Weather

The weather in the Adriatic is influenced by cyclones and anticyclones over the middle and south Adriatic. The usual direction of cyclones over the Adriatic is from west to east. On their front side they bring winds south direction (then jugo blows mostly along the Adriatic Sea), while in the Adriatic, this means the flow of warm and moist air so the weather is cloudy and rainy.
Following the cyclone, with the growing of anticyclone and its expansion across the European  continent to the east, the wind turns north-eastwards and brings cold and dry air, wind dissipats the clouds, followed by the weather stabilization.
The weather on the Adriatic Sea is characterized by stabilization of time thereafter, when the sunny and calm weather prevails. In summer there is a caracteristic mistral breeze till new cyclone comes and weather cycle on the Adriatic repeats.
This rhythm of change in weather conditions is common in the Adriatic, and differs only by how often and from which direction the cyclones come.

For safe navigation on sea the regular monitoring of weather forecasts is recommended.
