Western Europe records its hottest June as heatwaves surge: EU monitor

Lead

Western Europe experienced its hottest June on record, according to the European Union's Copernicus Climate Change Service, as a heatwave at the end of the month broke temperature records in several countries. The announcement came as Europe faced yet another heatwave, the third since May, and as wildfires ravaged parts of France and Spain.

Coverage Comparison

Reports from multiple outlets, including France 24, The Hindu, Dawn, RFI, and Deutsche Welle, detailed the findings from Copernicus. The average temperature in western Europe reached 20.74 degrees Celsius in June, more than 3 degrees Celsius above the 1991-2020 norm, as reported by these sources. The Guardian provided a slightly different figure, noting the region's temperature was 3.06 degrees Celsius above the average from recent decades.

The reports concur that this June broke the previous record set in June 2025, when temperatures were 2.81 degrees Celsius above the average. Copernicus defines western Europe as stretching from Spain and the United Kingdom eastwards to Italy, Germany, and part of Austria.

Several outlets, including Dawn, France 24, and The Hindu, emphasized that this was the world's second-hottest June on record, as well as the second-hottest for Europe as a whole. The Guardian reported that globally, June 2026 was 0.56 degrees Celsius hotter than the 1991-2020 average and 1.39 degrees Celsius hotter than pre-industrial levels, making it the second-warmest June on record.

All sources attributed the extreme heat to human-induced climate change, with Samantha Burgess, strategic climate lead at the European Centre for Medium-Range Weather Forecasts (ECMWF), which operates Copernicus, providing commentary. She noted, as quoted by multiple outlets, that "June 2026 underscored how profoundly the climate is changing," and that "the result is increasingly intense heatwaves, a persistently warm ocean, and growing risks for people, ecosystems and infrastructure across Europe and beyond."

Key Claims

• Western Europe's hottest June: The average temperature in western Europe reached 20.74 degrees Celsius in June, more than 3 degrees Celsius above the 1991-2020 norm, according to Copernicus data reported by RFI, Dawn, France 24, The Hindu, and TASS.

• Previous record broken: The record set in June 2025, when temperatures were 2.81 degrees Celsius above the average, was surpassed, as noted in the RFI report.

• Second hottest globally and for Europe: It was the second-hottest June on record for the world and for Europe as a whole, as reported by Dawn, The Hindu, and France 24.

• Thousands of deaths linked: Reports from Dawn, France 24, and The Hindu, citing Copernicus and other data, linked thousands of deaths to the heatwave, mostly in France, Spain, and Belgium. The Guardian reported that national authorities in France reported thousands of excess deaths, with hundreds in Spain, the Netherlands, and Belgium. Deutsche Welle's report focused on Germany, where the Robert Koch Institute announced at least 5,120 heat-related deaths so far this year, most of them people aged 75 and older.

• Global ocean heat record: The world's oceans experienced their highest June temperatures on record, according to reports from The Guardian, Dawn, The Hindu, France 24, and others, with TASS reporting that the global ocean surface average temperature in June reached a record high of 20.98 degrees Celsius, breaking the previous record set in 2024.

• Europe is the world's fastest-warming continent: This was reported by Dawn, France 24, The Guardian, and The Hindu, citing Copernicus, with changes in atmospheric circulation fueling more frequent and intense heatwaves.

• A heat dome was the cause: A "heat dome" high-pressure system, acting like a lid on a boiling pot, led to all-time and monthly temperature records in several western European countries, as reported by Dawn, The Hindu, and France 24.

• Global temperature and pre-industrial: Global temperatures in June were 1.39 degrees Celsius above the estimated pre-industrial average (1850-1900), as reported by The Guardian, Dawn, The Hindu, and France 24.

Perspectives

Samantha Burgess of the European Centre for Medium-Range Weather Forecasts, which operates Copernicus, emphasized the severity of the situation. She told AFP, as quoted by Dawn and The Hindu, "We will see more heatwaves in a warmer world. They will be more intense and they will last longer, and they will impact more geographical areas." She also described the shift from "an abstract statistical future problem" to "a concrete present and disruptive feature of daily life."

The Robert Koch Institute (RKI), Germany's main public health institute, highlighted the human impact, announcing that at least 5,120 heat-related deaths had occurred in Germany so far this year, most during the June heatwave, as reported by Deutsche Welle.
