Africa holds many heat-related records: the continent has the hottest extended region year-round, the areas with the hottest summer climate, the highest sunshine duration, and more.
The Sahara Desert features a hot desert climate (Köppen climate classification BWh).The Sahara Desert is one of the driest and hottest regions of the world, with a mean temperature sometimes over 30 °C (86 °F) and the average high temperatures in summer are over 40 °C (104 °F) for months at a time, and can even soar to 47 °C (117 °F).
