This corresponds to a wet-bulb temperature of 34.6 °C (94.3 °F), slightly below the 35 °C (95 °F) mark that is considered the maximum humans can tolerate, above which extended exposure will lead to death.

This city was founded in the time of the Sassanids of Mahshur and in 231 AD during the reign of Ardashir Babakan under the name of Rivardshir, which was then called Reyshahr.

[4] In many travelogues and histories, the port of Mahshahr has been mentioned with names such as Mehroban, Machol, and Mahshur, for example, Ibn Battuta has called this port "Majul" (Arabicized Machol), which according to Soltani Behbahani, is the same as Mahshur (some sources: Ma'shur) which is derived from ushr (customs) (p. 227).

[3] Important Explanations about Mehroban: Some people mistakenly believe that the Mehrubani mentioned in the chronicles (including Nasir Khusrau's travelogue) is actually the place where its ruins are located near Hendijan today.

[15] As for Mahshahr itself, he says: "Machol (written in the book in Arabic as Majul) is a small town next to a creek that branches off from the Persian Sea.

[16] The port of Mahshur (Mahshahr) was not very important in the Safavid period and afterwards and its name is not mentioned in historical and geographical books.

[18] Kazerouni recorded the distance between it and the sea of one and a half leagues and wrote: "At high tide, the sea water comes to the mouth up to half a farsang of the mentioned port, and small and medium-sized ships come up to half a farsang of the said port and take out what is the cargo of the ships from them, and that place is called Sayf (harbor), and then from its castle, the number of houses (three hundred houses), its annual tribute He mentions 1,200 piasters and a head of butter that they gave to Shaykh Thamer Khan, women who wore clothes similar to Arab clothes, and men who wore clothes made up of Arabic and non-Arabic clothes."

[Pg 21] Among its historical monuments are the remains of dilapidated buildings called "Tal Kafaran", many cisterns and wells hewn stones, and the ruins of the settlement of Reyshahr near the northeast of Bandar Mahshahr.
