🇮🇳 Kolkata vs 🇧🇷 São Paulo

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.

Subtropical highland — warm and humid with no distinct dry season

São Paulo sits at 2,500 feet (760m) elevation, making it cooler than its tropical latitude would suggest. The city receives substantial year-round rainfall. Winters (June–August) are the dry season with mild, clear weather. Summers bring intense afternoon thunderstorms.
