Western Europe records hottest-ever June as heatwaves intensify, EU monitor says

Western Europe endured its hottest June ever, causing widespread sleep deprivation and fatal wildfires. Temperatures soared significantly above recent averages, impacting local and global climate patterns. Massive blazes erupted across France and Spain, overwhelming emergency services. The United Kingdom faces an extended heatwave and extreme marine conditions. These compounding disasters highlight the tangible effects of ongoing climate change.

One of the most brutal heatwaves to impact Western Europe in the last 50 years contributed to breaking climate records for the continent, according to Copernicus.

Western Europe experienced its hottest June on record last month as a searing heatwave swept across a continent facing increasingly frequent and intense heat extremes, the European Union’s (EU) climate monitor said Thursday. The report comes as a new heatwave is battering Europe this week, following a record-breaking one in June and an unusually early spring hot spell in May. The average temperature in western Europe reached 20.74 degrees Celsius in June, more than 3℃ above the 1991-2020 norm, according to the EU’s Copernicus Climate Change Service. It broke the region’s previous record set in June 2025. “We will see more heatwaves in a warmer world,” said Samantha Burgess, strategic climate lead at the European Centre for Medium-Range Weather Forecasts (ECMWF), which operates Copernicus. “They will be more intense and they will last longer, and they will impact more geographical areas,” Burgess told AFP. It was the second hottest June on record for the world and for Europe as a whole, Copernicus said, as human-induced climate change continues to push temperatures higher. Global temperatures in June were 1.39℃ above the estimated pre-industrial average, a period covering 1850-1900, according to Copernicus. The world’s oceans experienced their highest June temperatures on record, against a backdrop of the warming El Nino weather pattern which is developing and is forecast to strengthen in the tropical Pacific. “We’re at a transition point where climate change is shifting from being an abstract statistical future problem that you read about in reports, to a concrete present and disruptive feature of daily life,” Burgess said. ‘Heat dome’ Europe is the world’s fastest-warming continent, and changes in atmospheric circulation are fuelling more frequent and more intense heatwaves there. June was particularly brutal for Europe as a “heat dome” — a high-pressure system acting like a lid on a boiling pot — led to all-time and monthly temperature records in several countries. Thousands of deaths were linked to the heatwave — mostly in France, Spain and Belgium. More than two-thirds of Europeans — 410 million people — endured temperatures topping 35℃ during the June 15-30 heatwave, according to an AFP analysis. The June heatwave “contributed to severe health impacts, including heat-related deaths”, Copernicus said. Nearly 300 million people, including 100 million children and elderly people, may have been exposed to harmful levels of ozone pollution during the punishing June heat, according to a report from NGO Global Witness exclusively shared with AFP. High rates of humidity were one of the reasons why the June heatwave was so intense, Burgess said. “It was extremely humid, which then meant we people didn’t get relief at night. So we had a number of tropical nights in a row,” she said. The Mediterranean experienced its own record-breaking marine heatwave, with the continent’s Atlantic coasts also hit by hot spells, putting ecosystems at risk. “When the sea is warm, we get less alleviation at nighttime because there’s no coolness coming from the ocean. There’s no sea breeze,” Burgess said. Dry conditions raised drought risks in eastern Europe and contributed to wildfire activity in the Iberian Peninsula and southern France, Copernicus said. Older buildings World Weather Attribution, a network of climate scientists, said last month that Europe’s June heatwave was the “most severe ever recorded” based on a three-day forecast of average peak temperatures over the region studied. Such a heatwave would have been “virtually impossible” without the influence of climate change, they said. A similar event in June 2003 would have been about 2℃ cooler. Burgess said Europe needs adaptation plans to cope with climate change. “Many amazing buildings across Europe were built hundreds of years ago, and that climate no longer exists,” she said. The world, Burgess said, needs to get to net-zero emissions from the burning of fossil fuels as soon as possible. “Heatwaves will only get worse the more [emissions from] fossil fuel we pump into the atmosphere,” she said.

Western Europe just experienced its warmest June on record, EU scientists confirmed on Thursday, after an extreme heatwave at the end of the month smashed temperature records, disrupted power supplies and shut schools. Last month was also the second-warmest June globally, and the planet experienced the highest June sea surface temperatures since records began, the […]
