Hottest June on record in Western Europe as heatwaves hit continent

Western Europe experienced its hottest June ever recorded, with temperatures exceeding the 1991-2020 average by more than 3°C, according to the EU's Copernicus Climate Change Service. The heatwave, linked to thousands of deaths, also drove global and ocean temperatures to record highs, prompting warnings of more frequent and intense heat extremes.

Western Europe Swelters Through Hottest June on Record

Western Europe experienced its hottest June on record this year, according to the European Union's Copernicus Climate Change Service, as a searing heatwave swept across the continent and contributed to thousands of deaths, mostly in France, Spain and Belgium. The average temperature in the region reached 20.74°C (69.33°F) in June, more than 3°C above the 1991-2020 norm, and broke the previous record set in June 2025.

The extreme heat was part of a broader pattern of rising global temperatures. Copernicus reported that globally, the average temperature for June was 16.54°C (61.77°F), which is 0.56°C (1°F) above the 1991-2020 average. The month was also 1.39°C (2.5°F) warmer than the estimated pre-industrial June average for the 1850-1900 period. Additionally, the average sea surface temperature across oceans outside the polar regions reached 20.86°C (69.55°F) in June, the highest ever recorded for that month.

The heatwave created a "heat dome" effect, a high-pressure system that acts like a lid on a boiling pot, according to Copernicus. The dry conditions in southwestern Europe also prompted wildfires. More than two-thirds of Europeans – 410 million people – endured temperatures topping 35°C (95°F) during the June heatwave.

The record-breaking June heat followed a succession of extreme weather events, highlighting challenges expected in the future. Europe is the world's fastest-warming continent, and changes in atmospheric circulation are causing more frequent and more intense heatwaves. Samantha Burgess, strategic climate lead at the European Centre for Medium-Range Weather Forecasts (ECMWF), which operates Copernicus, told AFP: "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."

Copernicus also noted that it was the second hottest June on record for the world and for Europe as a whole, as human-induced climate change continues to push temperatures higher. The report comes as a new heatwave is battering Europe this week, following the record-breaking June and an unusually early spring hot spell in May.

What was claimed, and who backed it

Each row is one claim, attributed to the outlet whose wording states it most clearly. Confidence rates how directly the source text states the claim — explicit and unhedged rates high; hedged, pieced-together, or internally inconsistent statements rate lower. It does not measure whether the claim is true. Status counts the distinct outlets we found asserting it — so a single-source claim can still show high confidence, and a multi-source claim can show medium. Every one of those outlets is named beside the status, so you can check the count against the list. For claims extracted before we began storing that list, the row says so: it names the outlet the claim is quoted from and states that we have not recorded which outlets backed it. Outlets wrote at different times, so a figure that evolves — a casualty count, for example — can legitimately differ between rows; check the "as of" time next to each claim's source.
