Sofia's Climate
Sofia, the capital of Bulgaria, sits in a highland basin around 550 metres above sea level, ringed by mountains, giving it a humid continental climate with four distinct seasons. Summers (June–August) are warm and fairly dry, usually 25–30°C with cool evenings thanks to the elevation, while winters (December–February) are cold, often below 0°C with snowfall that can linger for days. Spring and autumn are pleasant transitional seasons, with autumn dry and gently sunny. Fog and winter air pollution occasionally build up under temperature inversions.
