More than 2,700 deaths across England and Wales have been linked to unprecedented heatwaves during May and June 2026, according to a study released on July 13, 2026. Researchers from Imperial College London, the Met Office, and the London School of Hygiene and Tropical Medicine estimated that there were 550 heat-related deaths between May 21 and 29, and nearly 2,200 deaths from June 18 to 28.
Impact of Extreme Heatwaves in the UK
The UK experienced its hottest June on record, with temperatures soaring to 37.7C (99.9F). Mark McCarthy, science manager at the Met's climate attribution team, noted, “They were extreme heatwaves for the UK, and for all parts of Western Europe, and they’re particularly exceptional for the timing and how early in the year they occurred.”
The research highlights the growing impact of climate change on the frequency and intensity of heatwaves. Scientists estimate maximum daytime temperatures were up to 4C (7.2F) higher due to global warming. The UK Health Security Agency (UKHSA) is set to release its official estimates of heat-related deaths in the coming weeks.
Government Response to Climate Change
In light of these findings, the Climate Change Committee (CCC) warned that the UK is “not ready” to handle the consequences of climate change. A report published in May indicated that 92 percent of British homes could be too hot by 2050. The report urged the government to establish maximum temperature limits in workplaces and invest in air conditioning for public buildings, such as hospitals and schools.
Excess Deaths Across Europe
Data from EuroMOMO revealed that over 10,000 excess deaths occurred across Europe during these heatwaves, particularly among individuals aged 65 and older, with 9,000 excess deaths reported in that age range. This alarming trend underscores the urgent need for action as scientists pooled national mortality statistics from 27 European countries, linking the heatwave to a spike of 10,650 excess deaths from June 22 to 28.
- 550 deaths between May 21-29
- 2,200 deaths between June 18-28
- Temperatures reached 35.1C (95.2F) in May
