The climate of Bosnia and Herzegovina is conditioned by the main climatic factors: geographical position, geological background, relief, terrain coverage of plant communities and proximity to the Mediterranean. Apart from the basic factors, there are also extreme factors that significantly influence the overall climate picture of Bosnia and Herzegovina. In the first place there are currents of subtropical belt, high air pressure and subpolar belt, low air pressure, which results in the removal of polar and tropical air masses. Then come air masses of polar origins, currents from the Atlantic, cyclones from the Mediterranean and the Adriatic Sea, and anti-cyclones coming from the continental part of Asia. All these circulation-radiation processes greatly disturb the relief that appears as a modifier. The mentioned factors are the reason that there are two main climatic regions in the territory of Bosnia and Herzegovina: the northern and the southern, which separates the line Bihać-Sarajevo-Foča. In the northern region, the climate has a continental character, with cold winters and warm summers. In the southern region prevails Mediterranean climate type with warm summers and wet winters. The line that separates the southern and northern regions is the area of ​​high mountains, plateaus, basin and gorge, in which the typical mountain climate prevails. In this area, winters are cold, with summers of summer with increased intensity of precipitation that are evenly distributed throughout the year, while temperature fluctuations are altered with the altitude region.
Moderate continental climate, extends to the area of ​​the northernmost Bosnia and the valleys of the middle currents of Una, Sana, Vrbas, Bosnia and Drina from Visegrad. Summer is warm. The average air temperature of the hottest month (July) is everywhere between 20 ° C and 22 ° C, while the winter is mostly moderately cold. The average temperature in the coldest month (January) ranges from -1 ° C to -2 ° C. The average annual tempera- ture is greater than 10 ° C. Fall and spring temperatures are uniform. Summer absolute temperatures can rise to 40 ° C, and winter absolute minimums can fall to -35 ° C. The average annual rainfall varies from 700 mm in the east to 1 500 mm in the west. The winds are scarce and weak, and when they occur, they mostly come from the north and northwest directions.
The mountain climate occupies the central mountainous area of ​​our country. This type of climate is most pronounced around the mountains of Oštrelja, Travnik, Sarajevo and Foča. It is characterized by fresh and short summers, cold and snowy winters. The average January temperatures range from -3.5 ° to -6.8 ° C, and in July from 14.8 ° to 16.9 ° C. Absolute minimum temperatures are from -24 ° to -34 ° C, and absolute maximums are from 30 ° to 36 ° C. Exceptions are basins in which temperature inversions occur. Such places are known as frosts; one of them is located on Mount Igman, where on January 25, 1963, a minimum temperature of -43.5 ° C was measured. Thermal fluctuations range from 20 ° to 21 ° C. Autumn is warmer than spring. Precipitation is evenly distributed and ranges around 1,200 mm. Fog is common and has it in all months. Cloud coverage is greater than 50%.
The Mediterranean climate is present in low and high Herzegovina. Therefore, we distinguish two types of Mediterranean climate. The area of ​​low Herzegovina, which corresponds to the lower flow of the Neretva with the surrounding karst fields below 1,000 meters above sea level: these are Ljubuško, Imotsko-bekija, Mostar and Stolacko. This type of climate in low Herzegovina comes from the fact that its area is under the direct influence of sea air. During the winter, the Adriatic Sea radiates into the surrounding area accumulated heat during the summer, so winter temperatures are considerably elevated. The average January temperature in Mostar is 4.6 ° C, Stoco 4.3 ° C, Ljubuški 4.7 ° C. In the summer, the influence of the Adriatic Sea is negligible, due to limestone rocks, which, when warmed, change the temperature of this area. Summer is very dry and hot. The temperature fluctuations range from 20 ° to 21 ° C. Autumn is warmer than spring. The mean absolute minimum temperatures range from -4.9 ° to -8.7 ° C, while the absolute minimum drops to -17 ° C. In this area, the bora is dominant, with shifts with the southern wind. The smallest month is October, and February is the most prolific. The worst month is October, with 200 mm precipitation on average. Snow is almost gone. The annual rainfall varies from 1,000 to 1,500 mm.
The changed Mediterranean climate occupies the area of ​​high Herzegovina. In this higher Herzegovina and southwestern mountainous region the climate is approaching mountain, but with Mediterranean features. The temperature of the air decreases with the rise of the altitude and the distance from the sea. For every 10 km from the sea, the temperature drops from 0.6 ° to 0.8 ° C. Winters are sharp with absolute minimum temperatures from -14 ° to -25 ° C. The average January temperatures range from -1.8 ° to -6 ° C. In the case of absolute maximum temperatures can rise up to 40 ° C. As in Nis, autumn is warmer than spring, but temperature fluctuations have increased. Annually in this area the winds fall to 1 800 mm of precipitation.
