That's how hot it will be in areas where at least 101 million people live, according to an AFP analysis. That includes more than 50 million people in France and 18 million in Germany.
In France, red warnings for extreme heat have been issued for large parts of the country. Wednesday was the hottest day recorded in the country since 1947, when temperatures reached just over 40 degrees in many cities in the south.
For more than 380 million Europeans, it will be at least 30 degrees Celsius on Thursday.
In Spain, at least 212 deaths that occurred between Sunday and Wednesday are linked to the heat wave.
