Bulgaria enjoys a temperate climate with hot, dry summers and cold, wet winters, often with heavy snow.
Spring (particularly April to mid-June) is an excellent time to visit. The weather is good, the theatres and other cultural venues are in full swing and low-season rates still generally apply. Summer (mid-June to early September) is ideal for hiking and festivals, but it’s also the peak holiday season, especially on the Black Sea coast. Temperatures can be very high during this period too. September is perhaps one of the best months to see Bulgaria. The autumn trees are glorious, fruit and vegetables are plentiful, the tourist hordes have returned home, and you can still sunbathe and swim in the Black Sea.By mid-October, almost all Black Sea resorts have closed down. As the weather gets colder over the next two months, a gloom about the impending winter (December to March) permeates Bulgaria. Then, as soon as the first snows fall in around mid-December, Bulgarians start to perk up and flock to the ski resorts, which sometimes stay operating until mid-April.
