Main settlements on the island are towns of Korčula, Vela Luka and Blato. Villages on the coast are Brna, Lumbarda, Račišće, Zavalatica, Prižba and Prigradica, while Žrnovo, Pupnat, Smokvica and Čara are placed inland. The island is divided into municipalities of Korčula, Smokvica, Blato and Lumbarda.
The climate is Mediterranean; an average air temperature in January is 9.8 °C (49.6 °F) and in July 26.9 °C (80.4 °F); the average annual rainfall is 1,100 mm (43.3 in). The island is largely covered with Mediterranean flora including extensive pine forests.
The main road runs along the spine of the island connecting all settlements from Lumbarda on the eastern to Vela Luka on the western end, with the exception of Račišće, which is served by a separate road running along the northern coast. Ferries connect the city of Korčula with Orebić on the Pelješac peninsula and Drvenik on the mainland (near Makarska). Another line connects Vela Luka with Split and the island of Lastovo. Fast passenger catamarans connect those two ports with Split and the islands of Hvar and Lastovo.
The main Adriatic ferry line connects Korčula with Dubrovnik, Split, Zadar and Rijeka and in summer there are direct ferries to Italian Adriatic ports.
