MURTER - CROATIA
Winds, currents and waves
The Adriatic Sea is a semi-closed Sea,
characterized by intense cyclone
activities (especially in winter), when
winds blow in different directions and
Adriatic is under strong influence of
different air masses, and therefore heat
exchange between sea and atmosphere
shows a marked variability.
In the summer months heat input into
the sea is the strongest in June and July,
due to dominant short-wave solar
radiation. At that time the sea creates a
thermo cline, which is preserved until
The most common surface waves are
caused by Bora and Sirocco wind in
winter and the northwest wind (mistral)
Bora is a dry cold wind blowing direction
from north - northeast to east -
In summer, it usually lasts a day or even
several hours while in winter it can blow
up to two weeks.
Sirocco is a warm and moist wind which
blows from east - southeast to south -
southwest. Its consequences are high
waves and rain. In summer it usually
blows up to 3 days, and in winter it can
blow up to 3 weeks. Sirocco causes
significantly greater waves than Bora at
the same speed and duration. In coastal
areas waves appear significantly smaller
than at the open sea.
Mistral is a daily thermal breeze that
blows from the northwest. It blows in the
period from spring to autumn, in
daytime, frequently changing its
Burin blows in the opposite direction of
the Mistral. It blows strongest before
dawn and then abruptly stops. At night it
blows from the north - northeast in
northern Adriatic and from the east -
southeast in southern Adriatic.
Wave height ranges between 0.5 and
1.5 m. Summer temperatures in July
range between 34 and 38 ° C.
High and low tides have relatively small
amplitudes in the Adriatic. In the
southern part of Adriatic sea the
difference is less than 40 cm and in the
northern part it reaches up to 1 m high.
Along the eastern (Croatian) Adriatic
coast, there is an incoming (NW) sea
current that transports salty Levantine
water into the Adriatic, while the western
(Italian) coast of the Adriatic takes
leakage of the less saline water from the
Adriatic. The average current speed is
about 0.5 knots, but it can reach speed
of up to 4 knots.
The average salinity in the Adriatic is
38.3 g per milliliter.
Values of surface salinity decrease from
the southern to the northern Adriatic. On
Murter, due to the proximity of Lake
Vrana, the salinity is somewhat lower.
