Baffin Bay less than deep near the coast, where the sea bottom is covered with gravel, crushed stone and sand. In the center, there is a deep pit called the Baffin Basin, reaching (see ), which is mostly covered in silt. Currents form a cyclonic circulation. On the eastern periphery, in summer, the West Greenland Current transports water from the Atlantic Ocean to the North. In its western part, the Baffin Island Current brings the Arctic waters to the south. The climate is Arctic with frequent storms, especially in winter. Average January temperatures are in the south and on the north. In

The Baffin Bay has three branches, which are named as follows (counterclockwise on the map above): Alazan Bay on the north (green), Cayo del Grullo (purple) and Laguna Salada (blue). Several ephemeral streams, including San Fernando, Santa Gertrudis and Los Olmos, flow into the bay, but only when it rains. Because of the scarce freshwater inflow and extensive evaporation, which is promoted by shallow water and warm climate, the bay has a relatively high water salinity reaching 75‰ (parts per thousand) in its northern part.
