• 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.
