🇦🇷 Buenos Aires vs 🇵🇰 Karachi

Humid subtropical — hot humid summers, mild winters, year-round rainfall

Buenos Aires has a humid subtropical climate — hot and sticky summers, mild winters, and moderate rainfall year-round. The Pampas winds can create dramatic temperature swings. The city is in the Southern Hemisphere, so seasons are opposite to North America/Europe.

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.
