FAQ-INFO ABOUT DIVING IN CROATIA

Primošten is a town in Croatia situated in the south, between the cities of Šibenik and Trogir, on the Adriatic coast. Set upon a little island linked by a bridge to the land with stone houses and narrow lanes in Mediterranean style, with many bays, islets and peninsulas, place with extraordinary sea. It is built on a hill and is dominated by the parish church of St. George. Primošten has around 3000 inhabitants. Economy is based on farming, growing of vines and olives, fishing and tourism. Primošten has a mild Mediterranean climate and is naturally sheltered from the winds.

Yes, non divers are welcome to come whit you. You can decide to take your friends or children with us on the dive, where they can swim around the island where we dive. We also take people on one small island with Austrohungarian lighthouse on it and we have a picnic there.

We truly to keep our diving groups up to maximum of 8 to 10 persons. We usually say we do not sell diving, we sell an experience and excursion. It is important to us that romantic part of diving does not disappear, after the dive you can try some local drinks or have some fruit. There is also much more safety in smaller groups.

We always like to take new divers on few shallower dives so we can meet each other and see how we dive. All our dives do not cross the limit depending on categories of divers winch dive with us. Maximum depth for recreational and sport divers is 40m on Croatia. We only dive deeper if our customers have technical diving category.

The Adriatic Sea has a very marked annual change of the surface temperature. The average annual temperature is 11°C. During the winter, the sea is the coldest and the surface temperature is about 9°C ot 12°C ; very seldom, it can drop below that too. In the spring, the sea becomes warmer, and the surface temperature rises to 18°C. In the summer the surface of the sea reaches a very high temperature, of up to 22 to 25°C, and in the southern Adriatic and Istria up to 27°C. In the Adriatic, thermo clines, i.e. parts of the water column of the same temperature, are very well distinguished. The thermo cline is most evident during the summer, and, in the winter, the isothermal process arises, i.e. equaling of the temperature throughout the water column. In the summer, we can notice the first thermo cline at the depth of 3 to 5 m, the next one is at about 12 m, and yet another one at 18 metes, while below 30 m the temperature is mostly constant throughout the year.

Depths in Primosten are on standard dives down to 60, 70 meters and on cliff dives down to more than 100. these are maximum depths but we dive of course down to depth for which our group is certified 20 m, 30m, 40 m. The shallowest part of our sea is in Istria, where the depth does not exceed 50 m. From Pula, the seabed mildly drops, making a long, narrow valley which extends from Zirje towards Italy which is called Jabucka kotlina. The biggest depth there is about 240 m. From Jabucka kotlina, the bottom rises to Palagruza reef where the biggest depth is 130 m. Towards the south, the bottom drops steeply towards the Juznojadranska dolina, where the biggest measured depth is about 1,300 m.

The appearance of the underwater relief is the consequence of tectonic movements, abrasion or erosion which were active several million years ago, in times when certain parts of the seabed were land or the coastal area. Uneven areas on the bottom are constantly reduced by sedimentation of detritus from the land. That process is slow, but constant. Rogoznica in most parts has cliffs and stone bottoms. On lots of places you will see fields of Posidonia.

In the Adriatic, the high and low tides have relatively small amplitudes. In the southern part, the difference is rarely above some forty centimeters, while in the northern part it is somewhat bigger, so that it comes to 1 meter in Istria and the Gulf of Trieste. In some narrow channels and bays, the high tide can grow considerably during a strong sirocco. That phenomenon is characteristic for big and deep bays of the southern Adriatic. The tides are of a mixed type, which means that their rhythm is semidiurnal during the new and full moon, and of a daily type during the first and the last quarter. Their amplitudes are very irregular.

Sea currents occur under the influence of winds, the difference in pressure, temperature, and the differences in salinity. With respect to the direction, they can be horizontal or vertical. There are also bottom currents which appear as the consequence of moving of water from warmer areas to colder ones, during which the surface layer gets cold and descends towards the seabed. Currents are weakly observable in the Adriatic.The speed of currents changes in particular areas, but it also depends on time periods. The average speed of currents is about 0.5 knots, but they can also reach the speed of 4 knots.

The total quantity of salt dissolved in one kilogram of sea water is called salinity, which is usually expressed in grams and as the permillage. The salinity of the Adriatic Sea is 38.30 per mill averagely, i.e. there is 38.30 g of salt dissolved in 1 kg of water. In the northern part, the salinity is somewhat lower than in the middle and southern part because of the influence of the Po River.

Waves occur primarily as the consequence of the blowing of winds. The bigger the reach, i.e. the surface across which the wind blows, the higher the waves will be. Their strength depends on the configuration and the exposure of the coast. In that way, mixing of the surface layer with water from the deep is enabled, and the interaction between the atmosphere and the sea. We distinguish the crest and the trough of a wave. The length of the wave is the distance between two troughs. Most often, heights of waves in the Adriatic are between 0.5 and 1.5 metres, and they very rarely exceed 5 metres.

In Northern Adriatic visibility is not as clear as in mid or south Adriatic because of influence of the river Po. In Mid and South Adriatic visibilities is excellent sometimes more than 50 meters.
