the Dinaric mountains) and climate types (submediterranean, temperate continental, mountain climate). These are often quite interwoven. Protected areas of Slovenia include national parks, regional parks, and nature parks, the largest of which is Triglav National Park. There are 286 Natura 2000 designated protected areas, which include 36% of the country's land area, the largest percentage among European Union states. Additionally, according to Yale University's Environmental Performance Index, Slovenia is considered a "strong performer" in environmental protection efforts. Climate Slovenia is located in temperate latitudes. The climate is also influenced by the variety of relief, and the influence of the Alps and the Adriatic Sea. In the northeast, the continental climate type with greatest difference between winter and summer temperatures prevails. In the coastal region, there is sub-Mediterranean climate. The effect of the sea on the temperature rates is also visible up the Soča Valley, while a severe Alpine climate is present in the high mountain regions. There is a strong interaction between these three climatic systems across most of the country. Precipitation, often coming from the Gulf of Genoa, varies across the country as well, with over in some western regions and dropping down to in Prekmurje. Snow is quite frequent in winter and the record snow cover in Ljubljana was recorded in 1952 at . Compared to Western Europe, Slovenia is not very windy, because it lies in the slipstream of the Alps. The average wind speeds are lower than in the plains of the nearby countries. Due to the rugged terrain, local vertical winds with daily periods are present. Besides these, there are three winds of particular regional importance: the bora, the jugo, and the foehn. The jugo and the bora are characteristic of the Littoral. Whereas the jugo is humid and warm, the bora is usually cold and gusty. The foehn is typical of the Alpine regions in the north of Slovenia. Generally present in Slovenia are the northeast wind, the southeast wind and the north wind. Waters The territory of Slovenia mainly (, i.e. 81%) belongs to the Black Sea basin, and a smaller part (, i.e. 19%) belongs to the Adriatic Sea basin. These two parts are divided into smaller units in regard to their central rivers, the Mura River basin, the Drava River basin, the Sava River basin with Kolpa River basin, and the basin of the Adriatic rivers.
