The average temperature along the coast is from 5-10°C in winter; 26–30°C in summer. The sea temperature in winter is 12°C, and around 25°C in summer.
Main winds in the Adriatic
- maestral (northwesterly)
- bura (northeasterly)
- jugo (southeasterly)
The maestral is a northwesterly wind that appears in periods of high air pressure, usually around 11a.m. and brings good weather. It can reach a force up to 5 and causes rough seas. It dies down in the late afternoon, and the following day – after a calm night – starts blowing at a similar force as the previous day.
Burin is a wind that blows from the opposite direction of the maestral. It usually blows at night, mostly from the north, northeast in the northern Adriatic, and from the east or southeast in the southern Adriatic. It is strongest before dawn and soon dies down afterwards.
Bura is a strong northeasterly wind that appears in periods of high air pressure, it blows from the mainland towards the sea in powerful gusts. It is hardly predictable in spite of early warning: the coastal mountain peaks are covered by small clouds and the sea surface in the northeastern part spumes. The greater the distance from the coast, the weaker the force of gusts is. In the summer the bora usually blows only a few hours, but sometimes it can last up to a day or two. It can be extremely strong in the Kvarner area, along the Velebit Channel, and around Šibenik, Split, Pelješac and Dubrovnik.
Jugo (scirocco) is a warm and humid southeasterly wind that from October to the end of January brings a lot of rain. Calm sea and a heavy cloud cover in the south are signs of the jugo slowly approaching and raising high waves. The jugo often blows for several days (in summer up to 3 days, in winter up to 3 weeks), while rough seas can last a longer period. From time to time this wind also brings the reddish-brown sand from Africa. It should be remembered that the jugo can change its direction in just a few minutes and turn into a very strong bora (northeasterly wind). The jugo is a typical wind of the Southern Adriatic where it lasts longer than in its northern part.
Nevera is a very strong westerly wind that brings bad weather. It mostly blows in summer. It strikes suddenly and vehemently making the sea rough, but mostly lasts shortly. It is usually accompanied by thunder. When its stops blowing the air is fresh and pleasant. It is most common in the Northern Adriatic.
Other winds in the Adriatic are: lebić – southwesterly, levant – strong southeasterly, tramontana – cold northerly.
High and stable air pressure usually brings winds that during the night blow from the mainland, and daily winds that blow from the sea.
