Where summer routinely crosses 50°C
10 Hottest Cities in the World
Gulf capitals, Saharan trade towns and a Pakistani city that has hit 53°C — these are the urban places where heat is the defining weather story of the year.
Cities don't get hot by accident. The hottest are stranded inland behind mountains, parked over the Sahara or the Arabian Peninsula, or sealed under summer high-pressure domes that bake the streets for weeks at a time. The records keep climbing.

Marble Bar holds the record for the longest streak of 100°F+ days anywhere on Earth — 160 in a row, set in the Pilbara in 1923–24.
