Conditions at Andran in January
January: Deep-Winter Authority
January is the most reliable month of the year at Andran, and the numbers underline it. The average swell height sits at 1.9m (6ft) with a 12.7s period, giving the beach a constant supply of long-period, high-energy groundswell. The western half of the swell window dominates: NW accounts for roughly 41% of all recorded swell, with WNW adding 14% and NNW another 13%. Those are exactly the directions that wrap into Andran's exposed corner of the Cantabrian coast and produce the heaviest, most organised waves of the season.
The wind stats are equally kind. The wind is ideal for surfing 46% of the time, the highest annual figure, largely thanks to more frequent S, SSW and SW flow accompanying winter low-pressure systems. N/NNW/NW/WNW winds, by contrast, ruin the quality, so patience is still needed at times. Air temperatures average just 9.5°C, precipitation runs around 3.3mm/day and the water drops to 13.5°C, so this is serious winter surfing - suit up in a thick set and you'll reap the rewards.
