Cantabria is an autonomous community in northern Spain bordering the Cantabrian Sea (Bay of Biscay), celebrated for its rugged Atlantic coastline, prehistoric cave art at Altamira, soaring Picos de Europa peaks, and a cuisine centred on fresh seafood and aged cheeses.

Cantabria has an oceanic climate (Köppen Cfb) heavily influenced by the Bay of Biscay. Summers are warm and relatively sunny (18–25°C); winters mild but wet. Rain falls year-round — annual average in Santander is 1,200 mm — with the wettest months being November to February. The Picos de Europa create a dramatic rain shadow; southern Cantabria and the Liébana valley are significantly drier and warmer in summer.
