Ahvaz, Iran Temperature May Have Been Hottest In Modern Instrumental Record - Revised 129.2F
A city in southwest Iran posted the countrys hottest temperature ever recorded Thursday afternoon, and may have tied the world record for the most extreme high temperature. Etienne Kapikian, a forecaster at French meteorological agency MeteoFrance, posted to Twitter that the city of Ahvaz soared to 53.7°C (128.7 degrees Fahrenheit). Kapikian said the temperature is a new absolute national record of reliable Iranian heat and that it was the hottest temperature ever recorded in June over mainland Asia. Irans previous hottest temperature was 127.4.
Weather Undergrounds website indicates the temperature in Ahvaz climbed even higher, hitting 129.2 degrees at both 4:51 and 5 p.m. local time. If that 129.2 degrees reading is accurate, it would arguably tie the hottest temperature ever measured on Earth in modern times.
Christopher Burt, a weather historian for Weather Underground, has exhaustively analyzed world temperature extremes and determined the 129.2 degree readings posted in Mitribah, Kuwait on July 21, 2016, and Death Valley, Calif., on June 30, 2013, are the hottest credible temperature measurements that exist in modern records.
Officially, Death Valley set the record for the hottest temperature ever recorded on Earth on July 10, 1913, soaring to 134 degrees (57 Celsius). But Burt posted a devastating critique of that measurement in October 2016, concluding it was essentially not possible from a meteorological perspective, and that the weather observer committed errors. For the 129.2 degree-reading Ahvaz posted on Weather Underground to stand and match the highest modern global temperature, it will require review by the World Meteorological Organization.
