Weather for Slovenia
Generalised Weather Summary for Slovenia

Summer: June / July / August

Temperatures soar into the thirties (30C, 87F) in July and August and most of the country bakes in golden splendour except for the alpine north west (Kranjska Gora, Bled) where temperatures are generally cooler by the odd 5 or 10 degrees centigrade (perfect for hiking and walking). The warmish weather can throw up days with short and sharp storm activity with spectacular displays of lightning for all.

Despite the queues at major attractions, summer is a great time to visit. Many people like to sightsee in the cool of the morning, enjoy a long lunch in the shade of a local gostilna or perhaps take a swim in the plethora of watering holes around the country. In the evening, what better way to take in the local culture than a leisurely stroll with an ice cream before heading off for dinner and maybe a spot of late evening drinking at a local drinking hole.

Autumn: September / October / November

Autumn is also a brilliant time to visit. The crowds thin out as workers go back to the office and school recommences. From September, the temperature drops down into the comfortable early to mid 20's and the waters are still warm enough for a relaxing dip. Magnificent autumn colours abound and the weather is still good for hiking, walking and anything else you care to do. The guest houses and campsites wind down, and restaurants and cafes start the gloomy task of packing up their outdoor furniture. With the cooler weather, expect a little more rain going into October and especially November as the locals begin storing firewood for the oncoming winter.

Winter: December / January / February

If you're not coming to Slovenia to indulge in the many winter activities like skiing or skating, then the bleakness of winter might appear gloomy to most. The weather is bitterly cold in most of the country and only a tad warmer on the coast. The winds can be fierce and snow can fall at any time. Having said that, Slovenia can still be a magical place. The ski resorts do a roaring trade in apres-ski cocktails and on clear, crisp days, Ljubljana's streets glisten with curtains of crystallised icicles on a background of white calm.

Spring: March / April / May

Slovenia awakens again from its hibernation. The melting snow turns rivers and waterfalls into gushing currents that wash down through the valleys coming into full bloom. The weather is unpredictable but its a great time to be spontaneous. Get out there and feel the changing of the season.

Once in full swing, Slovenia basks in the excitement of warmer times ahead. Some days remain cold, some clear and sunny, some days wet and miserable, some days windy, some days still. By May, the polo shirts and Raybans are back in vogue. Let the good times roll.

Rainfall
Rainfall is heaviest during October/November and continuing on and off until May. It is most prevalent in the alpine areas where the weather can change in a matter of 30 minutes. This is why it is often hard to predict the weather around Bled and surrounding areas.
The annual amount of rainfall decreases as you move from the coast towards the northeast of the country and most rain is brought forth by southwesterly winds.

Snowfall
Snowfall normally occurs during the months from December to February but snow can linger on the mountains till May. Snowfall varies from year to year and from place to place and some years are quite green with very little snow. The deepest snowfall ever recorded in Ljubljana was in 1952 measuring 146cm thick.
See the 'Winter Sports' page for more related information on snow falls.

Earthquakes
All of Slovenia is susceptible to earthquakes with the Upper Soca in the North-West of the country being the most prone to seismic activity. Ljubljana and the centre of the country falls into the next category while the the North-East is considered to be the least prone to seismic activity.

In 1348 about 500 people were killed in an earthquake near Villach. In 1511 there was another major quake near Ljubljana while in 1895 Ljubljana experienced its worst tremor with major damage in the capital.

In 1976 a strong earthquake struck along the border with Italy. Another quake measuring 5.6 struck the Bovec region in 1998 with heavy damage reported. This was followed by a 5.1 quake in the same region in 2004.

The 'Burja'
The Burja is a wind that affects a large portion of the western part of the former Yugoslavia and down the eastern coast of the Adriatic. It is most prevalent in winter and blows hard from the northeast when a high pressure area sits over the mountains and a low pressure area lies south in the warmer Adriatic. As the air gets colder at night, the Burja increases.

The wind can blow at speeds up to 200 kilometres plus per hour and is an integral part of Slovenia's Vipava Valley and the Karst region which lie in the west of the country.

You will notice stones on house rooftops in these areas to stop roof tiles flying off in the strong winds.
In winter, the Burja plays havoc with local roads as snowdrifts frequently occur, blocking off roads and sometimes entire villages (a perfect excuse for kids not to go to school!). Trucks have overturned as unsuspecting drivers underestimate the force of the Burja.

The wind rolls off the hills in the Vipava Valley and rolls down the Karst region towards Trieste which can often be hit hard by the Burja.
