🇮🇳 Kolkata vs 🇪🇸 Madrid

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.

Hot semi-arid — very hot dry summers, cold winters, minimal rainfall

Madrid sits on the Castilian plateau at 2,100 feet (640m), giving it more extreme temperatures than coastal Spanish cities. Summers are scorching and dry (one of Europe's hottest capitals); winters are cold and crisp. Spring and fall are ideal.
