July world’s hottest month ever

Reading Time: 2 minutes

July was the world’s hottest month ever recorded, a US federal scientific and regulatory agency has reported.

The data shows that the combined land and ocean-surface temperature was 0.93C (1.68F) above the 20th Century average of 15.8C (60.4F).

It is the highest temperature since record-keeping began 142 years ago. The previous record, set in July 2016, was equalled in 2019 and 2020.

Experts believe this is due to the long-term impact of climate change.

In a statement, the National Oceanic and Atmospheric Administration (NOAA) said that July’s “unenviable distinction” was a cause for concern.

“In this case, first place is the worst place to be,” NOAA administrator Rick Spinrad said in a statement.

“This new record adds to the disturbing and disruptive path that climate change has set for the globe.”

The combined land and ocean-surface temperature was 0.01C higher than the 2016 record.

July 2021 by the numbers

  • Around the globe: the combined land and ocean-surface temperature was 1.67 degrees F (0.93 of a degree C) above the 20th-century average of 60.4 degrees F (15.8 degrees C), making it the hottest July since records began 142 years ago. It was 0.02 of a degree F (0.01 of a degree C) higher than the previous record set in July 2016, which was then tied in 2019 and 2020.
  • The Northern Hemisphere: the land-surface only temperature was the highest ever recorded for July, at an unprecedented 2.77 degrees F (1.54 degrees C) above average, surpassing the previous record set in 2012.
  • Regional records: Asia had its hottest July on record, besting the previous record set in 2010; Europe had its second-hottest July on record—tying with July 2010 and trailing behind July 2018; and North America, South America, Africa and Oceania all had a top-10 warmest July.
