There is some welcome relief ahead for those who are dreading the impending blistering weather - thunderstorms and rain are expected to bring the sweltering heatwave to a dramatic end.
Most of the UK is set to bake in the coming days with an amber weather warning already in place.
The Met Office said a heatwave is likely across much of the UK later this week, with the hottest weather expected on Saturday.
Temperatures could hit 36C, and the heat is going to make for an uncomfortable weekend. But by Monday afternoon, things are set to really change.
Some may see up to a six-hour thunderstorm, and it's going to be wet - great news for gardens across Britain as plants and grass suffer during one of the driest summers recorded.
Thames Water is set to announce a temporary hosepipe ban "in the coming weeks" due to the long-term forecast of dry weather.
But the heatwave will begin to subside early next week with highs of 27 degrees predicted.
Thunderstorms are then set to sweep over the country, with London seeing the change in conditions from 1pm.
Many that don't see storms with still get rain with it forecast to be wet for most areas.
A heat health alert was today extended for 24 hours as the Met Office issued an amber weather warning.
The alert for extreme heat across Thursday, Friday, Saturday and Sunday comes with temperatures set to soar.
It covers large parts of the UK including the East Midlands, East of England, West Midlands, South East England, North West England, South West England, Yorkshire and Humber and Wales.
It follows the first ever red warning issued last month, when temperatures in parts of the UK exceeded 40C for the first time.
The UK Health Security Agency have also issued a level-three heat-health alert to apply from Tuesday to Saturday.
The Met Office confirmed: "With high temperatures now forecast to last throughout the weekend, the UK Health Security Agency has extended the current heat health alert.
"The alert is now in place from midday Tuesday 9 August until 11pm Sunday 14 August.
"The public are urged to look out for family, friends and neighbours who may be more vulnerable during prolonged periods of hot weather – particularly elderly people who live alone and people with underlying health conditions."
There is an increased risk of water safety and fire-related incidents and a warning for those likely to visit coastal areas, lakes, rivers and other beauty spots.
The UK Health Security Agency has already issued an amber alert covering southern and central England from noon on Tuesday until 11pm on Sunday, with experts advising people to look out for those who are older or with existing health conditions, as well as young children.
Dr Agostinho Sousa, head of extreme events and health protection at the UKHSA, said: "We want everyone to enjoy the warm weather safely when it arrives but remember that heat can have a fast impact on health.
"It’s important to ensure that people who are more vulnerable – elderly people who live alone and people with underlying health conditions – are prepared for coping during the hot weather.
"The most important advice is to ensure they stay hydrated, keep cool and take steps to prevent their homes from overheating."
