Weather forecasters in Europe warned on Tuesday, May 26, of extreme temperatures as a severe heat wave, caused by a phenomenon known as a "heat dome," is pushing temperatures well above normal seasonal levels across the continent.
This situation comes after a record Monday, where France recorded the hottest day of May since meteorological measurements began, while the United Kingdom also recorded unprecedented temperatures.
This phenomenon occurs when very warm air masses from North Africa are blocked by a high-pressure system over Western Europe. As a result, temperatures rise sharply, reaching levels usually only seen in the height of summer.
Restrictions on outdoor activities have been imposed in some regions of Italy, while beaches in southwestern France have filled up earlier than usual. Farmers also report that temperatures above 30°C have accelerated agricultural harvests.
Scientists point out that climate change caused by human activity is making these phenomena increasingly frequent and intense. Europe is warming faster than the global average, while heat waves are lasting longer and becoming more extreme.
In Spain, temperatures are expected to reach up to 38°C during the week, while in Italy some regions have restricted outdoor work during the hottest hours of the day.
In the United Kingdom, the Met Office weather service announced that Monday was the hottest day ever recorded in May, with 34.8°C in Kew Gardens, southwest London, 2 degrees higher than the previous record.
"This heat would be exceptional for Britain even in mid-summer, let alone in May," the Met Office said on the X network.
Experts warn that global warming is increasing the intensity of extreme phenomena such as heat waves, droughts and floods, causing temperature records to be broken more frequently.
Meteorologist Greg Dewhurst from the Met Office told AFP that the increase in extreme temperatures is "a clear indicator of climate change in action" and that such situations could become the "new normal".
Last week, British climate advisers warned the government that the country was "built for a climate that no longer exists" and called for infrastructure, including schools and hospitals, to be adapted to the new climate reality.
In 2022, temperatures in Britain exceeded 40°C for the first time since official records began.
Ireland also recorded record temperatures for May, with 28.8°C in Killarney and Clonmel.
A fire broke out in Edinburgh, Scotland, blanketing the city in smoke as temperatures reached 25°C.
In France, the meteorological agency said Monday was the hottest day ever recorded in May for the entire country. Temperatures are expected to remain between 33°C and 36°C in some regions and the heatwave could last until the end of the week.
In Paris, the temperature rose above 30°C for the first time this year, reaching 31.9°C on Saturday.
In Spain, the State Meteorological Agency (Aemet) warned that temperatures "exceptionally high for this time of year" will continue throughout the week, except in the Canary Islands.
"Tropical nights" are also expected in southwest Spain from Wednesday, where temperatures will not drop significantly even at night. The peak of the heat is expected from Wednesday to Friday, with temperatures from 36°C to 38°C.
Meanwhile in Italy, the Lazio region has adopted rules restricting outdoor work between 12:30 and 4:00 p.m., particularly for the agriculture, construction and logistics sectors. The measures will remain in force until September 15.
Similar restrictions were imposed last year, but only came into effect after May 30th.
