Daylight hours have significantly decreased with 4 to 5 hours of sunshine across the country and the crisp autumn air brings in the morning fog. October is the wettest month, the western plains and interior around Ljubljana see 5 to 6 inches of (torrential) rain along with cooler daily averages of 59- and 52-degrees Fahrenheit, respectively. Up in the alpine northwest, temperatures hover around 45 degrees.
Crowds & Costs
The summer crush is long over and the throng of tourists have departed, you can enjoy Slovenia in relative peace. Airlines and hotels will have introduced shoulder-season rates that offer significant savings, making October an ideal time to visit if you’re in want of avoiding crowds and looking for a bargain.
Where to Go
Most travelers will either start their trip with a few days in Ljubljana before setting out to explore the rest of the country or use Ljubljana as a hub, taking day trips in and around the area. Either way, a popular option to see as much of this small gem of a country on your own schedule is to rent a car.
As October is one of the prettiest times to visit Slovenia, with its fall colors in full swing, popular points of interest would be to explore Lake Bled, Lake Bohinj, and the Vintgar Gorge, before heading further into Triglav National Park and to the stunning Soča Valley.
A common next stop would be to explore the bucolic Goriška Brda wine country before considering a stop in the Karst region to explore the impressive Škocjan or Postojna Caves. From there, work your way down through the Karst region and to the small coastline, getting lost among the picturesque narrow streets and squares of medieval towns like Koper or Izola.

Located along the Italian border, Goriška Brda and its nearly 700 wineries are known as the "Tuscany of Slovenia” and offer plenty of wine tasting options. Try a glass or two of the white varietals from the Vipava Valley.
Visit Slovenia’s many castles without the hassle of long lines, like the medieval Bled Castle perched on a cliff above Lake Bled’s north shore, or the Predjama Castle another medieval example built right into the mouth of a clifftop cave nearby Postojna.

October is still a great time to get in some hiking in places like Triglav National Park in the Julian Alps, trails are well marked and suitable for all levels. Another great option is to hike and explore the beautiful Tolmin Gorges and the Kozjak Waterfall just outside of Bovec in the Soča Valley.
