|Three main climatic zones can be separated, according to geographical situation and orographic conditions:
- The Mediterranean climate, characterised by warm and dry summers. It is dominant in the peninsula, with two varieties: Csa and Csb according to the Köppen climate classification. The Csb Zone, with a more extreme climate, hotter in summer and colder in winter, extends to additional areas not typically associated with a Mediterranean climate, such as much of central and northern-central of Spain (e.g. Valladolid, Burgos, León).
- The semi-arid 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 the northern quarter of the country, especially in the region of Basque Country, Cantabria, Asturias and partly Galicia. In contrary to the Mediterranean climate, winter and summer temperatures are influenced by the ocean, and have no seasonal drought.
