Three main climatic zones can be separated, according to geographical situation and orographic conditions:
• The Mediterranean climate, characterized by dry and warm summers. According to the Köppen climate classification, it is dominant in the peninsula, with two varieties: Csa and Csb. The Köppen-Geiger classification (Csb), extends to additional areas not typically associated with a typical Mediterranean climate, with a climate more extreme, hot in summer and cold in winter, such as much of central and northern-central of Spain (Ex. Madrid, Burgos, Leon).
• The semiarid climate (Bsh, Bsk), located in the southeastern quarter of the country, especially in the region of Murcia and in the Ebro valley. In contrast with the Mediterranean climate, the dry season extends beyond the summer.
• The oceanic climate (Cfb), located in north quarter of the country, especially in the region of Basque Country, Asturias, Cantabria and partly Galicia. In contrary to the Mediterranean climate, winter and summer temperatures are influenced by the ocean, and have no seasonal drought.
Apart from these main types, other sub-types can be found, like the alpine climate in the Pyrenees and Sierra Nevada, and a typical subtropical climate in the Canary Islands
