Bottom line: As they say, “it’s not the heat, it’s the humidity.” And Bandar-e Mahshahr has it in spades.
This region of southern Iran is close to the Persian Gulf and has not only high temperatures, but also high levels of precipitation. Additionally, the city is surrounded by marshlands, which make the temperature even higher.
On July 31, 2015, the city’s heat index (that is, what the temperature feels like to the human body) was measured at a whopping 165 degrees Fahrenheit. It is the second-highest heat index ever recorded.
Note: All temperatures are in Fahrenheit.
