Wherever you live or happen to travel to, never complain about the heat and humidity again. In the city of Bandar Mahshahr (population of about 110,000 as of 2010), the air felt like a searing 154 degrees (67.8 Celsius) today, factoring in the humidity. Its actual air temperature was 109 degrees (42.8 Celsius) with an astonishing dew point temperature of 90 (32.2 Celsius).

(If you use NOAA’s calculator, that actually computes to a heat index of 159 degrees). Bandar Mahshahr sits adjacent to the Persian Gulf in southwest Iran where water temperatures are in the 90s. Such high temperatures lead to some of the most oppressive humidity levels in the world when winds blow off the water. MORE
