Cfa

Humid subtropical climate

Cfak

Subtropical climate with evenly distributed precipitation with hot summer with cool winter

Traditional Koppen classification: Cfa (Humid subtropical 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
f – precipitation is relatively evenly distributed throughout the year and do not fulfill classification criteria for s or w type
a - temperature of warmest month above 22 °C

The Cfa climate type is typical for areas on the Eastern coasts of continents, mostly between 20th and 30th latitude. The average temperature of the warmest month is higher than 22 °C and the temperature throughout the year range from usually -3 to 18 °C. In the winter, however, in some cases it can be well below freezing point.

Precipitation is relatively evenly distributed during the entire year. Humidity tends to be higher during the summer half year, when the conditions resemble the humid tropical climate. The total annual rainfall can be quite variable, most commonly between 650 and 2500 mm. Thunderstorms during the summer are frequent.

Cfa climate type can be found for example in the Southeastern USA, Northern part of Argentina, Uruguay and Southern part of Brazil, Southern Japan and South of China.

Modern Trewartha classification: Cfak (Subtropical climate with evenly distributed precipitation 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 Cf subtype is characterized by precipitation evenly distributed throughout the year.

It can be found for example in Eastern part of South America, in large areas in Southeast U.S., Northern Italy, the Southwest tip of Russia, in Southeast Asia, some parts of Japan or East coast 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
