Country Summary

This page presents high-level information for Slovenia's climate zones and its seasonal cycle for mean temperature and precipitation for the latest climatology, 1991-2020. Climate zone classifications are derived from the Köppen-Geiger climate classification system, which divides climates into five main climate groups divided based on seasonal precipitation and temperature patterns. The five main groups are A (tropical), B (dry), C (temperate), D (continental), and E (polar). All climates except for those in the E group are assigned a seasonal precipitation sub-group (second letter).  Climate classifications are identified by hovering your mouse over the legend. A narrative overview of Slovenia's country context and climate is provided following the visualizations.

Slovenia is located in Central Europe with geographic coordinates of approximately 46°N latitude and 15°E longitude. The surface area of the territory is 20,273 km2 and its coastline length is about 46 km. Slovenia shares boarders with Austria in the north, Hungary in the east, Croatia in the south and Italy in the west. The majority of its surface (58.4%) is covered by forests. In 2016, the population of Slovenia reached 2,065,042, of which 54% live in urban areas. In 2014-2016, annual GDP growth averaged around 2.3%. Slovenia’s climate is extremely diverse. Near the coast, the prevailing type of climate is sub-Mediterranean, in mountains Alpine, while a continental climate prevails in the flat parts of eastern Slovenia. These climate types interact and together with local influences form a wide range of local climatic conditions. The average temperature in the recent 30-year period increased by approximately 1.5 °C. Annual precipitation varies to a great extent, from 800 mm in the extreme north-eastern and 1000 mm in the extreme south-western part of the country, to over 3000 mm in the north-western part of the country. Slovenia submitted its Nationally Determined Contribution (NDC) as an EU Member State in 2015 and its Seventh National Communication in 2018.
