Conditions at Guethary in January
January: Deep-Winter Atlantic Power
January is peak season at Guethary. The numbers show an average wave height around 6ft (1.8m) and a long 13.0s period, which is exactly the kind of powerful North Atlantic groundswell this NW-facing beach was built for. The swell window is firing: WNW delivers 42.7% of all waves, NW another 29.3%, and nearly 80% of everything comes from the W-to-NNW quadrant. Heights are packed into the 3-8ft (1-2.5m) range, with some 8ft+ sets lurking in the mix. This is a proper winter slab.
Wind is a big part of the appeal - ideal conditions occur 47% of the time, mostly when the flow turns offshore out of the SSW, SW, WSW and W sectors. That offshore component is what turns the Atlantic lines into clean, hollow beach peaks. The flip side is the W/NW wind sector, which can quickly shred the surface. With air temps near 9.1°C, water temps at 12.5°C and roughly 3.5mm/day of rain in the system, a hooded 4/3 and booties are essential. Pick the windows and Guethary will reward you with some of the best waves of the year.
