When should you visit Ljubljana?
Ljubljana is a compact, walkable capital with a car-free old town along the river. Summer is warm and lively, with open-air concerts and riverside cafés. Autumn is the rainiest season, winter is cold and often foggy, and December brings a big festive program. Late spring is the sweet spot. Here is how all twelve months compare for weather, crowds, prices and events.
