Slovenia weather overview

Slovenia lies close to one of the world's most beautiful coastlines, edging the Adriatic Sea, but sadly only has a tiny stretch of it within its borders. The Julian Alps experience heavy summer rain and ferocious snowfalls in winter. On lower ground, summer temperatures are high and conditions very sunny, but sudden, fierce thunderstorms can provide dramatic interruptions.

If travelling in the winter, beware sporadic visits from the nasty Bora wind, which whistles in icy blasts from Eastern Europe.
