How the months are picked.A month qualifies when its average high sits in the comfortable 20–28 °C band (scored down towards 9 °C and 37 °C), rain days are few and sunshine hours are high — at least 78 % of the city's best-scoring month. July and August are then set aside as peak season (school-holiday crowds and prices) whenever at least three other months qualify; where summer is the only comfortable window they stay. Figures are ten-year averages (2016-01-01 to 2025-12-31) from ERA5 reanalysis data via Open-Meteo (CC BY 4.0) for the city centre coordinates.

When to go, and what to expect
Spring (Mar–May)
Ideal for walking Kalemegdan and riverside cafés — one of the best windows of the year.
Summer (Jun–Aug)
Great for river beaches and nightlife, but the heat and crowds put July–August behind the shoulder months.
Autumn (Sep–Nov)
September and October are superb — warm, dry and calm; skip late November.
Winter (Dec–Feb)
For those who like low prices, cosy cafés and a festive city — not for outdoor sightseeing.
