Deadly Heat Wave Sweeps Western Europe, Breaking Records

Thursday, May 28, 2026

A record-breaking heat wave has swept across Western Europe, causing at least seven deaths in France and shattering multiple May temperature records in countries including the UK, Spain, Portugal, and Morocco. The extreme heat, driven by a persistent high-pressure system, highlights Europe's limited air conditioning infrastructure and raises concerns about the region's ability to cope with more frequent intense heat events in the future.

A severe heat wave has swept across Western Europe in recent days, shattering temperature records and contributing to multiple fatalities. Temperatures soared 15 to 20 degrees above average, placing significant strain on residents as they sought relief from the intense heat.

In France, authorities have reported at least seven deaths potentially linked to the extreme heat. The southwestern town of Hossegor recorded a temperature of 98.8 degrees Fahrenheit on Monday, marking the highest May temperature ever documented in the country. Among the fatalities, five people drowned, according to Maud Bregeon, a spokesperson for the French government, who noted that others died during sporting events taking place amid the heat.

The United Kingdom also experienced historic temperature peaks. Kew Gardens in London reached 94.6 degrees on Monday, eclipsing a previous May record of 91 degrees set in Regent’s Park in 1944. The following day, Kew Gardens recorded an even higher temperature of 95.2 degrees. In Wales, Hawarden Airport recorded 90 degrees on Monday, breaking a decades-old record dating back to World War II.

Southern Europe and parts of North Africa have not been spared. Daytime highs in Spain and Portugal neared 104 degrees Fahrenheit, while Morocco experienced its warmest May night on record, with temperatures holding steady at 84.7 degrees.

Meteorologists attribute the heat wave to a persistent ridge of high pressure over the Iberian Peninsula and Western Europe. This “heat dome” effect causes the air to warm and dry out substantially, leading to prolonged periods of elevated temperatures.

Europe’s limited adoption of air conditioning—present in only about 20 percent of homes—exacerbates vulnerability to the unusually warm overnight temperatures. The combination of sweltering days and hot nights poses significant health risks, particularly for vulnerable populations.

Officials have issued warnings about the dangerous conditions resulting from the heat wave, which includes stifling nighttime temperatures that impede recovery from daytime heat exposure. The extreme weather event underscores concerns about Europe’s preparedness for increasingly frequent and intense heat episodes.
