Zadar is the oldest continuously inhabited Croatian city. It is situated on the Adriatic Sea, at the northwestern part of Ravni Kotari region. Zadar serves as the seat of Zadar County and of the wider northern Dalmatian region. The city proper covers 25 km2 (9.7 sq mi) with a population of 75,082 in 2011, making it the second-largest city of the region of Dalmatia and the fifth-largest city in the country.
Zadar faces the islands of Ugljan and Pašman (part of the Zadar Archipelago), from which it is separated by the narrow Zadar Strait. The promontory on which the old city stands used to be separated from the mainland by a deep moat which has since been filled. The harbour, to the north-east of the town, is safe and spacious.
Zadar has a borderline humid subtropical (Cfa) and Mediterranean climate (Csa), since only one summer month has less than 40 millimetres (1.6 in) of rainfall, preventing it from being classified as solely humid subtropical or Mediterranean. Zadar has mild, wet winters and very warm, humid summers.

Šibenik is a historic city in Croatia, located in central Dalmatia, where the river Krka flows into the Adriatic Sea. Šibenik is a political, educational, transport, industrial and tourist center of Šibenik-Knin County, and is also the third-largest city in the Dalmatian region. As of 2011, the city has 34,302 inhabitants, while the municipality has 46,332 inhabitants.
Unlike other cities along the Adriatic coast, which were established by Greeks, Illyrians and Romans, Šibenik was founded by Croats. Excavations of the castle of St. Michael, have since proven that the place was inhabited long before the actual arrival of the Croats. 
Šibenik has a mediterranean climate (Csa), with mild, humid winters and hot, dry summers. January and February are the coldest months, July and August are the hottest months. In July the average maximum temperature is around 30 °C (86 °F).
