The Mediterranean climate

The Mediterranean climate is characterized by dry and warm summers. According to the Köppen climate classification

, it is dominant in the peninsula, with two varieties:

The typical Mediterranean climate (Csa climate) is present in the most of the country. Like the other Mediterranean regions, the annual rainfall is 300 to 700 mm (11.8 to 27.6 in); most of the Meseta region receives about 500 mm (19.7 in). The northern Meseta, the Sistema Central

, and the Ebro Basin have two rainy seasons, one in spring (April–June) and the other in autumn (October–November), with late spring being the wettest time of the year. In the southern Meseta also, the wet seasons are spring and autumn, but the spring one is earlier (March), and autumn is the wetter season. Even during the wet seasons, rain is irregular and unreliable. Summers are warm and cloudless, producing average daytime temperatures that reach 21 °C (69.8 °F) in the northern Meseta and 24 °C (75.2 °F) to 27 °C (80.6 °F) in the southern Meseta; nighttime temperatures range from 7 °C (44.6 °F) to 10 °C (50 °F).

Some Spanish authors want to distinguish an "inland" variant of this climate (sometimes called "continentalized" Mediterranean climate) which has lower temperatures in winter than the coastal areas (mean temperature in January about 6 °C (42.8 °F) in Madrid , 11.5 °C (52.7 °F) in Valencia). This distinction is rather a local nuance which does not appear in the world academic classifications.

The rainfall is generally abundant, exceeding 1000 mm (39.4 in) and is fairly evenly spread out over the year, with the driest month above 30 mm (1.2 in), which is the minimum criteria for an oceanic climate according to Köppen.

 prefer to extend this climatic zone to the north-west part of the peninsula to Galicia, due to the moderate summer temperatures.

Temperatures vary only slightly, both on a diurnal and a seasonal basis, averages range from 9 °C (48.2 °F) in January to 21 °C (69.8 °F) in July. The moderating effects of the sea, however, abate in the inland areas, where temperatures are more extreme than temperatures on the coast. Distance from the Atlantic Ocean also affects precipitation, and there is less rainfall in the east than in the west. Autumn (October through December) is the wettest season, while July is the driest month. The high humidity and the prevailing off-shore winds make fog and mist common along the northwest coast, this phenomenon is less frequent a short distance inland, however, because the mountains form a barrier keeping out the sea moisture.

, characterized by year-round mild temperatures, with summers months which are usually dry, often resulting in moderate drought conditions, with one month per year usually accounting less than 40 mm (1.6 in), characteristic that takes it away from a typical Cfb climate, while the rest of the seasons are generally rainy: the annual rainfall is higher than in other regions, usually ranging from 800 to 2000 mm (31.5 to 78.7 in). This climate, which is sometimes classified as "Mediterranean", is classified as "Oceanic" according to other authors like Trewartha, due to the lower summer temperatures and higher rainfall. Nevertheless, the area has typical Mediterranean features, including the regular forest fires, which anyway are caused frequently by arsonists. Galicia keeps a high level of annual sunshine duration, ranging from 1800 hours in the northeast to 2200 in the southwest.

In North-West Castilla, the climate is classified also as Csb because the temperatures of summer are less hot due to the altitude.

) can be found in the South-eastern part of Spain (covering most of Alicante, Murcia and Almería provinces), in some areas of the Ebro Valley too. Very hot in summer (temperatures can exceed 40 °C (104 °F), the drought extends beyond the summer (rainfall about 300 m - ). Very dry, virtually sub-desertic, rainfall as low as 120 mm (4.7 in) a year in the Cabo de Gata which is reported to be the driest place in Europe.
