    warm seas. The surface temperature in summer 
    amounts to 23-25°C. The temperature of even the deepest waters is not below 
    11-13°C. At the depth of 70 metres the temperature is 18-19°C. 
    In winter, the surface temperature amounts to 14-16°C, and only exceptionally it falls 
    to l2°C. Then the southern Adriatic is warmer than the northern Adriatic. The 
    difference varies between 8°C and 10°C. 
    In spring the sea begins to get warmer and it soon reaches the temperature of 
    16-22°C. In summer- the sea is colder than the air and it prevents a more significant 
    warming. In winter being warmer than the air, the sea warms up the air. Thus it 
    moderates both summer and winter. One interesting point is that in total the sea is 
    warmer, than the air- by 1°C - 3°C. 
      
      
    The transparency is great, smaller close to the
    shore, greater in the open sea. It is 
    the smallest in the northern Adriatic (5-39 meters), the greatest in the southern 
    Adriatic (16-56 metres). In the channels it reaches 10-30 metres. The colour of the 
    Adriatic,, sea is from light blue to deep blue, of a high intensity and various shades. 
    The water, is clear with an abundance of colours varying in the course of the day, 
    under the influence of the sun, the clouds and the winds, from, yellow, green, light 
    blue to deep blue, and together with a great transparency, it offers a memorable 
    experience. 
    In this clean and crystal-clear sea live 365 species of fish of which 112 species are 
    edible. Numerous families of mollusks, shells, sponges, algae and crabs live on the 
    seabed. One must not forget that this is the Mediterranean, which means that all of 
    them are of the highest quality and afford an inexpressible visual experience of 
    forms, colours and ways of living.

            The Adriatic has the Mediterranean 
            climate characterized by clear, warm and dry 
            summers and mild and humid winters. The transitional seasons spring 
            and autumn 
            have the characteristics of both summer and winter. The Adriatic is 
            often influenced 
            by different, often adverse, climatic and weather conditions. The 
            diversity and 
            frequent changes of the weather have a very favourable impact on the 
            life and 
            activities of the people and make the Adriatic ever more interesting 
            and more 
            attractive to those sailing it. 
            The temperature of the air is Mediterranean mild. The sea has a very 
            favourable 
            impact on the air temperature. In winter it warms up the air arriving 
            from the 
            mainland, and cools the hot air in summer. The mean air temperatures 
            the Adriatic 
            ranges from 14°C in the north to 18°C in the south which means the 
            progressing 
            south the temperature rises. In the northern area of the Adriatic 
            the mean 
            temperature is 2°C (the estuary of the PO) while the central and southern 
            parts it is 
            above 10°C. 
             
              
             
            On the east Croatian coast the temperature of the air is more than 
            2°C higher than on 
            the coast of southern France, and 3°C higher than on the west Adriatic, 
            the Italian 
            coast, though all the three are on the same latitude. In summer the 
            strong heat is 
            softened by the fresh sea-breeze, the "maestral". In summer, 
            in July, the mean 
            temperature ranges from 22 to 25°C. Autumns are warmer than springs.The 
            highest 
            temperature rarely surpasses 33°C-35°C, the lowest ones never falling 
            below 5°C. 
            On the sea and on the islands the differences in temperature are even 
            smaller, the 
            Iowest level only exceptionally falling below 0°C. 
      
    The Adriatic area ranks among the areas with the
    highest rate of insolation. As 
    regards the summer clearness of the sky the central Dalmatian islands and the 
    southern part of the Croatian coast absolutely rank among the most clear-weather 
    regions of Europe. The central part of the Adriatic has the highest rate of insolation, 
    slightly higher on the open sea and on the islands than on the coast. Insolation in 
    hours per year are: Trieste 2205, Mali Losinj 2248, Sibenik 2572, Split 2697, Hvar 
    2715, Dubrovnik 2584.Insolation is at its highest in summer, at its lowest in winter. 
      
    Different parts of the Adriatic greatly differ
    as regards the quantity of precipitation. 
    The mean quantities of precipitation per year vary from 420 mm in the open sea to 
    4626 mm in the elevated areas on the mainland. It is more abundant along the 
    coastline than on the islands and the open sea. Precipitation is most abundant in 
    autumn or winter. slightly Iess abundant in spring. Summer rains are very rare, with 
    the first rains in late August, and then usually associated with thunderstorms. Snow 
    on the Adriatic is a rarity. If snow does fall it does not keep on the ground.  |
