Ljubljana is undeniably among the most uniquely charming cities you’ll ever visit. This small yet vibrant, laidback yet modern European capital has all the perks of a big city while being exceptionally easy to navigate and is an excellent starting point for exploring wider Slovenia.
Truth be told, like Slovenia itself, Ljubljana is a top destination to visit all-year-round. There are always plenty of exciting things to do and interesting sights to marvel at. It depends on individual preferences, of course, so it’s nice to know what to expect according to the time of year.
Although we highly recommend you visit Ljubljana in every season, we’ve nonetheless created a short overview of the city’s features throughout the year that will help you decide on when is your best time to visit Ljubljana.
Ljubljana is strategically situated in a specious basin on the doorsteps of the Alps and holds a near-perfect central position that acts as a crossroads to other major regions of Slovenia, which means it’s affected by the country’s four prevailing microclimates.
Meteorologically speaking, Ljubljana has an oceanic climate, bordering on a humid subtropical climate zone with continental characteristics, such as warm to hot summers and moderately cold winters.
Because of its aforementioned location, average temperatures in Ljubljana can vary drastically and are therefore quite difficult to predict. That said, compared to popular tourist destinations worldwide, Ljubljana is known for having very agreeable temperatures.
If you’re looking for the very warmest time to visit Ljubljana, then June, July and August are your safest bet. July and August are the warmest months with daily highs somewhere between 25 and 30 °C (77 and 86 °F) with temperatures rarely dropping below 62.4°F (16.9°C) at night. On the other hand, January is the coldest month with temperatures mostly lingering around 0 °C (32 °F).
Precipitation is relatively evenly distributed throughout the four seasons, yet surprisingly, winter and spring can even be somewhat drier than Ljubljana in summer and autumn. Yearly precipitation is about 1,400 mm (55 in), making Ljubljana one of the wettest European capitals. Thunderstorms are common from May to September and can occasionally be quite heavy.
Snow can be expected from December to February (or later), but snowfall has decreased substantially in recent years. Due to the large marshlands in its vicinity and persistent temperature inversion, Ljubljana is known for its fog (average 64 days of fog per year), mostly in autumn and winter.

Coincidently, April is also the least humid month, and strolling around our capital becomes very inviting.
