* The semi-arid climate (''BSk'', ''BSh''), is predominant in the southeastern quarter of the country, but is also widespread in other areas of Spain. It covers most of the Region of Murcia, southern Valencia and eastern Andalusia, where true hot desert climates also exist. Further to the north, it is predominant in the upper and mid reaches of the Ebro valley, which crosses southern Navarre, central Aragon and western Catalonia. It also is found in Madrid, Extremadura, Castilla-La Mancha, and some locations of western Andalusia. The dry season extends beyond the summer and average temperature depends on altitude and latitude.
