Iranian City Soars To Record 129F Degrees: Near Hottest On Earth in Modern Measurements (washingtonpost.com)

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. From a report on The Washington Post: Etienne Kapikian, a forecaster at French meteorological agency MeteoFrance, posted to Twitter that the city of Ahvaz soared to "53.7C" (128.7 degrees Fahrenheit). Kapikian said the temperature is a "new absolute national record of reliable Iranian heat" (alternative, non-paywalled source) 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.
