Conditions at Guethary in March
March: Winter Keeps Its Grip
March is still very much a winter surf month, but with a subtle spring undercurrent. The average wave height eases to 5ft (1.6m) and the period slides to 12.2s. Swell direction is beautifully balanced between WNW (40.3%) and NW (40.6%), with another 4.9% from NNW and 1.8% from W. That means the beach is rarely without waves, and the top end of the range still delivers heavy 5-8ft (1.5-2.5m) sets from the North Atlantic.
Wind quality takes a step backward: ideal wind only 35% of the time. The W/NW/NNW sectors become more present as frontal systems sweep through, making the surface lumpier than in midwinter. Water temp sits at 12.7°C and air at 10.7°C, so the water is still cold, but the longer days and occasional SSW/WSW offshore breeze make March a rewarding transition month for patient surfers.
