Andorra is a tiny independent principality, high in the eastern Pyrenees on the border between France and Spain. Lying on the southern or Spanish side of the crest line, it is rather sheltered and therefore drier than much of the French Pyrenees. The whole country lies above 840 meters (2,750 feet).
Andorra has a temperate (moderate) climate, but the winters are cold but rather dry and sunny. Snow completely fills the northern valleys for several months. The midsummer months are slightly drier than spring and autumn and, with the cool temperatures, summer is a pleasant season. Summers are generally warm and dry. More of the country's rainfall occurs from April to October than in the winter months.
The capital, Andorra la Vella, is representative of the valleys in this small state. Temperatures are lower in the higher mountainous area.
