Climate Overview
Chennai
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.
Seoul
Humid continental — hot humid summers, cold dry winters, beautiful spring and fall
Seoul has four distinct seasons. Cherry blossoms in April and autumn foliage in October rival Tokyo's. Summers bring the monsoon (jangma) and intense heat; winters are dry and bitterly cold with clear blue skies.
