Weather in Croatia in September

The warmest conditions in September are usually found on the southern Dalmatian coast and the islands, where summer heat lingers longest.

• Dubrovnik: Dubrovnik enjoys warm, settled September weather, with the sea typically at its warmest for swimming just after the peak summer months. The walled old town is pleasant to walk in the cooler morning and evening hours. Daytime heat can still be strong on the stone streets, so planning sightseeing for early in the day makes sense. For a warm southern coast with a historic setting, Dubrovnik holidays suit a September trip well.
• Hvar: Hvar is typically one of the sunniest spots along the Croatian coast in September, with long dry days and a warm sea that stays comfortable for swimming well into the month. Ferry links from the mainland port city make it easy to reach by day trip or as a longer stay. The trade-off is that the harbour and bars remain busy, so booking accommodation early helps. For a sunny seaside base with a lively town, Hvar holidays are hard to beat.
• Korcula: Korcula sits among the warm southern Dalmatian isles and typically keeps mild, sunny September conditions that suit a slower pace, the same kind of brief our Croatia All Inclusive Holidays deals are built around. Ferries from Orebic and the historic walled city on the coast make it straightforward to reach, and the walled town on the water is calmer than the busier stops. Options for shade are fewer on the open shoreline, so a hat and water matter on hot afternoons. Korcula is a good choice if you want warmth with a quieter atmosphere.
• Brac: Brac is one of the larger isles in the Adriatic, reached by ferry from the mainland port city, and it tends to enjoy warm, dry weather through September. Its beaches and sheltered coves hold heat well, which makes the destination appealing for a relaxed beach stay, the same brief our Croatia Adults Only Holidays deals are built around. The landmass is more spread out than a compact town, so you will want transport to explore beyond the resort area. For a warm sea-bound break with easy ferry access, Brac is a sensible choice.
• Split: Split is a warm, lively base on the central Dalmatian coast, with September weather that is typically sunny and dry. The waterfront stays warm into the evening, making it pleasant for dinner outdoors. For warm weather with a working city and good transport links, Split works well.
