Island Korcula and also
whole area of south Dalmatia are characterised by a very favourable
climate. The temperature in January lies on an isotherm of
7oC and 8oC, in an area with a distinctive
mediterranean climate; a mild, mostly moist winter and a dry, hot and
sunny summer.
This area is one of the
sunniest parts of the central and northern Mediterranean, characterised
by an extremely bright sky with about 2701 sunny hours per year, and a
high daily average of 7,35 sunny hours per day. In the summer, it rises
even to an average of 11,3 hours, 7,4 hours in the spring, 6,3 hours in
the autumn, and 4,2 hours in the winter.
This high rate of sunny
weather has an influence on the relatively high yearly and daily
temperature of the air. A medium January approximate of 7,8o
makes this area the warmest part on the Mediterranean northern coast. On
island Korčula the temperature very occesionally drops below
0oC; on the other hand, more than a hundred days have a
temperature of more than 25oC, and more than fifty days above
30oC. The settlements on the western and southern coast of
the island have the hottest climate. So, with some other settlements
Karbuni have the hottest climate.
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 22,6o C, that is, an average yearly
approximate of 17,5oC.
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 the
"bura" (north-east wind), which show up during the entire year, but
especially well marked during the winter, when their bioclimatic
activity is at it's peak. In the early spring and summer, the most
characteristic wind is the Maestral which has important thermoregulation
activity, because as it is a sea wind, it brings a favourable
coolness.The Maestral is replaced by the night breeze from the north
(burin), which cools the overheated dry land. Also in summer blow some
other winds: tramontana (northwest), levant (eastern) and lebic
(western), but they are less frequent.
Rainfall on the this area
also has Mediterranean characteristics. The wettest mounths are November
and December and driest July and August. It amounts to only 809 mm
yearly, but it is favourably dispersed, so that the spring and
especially the summer is mostly dry, while moderate rains fall in autumn
and winter season. Snow is an exceptionally rare
phenomenon.
