An unseasonably intense heatwave has gripped Western Europe, with France, Spain, and the United Kingdom all experiencing record-breaking temperatures in May. In France, more than 350 towns, particularly in western areas, have registered their highest May temperatures ever recorded. The region of Landes in the southwest saw the mercury soar to 37.1°C, marking one of the most extreme spikes.
Across the Channel in the United Kingdom, the heatwave set a new national record for May, with temperatures hitting 34.8°C at Kew Gardens in London. This heatwave has seen temperatures in various European locales running 12°C to 13°C above the usual seasonal averages. Forecasters predict that this scorching weather will persist for several more days, with parts of Spain potentially reaching highs of 40°C as the week progresses.
French meteorological authorities attribute the sweltering conditions to a “heat dome” phenomenon. This occurs when hot air originating from Morocco is trapped under a robust high-pressure system. Officials have highlighted that such occurrences are becoming more frequent and severe due to climate change. In response to the rising temperatures, thirty-one French departments have been issued high-temperature alerts, with some areas placed under the second-highest warning level. This is the first instance of France’s national heat warning system being activated in May since its inception in 2004.
Amid these extreme conditions, temperatures in several French towns surpassed 35°C, and the capital, Paris, neared 33°C. Tragically, a participant in a 10-kilometre race near Paris suffered a fatal heart attack, attributed to the oppressive heat, with several others ending up in critical condition in hospitals. Meanwhile, southern Spain has already experienced temperatures reaching 38°C, and meteorologists caution that many areas could endure “tropical nights,” where temperatures remain above 20°C even after nightfall.
Experts have noted a troubling trend: heatwaves in Europe are occurring earlier in the year and are becoming increasingly common due to the ongoing impacts of climate change. This early onset of extreme heat raises concerns about the long-term implications for the region’s climate and the need for adaptive measures to protect populations from future weather extremes.
