Novi Sad in May

July means EXIT Festival, which transforms the city but also triples accommodation prices. If you're not here for the music, skip this month unless you book way ahead and don't mind crowds. May through September gives you the best weather and outdoor life. The Danube beaches open up, street festivals happen regularly, and you can actually enjoy walking around. August gets hot - we're talking 35°C+ some days - but the river keeps things bearable. Shoulder seasons work well too. September still has warm days but fewer tourists. May can be rainy, but when it's nice, the city feels perfect. Winter gets cold and gray, though the Christmas market in Trg Slobode has its charm if you don't mind bundling up.
