Best time to visit Dubrovnik: month-by-month weather (2026)

The strongest months for visiting Dubrovnik, based on visit scores, are June, July, August, and September. These months combine the warmest weather, with highs of 27.5C in June rising to 30.8C in July and August, alongside the most sunshine, peaking at 13.8 hours a day in July and 13.4 hours in June. Rainfall during this stretch is also at its lowest, only 52mm in both June and July, making these months the most reliable for outdoor sightseeing and swimming.

The trade-off is that peak season brings both heat and crowds together, and daytime highs near 30.8C in July and August can feel intense without shade or a sea breeze. Outside this window, weather turns wetter and cooler: November sees the heaviest rain at 293mm alongside a drop in sunshine to 6.6 hours a day, while January and March offer milder alternatives for travelers who prefer quieter streets over guaranteed sunshine.
