complex, composed of carbonate, siliciclastic and evaporite rocks of different ages, ranging from Triassic (approx. 220 mil. years ago), through Miocene (approx. 10 mil. years ago), to Quaternary (recent deposition). Climate Palagruža has a weather station, established in 1894, which represents a major indicator of weather, especially wind, waves and precipitation on the open Adriatic. Weather conditions on the central Adriatic are dictated by movements of low-pressure area, which causes frequent changes of bora and scirocco (jugo) winds. Annually, Palagruža Island has 104 days with strong (6-7 Bf), and 21 days with stormy winds (>8 Bf). Due to its remote position in the middle of the sea, Palagruža exhibits more Mediterranean climate features than the Croatian coast. Summers are sunny and dry, while most of the rain falls in winter months. There are 2620 sunshine hours annually (1961–1990 average). Annual precipitation level of is the lowest of all Croatia. Maritime winds temper air temperatures compared with the mainland, with average summer daily highs of ; on the other extreme, winter average daily lows are .
