Western Europe is grappling with a significant early-summer heatwave, affecting countries like France, Spain, and the United Kingdom with unprecedented high temperatures for the month of May. In France, more than 350 towns have recorded their highest May temperatures ever, predominantly in western areas. The most extreme temperature noted was 37.1°C in the south-western region of Landes.
The United Kingdom has also set a new national record for May, with temperatures soaring to 34.8°C at Kew Gardens in London. Across several parts of Europe, temperatures are currently reported to be 12°C to 13°C above the seasonal norms. Meteorologists predict the heatwave will persist for several more days, with forecasts indicating that some regions in Spain might see the mercury climb to 40°C by the end of the week.
French meteorological authorities have attributed these extreme conditions to a phenomenon known as a heat dome. This occurs when hot air originating from Morocco becomes ensnared under a robust high-pressure system. Officials have cautioned that such extreme weather events are becoming more frequent and severe as a result of climate change. In response, thirty-one French departments have been placed on high-temperature alerts, including several under the second-highest warning level. Notably, this marks the first activation of France’s national heat warning system in May since its establishment in 2004.
In several French towns, temperatures have exceeded 35°C, with Paris nearing 33°C. The extreme heat has already had dire consequences, as authorities reported a fatality during a 10-kilometer race near Paris, where a participant is believed to have suffered a heart attack. Several other individuals were hospitalized and remain in critical condition. Meanwhile, in Spain, temperatures have already reached 38°C in the southern regions and are anticipated to climb further as the week progresses. Meteorologists have warned that many areas might experience “tropical nights,” where temperatures do not drop below 20°C even after nightfall.
Experts are increasingly concerned as heatwaves in Europe are occurring earlier in the year and with greater frequency, a trend attributed to the long-term effects of climate change.
