Another heatwave could be on the way as weekend temperatures forecast to hit 30C
More changeable weather is expected this week with some showers, before temperatures are set to rise at the weekend hitting 29C on Saturday, then potentially 30C on Sunday and 31C on Monday, the Met Office said.
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.
Oli Claydon, spokesman for the Met Office, said this week more changeable weather is on the way compared to the previous few weeks.

Glastonbury-goers can expect a mixed bag of sunshine and rain this week.
More than 200,000 people are expected to descend on the fields of Pilton, with ticket-holders advised to prepare for mainly warm weather, but to also bring waterproofs to the five-day event.
Mr Claydon said: 'Wednesday will be warmer, though an increasing risk of showers and thunderstorms, with a maximum of 28C in the South East.
'Through the day we will have some showers moving into south-western parts, with a thunderstorm risk in the South East.
'As we go into Thursday, there will be heavy showers potentially in the east, but there will be some clear spells in there as well, with a maximum of 27C.
'Not everywhere will see the showers and there will be some dry spells around as well.
'There will be more persistent rain around the north west of Scotland on Thursday evening.
'Friday will see a maximum of 27C again as the high, the showers will clear away to the north east, with local drizzle in parts of the South West and Wales through the day.
'When we go into the weekend is when we start to see the temperatures get higher, with 29C in the South East.
'On Sunday there could be some cloud and showers about in the north and North West, that will ease through the day then it will be dry and clear with good sunny spells, potentially 30C on Sunday in the South East.'
Monday could see 30C or even 31C but the certainty around that is not very high yet, Mr Claydon added.
It comes after a provisional high of 33.2C was recorded by the weather service on June 21 in Charlwood, Surrey, making it the warmest day so far of 2025.
Last week the Met office said 'many places' in England and 'one or two areas' in Wales, including Cardiff, entered a heatwave on June 20.
A short-lived localised heatwave is possible in the South East of England as temperatures rise this weekend, Mr Claydon said.
He said: 'It's a little bit uncertain, potentially we could remain in the 30s in the far South East of England, and it's quite a long way ahead, there is potential there and if it did reach into the 30s in the South East we could be looking at a short-lived localised heatwave.
'When we had the warm spell last week it was much more widespread, we're not likely to see that.'
Temperatures are looking to fall next week, the forecaster said.
So far, June's average daytime temperatures have been 19.2C, slightly above the average of 17.68C, according to the Met Office.

The deadly hidden dangers of heatwaves - and how to keep yourself safe
Nearly 600 deaths are expected across England and Wales due to the current heatwave, scientists have warned. Researchers from the London School of Hygiene and Tropical Medicine and Imperial College London estimate around 570 excess deaths between Thursday and Sunday, based on historic mortality data. The new research follows a World Weather Attribution (WWA) research group study which found the heatwave has been made about 100 times more likely and 2-4C hotter due to climate change. Temperatures could reach 30C on Saturday, following highs of 29C in Coningsby, Lincolnshire, on Friday, according to the Met Office. It comes as a second amber heat health alert in two weeks came into force on Friday. The alert, which covers London, the East Midlands, South East, South West and East of England, will last until 6pm on Tuesday. Here, The Independent looks at how you can keep yourself safe during a heatwave: Prevent dehydration The government advises staying hydrated during hot weather by drinking fluids regularly throughout the day, particularly if you are active. Water, diluted squash and lower-fat milks are recommended. While fruit juice, smoothies and soft drinks can seem refreshing, they often contain high levels of sugar, which may contribute to dehydration. It's best to limit how much of these you consume and opt for diet, sugar-free or no-added-sugar alternatives instead. If you're heading out, take a refillable bottle of water with you, and carry extra if travelling by car or public transport. Alcohol can dehydrate the body, so choosing alcohol-free drinks or alternating alcoholic drinks with water is advised. Protect yourself from the sun The sun in the UK is strong enough to cause sunburn, with children especially vulnerable to skin damage. To reduce your risk, follow these sun safety measures: Stay in the shade between 11am and 3pm, when the sun is at its strongest Wear loose, light-coloured clothing made from tightly woven fabric, such as long-sleeved shirts, trousers or long skirts Protect your head, neck, face and ears with a wide-brimmed hat Use sunglasses to shield your eyes from the sun Apply sunscreen generously and top it up regularly, especially after swimming or using a towel. The NHS recommends using sunscreen with a sun protection factor (SPF) of at least 30 and a UVA rating of four or five stars. How to keep your home cool Homes can become uncomfortably warm during hot weather, especially at night when trying to sleep. To keep indoor temperatures down, consider the following steps: Keep blinds and curtains closed on windows that face direct sunlight during the day If your home has external shutters or shades, keep them closed too Try to sleep or rest in the coolest part of the house When it's cooler outside than indoors, typically during the night, open windows if it is safe, and create a cross-breeze to help air circulate Use electric fans if the indoor temperature is below 35C, but avoid directing airflow straight at your body, as this can contribute to dehydration Make sure heating systems are switched off Turn off any lights or electronic devices not being used, as they can generate extra heat If the temperature outside is cooler, especially in shaded areas, consider spending time outdoors Public spaces such as places of worship, libraries or supermarkets may be cooler than your home. If they are nearby, visiting one can offer a helpful break from the heat. Heat exhaustion happens when the body gets too hot and struggles to cool down. It's not usually serious if you cool down within 30 minutes, but if untreated, it can develop into heatstroke, according to the NHS. Signs of heat exhaustion include: Tiredness or weakness Dizziness or feeling faint Headache Muscle cramps Nausea or vomiting Heavy sweating Strong thirst Heatstroke is more serious and occurs when the body's temperature rises to dangerous levels and can no longer cool itself. Symptoms include: Confusion or disorientation Loss of coordination Rapid heartbeat Fast breathing or shortness of breath Hot, dry skin (not sweating) Seizures Heatstroke is a medical emergency. Call 999 immediately and try to cool the person down while waiting for help. Who is most at risk during hot weather? While anyone can feel unwell in the heat, some people are more vulnerable. These include:

Why 10-second sirens will sound on our phones this year
The UK government will test the emergency siren system for the last time in 2025 The government's emergency alert siren, designed to warn the public of severe emergencies such as flooding, fire and other extreme weather, is set for another test this year. The system, which was first launched in 2023, will trigger a 10-second siren emitted from millions of mobile phones, alerting the public to emergencies affecting their areas. According to the Independent, this should be the final test of 2025. Mobile phone users affected by the test will receive an alert on their home screen, with their devices also vibrating, reading out the alert and sounding off a series of siren beeps for up to 10 seconds, even if it's in silent mode. Users won't be able to use any other functions on their phone until they've acknowledged the message. Phones that are switched off or in flight mode won't be affected, and individuals can choose to opt out of the testing scheme. It's expected that about 90% of mobile phones in any test area will be affected via 4G and 5G networks. For those who don't have compatible devices, they can still be alerted to emergencies through other avenues. While the date of the test hasn't been confirmed yet, this is believed to be the final test of 2025. After which, the system will be tested every two years. In January, an urgent red warning siren blared across various counties due to the extreme winds brought by Storm Éowyn, alerting residents of a 'danger to life'. The text cautioned: "A RED warning for wind has been issued. Extremely strong winds associated with Storm Éowyn are expected to cause significant disruption from 10am on Friday 24 January 2025. "Strong winds can present a danger to life, causing flying debris, falling trees and large waves around coastal areas. Stay indoors if you can. It is unsafe to drive in these conditions. Avoid coastal areas. "The storm may damage infrastructure causing power cuts and disruption to mobile phone coverage. Consider gathering torches, batteries, a mobile phone power pack and other essential items you already have at home. "Stay up to date with the weather forecast and follow advice from emergency services, network operators and local authorities. Search online for and Met Office warnings and advice." These critical alerts are dispatched solely by emergency services, government entities, and organisations tasked with public safety during emergencies. Recipients generally receive these alerts in English, however, those in Wales may get Welsh versions of the message. The government has rolled out a new system sending emergency alerts based on your current location, with the stark advice to "stop what you're doing and follow the instructions" should you receive one. Yet, drivers have been warned: "Do not read or respond to an emergency alert while driving or riding." Instead, they are instructed to: "Find somewhere safe and legal to stop before reading the message. If there's nowhere safe and legal to stop, and nobody else is in the vehicle to read the alert, you can listen to news on live radio to find out about the emergency."
