Conditions at Supertubos in March
March: Late-Winter Power with a Hint of Spring
March still feels like winter when it comes to surf. Average swell height is 8.2ft (2.5m) and the period remains solid at 12.4s. The dominant swell directions shift slightly more north: NW (21.2%), WNW (16.3%), and NNW (13.5%) mix to produce consistent, head-high-plus waves. The wave-height distribution skews heavily into the 1.5-2.5m classes, with some of the bigger days pushing past 2.5m. Offshore wind potential remains solid at 38%, though the spring transition begins to bring more days of cross-shore NNW wind, which can add a bit of texture. The warm air masses are still relatively rare - average high temperatures barely top 23°C - but the water is 14.4°C, so a thick wetsuit is still required. March is the last month to catch the true monster winter swells before the Pacific-like energy begins to fade.
