Summer temperatures in July will be about 34C in the northern part, while in the southern part they will rise even to 38C. In the winter, the coldest temperatures are noticed in the northern Adriatic (up to -16C), while they will not have exceeded -6C in the southern part.
On the Adriatic Sea, the bora, sirocco and north-western wind blow most often.
Bora (Cro: bura) is a dry, cold downward wind blowing in bursts from the north-northeast to the east-northeast direction. The direction in which the wind blows is primarily influenced by the configuration of the shore. The strength of the bora is explained by the existence of warm air over the surface of the sea, and a cold layer of air above mountain ranges in the littoral, which cause a strong streaming due to equating of the pressure. Cold air tends to fill the void which occurs due to the rising of the warm (lighter) air from the sea surface. The bora blows mostly in the winter, during January - March. In the summer, it usually lasts for a day or several hours.
The sirocco (Cro: jugo) is a warm and moist wind which blows from the direction east-southeast to south-southwest. Its causes are high waves and rain. The sirocco is a characteristic wind of the southern Adriatic, where it blows longer and stronger than in the northern part. In the summer, it usually blows for up to 3 days, or less. The signs of the oncoming sirocco are a calm sea, weak changeable winds, haziness of the horizon, an increase in the temperature and moisture, and the gradual decrease of pressure. Waves from the southeast become larger.
• Landward Breeze
The landward breeze (Cro: maestral) is a daily, thermic wind blowing from the northwest. It is present from the spring to the autumn, and, during the day, it often changes direction. The landward breeze is more present in the southern Adriatic than in the northern Adriatic.
• Stiff Breeze
The stiff breeze (Cro.: burin) is a wind blowing contrary to the landward breeze. It blows during the night from the north, north-east in the northern Adriatic, and in the southern Adriatic, from the east or south-east. It is strongest before dawn, and it stops soon after.
