Bulgaria Temperature

Bulgaria Temperature

Temperature in Bulgaria varies a lot over the course of a year. The highest ever recorded temperature in Bulgaria was 45.2 °C (in 1916) and the lowest temperature was -38.3°C (in 1947). Why there is such a huge temperature difference? Well, Bulgaria temperature are affected by the specific location in Bulgaria (inland, coastal or mountainous region) and four distinct seasons (spring, summer, winter or autumn).

Average temperature in Bulgaria

The annual average temperature in Bulgaria ranges between 6.3°C and 15.2 °C. Generally, the southern parts of inland Bulgaria have the warmest temperature due to the Mediterranean influence. While northern and eastern mountainous districts of Balkan Mountains tend to be cooler due to higher altitudes. Average high and average low temperatures in Bulgaria recorded over 20 years:

Bulgaria Temperature by season

Due to Bulgaria's location within the continental and Mediterranean climate influences, there are four distinct seasons in Bulgaria, with significant temperature variations. Summers in Bulgaria tend to be the hottest and winters the coldest seasons, while spring and autumn have temperature ranges somewhere in between.

Spring - season of blossom

Spring in Bulgaria starts when trees begin to blossom, which takes place around March. While temperatures gradually rise and snow melts, the landscape starts to transform with lush green colors. Spring temperatures tend to fall between 15°C and 25°C, rising as the summer gets closer. The exception here are Bulgaria's highest mountains that have snow cover well into June.

Summer - season of bathing and hiking

Summer begins at the beginning of June with temperatures typically rising to around 30°C: the hottest season in Bulgaria. Bulgarian summer is the best time to enjoy sea- and sun-bathing , as well as hiking. Although temperatures can sometimes be as high as 40°C, the sea breeze or cooler mountain air will keep you comfortable. The sea water is pleasant to swim in, generally being over 20°C.

Autumn - season of harvest

Autumn begins; days get shorter, temperatures fall, usually noticeably so by around mid-September. You can expect temperatures between 10°C and 25°C, gradually falling as December approaches. The beginning of autumn in Bulgaria tends to be warm enough for beach activities and hiking. It is also grape harvesting season for wine makers.

Winter - season of skiing

Bulgarian winter begins in December, and temperatures typically start to drop below freezing (below 0°C). By the end of the month, you can expect the first snowfall. Temperatures between -5°C  and -15°C in winter months are not uncommon in Bulgaria. Snow cover in Bulgaria's ski resorts usually lasts from December till March, offering excellent skiing conditions.
