The climate of Spain is mainly Mediterranean. It is marked by variations of temperature and, except in the north, generally insufficient rainfall. The variegated physical features of the country ensure pronounced climatic differences. The climate is most equable along the Biscayan and Atlantic coasts, which are generally damp and cool. The central plateau has summers so arid that nearly all the streams dry up, the earth parches, and drought is common.
Most of Spain receives less than 610 mm (24 in) of precipitation per year; the northern mountains get considerably more moisture. Around Madrid, winter cold is sufficient to freeze surrounding streams, while summer temperatures rise as high as 41.7° C (107° F). By contrast the southern Mediterranean coast has a subtropical climate. Málaga, in the extreme south, has an average winter temperature of 13.9° C (57° F).
