Bulgarian climate

The climate in Northern Bulgaria is moderate continental, while the climate in Southern Bulgaria is intermediate continental tending to Mediterranean. The climate in the regions with an altitude of 1900-2000 m above sea level is mountainous and along the Black sea coast it is maritime. The climate of the seaside regions is milder in the winter and cooler in the summer than the climate of the interior of the country. The average annual temperature is 10,50 °C, in winter about 0°C (the lowest temperature – 38,3°C – was measured in 1947). Average summer temperatures rarely exceed 30°C.

Marked by four distinct seasons, Bulgaria enjoys a generally favorable climate that is one of the country’s best features. Although located at the same latitude as southern New England, Bulgaria’s climate is noticeably more temperate. Summers are typically hot and dry, but rarely oppressive, with moderate relative humidity. Winters are cold but not bitterly so. In the south and Black Sea coastal regions, Mediterranean influences temper the harsher continental climate of the interior. The country’s half-dozen mountain groups also play a significant part in determining regional variances.

Bulgaria is situated in the moderate climatic zone. The country can be conditionally divided into two climatic zones. The Stara Planina Mountain is considered the watershed between them. Winters are colder in Northern Bulgaria and much milder in the Southern part of the country. Winter temperatures vary between 0° and 7°C below zero. Very rarely temperatures may drop below 20°C below zero. Typical continental and changeable is the climate in spring. It is exceptionally favourable for the growth of fruit-bearing trees, for whose fruit Bulgaria has been renowned in Europe for centuries. Summer is hot and sweltering in Northern Bulgaria, especially along the Danube River.

The Rodopi Mountain

The climate in Southern Bulgaria is determined by the air-currents from the Mediterranean. Summer temperatures do not reach the extremes as in Dobroudzha and along the Danube and are usually moderate: about 28°-30°C. The highest readings are usually taken in the towns of Rousse and Silistra, sometimes reaching above 35°C. Autumns are mild and pleasant in Bulgaria. The multi-coloured for-ests in autumn add to the picturesque landscape. Autumn showers in principle are more frequent than in spring. May, October and November are the rainiest months.
