London:  England is preparing for its fourth heatwave of the summer, with temperatures expected to peak at 34°C in southern and eastern regions over the coming days. Forecasters predict the hottest conditions in areas such as Berkshire, Oxfordshire, and Heathrow, with highs of 33–34°C likely in parts of Lincolnshire, South Yorkshire, and East Anglia on Wednesday. London and East Anglia may experience temperatures of around 29–30°C on Thursday.

The UK Health Security Agency (UKHSA) has issued amber heat health alerts from 9 am Tuesday to 6 pm Wednesday, covering London, the East and West Midlands, East of England, and the South East. Yellow alerts have been put in place for the rest of England, including the South West, Yorkshire and Humber, and northern regions. Officials warn of increased health risks, particularly for older adults, people with pre-existing medical conditions, and other vulnerable groups, while also highlighting potential strain on health and social care services.

The extreme temperatures come amid worsening drought conditions, with several areas officially designated as being in drought. Water shortages are affecting crops, livestock, and wildlife, and the risk of wildfires remains high. Grass fires were reported in east London’s Wanstead Flats on Monday, and a large blaze in Dorset forced the evacuation of about 20 homes.

Experts link the rising frequency and severity of UK heatwaves to climate change. This summer has already seen three significant heat events, contributing to hundreds of heat-related deaths in the country. Across Europe, more than 2,300 fatalities have been recorded during this year’s extreme heat. Concerns are also mounting over housing infrastructure, with studies showing that one in five homes in England suffers from overheating, leaving many residents vulnerable during prolonged hot spells.

Authorities are urging the public to stay hydrated, avoid direct sun exposure during peak hours, check on vulnerable neighbours and relatives, and take precautions to prevent fires in dry outdoor areas.
