🇮🇳 Kolkata vs 🇨🇿 Prague

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.

Humid continental — cold winters, warm summers, year-round rainfall

Prague's central European climate brings cold winters, warm summers, and the most visited city center in Europe. The Vltava River valley traps cold air in winter and creates humidity in summer.
