How long is the heatwave going to last in the UK?

  • Britain is preparing for its third heatwave of the year, which forecasters predict will be prolonged, potentially lasting into mid-July, though not as extreme as the June heatwave.
  • Temperatures are expected to peak at around 34C in the South East by Thursday or Friday, with southern and eastern England likely to exceed 30C, while other regions will see temperatures in the low to high 20s.
  • Yellow heat health alerts have been issued by the UK Health Security Agency (UKHSA) for the Midlands and southern England until Saturday evening, indicating potential impacts on health and social care services.
  • The UKHSA warns of increased risks for vulnerable individuals, including the elderly and those with underlying health conditions, due to heat-related illnesses and a higher potential for water-related incidents.
  • This follows two previous heatwaves this year, with the last one prompting rare red warnings for extreme heat, and the current weather event is attributed to a 'heat dome' moving across Europe, which has already caused over 1,300 heat-related deaths on the continent.
