Europe Braces for Sweltering July

Temperatures are sizzling across Europe this week amid an intense and prolonged period of heat. And it’s only just begun. Italy, Spain, France, Germany and Poland are all facing a major heatwave with air temperatures expected to climb to 48C on the islands of Sicily and Sardinia — potentially the hottest temperatures ever recorded in Europe. An anticyclone — a high-pressure area — named Cerberus (named after the monster from Dante’s Inferno) coming from the south will cause temperatures to rise above 40C across much of Italy. This comes after a spring and early summer full of storms and floods.

The highest temperature in European history was broken on 11 August 2021, when a temperature of 48.8C was recorded in Floridia, an Italian town in the Sicilian province of Syracuse. That record may be broken again in the coming days. The animation below uses data from the Copernicus Sentinel-3 mission’s radiometer instrument and shows the land surface temperature across Italy between 9 and 10 July. As the image clearly shows, in some cities the surface of the land exceeded 45C, including Rome, Naples, Taranto and Foggia. Along the east slopes of Mount Etna in Sicily, many temperatures were recorded as over 50C.
