Serbia has a moderately continental climate with warm to hot summers and cold winters in the north and relatively mild winters in the south, close to the Adriatic; The climate falls under various Köppen classifications: Cfa, Cfb, Dfa, Dfb and Dfc based on region and altitude. Serbia shares borders with Montenegro in the southwest, Bosnia, and Herzegovina in the west, Croatia in the northwest, Hungary in the north, Romania in the northeast, Bulgaria in the southeast, and North Macedonia along with Albania in the south. The temperate latitudes, presence of high mountain ranges, and the distance from major water bodies influence the climate of Serbia largely.
Serbia is a landlocked sovereign state that sits on the southern parts of the Pannonian plain at the junction of Central and Southeast Europe. The topographical features mainly include forests, farmlands, hills, mountains, rivers, and river valleys. The Dinaric Alps, Carpathian, Rhodopes, and Balkan Mountains are parts of mountain ranges that cover a large part of Serbia. The northern Vojvodina region consists of rich and fertile plains aided by the Danube river. The Morava river flows through the south, which consists of hills, mountains, limestone ranges, and river basins. The central and western parts have hilly terrain interspersed with rivers and creeks, while the eastern part consists chiefly of limestone ranges.
Serbia has four distinct seasons with the average annual temperature in the 6.1°C (43°F) to 11.1°C (52°F) range depending on the altitude. Summers are warm to hot with the average high temperatures between 26.7°C (80.1°F) and 32.2°C (90°F) during the peak of August. Hot Saharan air can bring heat waves in the summer. Winters are cold and snowy in the north, while the south has relatively mild temperatures due to the Mediterranean influence. Polar air masses can penetrate the country and further plummet the temperatures below freezing. Spring is damp and cold and receives snow in some parts of Serbia. Autumn is cloudy and wet, particularly during November in the western part of the country.
The annual precipitation varies by region with 584.2mm (23") in Vojvodina in the north and east, and 609.6mm (24") in the south. Central Serbia with Belgrade accounts for 685.8mm (27") of rainfall, while the western part receives slightly more than 685.8mm (27"). Kosovo's westernmost part is significantly rainier at 812.8mm (32"). The mountains receive more than 1016mm (40") of rain at altitudes above 1000 meters. May and June are generally the rainiest months in Serbia. The snow cover lasts from November to March, with the majority of the snowfall in January. Snowfall is moderate in the southern region while it increases with altitude and lasts for approximately 120 days on the higher mountain slopes. The annual sunshine varies from 1500 to 2200 hours, according to the region. Serbia experiences thunderstorms and is prone to flooding during late spring and early summer. Fog is prevalent in many places on winter mornings.
Smederevska Palanka recorded the highest ever temperature of 45.6°C (114.1°F) on July 24, 2007, in Serbia, while Karajukića Bunari recorded the coldest temperature of -39.5°C (-39.1°F) on January 13, 1985.
The best time to visit Serbia

The worst time to visit Serbia
The worst time to visit Serbia is the cold winter season from December to February, and it is prudent to avoid the borderline months of November and March. Serbian winters can be severely cold, especially in the north and above altitudes of 1000 meters. The temperatures can quickly drop below freezing and occasionally even below. Siberian winds routinely reach the plains of Serbia, and ice storms are common in the winter. Snow, heavy frost and fog takes a toll on the everyday life of the population. The daylight hours are short in the cold months, and the scarce sunshine keeps the skies bleak for extended periods.
Serbia is vulnerable to intense thunderstorms during late spring and early summer, while the winter is prone to ice storms. The warm temperatures melt the snow on the upper mountain ranges by April and along with heavy rains cause flood conditions. Lightning and thunderstorms are frequent during the warm months, and excessive rainfall in a short period can swell rivers, small streams, and creeks. Ice storms are common in the winter and accumulate moderate snow deposits, but more importantly, affect everyday life.
Weather in January
January is the coldest month of the year in Serbia as the winter brings snow, heavy frost, and dense fog in many parts of the country. The temperatures plummet below -17.8°C (-0°F) in the plains and -23.3°C (-9.9°F) at altitudes above 1000 meters in the face of polar winds that blow from Siberia. The average high temperatures are in the 2.2°C (36°F) to 3.9°C (39°F) range, while the average low temperatures are in the cold -7.8°C (18°F) to -5°C (23°F) zone across the country. January is the snowiest month of the year, with an average accumulation of 254mm (10"). The sunshine limits to 2 to 3 hours in the majority of the Serbian lands as the skies remain mostly bleak. Belgrade, the capital, is relatively mild with average temperatures between -2.2°C (28°F) to 3.9°C (39°F). New Year is the time to put on the warm coats, gloves, caps, and shoes in Serbia. Winter sports enthusiasts find the snow accumulation suitable for their purpose.
Weather in February
February is a cold winter month in Serbia that sees icy precipitation, moderate snowfall, and scarce sunshine. Novi Sad in the northern Vojvodina region has average temperatures in the -2.2°C (28°F) to 6.1°C (43°F) range, while the average temperatures across the country remain in the cold to mild zone of -3.3°C (26.1°F) to 10°C (50°F) zone. Snowfall is moderate on the mountain slopes of the Dinaric Alps, which barricade the southern part of Serbia from the cold air masses. The average humidity varies from 65% to 75% across the country, as February tends to be the driest month of the year with 25.4mm (1") to 38.1mm (1.5") of rainfall. Serbian winters harbor indoor music festivals, which see a fair amount of international tourists along with domestic ones. For those who wish to visit the mountains, the cold is a formidable barrier, and the terrain is hardly conducive in February. The sunshine of hardly 3 to 4 hours means that winter coats are a necessity to withstand the cold.
