Climate of the City
of Omiš, Croatia
Due to a mountainous range covered with thick pine woods that reach to the very beaches, Omiš has a mild Mediterranean climate with mild and rainy Winters and warm and dry Summers with a large number of sunny hours annually.
This region boasts very clear skies. There is an average of 2700 hours of sunshine, i.e. a daily average of 7.3 hrs. In Summer, it rises even to an average of 11.3 hours, 7.4 hours in Spring, 6.3 hours in Fall, and 4,2 hours in Winter.
This high rate of sunny weather has an influence on the relatively high yearly and daily temperature of the air. The average air temperature is 16.0oC (61oF). January is in average the coldest [7.7oC (46oF)], and July is the warmest [25.6oC (78oF )] month of the year. That is why the coastal part of Central Dalmatia is one of the sunniest regions of the central part of the northern Mediterranean.
This favourable climate and the flow of warm sea currents have an influence on the high temperature of the sea, with a Summer average of 22.6oC (73oF), that is, an average yearly approximate of 17.5oC (64oF).
The local and periodical (seasonal) winds also help to
maintain a favourable climate. Among them, the most distinct are the local winds
"Jugo" (south-east wind) and "Bura"
(north-east wind), which show up during the entire year, but especially well
marked during Winter, when their bio-climatic activity is at it's peak. In the
early Spring and Summer, the most characteristic wind is "Maestral"
which has important thermoregulation activity, because as it is a sea wind, it
brings a favourable coolness. "Maestral" is replaced by the
night breeze from the north ("Burin"), which cools the
overheated dry land.
Rainfall on the this area also has Mediterranean characteristics. It amounts to
only 809 mm (32 in) yearly, but it is favourably dispersed, so that Spring and
especially Summer is mostly dry, while moderate rains fall in Fall and Winter
season. Snow is an exceptionally rare phenomenon.
