at velocities of . The Black Sea outflow moves westward along the northern Aegean Sea, then flows southwards along the east coast of Greece.
The physical oceanography of the Aegean Sea is controlled mainly by the regional climate, the fresh water discharge from major rivers draining southeastern Europe, and the seasonal variations in the Black Sea surface water outflow through the
Dardanelles Strait.
Analysis of the Aegean during 1991 and 1992 revealed three distinct water masses:
* Aegean Sea Surface Water – thick veneer, with summer temperatures of 21–26 °C and winter temperatures ranging from in the north to in the south.
* Aegean Sea Intermediate Water – Aegean Sea Intermediate Water extends from to with temperatures ranging from .
* Aegean Sea Bottom Water – occurring at depths below with a very uniform temperature () and salinity (3.91–3.92%).

, most of the Aegean is classified as Hot-summer Mediterranean (''Csa''), with hotter and drier summers along with milder and wetter winters. However, high temperatures during summers are generally not quite as high as those in arid or semiarid climates due to the presence of a large body of water. This is most predominant in the west and east coasts of the Aegean, and within the Aegean islands. In the north of the Aegean Sea, the climate is instead classified as
Cold semi-arid ''(BSk)'', which feature cooler summers than Hot-summer Mediterranean climates. The
Etesian winds are a dominant weather influence in the Aegean Basin.

Population
Numerous Greek and Turkish settlements are located along their mainland coast, as well as on towns on the Aegean islands. The largest cities are Athens and Thessaloniki in Greece and İzmir in Turkey. The most populated of the Aegean islands is Crete, followed by Euboea and Rhodes.

last ice age (about 18,000 years ago) sea levels everywhere were lower, and there were large well-watered coastal plains instead of much of the northern Aegean. When they were first occupied, the present-day islands including
