Europe Suffers Hottest Summer on Record

Europe has just suffered its hottest summer on record, according to data compiled by The Copernicus Climate Change Service (C3S).

C3S is implemented by the European Centre for Medium-Range Weather Forecasts on behalf of the European Commission with funding from the EU, and routinely publishes monthly climate bulletins reporting on the changes observed in global surface air temperature, sea ice cover and hydrological variables. 

Extreme temperatures and dry conditions exacerbated air pollution and led to drought and wildfires across the contintent.

August 2022 surface air temperature:

Globally, the average August 2022 temperature was: 

  • 0.3°C higher than the 1991-2020 average for the month, joint third warmest August on record
  • similar to the values for August 2017 and 2021 and within about 0.1°C of the higher values reached in August 2016 and 2019

The average temperature over Europe in 2022 was: 

  • the highest on record for both August and summer (June – August) by substantial margins of 0.8°C over 2018 for August and 0.4°C over 2021 for summer 
  • European temperatures were most above average in the east of the continent in August, but were still well above average in the south-west, where they had been high also in June and July
  • Heatwaves were prevalent in this part of Europe and over central and eastern China for all three summer months. North America also experienced one of its warmest summers  

August 2022 – Hydrological conditions:

  • August 2022 was generally much drier than average in much of western and parts of eastern Europe.
  • Conversely, it was wetter-than average over most of Scandinavia and parts of southern and southeastern Europe. Southern regions were hit by a “derecho” storm, with extreme winds and rainfall.
  • Conditions were also wetter than average in many extratropical regions of North America and Asia: in many locations heavy precipitation triggered floods and inundations. Pakistan saw particularly severe conditions with record breaking rainfall.
  • Among the drier-than-average extratropical regions, parts of China experienced severe drought.

Boreal summer 2022 – Hydrological conditions:

  • The summer 2022 was characterized by hot and dry conditions over much of western Europe. In much of Scandinavia, regions of central and south-eastern Europe, Greece and western Turkey, conditions were predominantly wetter than average.
  • In boreal summer 2022, it was drier than average in central North and South America and across central Asia. The Horn of Africa continued to experience drought. Conditions were predominantly wetter-than-average in south Asia, particularly in Pakistan, in eastern Australia and in most of southern Africa.

Senior Scientist for the Copernicus Climate Change Service, Freja Vamborg, states: “An intense series of heatwaves across Europe paired with unusually dry conditions, have led to a summer of extremes with records in terms of temperature, drought and fire activity in many parts of Europe, affecting society and nature in various ways. The Copernicus Climate Change Service data shows that we’ve not only had record August temperatures for Europe but also for summer, with the previous summer record only being one year old.”
