Highest temperature recorded on Earth - wikipedia Highest temperature recorded on Earth Furnace Creek Ranch, the location of the highest recording According to the World Meteorological Organization ( WMO ), the highest confirmed air temperature on Earth was 56.7 ° C ( 134.1 ° F ) in Furnace Creek Ranch, California, located in the Death Valley desert in the United States, on July 10, 1913. While measuring air temperature is standard, there are two other main ways that a temperature can be recorded. Contents 1 Measurements 1.1 Air and ground temperature 1.2 Satellite measurements 2 Unverified claims 3 See also 4 References Measurements Air and ground temperature The standard measuring conditions for temperature are in the air, 1.5 meters above the ground, and shielded from direct sunlight. From 1922 until 2012, the WMO record for the highest official temperature on Earth was 57.8 ° C ( 136.0 ° F ), registered on September 13, 1922 in ' Aziziya, Libya. In January 2012, the WMO decertified the 1922 record, citing persuasive evidence that it was a faulty reading recorded in error by an inexperienced observer. Christopher C. Burt, the weather historian writing for Weather Underground who shepherded the Libya reading 's 2012 disqualification, believes that the 1913 Death Valley reading is also `` a myth '', and is at least 4 to 5 ° F ( 2.2 to 2.8 ° C ) too high. This same conclusion has also been reached by historians Dr. Arnold Court and William Taylor Reid. If the 1913 record were to be decertified, the current highest recorded temperature on Earth would be 54.0 ° C ( 129.2 ° F ), recorded both in Death Valley on June 20, 2013, and in Mitribah, Kuwait on July 21, 2016. Temperatures measured directly on the ground may exceed air temperatures by 30 to 50 ° C. The theoretical maximum possible ground surface temperature has been estimated to be between 90 and 100 ° C ( between 194 and 212 ° F ) for dry, darkish soils of low thermal conductivity. While there is no highest confirmed ground temperature, a reading of 93.9 ° C ( 201 ° F ) was allegedly recorded in Furnace Creek Ranch on July 15, 1972. Satellite measurements Temperature measurements via satellite also tend to capture occurrence of higher records but, due to complications involving satellite 's altitude loss ( a side effect of atmospheric friction ), these measurements are often considered less reliable than ground - positioned thermometers. The highest recorded temperature taken by a satellite is 66.8 ° C ( 152.2 ° F ), which was measured in the Flaming Mountains of China in 2008. Other satellite measurements of ground temperature taken between 2003 and 2009, taken with the MODIS infrared spectroradiometer on the Aqua satellite, found a maximum temperature of 70.7 ° C ( 159.3 ° F ), which was recorded in 2005 in the Lut Desert, Iran. The Lut Desert was also found to have the highest maximum temperature in 5 of the 7 years measured ( 2004, 2005, 2006, 2007 and 2009 ). These measurements reflect averages over a large region and so are lower than the maximum point surface temperature. Unverified claims The following are unverified claims of extreme heat over the current world record of 56.7 ° C ( 134.1 ° F ). Date Temperature ° C / ° F Type Cause Location Description July 11, 1909 57.8 ° C ( 136.0 ° F ) Air Heat burst Cherokee, Oklahoma ( United States ) This incident was recorded at 3 : 00AM ( CT ), and reportedly caused crops to desiccate in the area. July 6, 1949 70 ° C ( 158.0 ° F ) Air Heat burst Figueira da Foz and Coimbra ( Portugal ) Within two minutes, a heat burst reportedly drove the air temperature from 38 to 70 ° C ( 100.4 to 158.0 ° F ). 1960 60 ° C ( 140.0 ° F ) Air Heat burst Kopperl, Texas ( United States ) A heat burst is claimed to have sent the air temperature to near 140 ° F ( 60 ° C ), supposedly causing cotton crops to become desiccated and drying out vegetation. June 1967 86.7 ° C ( 188.1 ° F ) Unknown Heat burst Abadan ( Iran ) An alleged temperature of 86.7 ° C ( 188.1 ° F ) was recorded during a heat burst in Abadan, Iran.
