How long UK heatwave will last as areas set to boil in 36C
According to the radio this morning, Britain is suffering it's 4th heatwave of the summer 🤣🤣🤣 do they know just how bonkers they sound ? What they really mean is Britain is having a typical British summer, bit sun, bit cloud, bit rain & bit wind. — 🔧🔩 Durham Steel 🔧🔩 (@PhilHannon) August 11, 2025
The hot spell would mean the fourth heatwave of the summer so far.
A combination of high pressure and a southerly airflow will see temperatures rise for much of England and Wales over the first half of the week, with temperatures reaching more than 30°C for some on Monday and likely peaking towards the mid-30s in London on Tuesday.
And the Met Office says: "Met Office heatwave criteria, where a specific threshold must be exceeded for three consecutive days, are likely to be reached by Wednesday for much of southern and central England."
GFS weather model maps show temperatures could rise to 31C in southern England at around 6pm today.
Recommended reading:
London is expected to hit 30C, with the Midlands rising as high as 29C and the north of England hitting 26C.
Tuesday's temperature maps show the mercury peaking at 36C with the warmest area again being the southeast.
Highs of 31C to 33C could come quite widely across southern and central England as well as Wales. Parts of Scotland could hit 26C, and Northern Ireland can expect 24C.

Warnings issued for thunderstorms and high temperatures as heatwave continues
Weather warnings have been issued for thunderstorms and heat alerts extended as the fourth heatwave of the summer continues. The Met Office has issued a yellow thunderstorm warning covering northern Scotland until 10pm on Thursday. Flood alerts have also been issued for Scotland. It comes as heat health alerts were extended into next week for much of England. The UK Health Security Agency said yellow warnings will now be in place for Yorkshire and Humber, the East and West Midlands, London and the South East, South West and East of England until 6pm on August 18. The Scottish Environment Protection Agency said heavy thundery showers or rain may affect the region on Thursday, with a risk of significant localised flooding effects from surface water and smaller rivers. Heavy rain and thunder hit London and Kent on Wednesday afternoon. But officials have said England is suffering from 'nationally significant' water shortfalls. The national drought group – which includes the Met Office, regulators, government, water companies and other organisations – has met as five areas of the country remain in drought, with six more in prolonged dry weather status. On Thursday, there will be residual showers and isolated thunderstorms across the South East, gradually clearing, and lightning, hail and heavy rain drifting northwards from Scotland into the Northern Isles. Paul Gundersen, chief meteorologist at the Met Office, said: 'Some areas will continue to experience their fourth heatwave of the summer so far, with Thursday remaining warm or very warm for many, though cooler near coasts. 'Temperatures could still reach 30C in eastern England, though many areas will be a few degrees cooler than earlier in the week.' Northern England will have patchy rain and cloud on Friday while southern England will enjoy sunshine and temperatures of up to 31C. The weekend should be dry and sunny for most parts of the UK, climbing to 30C on Saturday and 29C on Sunday in south-west England.

Met Office tells Brits in 38 areas to prepare 'emergency' kit with three items
Met Office weather forecasters have said thunderstorms could create intense flooding over a two day period in some parts of the UK this week, and Brits ought to be prepared The Met Office says Brits living in dozens of regions might want to consider preparing an "emergency" kit with three items as thunderstorms explode across the UK. Extreme heat has baked the ground across the country over the last few days, sending the mercury to the 30C range and igniting the country's fourth heatwave. Weather maps show the heat receding from the hottest areas from today, with the next few days to bring more manageable temperatures for most Brits. While the change will come with some relief, the hotter weather will usher in a much wetter climate, with thunderstorms set to dramatically raise the flooding risk in a matter of hours, the Met Office has warned. READ MORE: 'I moved from America to the UK and gardening is so different in Britain' The agency has issued two yellow warnings for thunderstorms this week, with the first having activated at 2pm and set to continue until midnight tonight. A second activates almost immediately after at 12am on Thursday and continues for another 10 hours until 10pm that evening. The twin alerts state that Brits might want to prepare for potential flooding as well as power cuts, with fast flowing water potentially cutting off some communities. The conditions pose a "danger to life". The Met Office has issued advice telling people living in the 38 affected areas to consider preparing a "flood plan and an emergency flood kit". The agency states vital items in the kit include torches, batteries, and a mobile phone power pack. The advice states: "Consider if your location is at risk of flash flooding. If so, consider preparing a flood plan and an emergency flood kit. People cope better with power cuts when they have prepared for them in advance. It's easy to do; consider gathering torches and batteries, a mobile phone power pack and other essential items." People should consider the advice if they live in the following affected areas: Central, Tayside & Fife Angus Clackmannanshire Dundee Falkirk Fife Perth and Kinross Stirling Grampian Aberdeen Aberdeenshire Moray Highlands & Eilean Siar Na h-Eileanan Siar Highland Northern Ireland County Antrim County Armagh County Down County Fermanagh County Londonderry County Tyrone Orkney & Shetland Orkney Islands Shetland Islands SW Scotland, Lothian Borders Dumfries and Galloway East Lothian Edinburgh Midlothian Council Scottish Borders West Lothian Strathclyde Argyll and Bute East Ayrshire East Dunbartonshire East Renfrewshire Glasgow Inverclyde North Ayrshire North Lanarkshire Renfrewshire South Ayrshire South Lanarkshire West Dunbartonshire While the warnings conclude on Thursday, the Met Office's long-range forecast, which covers August 18 to 27, warns that "heavy and thundery" showers could roll across the country again next week. The forecast states: "High pressure will be dominant across much of the UK at the start of this period. This will bring a good deal of fine and dry weather with spells of sunshine for many. Any showers will probably be confined to the southwest of the UK but could be heavy and thundery. Temperatures are likely to be well above normal, especially in the south."

People urged to put bowl of water on windowsill as heatwave hits Wales
People urged to put bowl of water on windowsill as heatwave hits Wales The Met Office has said the UK is set to be hit by a heatwave this week - but there is a cheap and easy way to keep your home cool as temperatures soar As the weather heats up once more, households are being advised to place a bowl of water on their windowsill to help keep their homes cool. The Met Office has predicted another heatwave will be hitting Wales this weekend, spanning from Friday to Tuesday. As warm temperatures are already setting in the heatwave itself is expected to kick off on Friday, August 15. The mercury is expected to climb into the upper 20s, and even lower 30s, particularly in the southeast where temperatures could reach 33°C. The Met Office predicts that Saturday appears set to be the hottest day in this time period with places like Monmouth, Newport, and Chepstow potentially reaching that 33°C mark For those staying indoors experts suggest a simple trick to reduce indoor heat using just a bowl of water. For our free daily briefing on the biggest issues facing the nation sign up to the Wales Matters newsletter here . For those without access to costly air conditioning units an affordable and effective alternative is to strategically place bowls of water around the home. Positioning a bowl of water on your windowsill or bedside table can aid in cooling your room through a process known as evaporative cooling. Article continues below In essence as water evaporates it enters the air and lowers the air temperature. This principle mirrors how evaporative air conditioning units function, adding moisture to the air to cool it down, reports the Express. Appropedia advises: "Water can be used to cool a room when you don't have air conditioning or want to save electricity. Evaporation is the best method and these methods are often referred to as a 'swamp cooler.' "Find a few round bowls such as fishbowls. They should be medium to large in size. "Fill with water. Place the bowls under a window. Every time the window is open the breeze will flow over the bowls of water and help to cool the air in the room. "This method can also be used in large containers outdoors provided you don't live where mosquitoes are a health problem." For enhanced cooling effects place ice cubes in a water-filled bowl and direct a fan towards it. Article continues below As the ice dissolves the chilled air will circulate throughout the room, providing relief from the heat.
