DCao Temperate continental climate with hot summer with cold 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: DCao (Temperate continental climate with hot summer with cold winter)

In the Trewartha classification, the category D is like in the Koppen classification, assigned to regions in the temperate zone. The criterion for this type of climate is four to seven months with average temperature of more than 10 °C. In general it is further subdivided into two subtypes: oceanic and continental. These differ in their average temperature of the coldest month.

Temperate climate is characterized by four distinct seasons and there are substantial differences between the temperatures in the summer and in the winter, but the absolute values are not so extreme and the change is gradual.

The continental subtype is typical for regions located more inland and this also means the temperature variation is larger than that in case of the oceanic subtype. The coldest month has an average temperature of less than 0 °C. Summers are usually warmer, while winters colder with snow being quite common.

Continental D climate type can be found for example in parts of Northeast U.S., Central and Eastern Europe and usually these areas are quite densely inhabited.

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