What is the Highest Temperature Ever Recorded?

The highest reliably recorded surface temperature in the world was in Death
Valley at 134 F (57 C).

The highest temperature ever recorded was 134 degrees Fahrenheit (57
Celsius) in Death Valley on July 10, 1913. Located in the US and stretching
across parts of California and Nevada, Death Valley is one of the hottest
desert areas in North America and has average temperatures over 100 degrees
Fahrenheit (38 Celsius). During the period of July 9 through July 13 in
1913, Death Valley’s temperatures were especially hot and reached at
least 129 degrees Fahrenheit (54 Celsius) each day, with July 10 reaching
the record-breaking 134 degrees Fahrenheit (57 Celsius). Death Valley is
prone to extreme heat because its lack of plant cover makes the desert
surface unprotected from sunlight, and the heat becomes trapped due to the
valley’s depth.
