Iranian city soars to record 129 degrees: Near hottest on Earth in modern measurements
A city in southwest Iran posted the country’s 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. Iran’s previous hottest temperature was 127.4.
Weather Underground’s 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.
The scorching temperature reading was brought about by a dome of heat centered over the Middle East.
The excessively hot air over Ahvaz, a city of 1.1 million people, felt even more stifling due to high humidity. As the temperature climbed into the high 120s, the dew point, a measure of humidity, peaked in the low 70s; a high level for the desert location (due to air flow from the Persian Gulf, to the south). The heat index — a measure of how hot it feels factoring in the humidity — exceeded 140 degrees. This combination of heat and humidity was so extreme that it was beyond levels the heat index was designed to compute.
