What’s the weather like in Slovenia right now?
The live forecast above gives you a real-time view for Slovenia, covering the main cities and regions. Conditions can shift quickly in the Julian Alps and along the Adriatic coast, so it’s worth checking the weather in Slovenia over the next 10 days if you’re planning outdoor activities.

How does the weather differ between Ljubljana, Bled and Piran?
Ljubljana typically has a continental climate with warm summers and cold winters, while Bled, nestled among the Alps, can be a few degrees cooler and wetter. Piran, on the coast, enjoys milder winters and sunnier summers thanks to the Adriatic influence. For longer-term planning, the 10-day forecast is more reliable than looking at a 30-day outlook, though general trends for Slovenia can give you a sense of what to expect.
What’s the weather in Slovenia like in September?
September brings mild days (20–25°C in Ljubljana) and cooler evenings, with less rain than October. It’s a popular month for hiking around Bled and Lake Bohinj, though the coast at Piran stays warm enough for swimming.
Can I get a reliable 14-day forecast for Slovenia?
Forecasts beyond 10 days become less certain, especially in mountainous terrain. For a practical outlook, stick with the 10-day view for Ljubljana or Bled. The 30-day trend is useful only for spotting broad shifts, not daily planning.
Is the weather in Slovenia very different from the UK?
Yes – Slovenia generally has warmer summers and colder winters than most of the UK, with more sunshine on the coast. Inland, the mountains can bring sudden thunderstorms even when the coast is clear, so always check localised forecasts.
