Unprecedented Temperatures Across the UK
England experienced its warmest June on record, with the mean temperature reaching 17.1°C, nearly 3°C above the average. This made it the second warmest June for the entire United Kingdom. The elevated temperatures were consistent throughout the day and night, frequently featuring 'tropical nights' where temperatures did not fall below 20°C, significantly contributing to the high monthly average.
A new UK record for June was established on Friday, June 26, 2026, when Lingwood, Norfolk, registered 37.7°C (99.9°F). This surpassed the previous record of 35.6°C (96°F) set in 1957 and equaled in 1976. In response to the severe conditions, a rare red extreme heat warning was issued for parts of England and Wales, remaining in effect for an unprecedented three consecutive days in some eastern English regions.
Wales also marked its second warmest June on record, with Cardiff reaching a new June high of 35.9°C (96.6°F) on Thursday, June 25, exceeding its prior record of 33.7°C (92.6°F). Northern Ireland also equaled its June record, with Castlederg, County Tyrone, recording 30.8°C (87.4°F).
These June records follow a hot May, which saw temperatures hit 35.1°C in Kew, London, breaking the previous May record of 32.8°C from 1922 and 1944.
Europe Also Grapples with Extreme Heat
The intense June heatwave was not confined to the UK, impacting a large portion of Europe. Numerous countries, including Hungary, Austria, the Netherlands, Switzerland, and Denmark, reported new June temperature records. France recorded its highest-ever daily average temperature, surpassing 30°C for the first time, exceeding the heatwaves of August 2003 and July 2019, according to MeteoFrance.
Human Impact and Future Outlook
Preliminary data indicates a significant human toll from this recent heatwave. France's national health ministry reported approximately 1,000 excess deaths, predominantly among individuals over 65. Spain attributed 1,029 excess deaths to the extreme heat. The full extent of the impact across Europe is still being assessed, though it is not anticipated to reach the scale of the August 2003 heatwave, which resulted in an estimated 30,000 to 70,000 fatalities.
Following the 2003 event, there was increased awareness regarding the dangers of heatwaves, leading to the implementation of extreme heat warnings by national weather forecasting agencies to mitigate adverse effects.
Scientists note that heatwaves are becoming more frequent and severe due to climate change. Spanish forecasters have observed that half of the 12 June heatwaves recorded in Spain since 1975 have occurred within the last decade.
