Water temperatures in the Persian Gulf routinely warm into the 90s

southwest Iran reported a temperature of 109 F (43 C) and a dewpoint of
90 F (32 C). Using the American heat index formula, those figures

was even hotter on Friday at the Mahshahr Airport when temperatures
reached 114.8 F at 4:30 pm local time with a dew point of 89.6 F,
leading to a heat index value of an incredible 164 F (73 C).
