🇮🇳 Kolkata vs 🇵🇱 Warsaw

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, variable transitional seasons

Warsaw has a typical Eastern European continental climate. Winters are cold and grey; summers are warm and increasingly sunny. The city sits in the flat Polish Plain with no geographic barriers to arctic air masses in winter or Mediterranean warmth in summer.
