Cfbk Subtropical climate with evenly distributed precipitation with warm summer with cool winter
Traditional Koppen classification: Cfb (Oceanic 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
  • b - temperature of each of the four warmest months is higher than 10°C, but the temperature of the warmest month is less than 22 °C

The Cfb climate type is an oceanic type of climate with mild winter and evenly distributed precipitation. Average temperature of all months is less than 22 °C, which is what differentiates it from the Cfa type. Meanwhile at least four months have average temperature of 10 °C or more.

Just like precipitation, also temperatures tend to be relatively constant and differences between day and night are not very big. Precipitation throughout the year are frequent, but not very intense and sometimes even many wetdays in a row can occur. In the winter and in the autumn are common fogs and during the year also thunderstorms.

Winters are mild (temperatures only very rarely drops below 0 °C and if, then only very slightly) and summers nicely warm. Frontal activity causes lot of cloudiness and relatively high humidity in the autumn, winter and spring.

The total annual rainfall ranges usually between 500 and 2500 mm and in the winter it sometimes also snows.

Temperate oceanic climate Cfb can be found for example in the United Kingdom, Western part of France, Germany, on the West coast of Europe, Northern part of Spain, some parts of South America (Southern and Northern tips), in Southeast Australia and New Zealand.


Modern Trewartha classification: Cfbk (Subtropical climate with evenly distributed precipitation with warm 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.

  • warm summer: warmest month with average temperature between 18 and 23 °C
  • cool winter: coldest month with average temperature between 0 and 10 °C
