Thermal imaging captured across London on Wednesday revealed surface temperatures soaring between 50 °C and 65 °C, marking an unprecedented heat event in the capital.
Busy intersections such as Oxford Circus and Piccadilly Circus recorded pavement temperatures of 56 °C, exposing commuters to extreme heat while navigating the city’s streets.
Nearby Regent Street reached 57 °C, and an Overground platform at Highbury & Islington recorded a peak of 62 °C. The plaza outside King’s Cross station fluctuated between 54 °C and 62 °C under direct sunlight.
A road‑works site in Holborn measured an astonishing 65 °C, while Gray’s Inn Road’s pavement hit 59 °C. Inside a Victoria line carriage, the floor temperature climbed to 40 °C, and an Islington playground registered 53 °C in the late afternoon.
Mel Evans, head of climate at Greenpeace UK, described the heatwave as a public‑health emergency, emphasizing that the extreme temperatures are driven by fossil‑fuel emissions and demand immediate action.
She called for a comprehensive extreme‑heat strategy that includes cooling homes and schools, establishing safe work‑site limits, expanding shade and green spaces, and protecting the most vulnerable populations.
The city’s mayor echoed these concerns, stating that London is not equipped to handle frequent, severe heatwaves and outlining a new heat‑response plan aimed at bolstering urban resilience.
Met Office projections suggest that temperatures as high as 45 °C could become plausible by 2056, with the possibility of nine consecutive days exceeding 40 °C in future decades. Chief scientist Stephen Belcher warned that human‑induced climate change makes such events more likely and intensifies their health and infrastructure impacts.
The current heatwave underscores the urgent need for both mitigation of greenhouse‑gas emissions and adaptation measures to safeguard public health and city services against a warming climate.
