The best time to visit Sofia

In short

The best time to visit Sofia is late spring (May to June) and early autumn (September), when the weather is mild, the parks are green or turning gold, and the city is pleasant to explore on foot. Summer is warm and lively, while winter is cold and quiet — though it doubles as ski season for nearby Vitosha. For the sweetest balance of good weather and manageable crowds, aim for the shoulder months.

A great time for sightseeing and walking the city with comfortable temperatures and blossoming parks.

Autumn (Sep–Nov)

Weather: Mild and often sunny in September, cooling and wetter through November.
