Composition & Healing Sea

The transparency and the absence of harmful substances have resulted in high quality of the sea around Lošinj.

From 2009 to 2012, all measuring points demonstrated “top quality” of the sea, which is a proof of a quality, clear, and preserved sea on Lošinj’s beaches, making us a perfect destination for swimming.

Measurement of sea water quality

In accordance with the European Directive on the management of bathing water quality (Directive 2006/7/EC of the European Parliament and the Council), the Institute for Public Health of the Primorje-Gorski kotar County conducts measurement of the sea water quality every 15 days through 10 sampling in the period from 15 May to 30 September. Measurements are performed at 31 points in the following order: Sunčana Bay at 6 points, 4 points in the area of Mali Lošinj, 6 in the area of Čikat, 5 points in Veli Lošinj, and 10 points from the Bučanje Bay near Sv. Jakov to the lighthouse in Osor.

On the basis of the Regulation on sea bathing water quality (OG 73/08), which prescribes limit values for microbiological parameters (intestinal enterococci and Escherichia coli), the objective is to assign a rating for the water quality for each measure individually, but also on an annual basis, for a period of 3 seasons and the current year. This rating ranges from excellent, good, satisfactory to unsatisfactory quality, and the results are published on the official website of the European Environmental Agency and the website of the Agency for Environmental Protection of the Ministry of Environment and Nature Protection of Croatia, and are comparable with the results for the Mediterranean and Europe.
