But just nine years later, on September 13, 1922, a weather station in El Azizia, Libya, recorded a temperature of 58.0Â°C (136.4Â°F). According to the World Meteorological Organization (WMO), that remains the highest air temperature ever measured.
These come from 1800 weather stations scattered across all the continents, ranging from the Antarctic to the northern tip of North America.
