Conditions at Punta Arena in March
March: Southern Groundswell Starts to Gatecrash
March marks a clear shift in the swell spectrum. The average period climbs to 12.7s, giving more of that long-period push, but the direction becomes even more southerly. S swell now dominates at 39.3%, with SSE at 11.4%, SSW at 12.5%, and SW close behind, while NNW still contributes 17.1%. The preferred NE, ENE, E and ESE directions together account for less than 1% of the wave observations, so Punta Arena increasingly relies on deflection and wrap rather than direct exposure.
Air temperatures warm to around 21.7°C and water stays at 21.4°C, while precipitation is almost negligible at 0.04 mm/day. The ideal wind percentage holds at 42%, with light W and WNW offshore flow offering clean, mostly glassy mornings. The result is small-scale but lined-up surf, often in the 2-3ft (0.6-0.9m) range, with the occasional 3ft set when a longer-period southern pulse pushes through.
