Conditions at Oyambre in March
March: The Last Big Punch of Winter
March is a true transition month. Average swell height is 1.8m (5-6ft) and period is 12.0s, so the ocean has not yet lost its winter body. The approach direction is almost perfect: 42.3% from the NW, 16.6% from the NNW and 14.9% from the WNW. This creates a really solid base of primary NW swell, with plenty of 1.5-2.5m (5-8ft) sets early in the month. By late March, though, the gaps between Atlantic low pressures start to grow.
Ideal offshore wind is present 34% of the time and an increasing amount of ENE/E wind (9.5% and 9.1%) begins to take over, especially in the afternoon. These easterly directions are not your friends at Oyambre - they add cross-shore texture and chop. Water temp is still cold at 12.9°C, air temp averages 11.3°C, and rain remains common at 2.62 mm/day. Early mornings and south-wind days are the golden tickets in March.
