Meteorological Office Confirms New National Temperature Record

The Met Office has confirmed a new national temperature record after thermometers soared to 40.3°C in Coningsby, Lincolnshire. This surpasses the previous record of 38.7°C, set in Cambridge in 2019. The reading was taken at 15:25 BST on Tuesday, marking a significant milestone in the UK’s meteorological history.
The heatwave has brought unprecedented temperatures across the UK, with numerous locations exceeding their previous highs. Heathrow Airport recorded 40.2°C, while other regions also experienced extreme heat. The Met Office has attributed the intense heat to a combination of climate change and high-pressure systems.
Professor Stephen Belcher, the Met Office’s chief scientist, stated that the record-breaking temperature is a stark reminder of climate change’s impact. “These temperatures are not just a one-off,” he said. “They are part of a pattern we expect to continue as our climate warms.”
The UK Health Security Agency has issued a level 4 heat-health alert, the highest possible, urging the public to take precautions. Hospitals have reported an increase in heat-related illnesses, particularly among the elderly and vulnerable. The government has advised people to stay hydrated, avoid direct sunlight, and check on neighbours.
The record temperature has also raised concerns about infrastructure resilience. Transport networks, including roads and railways, have experienced disruptions due to the extreme heat. Network Rail has implemented speed restrictions on certain lines to prevent buckling of tracks.
The Met Office continues to monitor the situation closely, with forecasts indicating that temperatures may remain high for the next few days. The public is advised to stay updated with the latest weather information and follow safety guidelines.
Historic Heatwave Prompts Urgent Health Warnings Across the UK

The UK has recorded its highest-ever temperature as the ongoing heatwave continues to break records. The Met Office confirmed a provisional temperature of 40.3°C in Coningsby, Lincolnshire, surpassing the previous record of 38.7°C set in Cambridge in 2019.
