It is 41 km at its widest and 25 m at its deepest, reaching 31 km at its greatest innermost extent,^[1] approximately where the Bulgarian city and major port of Burgas is located. Other towns in the region include Pomorie, Sozopol and Nesebar. The Burgas Bay is the Black Sea's westernmost point.

The bay gets narrow to the west. While the northern coast is lower and has two big peninsulas, at Nesebar and Pomorie, the southern part of the bay is rougher, with many little inlets and headlands. The water's salinity in the bay is 17‰; the sand is of magnetite origin. The Burgas Lakes are located in the wetlands to the west.

There are several small islands in the southern part of Burgas Bay, most notably St. Ivan Island and St. Peter Island, St. Anastasia Island (the old Bolshevik), St. Thomas Island (popularly the Snake Island).
