The City of Light became the city of heat on Thursday, as Paris recorded its highest-ever temperature thanks to a sizzling heat wave that’s been blasting Europe.

The mercury in the French capital skyrocketed to 108.7 degrees by Thursday afternoon, smashing the previous record of 104.7 degrees set in July 1947, meteorologists said.

The ferocious heat proved treacherous for locals, whose rail commutes were crippled by the rising temps.

“It’s so hot in the metro, it’s unbearable. There are so many people, no air conditioning and everyone is on top of each other,” said Paris commuter Petra Ulm, 34, according to the AFP.

The Netherlands, Belgium and Germany also reached new record heats, with Britain forecast to also see record-high temps.

A scorching 104.7 degrees was reported Thursday in the southern Netherlands municipality of Gilze en Rijen. That temperature surpassed the 102.7 degrees recorded a day earlier in the southern Netherlands city of Eindhoven.

In Belgium, the temperature rose to a new high of 105 degrees Thursday.

“This is the highest recorded temperature for Belgium in history since the beginning of the measurements in 1833,” said Alex Dewalque of the Royal Meteorological Institute of Belgium.

In Germany, a record high of 106.7 degrees was hit in the town of Lingen, officials said.

Temperatures in Britain were expected to climb past 102 degrees for the first time ever.

By Thursday afternoon in the UK, the maximum July temperature record was broken in Heathrow, London, as the mercury rose to 98 degrees, according to the Met Office.

In the UK, trains were ordered to run more slowly amid mass train cancellations in the area.

Thursday marked the third consecutive day of the second heat wave this summer to plague Europe.
