🇮🇳 Chennai vs 🇳🇴 Oslo

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.

Humid continental — cold snowy winters, warm short summers, sheltered fjord location

Oslo benefits from its position at the head of the Oslofjord, which moderates temperatures compared to Norway's exposed coastline. Summers are genuinely warm and long-daylit; winters are cold and snowy with some of Scandinavia's best skiing on the doorstep.
