Europe faces another record-setting Heatwave this week

23 July 2019 | Adaptation

Europe's temperatures are in the rising once again for potential heatwave records. Paris and London could set new high-temperature records this week while the forests of Spain and Portugal are once again at risk of fires. 

Last month was the hottest June on record, riding on the back of a heat wave that saw France set an all-time high-temperature record as well as June records for the Czech Republic, Slovakia, Austria, Andorra, Luxembourg, Poland, and Germany. While the heat wave arriving this week isn’t forecast to be quite as fierce, it still has record-setting potential for major cities in Europe and could ensure July goes down as the hottest month the world has ever recorded.

The July heat wave will be caused by a near-identical pattern to the one that drove June’s extreme heat. Low pressure will stall over the North Atlantic, funneling the jet stream into a big swing over the UK and northern Europe. That will cut the region off from cooler Arctic air while allowing hot, dry air from the south to come rushing over the continent. The result will be temperatures rising over the course of the week and spiking on Wednesday and Thursday anywhere from 10-15 degrees Celsius (18-27 degrees Fahrenheit) above normal.

France, Spain, and Portugal—all of which were broiled by the last heat wave—are likely to see the mercury rise past 40 degrees Celsius (104 degrees Fahrenheit). That includes Paris, where the all-time high-temperature record of 40.4 degrees Celsius (104.7 degrees Fahrenheit) was set in 1947, according to AFP.

“Thursday (July 25) will be a potentially historically hot day,” François Jobard, a forecaster at Météo France, told the news agency. “We are forecasting 41 or 42 degrees in Paris on Thursday, and there is the strong chance of beating the record.”

Wildfires like those that took place in the region in June are also a growing concern, and large fires are already happening in Portugal. It could also bake in drought conditions in France, Germany, and other parts of Europe. But the heat wave will also extend to areas not enveloped by the June scorcher. That includes portions of Scandinavia and parts of the UK where all-time temperature records could also fall.

“The UK will experience another pulse of high temperatures this week, with the possibility of records being broken for not only July but also all-time records,” UK Met Office chief meteorologist Paul Gundersen said in a post by the forecast office.

The UK Met Office is forecasting temperatures of 37 degrees Celsius in southeast England. The current July record for London is is 36.7 degrees Celsius (98 degrees Fahrenheit), a record set at Heathrow Airport in 2015. The all-time UK temperature record is 38.5 degrees Celsius (101.3 degrees Fahrenheit). That was set in Faversham—located about 50 miles southeast of London—in August 2003 during the most deadly heat wave in modern European history.

A snap analysis found that climate change made the June heat wave “that intense is occurring at least 10 times more frequently today than a century ago.” While we’ll have to wait for this heat wave to play out before climate scientists have data to analyze, it seems safe to say climate change has almost certainly impacted it in some way. To wit, here’s that analysis again: “Every heatwave  occurring in Europe today is made more likely and more intense by human-induced climate change.”
