The city of Kaštela is located northwest of the city of Split, west of Solin and east of Trogir, on the central Dalmatian coast. This region enjoys a mild Mediterranean climate, with sunny weather throughout the summer. The city of Kaštela enjoys almost 2700 hours of sunshine a year. Under the crystal and clear sky you can find numerous vineyards, as well as olive, cherry, orange and tangerine plantations on the slopes of Kozjak Mountain. The sun shines on average 7 hours a day. The average rainfall during the winter and autumn season is 809mm. The average annual air temperature is 19,2°C while that of the sea is 17,5°C.
SPRING: The average air temperature is 17.5°C. During the spring the weather is mostly sunny and dry with constantly shifting winds. A thermal western or north western wind called Maestral starts to spread the fragrance of the Mediterranean herbs at the end of spring and the beginning of summer. The sun shines on average 7.4 hours a day.
SUMMER: The average air temperature is 25.8°C. Summers are mostly hot and dry. A steady thermal wind called Maestral blows across the sea from the west and a northerly night wind called Burin are excellent temperature regulators that cool the land. The sun shines on average 11.3 hours a day, and the average sea temperature is 24°C.
AUTUMN: The average air temperature is 14.5°C with moderate rain periods and constant wind shifts between Jugo(SE) and Bura(NE).The sun shines on average 6.3 hours a day. Night falls early and, in combination with frequent winds, creates a real challenge for every sailor in the bay.
WINTER: The average air temperature is 12°C. Frequent wind shifts between Jugo and Bura cause sudden exchanges of sunny and rainy weather. The sun shines on average 4.2 hours a day. Winters are mild in this region. For example, in mid-January the average temperature can get as high as 7.8°C. That makes this area the warmest part of the northern Mediterranean coast. The average sea temperature is 13°C. In this area the snow is a real rarity
There are three characteristic weather patterns in the Kaštela Bay area. Also, we find the same patterns along the whole length of the eastern Adriatic coast:
- moist, cloudy and unstable weather accompanied by a southern relatively warm and moist wind called Jugo (pronounced YOU-vertiGO)
- dry, sunny and mostly stable weather accompanied by a northern cold and dry wind called Bura (pronounced BUsh-RAvine)
- stable summer weather accompanied by a north-western wind called Maestral (pronounced MArge-rEd-STRong-ALghorithm) and a nightly northern wind, blowing from the mainland, called Burin (pronounced BUsh-RINg).
Jugo and Bura are unique to the Croatian coast.
BURA Bura is a strong, sudden, dry, cold and sometimes hurricane force wind (up to 12 on the Beaufort scale). It blows in strong gusts from the cold mountainous regions of the eastern Adriatic coastline often from a NNE to ENE direction. The configuration of the land determines both the direction and intensity of Bura. Bura savagely pounds the surface of the sea and creates short, irregular, steep and mostly low waves (1-2.5m). When Bura is strong it blows away the crest of the waves and creates a thick vapor from small particles of saltwater and this can reduce visibility and cause shipwrecks. It is also dangerous for people because it can be difficult to breathe since the vapour can easily be inhaled.
Air temperature can plummet rapidly by more than ten degrees. Air pressure usually rapidly rises. Bura blows more often and it is stronger and longer lasting in wintertime (3-7 days). It is rare, weak and short during the summer (2 days). Farther offshore, Bura gets weaker with fewer gusts. However, the waves get a lot bigger. One of the most dangerous characteristics of Bura is the wind’s sudden appearance.
“”Dark”” Bura is a cyclonic, very strong and constant wind without gusts. It blows from the NE-E direction.
It is followed by dark, cloudy, rainy weather. During the winter it is often accompanied by sleet and sudden drops in air pressure and temperature.”
TRAMONTANAPronounced TRAp-MONTANA. It’s a weaker version of Bura. It blows from the north. It is a local, cold and dry, short-lasting wind (usually one day), but not so strong (9Bf) and gustily as Bura. It is followed by sunny weather and high air pressure. It gets stronger offshore, and it creates high waves. It is stronger in the southern part of the Adriatic.
LEVANAT Pronounced LExus-WAtt-ghaNA-raT, It is an eastern, short-lasting wind. It blows steadily without gusts (7Bf). It blows during the transition Period when Jugo changes to Bura or vice versa. During the winter it is often followed by rainy weather, low air temperatures and sometimes even snow. During the summer it sometimes blows in the early morning through the channels that separate the central Dalmatian islands if the weather is sunny and stable.
JUGOJugo is a south-eastern wind, warm and damp. It blows steadily in terms of both direction and strength, and without gusts. Usually it blows from the east-south-east (Jugo-Levanat), south-east (Jugo-Sirocco) and south (Oštro). It increases its speed gradually and it can turn into a hurricane force wind after 2-3 days. The wind is stronger in the southern Adriatic than it is in the northern Adriatic. Also it is stronger offshore than it is along the coastline.
Cyclonic “”dark”” Jugo: it is characterized by thick, dark grey, low and heavy clouds, heavy continuous rain and thunderstorms. Sometimes it blows in gusts. Air pressure is low and the sea is rough, creating reduced visibility conditions.
Anticyclonic Jugo: it blows when the weather is warm, humid, sunny and clear. It blows more often during the spring and autumn. It is characterized by high tides and rises in atmospheric pressure. ”
LEBIĆ (garbin) Pronounced LEg-BITCH. Lebić is a stormy wind (12Bf) that blows from the south-west, carrying showers and creating huge waves. It also reduces visibility. It is particularly strong during the winter and autumn, and because of its huge waves and sudden appearance it is dangerous for unprepared and unprotected boats.
PULENAT PULl-ENter-ATmosphere. It is a westerly wind. It is rare, short-lasting, cold and dangerous, and can reach up to 12Bf. It brings short spells of heavy rain.
MAESTRAL It blows from the north –west. It typically occurs during the daytime in the summer months. It is pleasant and fresh, its force is weak to medium (6Bf). Depending on the locality, it blows from the north-west or south-west. It brings low air pressure. It blows very steadily, so it is particularly suitable and pleasant for windsurfers. It is stronger and more frequent in the southern region of the Adriatic coast. It changes direction during the course of the day, that is to say, it follows the sun. It creates high and regular waves.
BURIN It blows from the coast during the night. It appears on both sides of the Adriatic. It is a light breeze and it occurs after sunset. Usually it blows until dawn and sometimes it can be as strong as Bura. It reaches as far as 30km offshore. It blows towards the east in the southern region of the Adriatic coast. It brings nice weather and high air pressure.
NEVERA The Adriatic coast is known for its winds, but it is also known for local, short-lasting storms. These storms are called Nevera or Neverini. They occur all year round, but they are most frequent during the summer. These winds are characterized by strong gusts of wind (15-20 cv), heavy rain, lightning, thunder and drops in air temperature.
SIGNS OF BAD WEATHER:
- sudden drop in atmospheric pressure
- extremely high tides
- absence of Maestral during the summer, or if it unusually stops before the usual time
- if the moon is pale and if there is a halo around the moon that means the weather will change
- if the Sky is red in the morning or if a rainbow appears early in the morning that means that it will start raining soon
- strong wind in the morning, during nice weather
- if a Maestral-like wind blows during the winter, that often means that there will be Jugo and rain
- if Bura shifts to an easterly or south-easterly direction, during clear weather
- if there is a gray cloud bank in the west, especially in the evening
- if the sun is pale-yellow before sunset
- if there is a halo around the sun or the moon and if there is a moist wind
- constant low air pressure during bad weather means that the weather conditions will probably continue for a longer period of time
SIGNS OF NICE WEATHER:
- Progressive rise in air pressure (especially above 1012 hPa)
- clear sky on the western horizon during cloudy weather
- in principle: wind after rain brings nice weather
- if the sky is red after sunset during cloudy weather
SIGNS OF PROLONGED NICE WEATHER:
- Maestral during the day, Burin until down
- extremely low tides
- clear sky and no wind
- clear and colourful sunset during nice weather
- no change in high pressure
- while Bura blows the weather cannot worsen
