Slovenia, this remarkably charming and incredibly diverse destination we love to call home, has a powerful appeal that transcends time of year and even weather. There are always places to see that will blow your mind and things to do that will enrich your body and soul.
Despite this universality, we know that tastes differ, so we’ve decided to compile all the best activities, holiday options, and top events according to seasons and individual months.
To navigate smoothly through this lengthy post, feel free to jump to specific points of interest:
The answer depends on one’s preference, of course, but to give you a clearer overview that will help you plan when is the best time to go to Slovenia, we have broken down the seasons first before moving on to individual months, where the weather, activities and events will be discussed in greater detail.
Why? Because Slovenia is among Europe’s smallest yet loveliest and topographically as well as climatically most diverse countries. Traditionally, the country is divided into 4 main physiographic regions which fall under 3 climatic zones that determine the weather.
The climate(s) of Slovenia by region
Slovenia is a textbook example of a country with a prevailing four-season climate.
The mountainous parts (north and northwest) are home to a strict Alpine climate, characterised by cold winters and warm summers. Weather wise, these areas are generally quite unpredictable throughout the year.
Slovenia’s coastline is dominated by a sub-Mediterranean climate with more steady, warmer weather, which brings mild winters and hot summers, comparable to those of sunny Croatia. However, we shouldn’t underestimate the powerful bora (burja) wind that tends to sweep across the Karst region all-year-round.
Central, north- and south-eastern Slovenia have a typical continental climate with chilly winters, relatively warm yet wet springs and autumns, and hot summers.
The fascinating thing is that you can experience quite dramatic shifts in weather, depending on the region and regardless of the season.
The weather and things to do in Slovenia by season
Every season is a season to be jolly in Slovenia.
Like most European countries, Slovenia gets its biggest influx of tourists in June, July, August and September. It’s when the weather is most favourable, perfect for the widest range of activities and most convenient to plan your itinerary. But truth be told, Slovenia is the place to be in any season: April, May and October come highly recommended if you want to avoid the crowds, and wintertime is fantastic for snow-related pastimes and Christmas festivities.
(March to May)
In terms of weather, the codename for spring in Slovenia is “unpredictability”. Although certain activities like sightseeing, hiking (and even occasionally skiing) are doable in early spring, rainfall, windy spells and cooler days reign over most of the country until mid-April.
Late spring, on the other hand, is much drier and warmer and is a superb time to start exploring Slovenia’s natural and cultural highlights. It’s when everything is in bloom and hitting the hiking trails or venturing on cycling expeditions in the grand outdoors becomes a must. Water sports, such as rafting, kayaking and canyoning, are also very attractive on Slovenia’s lush watercourses this time of year.
Springtime offers excellent conditions for holidays in Slovenia. Uncrowdedness, vacant and more affordable accommodations, combined with warmer weather means the time is ripe to visit Slovenia before the onset of the summery high season.
What to pack?
With an omnipresent chance of chillier and rainy days, always be remember to pack some warmer waterproof clothing and good quality walking shoes. Especially if you plan on visiting the mountainous region.
(June until August)
With warm to scorching weather and blue skies invading every corner of the country, summer is when the high peak tourist season in Slovenia is officially open. Besides the occasional summer storm (particularly in August) and the odd shower here and there, the weather is definitely our ally.
The good news is, even during this busy season and Slovenia’s small size, the masses are still manageable and the natural environment is big enough for you to enjoy your stay without feeling overwhelmed, as is common in other, larger European countries.
End of June and early July also happen to be the perfect time to ascend Slovenia’s highest and iconic mountain – Mount Triglav.
The summer’s rising temperatures allow for T-shirts and shorts, particularly in July and August, but remember to pack a lightweight umbrella and some long-sleeved clothes as well. And remember, the Alpine region has a completely different set of rules. Even in summer, weather conditions in the mountains tend to change in a blink of an eye, so a wind stopper jacket, a few warmer layers and waterproof hiking shoes are obligatory. Plus, don’t forget your sunglasses and sunscreen!
(September to November)
Like spring, autumn is a wonderful alternative to summer’s high season. In early autumn, days are still warm enough for outdoor excursions. As this calmer season progresses, Slovenia’s countryside portrays remarkably beautiful colours. Therefore, the fun list of things to do in Slovenia still stands strong.
Experiencing the diversity and richness of Slovenia is super fun in autumn, with amazing cultural holiday options, while city breaks offer a chance to explore our country’s charming urban areas and their colourful surroundings.
Autumn in Slovenia also presents visitors with numerous opportunities to indulge in our tasty gastronomy and spoil themselves silly with the finer things in life on exclusive luxury holidays.
Although autumn is considered the wettest time of year and November ushering in cold temperatures, for many this season represents the most optimal time for a visit.
What to pack?
With every passing day, especially from October onwards, temperatures in autumn decrease significantly, so you will need to pack much warmer clothes. While September still allows for T-shirts and light sweaters, the wetter and cooler months that follow call for jumpers and waterproof coats.
(December to February)
In winter, Slovenia is gorgeous. The Alpine region is transformed into a winter wonderland straight out of a story book. Ljubljana, Europe’s cutest capital, becomes a Christmas fairy-tale, adorned with the most magical decorations. Every bigger town sets up a Christmas market, and despite the cold, there’s always plenty of things to do in Slovenia during this festive time.
The mountainous areas are very cold during winter, but that’s exactly how we like them. There are scores of winter activities for everyone to enjoy and an incredibly lush selection of ski resorts offer amazing winter holidays.
Even other outdoor activities are possible during winter, like fishing or going on certain guided hiking trips. For the bravest and physically fit, the possibility of climbing Triglav or scaling its mighty North Face still exists during winter. And it’s breath-taking!
The coastal parts of Slovenia are very appealing in wintertime, as they exhibit the same Christmassy spirit, but with much milder temperatures.
The final winter verdict is: Everyone who visits Slovenia during this season will undoubtedly fall in love with the place instantaneously.
What to pack?
Needless to say, the temperatures are cold to freezing in Slovenia in winter, so packing your warmest winter coat is certainly a given. Hats, gloves, scarves and waterproof shoes/boots with good grip are also a very useful addition to your traveller’s wardrobe.
The weather and things to do in Slovenia by month
Slovenia is the flavour of the month. Every month.
Now that you’re acquainted with our country’s seasons and some fun things to do in Slovenia in each of them, it’s time to dig deeper.
We are going to present you with a categorical overview of the weather, a list of activities, and interesting events you might want to attend corresponding to each month of the year.
SLOVENIA IN JANUARY
Weather in Slovenia in January
The average temperature in this cold month drops to around -2°C (29°F) and rarely rises above 1°C (34°F), and you can expect the air to get as chill as -5°C (23°F) or lower. January is commonly the driest month in Slovenia, although rain or/and snowfall isn’t out of the ordinary.
Things to do in Slovenia in January
January in Slovenia can be described in two word: winter activities. As the New Year rolls in, Slovenian ski resorts are in operation mode, level 100! Luckily for everyone visiting this winter wonderland, Slovenian ski resorts are among the best in Europe. Uncrowded, affordable and exceptionally accessible, these Alpine havens offer a fun time for every type of skier.
Main events in Slovenia in January
Skiing isn’t just a national pastime to partake in, January (or early February) is also the month everyone is glued to their TVs or cheering for their favourite wintertime athlete at one of Slovenia’s most important sport events of the year: Women’s World Cup Slalom & Giant Slalom Competition. Appropriately dubbed the “Golden Fox”, the championship, which takes place in Pohorje (a giant ski resort on the outskirts of Maribor), is a long-standing tradition that attracts over 20,000 spectators each year. Maribor, Slovenia’s 2nd largest city, also hosts several concerts and other exciting après ski events. On the other side of the country, the world-famous ski jumping resort of Planica also attracts thousands who come to enjoy World Snow Day.
SLOVENIA IN FEBRUARY
Weather in Slovenia in February
The last full month of winter sees slightly warmer days than January, but average temperatures still refuse to exceed -1°C (31°F), with highs reaching around 3°C (38°F). Snowfall is still relatively common, especially in the mountainous region of the Alps as well as the eastern and south-eastern parts of the country.
Things to do in Slovenia in February
The ski season doesn’t let up in February. In fact, it’s in full swing, with tourists and locals hitting Slovenia’s stunning slopes like mad. Besides classical skiing, cross-country trails near the winter hub of Kranjska Gora are awesome, while Pokljuka, a magical high mountain plateau in the foothills of the Julian Alps, offers a traditional sport called snowshoeing. And don’t forget about our highest mountain Triglav and a chance to do some ice climbing up a frozen waterfall to get your adrenaline pumping.
Main events in Slovenia in February
February is as busy as it is cold. It’s when Pokljuka hosts its annual Biathlon World Championship, and on 8 February, it’s National Day of Culture, when Slovenia celebrates its most renowned poet, France Prešeren, author of the country’s national anthem. On this day, museums, galleries and other cultural institutions are entry-free, so if you’re in Ljubljana or any other bigger town at the time, do make sure to visit at least a couple when on your holiday in Slovenia.
Old pagan rituals are also very much alive in February. Slovenia’s original Halloween-tyle masquerade called Pust is happening throughout the country. The biggest and most colourful carnival town of Ptuj marks Shrovetide, the ancient Slavic carnival Kurentovanje, a rite of spring and fertility. A similar folkloric event is held in the cosy town of Cerkno, where masked locals chase down and executing the Pust, representing winter and the old year.
SLOVENIA IN MARCH
Weather in Slovenia in March
The winter temperatures slowly start to subside as Slovenia tips into March. Average temperatures get up to about 3°C (38°F), but can exceed 8°C (46°F) by the end of the month. The average lows gravitate towards the 1°C (31°F) mark. Inland parts of the country often get a good portion of rain.
Things to do in Slovenia in March
With the melting away of winter (if the pagan masks did their job right) the ski season begins to follow suit and give way to leisurely urban-based activities. That, however, doesn’t mean there aren’t any possibilities left to indulge in snowy fun. As an exemplary Alpine capital, Ljubljana itself is located very close to the Krvavec ski resort, which promises great skiing well into March. The milder weather also gives you a chance to explore Slovenia by joining exciting day trips to various parts of the country and visit Slovenia’s main landmarks, practically void of tourists.
Main events in Slovenia in March
Nope, we’re definitely not done with skiing quite yet. Slovenia’s number-one downhill ski event – the Vitranc Cup – takes place at Kranjska Gora in early March and is a sceptical worth attending. Staying near Kranjska Gora, Planica to be exact, ski jumping fans will love to learn that the Ski Jumping World Cup Finals are also organised in March. And the atmosphere at this event, held there since 1934, is truly unbelievable.
SLOVENIA IN APRIL
Weather in Slovenia in April
The first proper month of spring has arrived! Average temperatures linger at around 7°C (45°F), but this statistic includes the Alpine uplands, so expect considerably higher temperatures that can easily exceed 15°C (53°F) on a sunny day. A slightly wetter month than March, April can still get chilly in the evening, so make sure you pack some warmer layers when visiting Slovenia.
Things to do in Slovenia in April
Although the weather isn’t very predictable, April in Slovenia still promises its fair share of activities. Destinations like our charming capital Ljubljana and its surrounding area offer plenty of things to do. If it starts to drizzle, you can always pop into a museum or try some authentic local cuisine on a food tour. The same goes for other popular destinations, like Bled or the much warmer coastal towns of Piran and Koper, or you can go on a bike ride through the vineyards. When climbing up mountains isn’t yet advisable, you can always go underground and join a caving tour of one of Slovenia’s hidden subterranean gems or visit their famous counterparts Postojna Cave or the UNESCO protected Škocjan Caves.
Main events in Slovenia in April
When visiting Slovenia in April, keep in mind that many people take the opportunity to travel around the time of Easter holidays, so expect things to be booked or closed during that time. Slovenia’s oldest town of Ptuj hosts an annual medieval market called St. George's Fair. Just outside Ljubljana, the Volčji Potok arboretum invites you to visit its Horticultural and Handicraft Fair, Slovenia's largest flower and gardening show. To satisfy your sweet tooth, we recommend you pop round to the medieval town of Radovljica, which organises its delicious Chocolate Festival, with cooking demonstrations, workshops and tastings.
