Britons prepare for heat wave ahead of surging temperatures

London is predicted to be hotter than the Caribbean, the Western Sahara and popular holiday destinations in Europe as temperatures soar. The Met Office has forecast the capital could see highs of 38C when the heatwave sweeps across England. The rise in temperatures has forced the UK Health Security Agency to issue a level 4 heat-health alert – described as an “emergency” – while the Met Office has issued the UK’s first red extreme heat warning, with both running from Monday to Wednesday.
