Bora is cold, downward wind blowing on bursts from north-northeast to east-northeast. The strength of Bora is explained by the existence of the warm air above the sea surface and cold air above the mountain ranges in the littoral which cause the strong air flow.

Along the east coast, protected from bora are the west coast of  Istria, leeside of the island Unije, leeside of the island Dugi otok, land under shore in Zadar channel, leeside of Kornati and leeside of the island Mljet. Bora blows mostly in winter. In summer, it usually lasts only one day or a couple of hours while in winter it can blow for days.


Sirocco is a warm and moist wind which blows from the direction east-southeast to south-southwest. Its consequences are high waves and rain. Sirocco is a characteristic wind for the southern Adriatic, where it blows longer and stronger than in the northern part. The signs of the oncoming sirocco are the calm at the sea, weak changeable winds, dimness of the horizon, the increase of the temperature and moisture, and the gradual decrease of the pressure. Sirocco, as opposed to bora never blows at sudden but develops slowly.

Landward breeze (mistral)

Mistral is a daily, thermic wind blowing from the direction of the northwest and it occurs as the consequence of the difference in the speed of warming up of the land and the sea. It is present from the spring to the autumn, and, during the day, it often changes the direction of blowing. It is more noticeable at the southern Adriatic than at the north. In the afternoon, it can reach the speed of 20 to 35 knots which is especially visible at Bol, the island Brac and Viganj at Peljesac, the areas mostly visited by the surfers.

The stiff breeze (burin)

Burin is a wind blowing contrary to the landward breeze. It blows during the night from the direction of the north, north-east in the northern Adriatic, and in the southern Adriatic, from the east or south-east.

Sudden storm

Sudden storms are thermal, swirl storms which emerge with high speed from the open sea (west). The last shortly and have great strength. They occur mostly in summer, usually at the northern Adriatic and are accompanied with thunderstorms. The signs of oncoming storms are the development of the white cumulus and higher and darker cloud which top starts spreading in a line. Before the storm arrival, there is a silence. Usually the storms appear after several weeks of sultriness, warm nights and dimness of the horizon.
