Visiting Slovenia in September: all you need to know
September is one of the best months to visit Slovenia. It’s the start of Autumn, the season that brings fall colors to the mountains and a lovely breeze of fresh air after the summer.
September is considered one of the shoulder months in Slovenia. It is significantly emptier than July and August, so it is a very pleasant time to visit.
We have lived and traveled through Slovenia for over 5 years now, so we have experienced it across all seasons. We have put this guide together to help you plan the right things to do when visiting Slovenia in September.
Weather in Slovenia in September
Slovenia is the month that marks the transition from Summer to Autumn. The start of the month is still very warm, with summer-like weather.
Towards the end, it already feels much more like autumn, with a cool breeze in the air.
This is the average temperature in Slovenia in September:
| Celsius | Fahrenheit | |
|---|---|---|
| Minimum temperature (avg) | 15oC | 59oF |
| Maximum temperature (avg) | 25oC | 77oF |
In terms of rain, September is not typically a month known to rain a lot. There could be a few days of rain, but it is normally quite a sunny month.
This, however, has been changing a bit in the past couple of years with the weather getting quite unstable in Europe in general. If you want to increase your chances of getting good weather during your trip, I’d recommend aiming for the start of September.
Pro tip: If you want to see the fall colors in the Triglav National Park, aim to come at the end of September/start of October

Costs of visiting Slovenia in September
As I mentioned, September is considered a shoulder month.
Prices at the start of the month tend to be higher than at the end. That’s because the end of the month is already when everything starts getting quieter in preparation for the down season.
I personally think this is a great month to travel to Slovenia, also in terms of cost. You will be able to visit all the attractions, and it is possible to find some great deals on accommodation prices.
Pro tip: You might find the best fares when booking a stay during weekdays.
What to pack for visiting Slovenia in September
Slovenia is a month that typically has good weather, but it is not as hot as summer anymore.
So, here are our recommendations for what you should bring:
- Layers of clothes: something light to wear during the day and something a bit warmer for the evenings (especially if you will be going to the mountains)
- Hiking shoes
- Hiking poles
- Rain jacket
