London — The United Kingdom has recorded its hottest May temperatures ever, with parts of London reaching a staggering 35.1°C as an unprecedented spring heatwave sweeps across the country.

The Met Office confirmed that the latest temperatures broke the previous May record for the second consecutive day, raising fresh concerns over the growing impact of climate change on Britain’s infrastructure, public health, and daily life.

Across England, packed beaches, overcrowded parks, and soaring overnight temperatures created conditions more commonly associated with southern Europe than late spring in the UK. Heathrow and Kew Gardens were among the hottest locations recorded during the extreme weather event.

Weather experts have now issued thunderstorm warnings for several regions as unstable atmospheric conditions threaten flash flooding, lightning strikes, and travel disruption following days of intense heat.

Health officials extended amber heat-health alerts across multiple regions, urging vulnerable residents to remain indoors during peak temperatures and stay hydrated. Emergency services also warned the public against swimming in open water after several tragic drowning incidents were reported during the bank holiday period.

Climate scientists say the heatwave is another sign that the UK is entering a “new climate reality,” where extreme weather events are becoming more frequent and more severe.

Environmental analysts argue that many British homes, schools, hospitals, and transport systems were designed for cooler conditions and are now struggling to cope with rapidly rising temperatures.

The latest heatwave has reignited political debate over climate adaptation policies, renewable energy investment, and the government’s long-term environmental strategy.

Meanwhile, transport operators introduced temporary speed restrictions on some rail services due to overheating tracks, while retailers reported surging demand for fans, bottled water, and cooling equipment.

Forecasters expect temperatures to gradually ease later this week, although experts warn that future heatwaves could become increasingly common during British summers.

Authorities continue to monitor weather developments closely as millions across the UK brace for further disruption.
