City of Kaštela is situated in the middle of east Adriatic coast, so the climate is fully shared with the rest of the Mediterranean region. Mildness of the climate is the main characteristic of this area and makes Kaštela one of the sunniest parts of Adriatic.
We offer you almost 2700 hours of sunshine a year and crystal clear sky under which on the slopes of mountain Kozjak all the way to the coast, you can find numerous vineyards, as well as olive, cherry, orange and tangerine plantations. Cultivated, mostly coniferous parks on the shores are sun shined on average whole 7 hours a day.
During the fall and winter the climate is also typically Mediterranean. On average 809 mm of rain falls during the winter and autumn season. The average annual temperature of the air is 19,2°C and of the sea is 17,5°C.
SPRING: The average air temperature is 17,5°C. Spring is the period of ever changing winds and the weather is mostly sunny and dry. In the end of the spring and the beginning of the summer the fragrance of the Mediterranean herbs is starting to spread by the thermal western or northwestern wind called Maestral. Average day insolation is 7,4 hours.
SUMMER: The average air temperature is 25,8°C. Summers are mostly hot and dry. Steady thermal wind - Maestral that blows across the sea from the west and northerly night wind called Burin are excellent temperature regulators that cool the land heated by summer sun. Average day insolation is 11,3 hours, and average sea temperature is 24°C.
AUTUMN: The average air temperature is 14,5°C with temperate rain periods and constant wind exchanges between Jugo(SE) and Bura(NE). Average day insolation is 6,3 hours. Early nightfall in combination with frequent winds create a real challenge for every sailor in the bay.
WINTER: The average air temperature 12°C. Frequent exchange of the winds Jugo and Bura in this period is at its peak, causing sudden exchanges of sunny and rainy weather. Average insolation is 4,2 hours a day, which makes a mild winter. In the mid January for example, the average temperature is as high as 7,8°C . That makes this area the wormiest part of the north Mediterranean coast. The average sea temperature is 13°C. In this area the snow is a real rarity.
here are three characteristic weather patters in the Bay of Kaštela area, and can also be applied to the whole eastern Adriatic coast:
The winds Jugo and Bura and their ethernal exchanges almost entirely mark the weather on the Adriatic.
Strong, sudden, dry, cold and sometimes hurricane strength wind (up to 12 on the Beaufort scale). Blows in strong gusts from cold mountainous regions of east Adriatic coastline often from NNE to ENE direction. Configuration of the land creates both the direction and intensity of the wind.
Bura savagely crushes on the sea surface and creates short, irregular, steep and mostly low waves (1-2,5m). Strong Bura blows away the crest of the waves and creates a thick vapour from small particles of saltwater that can reduce visibility thus cause shipwrecking and is also dangerous for people because it can be difficult to breathe since the vapour can easily be inhaled.
The temperature of the air can plummet in a very short period of time for over ten degrees. The air pressure usually rapidly rises. Bura blows more often, stronger and for longer in wintertime (3-7 days), it is rare, weak and short in summer (2 days).
As you get farther from land, Bura gets weaker and with less gusts but the waves get much bigger.
Sudden appearance of the bura is one of her most dangerous characteristics.
Cyclonic, "dark" bura is very strong and constant wind without gusts, blows from direction NE-E. It is followed by dark, cloudy, rainy weather. In winter often accompanied by sleet, sudden pressure and temperature fall.
It's a more benign type of Bura. Blows from north. It is local, cold and dry, short-term wind (usually one day), but not so strong (9Bf) and gustily as bura.
It is followed with sunny weather and high pressure, the further from the coast the stronger it gets and the waves get higher.
It is stronger in the south parts of the Adriatic.
Eastern wind, short-termed, blows steadily, without gusts (7Bf).
It is a wind which blows during transition when jugo changes to bura or vice versa.
In winter it is often followed by rainy weather, low temperatures sometimes even snow.
In summer during sunny and stable weather sometimes it blows in the early morning through channels in between the mid-Dalmatian islands.
Southeastern wind, warm, damp, blows steady in both the direction and strength, and without gusts. Blows most frequent from the east-south-east direction (Jugo-Levanat), south-east (Jugo-Sirocco) and south (Oštro) direction. It builds up wind speed gradually and can get hurricane strong after 2-3 days. It blows more often and stronger on the east than on the north Adriatic coast.
It blows strong on the open sea, but nearing the coast it gets weaker.
Cyclonic "dark" Jugo is specific for its thick, dark gray, low and heavy clouds pouring rain non-stop, followed by thunders. Sometimes blows in gusts.Air pressure is low and stirred sea interferes with visibility.
Other type of jugo blows on sunny and clear weather with little or no clouds. It appears more often in spring and autumn periods. High tide and rise of atmospheric pressure are its characteristics.
Stormy wind (12Bf) that blows from the south-western direction, carrying showers, creating huge waves and lack of visibility. Particularly strong during winter and autumn, and because of its huge waves and sudden appearing it is dangerous for unprepared and unprotected boats.
Western wind. Rare, transient, short-termed, cold and dangerous, can be strong up to 12Bf. Brings short but abundant rain.
Northwest daily thermal wind typical for the summer period. Pleasant and fresh, weak to medium in intensity (6Bf). It is a friend of nice and sunny weather, mitigates the summer heat, brings low pressure. It blows very steady so it is particularly suitable and pleasant for windsurfers. It blows stronger and more often in south parts of the Adriatic coast. From morning till sunset it changes direction from east to northwest (it follows the sun) creating tall and regular waves.
Thermal opposite of Maestral that blows in summer nights after sunset from the continent towards the sea. Usually lasts whole night and can be mistaken with bura, because of it's strength. It can blow as far as 15 nm out to open sea. Its direction on the south Adriatic coast is towards east. Brings nice weather and high pressure.
Besides winds, Adriatic coast is known for local, short-termed weather storms called Nevera. They can happen during the whole year but most often they appear in summer. Their characteristics are strong rain, lightening, thunder and temperature falling.SIGNS OF BED WEATHER:
