Croatia has two fairly distinct weather patterns – the coast experiences warm summers and mild winters while the inland regions see slightly higher summer temperatures and freezing winters.
Summer in Croatia and Slovenia runs from June to August. It’s peak tourist season with glorious weather and warm sea temperatures, and everyone heads to the coastal towns. Day time highs average from 75°F in June to 85°F in August. Further inland, temperatures are in the high 70s.
Fall brings about dramatic change in scenery and provides some of the best weather conditions for sightseeing. September, mainly, is a great month to travel to Croatia and Slovenia. Temperatures drop from the mid-70s in September to 60°F in November and rainfall levels increase.
Winter, while cold in Croatia and Slovenia, is breathtaking with otherworldly landscapes. Temperatures on the coast are between 45-50°F while further inland, the mercury drops to below 40°F.
Spring is a good time for city exploration as the day time highs steadily rise from the low 50s in March to the low 70s in May.

What to Pack
With significant differences in temperatures and weather conditions across seasons, what you pack for your travels in Croatia and Slovenia depends on when you are visiting.
If you are heading to the beaches during summer months, then apart from your swimwear, you’ll need to pack sunscreen, a sunhat and sunglasses. For evenings when you want to explore the town, get a maxi dress or a smart top and skirt. A denim jacket or light shawl is advisable for times when it gets windy.
There is plenty of walking to do in Croatia and Slovenia, so a good pair of walking shoes is a must. We also recommend getting an umbrella and a rain jacket to stay dry.
During autumn, the thermometer can drop low enough in the evenings to warrant a sweater or light jacket. Long t-shirts, pants and clothes that you can layer are recommended for the fall months. If you are traveling to Croatia and Slovenia during winter, then a heavy winter jacket, gloves, scarves, and warm clothes are a must.
