Britain will be gripped by a 35C heatwave from today bringing a ‘rise in deaths’ as the second five-day amber heat health alert in two weeks comes into force at midday.
The UK Health Security Agency (UKHSA) alert will last until Tuesday at 6pm and covers London, the East Midlands, South East, South West and East of England.
The alert covers Worthy Farm in Somerset, where the Glastonbury Festival is taking place and British band The 1975 are set to headline the Pyramid Stage this evening.
A yellow alert was also issued for Yorkshire and Humber and the West Midlands for the same time period amid fears of ‘significant impacts’ for health and social care.
Temperatures could hit 28C (88F) today in southern England, then rise to 30C (85F) tomorrow, 31C (88F) on Sunday, 35C (95F) on Monday and 30C (85F) on Tuesday.
If the mercury gets above 33.2C (91.8F) it would make it the UK’s hottest day of the year so far – beating the current record set last Saturday in Charlwood, Surrey.
An official heatwave is recorded when areas reach a certain temperature for three days in a row, with thresholds varying from 25C (77F) to 28C (82F) in different areas.
The UK’s first heatwave of the year began on June 20 in many parts of England. That period also saw the first amber heat-health alert issued since September 2023.

Met Office meteorologist Craig Snell said: ‘From Friday onwards we’re starting to once again see the heat build across England and Wales.
‘Scotland and Northern Ireland are going to have a slightly different few days, some parts of western Scotland could see some heavy rain, especially on Friday, and we could potentially see some further rain towards the end of the weekend.
‘On Friday, we’re likely to see temperatures potentially peak around 27C or 28C in central and southern parts of England, it’s going to feel quite humid.
‘On Saturday, the hottest weather will be in the south east, potentially 30C. On Sunday, we’re most likely to see somewhere around 30C or 31C.
‘It looks like the peak of the hot spell will be Monday, at the moment it’s looking between 32C and 34C, there’s a chance it’ll be hotter than the previous (heatwave).
‘Tuesday, some fresher air is going to spread across the country, but we’re potentially likely to see between 31C and 33C.’
Some parts of central and southern England might meet the heatwave criteria by Monday, Mr Snell added.
The Met Office forecast for London on Monday is currently 35C.
Mr Snell also said that as of Monday, some potential thunderstorms could move in, but it is too early to say where they might be.
Temperatures are likely to go back down to the mid-20Cs after Tuesday, which is still above average for the time of year, the forecaster said.
The UKHSA activated the amber alert amid concerns that there could be ‘a rise in deaths, particularly among those ages 65 and over or with health conditions’.

The warning said ‘significant impacts are likely across health and social care services due to the high temperatures’ along with ‘increased demand for power exceeding capacity’ and ‘heat affecting the ability of the workforce to deliver services’.
It told of ‘indoor environments overheating, increasing the risk to vulnerable people living independently in community and care settings’; and ‘internal temperatures in care settings may exceed recommended threshold for clinical risk assessment’.
There could also be ‘issues managing medicines’; ‘staffing issues due to external factors’; and ‘other sectors starting to observe impacts – for example, travel delays’.
Dr Agostinho Sousa, head of extreme events and health protection at the UKHSA, said: ‘We have already seen a spell of hot weather last week and temperatures are once again set to increase in the coming days, with central, southern and eastern areas of the country likely to see the biggest impacts.
‘Our findings show that heat, especially at the sort of temperatures we are likely to see at the beginning of next week, can result in serious health outcomes across the population, especially for older adults or those with pre-existing health conditions.
‘It is, therefore, important to check on friends, family and neighbours who are more vulnerable and to take sensible precautions while enjoying the sun.’
The National Pharmacy Association has advised patients to store their medicine away from heat zones and direct sunlight, warning that they can lose effectiveness or cause unwanted side effects.
Vice-chairwoman and pharmacist Sukhi Basra said: ‘It’s important we take sensible precautions, including double-checking that your medication is stored correctly in a cool dry place, as per any storage instructions, ideally below 25C, as well drinking plenty of fluids and keeping your homes cool in the hottest hours of the day.
‘We know the hot weather can be more of a challenge for older people or those with certain health conditions and it’s important people check on vulnerable friends, family and neighbours during this period.
‘If anyone has concerns at all about their health or their medication, please speak to your local pharmacy, who will be well placed to help.’
Meanwhile data from Virgin Media O2 has predicted network traffic will drop as Brits head outside to enjoy the sunshine this week.
Analysis of network traffic during the first heatwave earlier this month revealed that traffic fell by 7 per cent when the temperature hit 30C.
Its poll found 41 per cent of UK workers admit to having pulled a sickie to make the most of hot weather, with that figure soaring to six out of ten 18 to 24 year olds.

In Somerset today, music fans at the Glastonbury Festival can expect a clear morning at Worthy Farm and temperatures in the mid 20Cs.
Met Office spokesman Stephen Dixon said: ‘Friday should start relatively sunny, with temperatures reaching into the mid-20s. However, there will be a touch more cloud later in the day and into the evening.’
British pop rock band The 1975 will be the first headliners to grace the Glastonbury Festival’s Pyramid Stage this year when they perform this evening.
Made up of four school friends, the group, known for songs including Chocolate, Someone Else and About You, is comprised of singer Matt Healy, bassist Ross MacDonald, guitarist Adam Hann, and drummer George Daniel.
The five-day celebration of music and performing arts, which opened its gates on Wednesday, will also see headline performances from veteran rocker Neil Young and his band the Chrome Hearts, and US pop star Olivia Rodrigo.
The BBC confirmed yesterday that Young’s Saturday Pyramid Stage set will not be broadcast live ‘at the artist’s request’.
This year’s line-up features a number of acts listed as TBA, as well as a mysterious act called Patchwork, which will take to the Pyramid Stage tomorrow.
Among the music stars rumoured to be performing a secret set is New Zealand singer Lorde, whose fourth-studio album, Virgin, is set for release today.
The pop star posted a picture of the Woodsies stage to her Instagram account on Thursday, fuelling speculation that she could be the act listed as ‘TBA’ who will be performing at 11.30am.
Earlier in the month, she told BBC Radio 2 that she is ‘pretty keen’ to see if she can ‘pull some strings’ and make an appearance at this year’s festival.

Other performers today include: Irish singer CMAT; hip-hop star Loyle Carner; rock band English Teacher; indie band Wet Leg; and Canadian star Alanis Morissette, who will take to the Pyramid Stage after a TBA act which will be performing at 4.55pm.
Today’s line-up of events also includes a Q&A featuring Australian actress Margot Robbie at Pilton Palais and a Mountainhead Q&A with Jesse Armstrong, along with performances from psychedelic rockers Osees and Britpop veterans Supergrass.
Tomorrow will see Irish rap trio Kneecap, who have seen one of their members charged with a terror offence, perform on the West Holts Stage at 4pm.
Before the festival, Prime Minister Sir Keir Starmer said it would not be ‘appropriate’ for them to perform their slot at Worthy Farm.
Rapper Liam Og O hAnnaidh was charged for allegedly displaying a flag in support of proscribed terrorist organisation Hezbollah at a gig in London in November last year.
Last week, the 27-year-old, who performs under the stage name Mo Chara, was cheered by hundreds of supporters as he arrived with bandmates Naoise O Caireallain and JJ O Dochartaigh at Westminster Magistrates’ Court in ‘Free Mo Chara’ T-shirts.
He was released on unconditional bail until his next hearing at the same court on August 20.
Yesterday evening, the rap trio posted a film they executive produced to social media, titled Stop The Genocide, which includes testimonies from a Palestinian activist and plastic surgeon on the war in Gaza.
Performing in the coveted Sunday legends slot this year is Sir Rod Stewart, who previously said he will be joined by his former Faces band member Ronnie Wood, as well as some other guests.
Sir Rod’s performance will come after he postponed a string of concerts in the US, due to take place this month, while he recovered from flu.
Among the other acts expected to draw large crowds this year is pop star Charli XCX, who is engaged to The 1975 drummer Daniel and will perform songs from her sixth studio album, Brat.
She is performing on Saturday night on the Other Stage, 15 minutes before the West Holts stage is graced by US rapper Doechii, another artist who has exploded in popularity in the last year.
Other performers include: Prada singer Raye; US musician Brandi Carlile; Nile Rodgers and Chic; US pop star Gracie Abrams; Mercury Prize-winning jazz quintet Ezra Collective; US rapper Denzel Curry; and rising star Lola Young.
This year, the BBC will provide livestreams of the five main stages: Pyramid, Other, West Holts, Woodsies and The Park.
