Varna Bay is situated in the northern part of the Black Sea Coast between cape Galata and cape St. George. Its maximum width is 3.5 nm. Varna Bay is the second largest after the Bay of Burgas in the Bulgarian Black Sea Coast. The beach line is covered with sand and the central part is covered with silty sediments. The bay has a flat bottom inclined eastwards. Its maximum depth is 18.5m. At the west part it is artificially connected to Varna Lake, thus having a great effect on the biodiversity in the two basins.

The city of Varna is located on the north and west coasts of Varna Bay and the northeast coast of Varna Lake. South of the channel connecting the bay and the lake are located the Asparuhovo and Galata districts. On the north coast are located the main industrial zone and the port complex. Northeast of them are located the central part of the city with the historical center (the so-called "Greek Quarter") and the central beach.

The climate of Varna is maritime , relatively mild in the warm part of the year. The average January temperature is 1.7 ° С, the average July temperature is 22.8 ° С, the average annual temperature is 12.2 ° С, the absolute minimum temperature is –24.3 ° С (measured on 10th Feb 1929), the absolute maximum temperature is 41.4 ° С in July. The average annual rainfall is 498 mm, the maximum is in June and November and minimum in February.

The longest sunshine in Varna is in July and August – 331 hours and 313 hours respectively. In the vicinities of the city the climate is suitable for cultivation of Mediterranian crops like pomegranate, paradise apple, kiwi, fig, laurel-leaves. The city of Varna is appropriate for balneotherapy as the climate is like a natural inhaler.

On the north of Varna is The Frangen Plateau (the maximum height 356m) which prevents in some extent from the strong north and northeast winds in the winter. Usually from May to October the temperatures are between 18 °C ÷ 31°C, and the average temperature in July and August is 22.8 °C. In the summer the sea water temperature is about 20°C, as in the hottest days the sand can be heated to 60°C.

The average height of the waves in Varna Bay is about 61cm.

Varna Lake is in Northeast part of Bulgaria, close to the city of Varna. It is connected with Varna Bay and Beloslav Lake artificially by channels. It is fed up through the Beloslav Lake mainly by Devnia springs.

After excavation works for a navigational channel the level decreases about 1.5m, and the water salinity increases to 8%. The marshy areas on the lake coasts are drained. In 1976 a new deeper and wider channel is done (excavated), resulting in increase in the water salinity to 15% on the surface and 17% at the bottom layers. In the deepest bottom areas there is a hydrogen sulfide silt used for mud treatment.

The vessels height is also limited because over the Channel 1 is crossing Asparuhov Bridge. All channels dues are collected by Bulgarian Ports Infrastructure Company (BPIC).
