Jugo is a humid and warm wind, which often brings rain and bad moods to local people. Usually, it does not blow strongly, but sometimes it may cause problems in ferry traffic to the mainland.
Mild winter sent away by the wind
During winter time temperatures rarely drop below zero degrees Celsius (32°F) and snow may appear once or twice a year on Vidova Gora, the highest peak of the island Brač.
Winter on the island is marked by a north wind called Bura. It is a dry, cool wind, so if you feel very cold on a sunny cloudless day that’s Bura. It can be very violent, causing traffic problems such as closed highways and airports and ferries locked at the harbours. Although it may sound scary, the locals love Bura as it brings chilly and fresh air and you should definitely experience life on an island when it is cut off from the mainland for a few days.
