Danger of death: UK bakes as third heatwave continues to sweep country - when will the weather break?

As the UK’s third heatwave of the year so far continues to sweep the country, warnings of an ‘increased risk of death’ have been issued. Temperatures reached 34.7C at Astwood Bank, near Worcester, on Friday (July 11), the Met Office said, with similar or even higher temperatures expected on Saturday (July 12).

Meteorologist Greg Dewhurst said: “It might be plus or minus half a degree higher or lower [on Saturday], probably maybe a little bit higher, but that’s going to be the peak as then temperatures start coming down a little bit through the second half of the weekend as low pressure slowly starts to edge in.”

On Friday, Wales recorded its hottest day of the year with 32.4C in Cardiff’s Bute Park, and temperatures have widely reached the high 20s across the country. Even the Scottish Highlands had very hot weather, with a high of 28.9C in Aboyne, a village in Aberdeenshire.

Amber heat health alerts are in place for the Midlands and southern and eastern England until 9am on Monday, warning of the potential for a rise in deaths, particularly among those aged 65 and over or with health conditions.

Fire chiefs have urged people to stay safe as they warned of the increased risk of wildfires and drowning during the heatwave. The London Fire Brigade said it has responded to 24 wildfires this year, five of which occurred this week, including one in Manor Park, east London, on Friday afternoon, where 70 firefighters fought to tackle a grass fire on Wanstead Flats. The risk of wildfires in London is currently rated at “severe” by the Natural Hazards Partnership.

The National Fire Chiefs Council (NFCC) have also asked people not to enter water to try to cool down and urged parents and carers to ensure children are supervised around water at all times. Phil Garrigan, NFCC chairman, said: “We are urging people to take simple but vital safety precautions to protect themselves and their loved ones during this period of hot, dry weather.

“Our experience tells us that wildfires can start in an instant and escalate rapidly. That’s why we’re asking everyone to stay alert and act responsibly.”

HM Coastguard also issued safety advice for people heading to the coast, as data from the water incident database shows most drownings occurred in July over the last three years. Meanwhile, the RNLI warned beachgoers that, despite the heat, there is still a risk of cold water shock.

Ross Macleod, the charity’s water safety manager, said: “Even in hot weather, the seas around our coasts are cold enough year-round to trigger cold water shock, while waves and rip currents can overpower even the most experienced water users.”

He added: “We encourage people to choose a lifeguarded beach and swim between the red and yellow flags, which is the area most closely monitored by the lifeguards.”

As well as the amber alerts, the UK Health Security Agency (UKHSA) has yellow alerts in place until Monday for the North East, North West and Yorkshire and Humber.

When will heatwave end?

The third heatwave of the summer is set to peak on Saturday, forecasters said, with highs of more than 34C possible in parts of the UK. The Met Office said that though temperatures may peak on Saturday, it will remain “very warm” across the country on Sunday.

“We’re probably looking at maximum temperatures around 30C, 31C degrees across central and southern England, but still widely across the whole UK, mid to high 20s,” Mr Dewhurst said.

“It could still get to around 29 or 30C across southeast England on Monday, and then everyone into the fresher air by Tuesday, temperatures more like 23C, 24C as the maximum temperature.”
