March: Consistent Size with a Spring Shift
March remains a solid winter surf month, though the ocean is starting to transition. Average swell height is 2.4m (7.9ft) and the average period is still a respectable 12.1s. The swell direction is again locked into the NNW/NW corridor, with NNW at 23.3 percent, NW at 14.4 percent and WNW at 7.9 percent. Most waves fall in the 1.5-2.5m (5-8ft) category, giving Contreiras consistent stand-up size with occasional larger sets. Wind patterns are mixed: NNE and NE flows combine for nearly 38 percent, but west and southwest winds become more frequent than in January or February. The SSW-SW-WSW-W offshore sector is active enough to keep the ideal wind figure near 16 percent, and these can be very good when a low sits off the Galician coast and drags a westerly wind across the region. Air temperatures run from 12.4-21.1°C, water is 17.7°C, and precipitation averages 1.17mm/day. March rewards surfers who can read the weather charts and find the brief offshore windows between frontal passages.
