Green Spain is the name given to the northern strip of land between the Bay of Biscay and the Cantabrian Mountains in northern Spain. It's called green because it has a wet and moderate oceanic climate, strongly influenced by the Atlantic Ocean winds that get trapped by the mountains. The southern slopes get inside the rain shadow and the green Spain contrasts with its dry central plateau. The average precipitation is about 1,200 mm, this allows the lush vegetation to grow. Green Spain is considered to be formed by the regions of Galicia, Asturias, Cantabria and the Basque Country. The Pyrenees, that sometimes are considered to be united with the Cantabrian Mountains, use to be included in Green Spain.
