🇵🇰 Karachi vs 🇧🇷 São Paulo

Karachi's climate is dominated by its position on the Arabian Sea coast along the southern edge of the Sindh plain, creating a hot semi-arid environment moderated by maritime influence. The city experiences extreme heat from April to June before the southwest monsoon brings humid relief, while sea breezes penetrate unevenly across the sprawling metropolitan area depending on distance from the coast and building density. The Lyari and Malir river corridors, mangrove-fringed coastline, and stark contrasts between dense old-city fabric and open peripheral development create significant microclimate variation across the megacity.

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.
