The weather Dubrovnik during the Spring and Summer is mainly sunny. If you want to swim in the Adriatic crystalline waters you should go in the Summer, so from June/July. But if you don’t need to enjoy bathing and you want to discover the history of the city and the local culture, then you can go in the Spring too and you’ll probably find less tourists. Dubrovnik is in Croatia, which we can’t forget that is in the Balkans, which means that Winters and Autumns are quiet cold, rainy and even snowy, so if you don’t like the cold weather don’t go from October Until May.
Even though Croatia is already in the European Union, the official currency is still the kuna (HRK). So you can have an idea, 1 euro is 7,44 kunas. In some touristic places they also accept Euros, but maybe they won’t have the exact change, soit is recommended to always have kunas with you. In general, if you are from a country in the European Union, you can pay by card without any tax charges.
Shops in the region are usually open from 9h until 19h or 20h. Most of them don’t close for the lunch and they can close even later during the holidays periods. Some commercial centres have wider opening hours. Restaurants don’t close at any time, they are open from the morning until the midnight.
