Bulgaria has a temperate continental climate typical of Central Europe, but for its coastline along the Black Sea which has a Mediterranean climate. The weather is moderate and the seasons are distinct, with long, hot summers and relatively mild winters. 

Springtime may be foggy and unpredictable in early March, but temperatures become warmer by June, rising to about 70°F (20°C). That said, the high altitude mountain areas remain snowy well into July, when the summer heat arrives.  

Summer in Bulgaria starts in June and finishes towards the middle of September. Temperatures hover around 77°F (25°C) but can rise to 104°F (40°C) on a sunny and clear day. While the interior of Bulgaria can be extremely hot, the coastal areas offer a refreshing breeze and averages around a comfortable 70°F (20°C). Expats should note that violent summer thunderstorms and dangerous hailstorms can occur on occasion. 

Temperatures don't often drop below 50°F (10°C) during the short autumn from mid-September to October. While rainfall increases, it is dry compared to the rest of Europe. As the season progresses, winter brings more snow than rain. 

Winter lasts from late October through to mid-March and offers great skiing opportunities because of the abundant snowfall. Expats can expect temperatures as low as 23°F (-5°C) or 5°F (-15°C) in the coldest regions. That said, it is often clear and sunny, softening the effect of the biting cold and making the thick snow enjoyable.

There have been several devastating floods in this region of Europe. While these are infrequent, violent storms and heavy snowfall are common and should be considered as part of the climate.
