of 4.2%, meaning a bit more of the swell is aimed directly at the north-east-facing sandbar. The wind picture is still winter-like, with SW at 10.9%, WSW at 8.9% and SSW at 8.6% the most common offshore directions, but ideal conditions are limited to 12% due to stronger pressure gradients. When N through E onshore winds are not blowing, expect punchy, powerful surf with occasional well-overhead days. Air and water temps stay cool at 15.3°C (59°F) and 15.5°C (60°F), but the first true spring sunshine often appears between frontal systems.
