Climate of Slovenia

Where is the country of Slovenia located? Slovenia is a country located northeast of the Adriatic Sea, bordering Italy, Austria, Hungary, and Croatia. The country has a relatively short coastline, which makes it less popular among Dutch tourists than neighboring Croatia as a destination for a sun holiday. Slovenia’s predominantly temperate climate is also responsible for the country’s lower interest as a sun destination compared to Croatia, where summers are drier and less changeable on average than in Slovenia. Slovenia has several climatic zones. In the southwest, the coastal areas have a Mediterranean climate, which further inland changes into a moderate maritime climate (type Cfb according to the Köppen climate system). The higher areas in the north and northwest have a moderate continental climate (type Dfb), which changes into a cool continental climate (type Dfc) on the highest mountain peaks.

Four Seasons

Slovenia, like the Netherlands, has four seasons. The winter is relatively mild in the low-lying areas and along the coast, in the areas above five hundred meters the winters are cooler and there is a higher chance of periods with moderate or even severe frost. March, April and May is spring, with temperatures and weather conditions being very fickle. Dry periods with temperatures well above the long-term average can alternate with sometimes changeable and/or too cool weather for weeks. The summer months are quite warm, especially in the southwest and east temperatures can regularly reach the limit of thirty degrees. In the mountain areas the temperature is generally a bit lower than in the areas that are a maximum of a few hundred meters above sea level. September can give a nice late summer locally,


Due to its location south of the Alps, Slovenia is a relatively wet country. In fact, northwestern Slovenia is one of the wettest regions in Europe, with an average of 2,500 to 3,000 millimeters of precipitation per year, most of which falls in the form of snow in winter. This means you can enjoy winter sports in Slovenia. Measured over the whole of Slovenia, there is an average annual rainfall of about 1300 to 1400 millimeters. The east is the driest region, still with a significant amount of about 800-900 millimeters per year.
