Conditions at Paul do Mar in March
March: Late-Winter Muscle Shifts
March keeps the winter energy alive, but the seasonal transition becomes visible. Average swell height is still a healthy 2.4m (8ft), while the average period slips slightly to 12.1s. The wave rose still tilts hard to the north, with NNW at 23.3% and NW at 14.4%, but there is more spread into the W (1.7%) and WSW (0.4%) than in deep winter. The wind becomes the weak link: ideal offshore conditions drop to 37%, the lowest of the cold season, as lows begin to track closer to the island. That means more variable, onshore SW-to-NW winds and a slightly lower hit rate at Paul do Mar. Still, a couple of days each week will deliver clean, long-period groundswell, and the water temp holds at 17.9°C while air temps average 16.9°C (12.7-20.2°C). Rain averages 1.17mm/day.
