Serbia's continental climate means real seasons — hot summers, cold winters and excellent spring and autumn windows. The city (Belgrade and Novi Sad) is good year-round; the monasteries and Zlatibor mountains are best May–October.
✔ Best overall: May–June and September
✔ Best for EXIT Festival: July (Novi Sad)
✔ Best value: March–April and October–November
✔ Avoid: August for city sightseeing (very hot inland)
✔ Best for nightlife: Year-round — Belgrade never sleeps
