Traditional Koppen classification: BSh (Hot semi-arid climate)

Official definition:
  • B – 70 % or more of the total annual rainfall is during the summer half of the year and r (r = average total annual precipitation in mm) is less than 20t + 280 (t = average annual temperature in °C), or 70 % or more of total annual precipitation is during the winter half of the year and r is less than 20t, or no half of the year has less than 70 % of total annual rainfall and r less than 20t + 140. Summer half of the year in the Northern hemisphere is from April to September, on the Southern hemisphere from October to March.
  • S – r is less than half of the upper limit of B type classification parameter
  • h - t is equal to or greater than 18 °C

The hot semi-arid climate is found in tropical and subtropical regions. Summers tend to be hot, sometimes extremely hot and winters mild. This climate type is commonly found for example in western Africa, India, parts of Mexico and some regions in Southern USA. It is usually found deep inland as a continuation of the tropical desert climate.

It is also characterized by large temperature range and relatively low precipitation.


Modern Trewartha classification: Csal (Subtropical climate with dry summer with hot summer with mild 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
  • mild winter: coldest month with average temperature between 10 and 18 °C
