🇮🇳 Kolkata vs 🇦🇺 Sydney

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 subtropical — warm summers, mild winters, year-round sunshine

Sydney enjoys one of the world's best climates. Summers are warm with beach weather; winters are mild enough for outdoor activities. The city is split between coastal suburbs (cooled by sea breezes) and inland western suburbs (dramatically hotter in summer).
