Weather in Croatia in December

The southern Dalmatian coast and its islands hold the mildest winter conditions in the country, though even here the sea is cold and most seasonal businesses are quiet.

• Dubrovnik: Dubrovnik sits on the far south of the Dalmatian coast and usually has the mildest December temperatures on the mainland. The old town is compact and largely walkable, and its walls can be walked in a circuit of roughly 2 km when the weather allows. Expect short, cool days with some rain, and quieter streets than in summer, which suits travellers who want the stone city without the crowds. Some seafront restaurants close for the season, so we plan meals and sightseeing around the venues that stay open. Dubrovnik holidays are a natural starting point for a winter stay on the coast.
• Korcula: Korcula is a walled island town reached by ferry from Orebic, and it tends to keep a gentler climate than the inland north. Its harbour and narrow lanes are calm in December, and the island's southern position means the coast often feels a little milder than the mainland. Ferry frequencies drop in winter, so journeys need planning around the reduced timetable and the weather at sea. We recommend it for a slow, quiet stay where the pace of the town matters more than long sunny beach days. Croatia holidays built around island towns like this suit travellers who value calm over crowds.
• Mljet: Mljet lies off the southern coast and is reached by ferry from the nearby mainland port, and its national park is wooded and sheltered from the strongest winds. The forest and saltwater lakes stay green in winter, and walks are pleasant on dry days even when the sea is too cold for swimming. Ferry links are less frequent outside the summer, so a December visit needs firm transport arrangements. It is a good choice for walkers who want mild, quiet scenery rather than a busy resort with open beach bars.
• Trogir: Trogir is a small medieval old town on an island just across from the Dalmatian mainland city, and its historic centre is compact and easy to explore on foot in winter. The town is a short drive from that neighbouring city and shares the same moderate coastal climate, so days are usually cool but rarely harsh. Many cafés and restaurants reduce their opening hours in December, which makes the town feel calm and reflective. We suggest it for travellers who want the Dalmatian coast in winter with a gentle pace and a historic setting, the same brief our Cheap Croatia Holidays deals are built around.
• Hvar: Hvar is among the sunniest places in Croatia, and its position in the central Adriatic gives it some of the best winter sunshine on the coast. The harbour and fortress views are strong on clear days, although the island's bars and clubs largely close outside the summer. Crossings from the mainland port run less often in December, so timing the sailing matters. Hvar holidays are a strong pick for a sunny winter walk, but we would advise planning around limited evening entertainment.
