Western Europe has experienced its hottest June on record, according to scientists, as the United Kingdom enters its third heatwave of the year and wildfires continue to devastate France and Spain. The EU's Copernicus climate monitoring service reported that surface air temperatures for the region were 3.06 degrees Celsius above the average from recent decades, driven by carbon pollution.
Global and Regional Temperature Records
Globally, June 2026 was 0.56°C hotter than the 1991-2020 average and 1.39°C hotter than preindustrial levels, making it the second-warmest June on record. The planet's oceans also reached unprecedented temperatures. Samantha Burgess, a climate scientist at Copernicus, stated, "Together, these records reflect a climate system continuing to accumulate heat. The result is increasingly intense heatwaves, a persistently warm ocean, and growing risks for people, ecosystems and infrastructure."
Wildfires Ravage Southern Europe
Raging wildfires have destroyed large areas of southern Europe, prompting the EU to deploy firefighters and water-bearing planes to assist national services overwhelmed by simultaneous blazes. Data from the European Forest Fire Information System shows that EU wildfires have burned 56% more land than usual. In France, 35,400 hectares (87,474 acres) have burned—four times the average for this time of year—while Spain has seen 55,128 hectares (136,224 acres) burned, double the average.
Barcelona set a new heat record on Wednesday with temperatures of 40.5°C, according to Spanish meteorologists. In France, a 22-year-old firefighter died after battling a blaze in the Alps, as reported by the French interior ministry.
UK Heatwave and Sleep Deprivation
In the UK, Met Office scientists warned of an "extreme" marine heatwave, with daytime temperatures on land expected to reach 34°C on Thursday. The high temperatures are forecast to persist over a sweltering 10 days. A defining feature of June's heatwave was "exceptionally warm" overnight temperatures, leading to the highest average June minimums on record. A poll found that two in three people struggled to sleep due to the heat, causing "mass sleep deprivation."
Stephen Belcher, chief scientist of the Met Office, remarked, "To see temperatures like this in the UK in June is sobering. Events like this bring home the implications of climate change."
Fire Risk and Prevention
The UK's National Fire Chiefs Council (NFCC) urged people to take extra care outdoors as the heatwave increases the risk of fast-spreading wildfires. Fire services have responded to numerous wildfires across southern and eastern England in recent weeks. Dave Swallow, a tactical adviser at the NFCC, said, "Most wildfires start because something provides the spark: a disposable barbecue left behind, a discarded cigarette or even a glass bottle left in the sunshine. We all have a role to play in preventing them."
Health Impacts and Adaptation
The World Health Organization estimates that 200,000 people have died from heat in Europe over the last four years, with most deaths considered "entirely preventable." Experts recommend installing air-conditioning for vulnerable groups, shading buildings with awnings and external shutters, providing cooling centres, and bolstering health systems.
Tree shade can significantly cool neighbourhoods during hot weather, but new analysis shows the UK lags behind its European counterparts. The average UK urban area is just 18% tree-covered, compared with a European city average of about 30%, according to the Energy and Climate Intelligence Unit (ECIU). Of 47 UK cities and urban areas in the dataset, 45 fall below the European average. London has 18% tree cover, Burnley has 11%, and Guildford leads with 37%. In contrast, Barcelona has 31% and Nice 39%. The UK ranked 31st out of 38 countries overall.
Tom Cantillon, an analyst at the ECIU, noted, "Planting trees can over time help to bring down temperatures in the buildings they shade, and give more vulnerable people hope of being able to leave their homes into less risky temperatures to do things like shop and visit the GP. The UK is way behind."
