🇪🇬 Cairo vs 🇮🇳 Chennai

Hot desert — very hot dry summers, mild winters, virtually no rainfall

Cairo is one of the world's largest cities in one of the world's driest climates. Rain is essentially absent. Summers are brutally hot and dusty; winters are mild and perfect for sightseeing. The khamsin (hot desert wind) brings sandstorms in spring.

Chennai's tropical wet-and-dry climate is defined by its long Bay of Bengal coastline, which delivers the northeast monsoon from October to December — the city's primary rainy season, unusual for an Indian metro. The flat coastal plain offers little topographic relief, so microclimates are driven primarily by proximity to the sea, river corridors along the Adyar and Cooum, and dramatic variation in building density and green cover. Summer temperatures routinely exceed 40°C inland while coastal neighborhoods benefit from steady onshore sea breezes that moderate heat by 3–5°C.
