The sea breeze is stronger in summer. The natural cure factors are the water of the Black Sea, which is chlorided, sulphated, sodic, magnesian, hypotonic (mineralization 15.5g), the sulphurous, chlorided, bicarbonated, sodic, calcic, mesothermal (21-28 °C) mineral waters of the springs in the northern part of the city, in the area of the beach between Saturn and Venus, the sulphurous peat mud, rich in minerals, which is extracted from the peat bog north of the city (expected to last another 250 years) and the marine climate, rich in saline aerosols and solar radiation that have a bracing effect on the organism.
