Europe Heatwave: Heat Dome Triggers Record Temperatures and Fatalities
Europe is experiencing a severe heatwave, the second major one in two months, since mid-June. Record temperatures have been recorded across the continent, leading to heat-related deaths and disruptions in daily life.
A code red heat alert, the highest level, has been issued in parts of the United Kingdom, France, Spain, and Italy. Code orange and other warnings are in effect in Germany, Switzerland, Luxembourg, Portugal, Belgium, the Netherlands, Poland, Hungary, Croatia, Bosnia and Herzegovina, Serbia, and Greece.
Countries have implemented emergency safety measures, including workplace restrictions, school closures, and reduced hours. France has kept public parks open around the clock and allowed swimming in canals and fountains. In the UK, water-spraying mist cannons and temporary splash pads have been set up. Tourist sites like the Louvre and Eiffel Tower have reduced hours, and some cinemas in Switzerland have opened air-conditioned spaces for public relaxation.
Over 60 heatwave-related deaths have been reported. In France, about 40 people, mostly young, drowned since June 18, as per Prime Minister Sebastien Lecornu. Three senior citizens died near Bordeaux, and two children died in a hot car. In Spain, a 90-year-old woman and a 68-year-old man died of heatstroke. Several others have been hospitalised.
The heatwave has caused power outages: a transformer failure in France left 68,000 households without electricity. Wildfire risks and potential drought conditions are also concerns. Alcohol consumption was restricted at events in red-alert areas. The Paris Fashion Week schedule was altered, outdoor events in the Netherlands were cancelled or modified, and Florence's Uffizi Galleries temporarily halted ticket sales due to air-conditioning failure.
According to Météo-France, Tuesday and Wednesday were France's hottest days since 1947, with a national thermal indicator average of about 29.9°C. Temperatures reached 43-44°C in France and Spain, above 36°C in the UK, 39-41°C in Italy, and 35-38°C in Germany, Belgium, and the Netherlands. Spain's AEMET recorded its highest daily average June temperatures since 1950 on Monday (28.08°C) and Tuesday (28.17°C).
The phenomenon is attributed to a 'heat dome' – a strong high-pressure system that traps hot air in the upper atmosphere, acting like a lid. This is driven by an 'omega block,' a stuck wind pattern that prevents ventilation, keeping temperatures high even at night. While heat domes occur naturally, climate change may increase their frequency and intensity.
