The hottest temperature ever reliably measured in
a desert was 134 degrees F in Death Valley of the Mojave Desert on
July 10, 1913. An even hotter temperature measured in the Sahara
has been discounted by most scientists as it was improperly
measured by inexperienced technicians.
the north American desert is the hottest thats my answer hope this help you like it helped me.
The hottest desert in the World is not the North American Desert, it is in fact the Sahara Desert in Africa. Where the world's hottest temperature of 136 degrees F ( 57.8 C) was recorded.
