🇹🇷 Istanbul vs 🇵🇰 Karachi

Mediterranean-influenced humid subtropical — warm summers, cool wet winters

Istanbul straddles two continents with a climate to match. The Bosphorus creates a persistent wind corridor that moderates summer heat. Winters are cold and rainy with occasional snow. Spring and fall are exceptional.

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.
