🇹🇷 Istanbul vs 🇮🇳 Kolkata

Mediterranean-influenced humid subtropical — warm summers, cool wet winters

Istanbul straddles two continents with a climate to match. The Bosphorus creates a persistent wind corridor that moderates summer heat. Winters are cold and rainy with occasional snow. Spring and fall are exceptional.

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.
