Weather
River in the forest
Serbia's seasons are very distinct. Winters (December-February) can be relatively cold as the western mountains can receive a significant amount of snow. Lower land, such as Belgrade, is much warmer and during this time averages about 40˚ F (4˚ C).
The spring and fall (autumn) are clearly warmer than winters, but the mountains can still be impassable due to snow.
Summer temperature averages are 72-82˚ F (22-28˚ C) in Belgrade, but again, cooler at elevation in the mountains.
Wildlife
There are a number of large mammals that live in Serbia, including the bear, deer, and the boar. Additionally, there are dozens of small mammals like the rabbit and fox. Fish and other sea life are not too common since Serbia is a landlocked country, but they have a number of species in their lakes and rivers.
There is a large number of birds in Serbia, including pheasants, cranes, ducks, and geese.
