What is a heat dome as UK roasted by 34C heat this week
What is a 'heat dome' and what causes it?
The term "heat dome" is used to describe conditions that are not too dissimilar to a pizza oven, according to Sky News.
This is caused when an area of high pressure lingers over a region for days or weeks.
The pressure traps the hot air like the dome of a pizza oven, baking the air and surface underneath.
As the ground parches, it begins to absorb more of the heat, making conditions much worse.
Is the heat dome effect coming to the UK this week?
A heat dome is currently sitting above Europe at the moment, with the UK being at the cusp of its reach.
This means the UK is being impacted by the heat dome effect in much the same way as countries like Greece, which are basking in 40C weather, are.
Which areas are covered by the heat-health alert in England this week?
Several regions across England are covered by the heat-health alert issued by the Met Office and UKHSA.
These are the following places covered by the Amber Alert, which has been in place since Thursday and Friday.
West Midlands
Yorkshire and the Humber regions
East Midlands
South East
South West
London
East of England

Discussing the heatwave, Dr Agostinho Sousa, Head of Extreme Events and Health Protection at UKHSA, said: "The current spell of hot weather is forecast to continue until the middle of this week, with temperatures above 30°C likely in most regions of England.
"We are reminding everyone to take sensible precautions while enjoying the sun.
"Remember that it is very important to check on friends, family and neighbours who are more vulnerable, as the temperatures we are likely to see over the next few days can result in serious health outcomes across the population, especially for older adults or those with pre-existing health conditions."

UK records hottest day of year so far - as 40C highs close schools in Europe
The UK has recorded its hottest day of the year so far – while Europe has also faced extreme heat, and wildfires have raged in Turkey. A temperature of 34.7C (94.4F) was recorded at St James's Park in central London on Tuesday afternoon, the Met Office said, beating a high of 34.4C (93.9F) in Writtle, Essex, earlier in the day. The UK's previous warmest day of 2025 was Saturday 21 June, when 33.2C (91.8F) was recorded in Charlwood, Surrey. Much of Europe is also facing hotter-than-usual temperatures, with a high of 40C (104F) recorded in Paris. More than 1,300 schools in France were partially or fully closed on Tuesday after the country's national weather agency placed several regions under the highest red alert. The Paris region was particularly hard hit, and the Eiffel Tower's summit was closed to visitors as locals and tourists alike were warned to take care in the heat. In Italy, 17 major cities - out of a total of 27 - were experiencing a heat wave, according to the country's health ministry. At the Prague Zoo, staff are currently distributing up to 10 metric tons of ice per day to keep animals cool as temperatures in the Czech Republic reach 37C (98.6F). Numerous Spanish cities have also reported sweltering temperatures, with highs over the 40C in Madrid, Sevilla and Barcelona. Speaking in Seville on Monday, António Guterres, the UN secretary general, said: "Extreme heat is no longer a rare event - it has become the new normal." The city is forecast to roast in more the 40C heat for the next three days. Meanwhile, wildfires on Turkey's coastal provinces are raging for a second day running. 2:17 More than 50,000 people have been evacuated from their homes, including 42,000 from the western province of Izmir, where officials say strong winds have fanned the flames. Turkey's Hatay Province has also seen wildfires. A Met Office spokesperson said Tuesday was likely to mark "the peak of this current heatwave in terms of absolute temperatures we're expecting" in the UK. Colder temperatures will come in from the north overnight and into Wednesday morning, Stephen Dixon said.

UK sees hottest day of the year so far as temperatures pass 34C
The UK has had its hottest day of the year so far with temperatures exceeding 34C. The Met Office confirmed that 34.7C was recorded at at St James's Park in central London on Tuesday afternoon, beating a 34.4C reading recorded in Writtle, Essex earlier in the day. The previous warmest day in the UK in 2025 was June 21 when 33.2C was recorded in Charlwood, Surrey. It also exceeds Monday's peak temperature of 33.1C at Heathrow, which marked the hottest start to Wimbledon on record. Forecasters said temperatures could reach 34-35C in London on Tuesday before cooler conditions sweep in from the north later in the day. The hot weather marks the second heatwave for parts of the UK within the last month, with scientists warning the searing temperatures earlier in June were made 100 times more likely because of human-caused climate change. Provisional Met Office figures, released on Tuesday, show England had its warmest June on record last month, while the UK experienced its second warmest since the series began in 1884 – only surpassed by June 2023. The UK Health Security Agency (UKHSA) has amber heat health alerts in place for much of the country until Wednesday morning. A man died after getting into difficulty in water off Skegness beach in Lincolnshire at around 3.30pm on Saturday, the local RNLI Lifeguards team said in a Facebook post. In Bedfordshire, gritters have been dispatched to protect the roads and provide grip for drivers amid concerns the heat could cause the tarmac to soften, the local council said in a Facebook post. Met Office spokesman Stephen Dixon said Tuesday was likely to mark 'the peak of this current heatwave in terms of absolute temperatures we're expecting'. 'It's a continuation of recent days in the South East in particular, with those temperatures well beyond average for the time of year, in a fairly notable heatwave,' he added. However, Tuesday will also bring the start of a transition towards more average temperatures, as a cooler, wetter front over Scotland and the north of England gradually moves south-eastwards. 'It's already bringing some rain to parts of Scotland through the day today, and will gradually move southwards through the day today and overnight tonight,' Mr Dixon said. As July kicks off, forecasters said temperatures in the mid-30s are still relatively uncommon for the month in the UK, although they are becoming increasingly frequent with climate change. Conservationists and green experts have also warned of the wildfire risk as well as the impact on farmers, who face another poor harvest following one of the driest springs on record. Ben McCarthy, head of nature conservation and restoration ecology at the National Trust, said: 'With record-breaking temperatures across the country this week following the driest spring on record, our ranger and countryside teams are on high alert for fires which can cause decades of damage to habitats, decimate ecosystems and result in significant losses to our wildlife.' Tom Lancaster, Energy and Climate Intelligence Unit (ECIU) land, food and farming analyst, said: 'Crop condition remains poor following one of the driest springs on record, with the quality of key arable crops such as wheat, barley and oats well down on recent years. 'Many farmers will now be looking towards this harvest with real trepidation. 'For some, the weather in the coming weeks will determine whether they have anything worth harvesting at all.' Dr Garyfallos Konstantinoudis, research fellow at the Grantham Institute, Imperial College London, said: 'Heatwaves are silent killers. 'Unlike floods or storms, their impact can be invisible: people who die during extreme heat usually have pre-existing health conditions, and heat is rarely recorded as a contributing cause of death.' In a warning to drivers, Alice Simpson, RAC Breakdown spokeswoman, said: 'It's vital that anyone driving today carries plenty of water to stay hydrated behind the wheel and in case of a vehicle breakdown.'
