The UK’s new record-high temperature of 40.3°C at Coningsby, Lincolnshire, has been confirmed by the Met Office, following a rigorous process of analysis and quality control.

The confirmation comes as quality control testing, including physical inspections, cross-checking of stations and sites and further testing of equipment was carried out on a number of sites where records were provisionally broken.
The quality control measures are in accordance with the internationally-agreed World Meteorological Organisation (WMO) standards, which are required to be accepted as official records.
Record-high temperature records have also been verified for Wales, with 37.1°C at Hawarden Airport, Flintshire, on 18 July now verified. All appropriate standards have also been met to confirm a new record high temperature for Scotland of 34.8°C at Charterhall on 19 July.
New highest daily maximum temps. UK and England - 40.3C at Coningsby. Wales - 37.1C at Hawarden. Scotland - 34.8C at Charterhall.
A new record high daily minimum temperature for Wales of 24.5°C at Aberporth on 19 July has also been confirmed.
The extreme temperatures were recorded as the UK was impacted by an unprecedented heatwave, with the previous UK temperature record of 38.7°C provisionally met or exceeded at 46 stations, from Kent to North Yorkshire and from Suffolk to Warwickshire. Provisionally, seven stations recorded maximum temperatures in excess 40°C.
Dr Mark McCarthy of the National Climate Information Centre said:
“Verification of these record-breaking temperatures confirms what we’ve been saying in the last week, that the UK exceeded 40°C for the first time as part of a widespread and intense heatwave.
“In a climate unaffected by human-induced climate change, it would be virtually impossible for temperatures in the UK to reach 40°C but climate change is already making UK heatwaves more frequent, intense and long-lasting.”
