The UK is bracing itself for its hottest day on record as a red warning for extreme heat has been extended to cover an even larger area of England. Temperatures could soar to a staggering 38 degrees Celsius in some parts, prompting widespread concern and a heightened level of alert from the Met Office.
The red warning, which signifies 'danger to life', now encompasses significant urban centres and densely populated regions across central, eastern, south-eastern England, and beyond. This includes major cities and key infrastructure, where the effects of extreme heat can be particularly acute.
While the most severe heat is forecast for England, temperatures are also expected to be above average in Scotland and Northern Ireland, with parts of southern Scotland potentially reaching high 20s Celsius. In contrast, England's Midlands, East Anglia, and South East are at risk of the record-breaking 38C peak.
The extreme weather has major implications for public health, infrastructure, and daily life. Health services are preparing for an increase in heat-related illnesses, particularly among vulnerable groups such as the elderly, young children, and those with pre-existing conditions.
Infrastructure risks include buckling tracks on railways, melting road surfaces, power networks under strain due to increased demand, and potential water supply pressure. Authorities advise staying hydrated by drinking plenty of water, avoiding strenuous activity between 11 am and 3 pm, seeking shade, wearing loose light clothing, and checking in with vulnerable neighbours.
Wind speeds across the UK will be light during this period, ranging from 5-15 mph, offering little respite from the intense heat. The lack of air movement can trap warmth in urban areas, exacerbating the feeling of heat.
