The UK is set to be even hotter tomorrow as temperatures could soar to a sweltering 35C with an amber health alert extended across England.
Forecasters issued the alert which will cover London, the East Midlands, the South East, the South West and the East of England, and is set to remain in place until 6pm tomorrow.
The Met Office say a rare amber alert is only deployed when they think there is a 'potential risk to life and property' and marks the second time it has been issued in two weeks.
The UK Health Security Agency (UKHSA) has also activated a five-day alert due to concerns that there could be 'a rise in deaths, particularly among those ages 65 and over or with health conditions'.
Images from today showed packed out beaches and rammed swimming pools of people frolicking in the water, while tennis fans braved the red-hot weather to face the scorching conditions on day one of Wimbledon.
Temperatures in SW19 were today so hot that an elderly member of the crowd on Centre Court fainted during Carlos Alcaraz’s first-round tussle with Fabio Fognini.

Greg Dewhurst, a meteorologist at the Met Office, told MailOnline that the hottest temperatures would hit the southeast of England tomorrow, particularly in London.
And a map issued by the forecasters shows that they expect temperatures could hit a sizzling 35C.

Tomorrow's warning comes as Europe continued to be blasted by record temperature highs with a deadly 'heat dome' scorching the continent.

George Sandhu, Deputy Superintendent at Well Pharmacy, is urging elderly and vulnerable Brits to consider staying in the shade or indoors during the hottest hours of the day.
He said: 'While many people will be out enjoying the warm weather, elderly and vulnerable Brits who are at greater risk because they can have less control over their exposure to the sun.

Jennie added: 'We're want to attended for the next three days so we will be queuing up every day.
'We're from Florida, so the heat is fine for us, but we were not expecting this in England. We have our umbrellas for shade and plenty booze and card games. We've already had three bottles of bubbly so far this morning!'
Elsewhere in the UK, footage from Highland and Moray, in the Scottish Highlands, showed wildfires and smoke obscuring the landscape as fire crews battle blaze that has been burning since Saturday morning.
The blazes, which have been whipped up by strong winds and dry weather, have stretched several miles in places - and even sparked warnings for communities as far away as Forres and Elgin to keep windows shut.

Tennis fans were given a shock this morning after being told to stay away from Wimbledon as it is already 'at capacity'.
Earl's Court tube station, a popular changeover point en route to Wimbledon, was packed with tennis fans who had flown in from all over the world.
But an announcement over the PA system quickly put a dampener on the excitement after it was revealed the grounds were already 'at capacity' before 9am.
Those who had opted for a slightly later lie-in faced disappointment then when they were told that non-ticket holders risk not getting in, or at best 'several hours' waiting in the queue with temperatures soaring for the rest of the day.
An update from Wimbledon's official website on Monday read: 'Please be aware that the Queue for Day 1 - Monday 30th June - is very busy and to avoid disappointment we strongly advise you not to travel to the Grounds today.'
On Sunday, firefighters mobilised in several European nations to tackle blazes as southern Europeans sought shelter from punishing temperatures of a heatwave that is set to intensify in the coming days.
Fires broke out in France and Turkey Sunday, with other countries already on alert.
Authorities from Spain to Portugal, Italy and France urged people to seek shelter and protect the most vulnerable from the summer's first major heatwave.
Ambulances stood on standby near tourist hotspots as experts warned that such heatwaves, intensified by climate change, would become more frequent.
In Turkey, forest fires broke out Sunday afternoon in the western Izmir province, fed by strong winds, local media reported.
In France, meanwhile, wildfires broke out in the Corbieres area of Aude in the southwest, where temperatures topped 40C, forcing the evacuation of a campsite and abbey as a precaution.
The country's weather service Meteo France put a record 84 out of its 101 regional departments on an orange heatwave alert - the second-highest - for Monday.

In Italy, 21 cities were on high alert for extreme heat, including Milan, Naples, Venice, Florence and Rome.
'We were supposed to be visiting the Colosseum, but my mum nearly fainted,' said British tourist Anna Becker, who had travelled to Rome from a 'muggy, miserable' Verona.
Hospital emergency departments across Italy have reported an uptick in heatstroke cases, according to Mario Guarino, vice president of the Italian Society of Emergency Medicine.
'We've seen around a 10 percent increase, mainly in cities that not only have very high temperatures but also a higher humidity rate. It is mainly elderly people, cancer patients or homeless people, presenting with dehydration, heat stroke, fatigue,' he said.
In Venice, authorities offered free guided tours for people over 75s in air-conditioned museums and public buildings.
Bologna has set up seven 'climate shelters' with air conditioning and drinking water, Florence has called on doctors to flag up the lonely and vulnerable, Ancona is delivering dehumidifiers to the needy, and Rome has offered free access to city swimming pools for those over 70.

BREAKING NEWS
Deadly 'heat dome' to sizzle Britain: 47C weather phenomenon hitting Europe will also bake the UK
In France, experts warned that the heat was also severely impacting biodiversity.
'With this stifling heat, the temperature can exceed 40 degrees in some nests,' said Allain Bougrain-Dubourg, president of the League for the Protection of Birds.
'We are taking in birds in difficulty everywhere; our seven care centres are saturated,' he said.
It is also attracting invasive species, which are thriving in the more tropical climes.
The alert, which covered London, the East Midlands, South East, South West and East of England, will last until 6pm on Tuesday.
The UK Health Security Agency (UKHSA) also issued a yellow alert for Yorkshire and Humber and the West Midlands for the same time period, with the agency warning of significant impacts across health and social care services.
An amber alert was previously issued for all regions in England on June 19, the first time it had been used since September 2023.
An official heatwave is recorded when areas reach a certain temperature for three consecutive days, with thresholds varying from 25C to 28C in different parts of the UK.
The intense heat is set to continue across Europe tomorrow with temperatures reaching 37C in France

Europeans warned to stay indoors as continent goes on high alert for 47C heat and forest fires
London Fire Brigade assistant commissioner Thomas Goodall said: 'London is already facing its second heatwave of the year and we know that people will be looking forward to getting outside to enjoy the wonderful weather.
'But the high temperatures and low rainfall in recent months means the current risk of wildfires is severe.
'So far this year, firefighters have responded to around 14 wildfires in the capital.
'There have also been countless call outs to smaller fires involving grass, trees and in other outdoor spaces, as well as in people's gardens.
'During this latest heatwave, it is important everyone acts responsibly to prevent fires from occurring.
'As the weather has been so dry, it only takes a few sparks to lead to a fire spreading rapidly.
'In London, this is can be dangerous because so many of our green spaces lie close to homes and other properties.'
There will be a 'marked difference' in north-western parts of the UK however, with cloud and heavy rain in parts of Northern Ireland and Scotland, where temperatures will stay in the mid to high teens, Mr Lenhert said.
The hottest ever July 1 on record was in 2015, when the temperature hit 36.7C.
