July is the hottest month in Dubrovnik with an average temperature of 25°C (77°F) and the coldest is January at 9°C (48°F) with the most daily sunshine hours at 13 in August. The wettest month is November with an average of 198mm of rain.

In Croatia, the wettest month depends significantly on whether you are visiting the coastal Adriatic region or the inland continental areas. For the majority of the famous coastal cities like Split, Dubrovnik, and Zadar, November is statistically the wettest month of the year. During this time, the Mediterranean climate shifts into its winter pattern, bringing frequent and heavy rainfall, with averages often exceeding 170mm (6.7 inches) in some areas. Conversely, in the capital city of Zagreb and the northern inland plains, June can often be the wettest month due to summer thunderstorms and heavy convective rain. Across the country, the period from late October through January represents the primary "rainy season." If you are planning a trip in 2026 and want to avoid the rain, July and August remain the driest months nationwide. However, for those visiting the coast in late autumn, it is essential to pack high-quality waterproof gear, as the rainfall in November can be intense and persistent, often accompanied by the strong "Bura" or "Jugo" winds.
