Week-long heatwave due in England with 34C peak in south-east

Week-long heatwave due in England with 34C peak in south-east

Week long heatwave due in England - Health officials have activated a week-long alert starting at midday on parts of the UK, warning of potential health risks during an upcoming heatwave. The Met Office predicts that temperatures in the southern regions could climb to 28C on Saturday, with the south-east of England expected to see highs of 29C on Sunday. The peak of the heatwave, however, will arrive by Thursday or Friday, when temperatures are forecast to hit 34C, the highest recorded for this period. This sustained period of extreme heat is anticipated to last around seven days, affecting multiple areas across the country.

“We have got a heatwave on the way across parts of southern England and Wales, temperatures are already quite high across the south-east today. We could get 28C in London,” said Met Office meteorologist Becky Mitchell. She added that while other regions may experience milder conditions closer to average, the temperatures will gradually rise as the week progresses. “At the start of next week, we will see temperatures approach the low 30s,” Mitchell noted, highlighting a north-south temperature divide with cloudier conditions in the northern areas.

The UK Health Security Agency (UKHSA) has issued yellow heat health alerts covering the east, East Midlands, West Midlands, south-west, London, and south-east of England. These alerts are valid from midday on 4 July until 8pm on 11 July, signaling that high temperatures could place vulnerable individuals at a heightened risk of heat-related illnesses. The agency emphasized that while the impacts are expected to be moderate, they include increased demand on healthcare services, potential dehydration, and a greater likelihood of cold water shock incidents.

“Within the warning area, the high temperatures are likely to have minor impacts on health and social care services, including the increased use of healthcare services by vulnerable people and a greater risk to life for the same group,” the UKHSA stated. The agency also warned of an uptick in water-related incidents, such as drownings, due to the combination of high temperatures and the risk of sudden immersion in cooler water.

Meanwhile, Southern Water has imposed a hosepipe ban from 12.01am on 10 July in Hampshire and the Isle of Wight. The restriction applies to non-essential water use, including watering gardens via sprinklers, filling paddling pools or pools, and washing vehicles or outdoor surfaces. This measure aims to conserve water resources during the extended period of high temperatures and increased evaporation.

The current heatwave follows a recent spell of extreme weather, during which the Met Office issued a rare red warning for extreme heat across parts of the UK. This marked the first time since extreme heat warnings were introduced in 2021 that three consecutive days saw a red alert. Records dating back several decades, and in some cases over a century, were either matched or surpassed during this event. For example, the UK set a provisional June temperature record of 37.7C in Lingwood, Norfolk, which surpasses the previous record of 35.6C from 1976 by more than 2C.

“The peak of the heat appears to be Thursday or Friday: 34C in the south-east,” Mitchell said, contrasting the current situation with last month’s heatwave. “This heatwave won’t be as hot and humid as June’s, but it will be a prolonged spell of hot weather, lasting around a week.”

While the UKHSA has not issued warnings for Wales, the potential for similar conditions remains. The agency’s latest alerts underscore the growing frequency and intensity of heatwaves globally, with projections indicating that such events will become more common in the UK’s future climate. The Met Office highlights that rising temperatures are expected to be most pronounced during the summer months, placing southern regions at particular risk. This trend aligns with broader climate change patterns, which have already contributed to more severe and prolonged heat events in recent years.

Experts suggest that the current heatwave is part of a larger pattern of climate shifts, which have led to increased heat extremes worldwide. The UKHSA and the Met Office are working together to monitor these conditions and provide timely guidance to the public. With the combination of high temperatures and the risk of prolonged exposure, authorities are urging residents to take precautions, particularly for those with pre-existing health conditions or limited access to cooling facilities.

The prolonged heat is also expected to affect daily activities, such as outdoor work, travel, and recreational pursuits. Mitchell noted that the south-east of England, including areas like London, will remain hotter than other parts of the UK, creating a stark contrast in weather conditions. This regional variation may lead to differing impacts on local communities, with some areas experiencing more severe effects than others.

As the heatwave progresses, officials are monitoring its effects on both health services and water supply systems. The hosepipe ban in Hampshire and the Isle of Wight is one of several measures being taken to manage the strain on water resources. Additionally, the UKHSA’s yellow alerts serve as a reminder that even moderate heat can pose challenges for those most at risk, including the elderly, young children, and individuals with chronic illnesses.

Climate scientists have warned that the UK is likely to see more frequent and intense heatwaves as global temperatures continue to rise. The Met Office’s projections indicate that southern regions, such as the south-east, will be especially vulnerable. These predictions come amid a growing body of evidence showing that extreme weather events are becoming more common, with heatwaves now occurring more frequently than they did a few decades ago. The recent record-breaking temperatures in June serve as a warning of what may be more frequent in the years to come.

Despite the challenges posed by the heatwave, authorities remain optimistic that the measures in place will help mitigate its impact. The UKHSA and the Met Office are collaborating closely to provide real-time updates and guidance, ensuring that the public is well-informed about the risks and how to stay safe. As the week unfolds, the focus will remain on monitoring temperature trends and adjusting response strategies accordingly.
