Weather
It may come as no surprise that July is the hottest month of the year and sees the most daylight (9-10 hours). Average temperatures in the western plains and Portorož range between 66-79 degrees Fahrenheit while further inland around Ljubljana sees temperatures reach as high as 81 degrees and daily lows of 59.
While there is significantly less rain than most other months, up to 4.5 inches of rainfall is to be expected over 9 days. The mountains in the northwest see temperatures range between 50-73 degrees and trekkers should be aware of freak storms that can occur in higher elevations.
Crowds & Costs
July is one of the busiest times of the year, though it's still relatively less crowded than other popular Mediterranean locales. Slovenia’s coastal cities, the capital, and Bled and Lake Bohinj areas see the height of the country’s tourism, hotels filling up fast and restaurants book up months ahead of time, so be sure to plan well ahead. You can also expect a surge in airline and hotel prices.
Where to Go
Travelers this month will enjoy the warm, sometimes hot, and sunshiney weather (with short bursts of thunder and lightning storms). Every region of Slovenia will have something to offer, from the Alpine northwest to the coastal towns along the Adriatic Sea in the south and to ancient Ptuj in the east, not forgetting the lively capital.
The coastal towns, Piran, Izola, and Koper are popular summer destinations, offering a plethora of sea-related activities. Kranjska Gora in the high mountains has great hiking and if you’re brave, alpine lakes, like Lake Jasna to dive into.
The less frequented eastern countryside is a great alternative to explore when the rest of the country is overflowing with visitors. After a few days in Llubljana, turn your attention to Celje, Žiče, Ptuj, Maribor, and Podsreda, for your choice of museums, castles and fortresses, and striking countryside.

What to Do
Take advantage of the great weather and head to any number of swimming holes across the country. Head to the coast and to Piran, Izola, or Koper to cool off in the inviting Adriatic, sun on the beach, or sail along the coastline. Or, swim in the refreshing Alpine rivers like River Nadiža or the turquoise River Soča.
Swim, kayak, or even rent a SUP board at Lake Velenje, and a visit to Slovenia isn’t complete without checking out two of the country’s most popular lakes, Bled and Bohinj. Lake Bohinj makes for a better alternative to the more crowded Lake Bled an hour away.
For a little cultural exploration, visit Ljubljana’s pedestrian-only Old Town, wandering Tržnica Na Prostem (Central Market) and lunch on calamari below the market’s Plečnik Colonnade. Switching gears, lace up your hiking boots and head to Slovenia’s tallest peak, Mt. Triglav in the National Park of the same name, or trek Kranjska Gora, stopping to cool off by Lake Jasna.
Velika Planina offers pretty and unique sights of a shepherding settlement as well as hiking options. The Soča Valley too offers great hiking, as well as is a hotbed for your choice of adventure sports, kayaking, canoeing, river rafting, and even ziplining.
