Climate Data Historical

Bulgaria is characterized by two climatic regions: a continental climate in the North and a Mediterranean climate in the south. The Balkan Mountains drive differences between the Northern, continental climate and the southern, Mediterranean climate. Continental climate is generally humid and characterized by cool summers. The continental north tends to have higher variation in temperature and precipitation compared to the coastal regions. The country is showing a tendency toward warming.There has also been observed increase in frequency of extreme weather, particularly number of days with high precipitation and a reduction in snow accumulation.


  • Average annual temperature consistently surpassed the average temperature after mid-century and continues to hit record highs.
  • The observed average annual temperature for 2015 was 1.12 °C above average.
  • Temperatures in areas near continental climate tend to have higher variation while areas of the country with a Mediterranean climate tend to be moderate.


  • Bulgaria has experienced changing precipitation patterns. Bulgaria saw average annual precipitation of 49.7mm in 2013 which was 1.7mm below average then experienced 29.4 mm above average annual rainfall the next year (80.9mm).
  • Precipitation levels tend to be higher in western regions compared to regions that have Mediterranean or continental climates.
  • Areas that traditionally experience continental and Mediterranean climates are experiencing lower levels of precipitation, on average, over the past century.
