Climate of Bulgaria

General Climate

Bulgaria has a moderate continental climate, but it is influenced by its location in the eastern Balkan Peninsula. The country is exposed to cold and dry winds from the northwest, while the northeasterly winds keep temperatures low during the winter. These factors make Bulgaria cooler than other areas at the same latitude.

The mountains and plains also influence local weather. The mountain regions experience colder temperatures and more snow in winter, while the lowlands and river valleys are warmer and more suitable for agriculture Turkey Sightseeing.

Mean Annual Temperature

Climatological data from 1884 to 1903 give an idea of average temperatures in some important towns:

Sofia (550 metres above sea level): 9.9°C

Plevna (105 metres): 11.2°C

Bourgas (14 metres): 12.5°C

Philippopolis (Plovdiv, 160 metres): 12.4°C

Gabrovo (375 metres): 10.0°C

If we adjust these figures to sea level, the greatest temperature difference among towns is about 15°C, and the average isotherm passing through Bulgaria is 12°C. Considering that the mean altitude of Bulgaria is 425 metres, the average annual temperature for the entire country is roughly 10°C.

Seasonal Temperatures

The coldest month is January, and the hottest month is July. Average temperatures in these months for key towns are:

Town January (°C) July (°C) Difference (°C)

Sofia 1.9 20.6 18.7

Plevna -1.5 23.2 24.7

Bourgas 1.9 22.8 20.9

Philippopolis 0.4 23.5 23.1

Gabrovo -1.1 20.4 21.5

The difference between winter and summer temperatures shows that Bulgaria has cold winters and warm summers, typical of a continental climate.

Climate Summary

Overall, Bulgaria’s climate varies with altitude and region. Mountains are cold and snowy, while plains are warmer and fertile. The north-eastern and north-western winds influence the weather, making winters colder. This climate is favorable for agriculture, forestry, and human settlement, while also giving Bulgaria distinct seasons for tourism and outdoor activities.
