A Mediterranean climate is a climate that has dry summers that are hot or warm as well as winters that are cool or mild with moderate or high rainfall. It includes the climate of much of the land near the Mediterranean Sea. Outside the Mediterranean, one can find this climate only in rather small areas. It is found in many places that are roughly between latitudes 30° to 45° north and south of the equator.
In the Köppen climate classification, it is split between hot-summer Mediterranean (Csa), warm-summer Mediterranean (Csb) and cool-summer Mediterranean (Csc). Examples of Csa are Rome, Lisbon and Adelaide. Examples of Csb are Porto, Cape Town and San Francisco. Csc only occurs at very high altitude.
Besides the Mediterranean Basin, regions which have a Mediterranean climate include the coastal areas of the Western United States, down to Los Angeles, the Western Cape in South Africa, central Chile, southern Western Australia and the coastal areas of South Australia.
