🇮🇳 Kolkata vs 🇬🇧 London

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.

Temperate oceanic — mild, cloudy, and notoriously changeable year-round

London's weather is famously mild but grey. It rarely gets very hot or very cold, but expect cloud cover most of the year. Summer (June–August) brings the best sunshine and warmth. Rain falls year-round but rarely in heavy bursts.
