For the Romanian seaside, whose length does not exceed 245 km, in the North are the specific low banks, but to the South, there are the high cliffs of 35-40 m. At the base of those cliffs, a sandy and very sunny beach stretches.

This lake is well known for its miraculous, healing qualities of the sapropel mud and the salty water. The lake is former sea golf with sand bar, preventing water to enter, and because of the evaporation over the centuries, the water there is 8 times saltier than sea water.

General Information on Climate:
The temperature ranges from temperate to moderate continental, with Pontic influences. The average annual temperature is 11.3 °C (0 °C in January and 22 °C in July).

Climate Characteristics Specific to the Area of Eforie:
Winter Temperatures: from 4°C to 8°C, the lowest registered temperature;
Summer Temperatures: from 25°C to 35°C;
It should be noted that Eforie is slightly away from Constanţa and it is composed by Eforie Nord and Eforie Sud, these two being separated by 5 km.
The climatic conditions are more favorable to Eforie Sud than to Eforie Nord, because Eforie Sud benefits from a Mediterranean microclimate, which brings a difference of + 4 °C in comparison to Eforie Nord.
Moreover, Eforie Nord has more gloomy conditions, for instance, in winter, when Eforie Sud has a blue, clear sky and is sunny, at Eforie Nord may even rain , and/or  with fog, and/ or sky sailing.
This is due to a land tongue exposed to a climatic stress that juxtaposes the lake and the sea, between the two geographical zones; this land tongue favorites Eforie Sud, in detriment of Eforie Nord.
