Csak Subtropical climate with dry summer with hot summer with cool winter
Traditional Koppen classification: Csa (Hot-summer Mediterranean climate)

Official definition:
  • C – temperature of warmest month greater than or equal to 10 °C and temperature of coldest month less than 18 °C, but higher than -3 °C
  • s – precipitation in the driest month during the summer half year is less than 30 mm and less than one third of the precipitation in the month with highest precipitation in the winter half year.
  • a - temperature of the warmest month is higher than 22 °C

Cs climate type is characterized by a dry summer and wet winter. In the case of the Csa subtype, the summer tends to be very warm. The average temperature of the warmest month is above 22 °C. The wettest month in the winter usually has three times as much precipitation than the driest month in the summer, which usually has less than 30 mm of rainfall. Summers are therefore quite dry, with relatively little cloudiness and often longer periods with no rain at all. Winters on the other hand are wet and very rarely it snows as well.

Temperatures in the summer reach very high values between 30 and 40 °C. In the winter it is very unusual for the temperatures to fall below freezing point.

The continental Mediterranean climate (Csa) is sometimes also referred to as hot Mediterranean climate. The higher temperatures are the result of the fact that the places are usually deeper inland. The Csa subtype is more common than the other Cs climates and usually represents what most people imagine under the term “Mediterranean climate”.

It can be found for example around the Mediterranean sea in Europe, in Southwest Australia, Southwestern part of South Africa, some parts in Central Asia and in Northern California. Other places also include some microregions such as the Spanish capital Madrid, Italian Rome, American Los Angeles or Perth in Australia.


Modern Trewartha classification: Csak (Subtropical climate with dry summer with hot summer with cool winter)

Subtropical in the Koppen and Trewartha classification is defined as a region, where at least eight months has an average temperature of more than 10 °C, but the coldest month has an average temperature of less than 18 °C. The individual subtypes then differ in their annual precipitation distribution. In Trewartha classification there is a condition of maximum annual precipitation of 900 mm.

In general the subtropical climate is usually found in areas polewards from the tropical zones. It can also be found inside tropical zones at places with higher altitude. Typical are for example citrus trees or palm trees.

The Cs subtype in the Trewartha classification represents a subtropical climate with dry summer, sometimes referred to as the Mediterranean climate. It is characterized by hot and dry summers and mild winters, during which most of the precipitation is observed. High pressure is the dominating factor in the summer, when precipitation is very small and if there is some, it is usually in the form of very short, but intense thunderstorms. In the winter it can sometimes snow, especially at higher altitudes, but in general the winters are mild.

This climate type is most common in western coasts of continents in the middle latitudes, for example it includes areas on the West coast of the U.S. such as California, Southern Europe or Southwest tip of Australia.

  • hot summer: warmest month with average temperature between 23 and 28 °C
  • cool winter: coldest month with average temperature between 0 and 10 °C
