Vis is in the southwest part of the bay. The port is protected from the open sea's influence by the islet Host (named after William Hoste) and the peninsula Prirovo (sometimes spelled "Prilovo"). Other, smaller ports are in Kut and Stonca, which are also parts of the town of Vis. Vis is separated from its hinterlands (Dračevo polje and Velo polje) by 250–300 m high hills which are important for local residents as the main source of income from viticulture. Other official parts of the town are villages on the bays of the south and southeast coast, such as Milna, Rukavac, Srebrna, Stiniva, Stončica, some of which show signs of developing into new towns. Besides Vis itself, these bays and villages are the island's main source of tourist income. Climate Vis experiences warm and temperate winters with warm to hot summers. The landward breeze makes it the most moderate climate in Croatia. The climate allows for tropical and Mediterranean vegetation, including palms, carobs, olives, grapes and lemons. The average rainfall is about per square meter. The island of Vis has a number of natural sources of drinking water from natural spring water reservoirs. It is also home to 12 distinct types of island vegetation. The World Organization for Environmental Protection has named Vis one of the 10 environmentally best-preserved islands in the Mediterranean. Administration The official area of the town of Vis is the entire eastern half of the island. The western half is under the authority of Komiža. The Vis region comprises eight villages: Dračevo Polje, Marine Zemlje, Milna, Plisko Polje, Podselje, Podstražje, Rogačić and Rukavac. The town council consists of eleven councilors divided into three groups; five from the SDP - HNS - HSS coalition, three from the Independent List of Ante Acalinović and three from the HDZ - HSP coalition. Ascendancy is currently held by HDZ - HSP coalition in alliance with the Independent List. Population Economy Until the middle of the twentieth century, the main sources of income were vineyards and wine production. In recent times, more and more people have been working in tourism.
