Did We Just Experience the Hottest Summer Ever?

Summertime is supposed to be hot, right? But, according to scientists at NOAA, no other June through August time frame on record was as hot as 2019 — for the Northern Hemisphere at least. And it wasn’t just one part of the globe feeling the heat. Around the world, August 2019 tied as the second-hottest August on record (140 years).

The average global temperature in August was 1.66°F above the 20th century average of 60.1°F, tying it with 2015 and 2017 as the second-hottest August in the 140-year record. The hottest August in NOAA’s recordbooks was in 2016. The five hottest Augusts on record have all occurred since 2014.

This follows up on what was the planet’s hottest July on record. In addition to the heat, precipitation has been more than plentiful, too, lately.


The period of June through August, which also marks the Southern Hemisphere’s winter, was the globe’s overall second hottest in the 140-year record at 1.67°F above the 20th century average, behind June through August 2016.

June-Aug. 2019 global temperature map

A portion of a report from the NOAA’s National Centers for Environmental Information points out the most notable warm surface temperature departures from average during June through August 2019 were across much of the high latitudes in the Northern Hemisphere, specifically across the North Pacific Ocean, the Bering Sea, western Alaska, northern Canada, Central Europe, and North-Central Russia. The temperature departures from average in these locations were at least +2.7°F or higher.
