What we know about Europe braces for another summer heatwave

Much of Europe is currently bracing for another intense summer heatwave, following a series of record-breaking droughts that have driven major rivers to historic lows, ignited devastating forest fires, and contributed to thousands of excess deaths across the continent. This latest surge in temperatures arrives as Europe continues to grapple with the consequences of being the fastest-warming continent on the planet, a trend experts attribute directly to human-caused climate change.

Swathes of Britain and France were placed under extreme heat warnings on Monday, with forecasts predicting temperatures reaching the mid-30s Celsius. Simultaneously, parched conditions have triggered new fire outbreaks in Greece and Spain. According to data released by Europe’s Copernicus climate observatory on Monday, the heatwave follows a July that saw mainland France and Switzerland experience their most widespread droughts on record. Nearly 120 million Europeans now live in regions where July 2026 was the hottest month ever recorded, according to an AFP analysis of national weather agency data.

Europe’s weather warning system, MeteoAlarm, reported on Monday that scorching temperatures are already impacting much of Italy and the coastal regions of Croatia. Unusually high temperatures are also expected in the coming days across nations not typically accustomed to such extremes, including Switzerland, Austria, and Hungary. The United Kingdom’s Met Office warned over the weekend that the nation’s fifth hot spell of the summer was taking hold, noting that the country’s infrastructure was originally designed for a more temperate, cooler climate.

The water crisis in the United Kingdom remains severe, with nearly three-quarters of England and the entirety of Wales officially in drought. More than 27 million people are currently under water-use restrictions, and the environment department warned on Monday that all regions of the country are experiencing significant pressure on their water resources. With next to no rain forecast for these areas this week, the situation remains critical for both residents and local ecosystems.

In France, the national weather agency, Meteo-France, issued warnings on Monday that the southeast would see temperatures as high as 35C, with heat expected to spread further across the country as the week progresses. The agency cautioned that due to climate change, future summers will generally be hotter than those experienced to date. The French environment ministry added that nearly 70 percent of the country is now subject to water-use restrictions, prioritizing essential needs such as healthcare, sanitation, and drinking water.

The human toll of these extreme conditions continues to mount. An AFP analysis of national statistics found that at least 12,000 excess deaths were recorded across nine European countries during a single heatwave in June, a figure that is expected to rise as more data becomes available. Both France and the UK have seen thousands of excess deaths during previous heatwaves this year, highlighting the lethal impact of these recurring temperature spikes on vulnerable populations.

Wildfire risks remain extreme across the continent. Greece reported its second major fire of the season near Athens on Monday, prompting the deployment of hundreds of firefighters and specialized equipment. This follows a blaze that broke out 10 days ago northwest of the capital, which has already blackened more than 10,000 hectares of pine forest. Meanwhile, in southwestern Spain, firefighters are struggling to contain a rapidly expanding blaze that has forced the evacuation of approximately 800 people, with local officials stating that the weather is offering no respite.

The environmental impact extends to Europe’s vital waterways. Heat and drought are driving rivers to record lows, with industry groups warning on Monday that the Rhine in Germany could soon become unnavigable. In Poland, officials announced that the Vistula, the country’s longest river, matched its record low in Warsaw on Monday, a record that had been set only the previous Friday. Low levels along the Danube river previously forced Hungary and Romania to consider shuttering nuclear plants that rely on the water for cooling, though both managed to avoid such measures in late July.

As the continent faces these challenges, the European Space Agency’s observatory in Teruel, Spain, is preparing for a scheduled eclipse event. The area saw temperatures breach 30C on Monday, and the eclipse path will cross regions recently devastated by Spanish wildfires. According to an AFP analysis, 95 percent of mainland France and 99 percent of Switzerland saw drought conditions in July, both record figures since the European Drought Observatory began collecting data in 2012. The eclipse is set to begin at 7:33 pm CEST (1733 GMT), reaching totality at 8:23 pm.

Already, more than 10,000 hectares (24,700 acres) of pine forests were blackened by a blaze that broke out 10 days ago northwest of the capital.

The records were concentrated in southern Britain, western France, and northern and eastern Spain.
