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.
