And, June of this year had already set a sizzling record for that month over the past 140 years.
Furthermore, because July is usually the warmest month globally, this means that July 2019 wasn't only the hottest July ever recorded, but also the hottest month in general, ever recorded. Eek.
The period from January through July produced a global temperature that was 1.71 degrees F above the 20th-century average of 56.9 degrees, tying with 2017 as the second-hottest year to date on record. It hit 100 degrees in London and 109 in Paris - the highest temperature ever recorded there.
NOAA says Arctic sea ice this year sat at 19.8 percent below average, bringing it lower than the previous historically-slim levels recorded in July 2012.
The temperature records go back to 1880.
But a federal climate assessment released by the NOAA in November found that climate change "is affecting the natural environment, agriculture, energy production and use, land and water resources, transportation, and human health and welfare across the USA and its territories".
It is not a complete surprise that July 2019 surpassed previous records, as historic high-temperatures could be seen worldwide over the month. Last month was also the 415th consecutive month with temperatures above the 20th century average, it said.
Warm temperatures have drastically shrunk the extent of Arctic sea ice this year, putting it in a dead heat for title of lowest extent ever recorded.
Two weeks ago, the United Nations said this July "at least equaled if not surpassed the hottest month in recorded history".
Record-temperatures were present across parts of North America, southern Asia, the southern half of Africa, the northern Indian Ocean, the Atlantic Ocean, as well as across the western and northern parts of the Pacific Ocean.
According to Deke Arndt, the head of climate monitoring at NOAA, there's a 100 per cent chance that 2019 winds up being a top-5 warmest year, and it will most likely be the 2nd, 3rd or 4th warmest year, depending how temperatures rank between August and December.
