🇬🇷 Athens vs 🇮🇹 Milan

Mediterranean — very hot dry summers, mild wet winters

Athens has a classic Mediterranean climate but is notably hotter and drier than coastal Greek islands due to its inland location in the Attica basin surrounded by mountains. Summers are among the hottest in Europe; winters are mild and pleasant.

Milan sits in the western Po Valley, one of Europe's most fog-prone and humidity-trapping basins, hemmed in by the Alps to the north and the Apennines to the south. The city experiences hot, humid summers with weak ventilation and cold, damp winters where temperature inversions trap pollution and moisture at ground level. The Navigli canal system and proximity to several pre-Alpine lakes introduce subtle moisture gradients, while the dense urban core generates one of Italy's strongest urban heat island effects.
