Herceg Novi in June

May through September gives you the best weather and open restaurants, though July and August bring crowds and €200+ hotel rates. June and September hit the sweet spot – warm enough for swimming, fewer tourists, and shoulder season prices. The Mimosa Festival in February fills the town with yellow blooms, but half the restaurants close for winter. Spring comes early here, with March temperatures already hitting 15°C. Summer temperatures hover around 28°C, perfect for those concrete swimming platforms. But here's the thing – even peak season feels relaxed compared to Dubrovnik or Split.
