September 13, 1922. A temperature of 57.8° Celsius (136° Fahrenheit) is recorded in the shade in Al-Aziziyah, Libya. It is the highest shade temperature ever measured on Earth. There is some evidence that the equipment and the conditions for the reading may have given an elevated figure: the thermometer used was less sophisticated than most models present in weather stations at the time, while the reading may also have been influenced by the presence of black tarmac nearby. The second highest temperature on record is 56.7°C (134°F) in Death Valley, California in 1913. Third on the list is the 53.9°C (129°F) recorded in Tirat Tsvi, Israel in 1942.
