The main purpose of this ongoing blog is to track planetary extreme, or record temperatures related to climate change. Any reports I see of ETs will be listed below the main topic of the day. I’ll refer to extreme or record temperatures as ETs (not extraterrestrials).😉
Main Topic: Details on Latest Blazing Middle East Heatwave
Dear Diary. The Middle East is mainly a hot, arid portion of the world, but heat experience there has been ridiculous. All summer long portions of the Middle East have had spurts of record breaking, nearly intolerable heat. This week is no exception. A strong heat dome recently set up over the Arabian Peninsula and will mill around that area into next weekend:
An extension of that heat dome can found westward through North Africa all the way into Morocco. Which will persist well into next week as shown on the above two charts.
Up and coming meteorologist Colin McCarthy noted the following record near the Persian Gulf in Iran:
As stated, this heatwave has been occurring throughout the summer. Here is a Washington Post article from July describing eye opening heat from the Middle East:

The heat and humidity in the Persian Gulf region have soared to nearly intolerable levels this week, and there’s little relief in sight.
Some locations have seen the heat index, or how it feels when factoring in the humidity, reach 140 to 150 degrees Fahrenheit (60 to 65 Celsius), fueled by an intense heat dome, the warmest water temperatures in the world and the influence of human-caused climate change.
Temperatures at the Persian Gulf International Airport in Asaluyeh, Iran, climbed to 108 (42 C) on Wednesday and 106 (41 C) on Thursday, with both days recording a peak heat index of 149 (65 C). In Dubai, the temperature topped out at 113 (45 C) on Tuesday and the heat index soared to 144 (62 C). Other extreme heat indexes in recent days include 141 (61 C) in Abu Dhabi and 136 (58 C) at Khasab Air Base in Oman.
Last August, this same region experienced even more extreme heat indexes, climbing as high as 158 degrees (70 C).
The maximum air temperatures this week — generally between 105 and 115 (41 and 46 C) — have only been somewhat above normal. But the dew points — which are a measure of humidity — have been excessive, climbing well into the 80s (27 to 32 C). In the United States, any dew point over 70 degrees (21 C) is considered uncomfortably humid.
It’s the very high dew points that have propelled heat indexes up to 30 degrees (16 C) above actual air temperatures.
The extreme humidity levels are tied to bathtub-like water temperatures in the Persian Gulf, the warmest in the world. According to National Oceanic and Atmospheric Administration data, sea surface temperatures are as warm as 95 degrees (35 C).
Largely because of the high humidity, nighttime minimum temperatures have also remained exceptionally warm, in many cases staying above 85 (29 C).Temperatures in Iranshar, Iran, only dropped to 97 (36 C) on Wednesday night, its hottest July night on record.
A Washington Post analysis found that the wet-bulb globe temperature, which measures the amount of heat stress on the human body, reached 96 (36 C) at the Persian Gulf International Airport and 95 (35 C) in Dubai, exceeding the threshold of 89.6 (32 C) that researchers have said poses a risk to human survival if such heat is prolonged. The wet-bulb globe temperature, which was calculated using data from nearby weather stations, takes into account a combination of temperature, humidity, wind and clouds.
Researchers have identified the Persian Gulf among the regions most likely to regularly exceed life-threatening heat thresholds during the next 30 to 50 years. Dubai was recently ranked as the city having the most dangerous summer heat in the world, with dangerous heat on 89 percent of summer days. Doha, Qatar, came in second.

There were also numerous heat records in the same region last week, according to weather historian Maximiliano Herrera. The United Arab Emirates saw a scorching high temperature of 123 while Adrar, Algeria, tied its record of 122 (50 C). Cities in both Kuwait and Iraq reached 126 (52 C), and Al Ahsa, Saudi Arabia, notched a record of 124 (51 C). The city of Amarah recorded Iraq’s warmest nighttime low on record at 102 (39 C).
The same heat dome that’s in the Persian Gulf region has spread record heat northward into Eastern Europe, westward into northern Africa, and eastward into India, Pakistan and Indonesia. In Eastern Europe, high temperatures surpassed 104 (40 C), with some locations staying above 85 degrees (29 C) at night.
It was so hot in Greece on Wednesday that officials closed the Acropolis for five hours, according to the Associated Press.
The intense July heat comes after the temperature reached 125 (52 C) in Saudi Arabia in June, leading to hundreds of deaths from heatstroke during the Hajj pilgrimage. Also in June, nighttime temperatures remained as high as 95 (35 C) in Delhi on June 18.
Dangerous, record-setting heat swept across five continents in June, which was Earth’s hottest June on record according to NOAA. Scientists say the heat waves show how human-caused climate change has made life-threatening temperatures more common.
