The World's Highest Temperature Was Measured in Death Valley in July - Apparently.
On July 10, 1913, a temperature of 134 degrees Fahrenheit (56.7 degrees Celsius) was recorded at Furnace Creek Ranch in Death Valley, California. This reading, which still stands as the highest ever recorded, was taken by a weather observer named E.A. Stevens using a thermometer at the time. This extreme heat was part of a prolonged heat wave that affected the region, and while the accuracy of the reading has been disputed, it remains the most extreme temperature ever officially recorded by the World Meteorological Organization.
