 Its narrow relief makes it have a microclimate different from the rest of the region, affected by an Atlantic climate.So, while in the bottom of the valley of Liébana a Mediterranean climate can be enjoyed, it shifts progressively as we ascend to a humid Atlantic climate until subalpine conditions are reached in the high peaks of Picos de Europa.The average annual temperatures are 28°C maximum and 8°C minimum, with a lower precipitation rate than in other Cantabrian zones (800 mm annually versus 1,000 to 1,200 mm of average in the region).
