Temperatures in the southwestern city of Ahvaz hit 53.7°C (128.7 degrees Fahrenheit) on Thursday, with another source citing 129.2 degrees F.
If confirmed, this would arguably tie for the hottest temperature ever measured on Earth in modern times, according to a report from The Independent.
The Iranian cabinet decided on Wednesday to authorise banks, state offices, city halls, public and non-governmental institutions in 9 provinces to change their working hours because of the summer heat, starting at 6:30 and finishing at 13:30.
The 9 provinces are Hormozgan, Khuzestan, Bushehr, and Sistan & Baluchestan, as well as a number of towns in Kerman, Fars, Yazd, Ilam and Semnan provinces.
