🇦🇷 Buenos Aires vs 🇮🇳 Kolkata

Humid subtropical — hot humid summers, mild winters, year-round rainfall

Buenos Aires has a humid subtropical climate — hot and sticky summers, mild winters, and moderate rainfall year-round. The Pampas winds can create dramatic temperature swings. The city is in the Southern Hemisphere, so seasons are opposite to North America/Europe.

Kolkata's tropical wet-and-dry climate is dominated by the Bay of Bengal monsoon, the Hooghly River corridor, and the vast deltaic floodplain of the Ganges. The city experiences extreme humidity from May through October, with the river and surrounding wetlands amplifying moisture levels, while winter months bring dry northwesterly winds and brief cool spells. The dense urban core generates a pronounced heat island effect, but the Hooghly riverfront, the East Kolkata Wetlands, and the Maidan parkland create significant cooling corridors that shape neighborhood-level weather.
