Local winds (bora, mistral, sirocco) are characteristic, affecting the air temperature. The water temperature from north to south varies from 24 to 26 degrees in August and from 7 to 13 degrees in February. The salinity of the water ranges from 33 to 38 ppm. Irregular semi-daily tides (up to 1.2 m). Summer is dominated by clear weather with pronounced breezes, which is occasionally replaced by rare storms, and winters are cloudy and rainy (up to 70% of the annual precipitation).

In autumn, the sea cools down to + 11 + 13 degrees. In winter, the water temperature in the Adriatic Sea never drops below 6-8 degrees. There are frequent storms in winter. Most of the annual precipitation falls.

Mistral begins to gain strength, usually at 9-10 am from the southeast, changing its direction to the west. Locals describe it as «the wind following the sun.» On the high seas, it gains strength to a maximum of 20 knots, but at headlands and canals it develops high speed.
