UK weather: Britons brace for record temperatures again - as hot spell yet to peak

The hottest day of the year could be recorded for the second day in a row as temperatures are set to rise further today, the Met Office has said.
After a peak of 32.2C (89.9F) was reached yesterday at Kew Gardens and Heathrow Airport in west London - making it the hottest day of the year so far - a new high of 33C (91.4F) is forecast for Friday.
It comes as an amber heat alert was issued for all regions of England, with the heat health warnings by the UK Health Security Agency's (UKHSA) remaining in place until 9am on Monday.
The amber alert indicates "significant impacts are likely" across health and social care services, and warns there could be "a rise in deaths" among people with pre-existing health conditions and those aged over 65.
The Met Office said today's temperatures are expected to reach the low 30s and potentially 33C, while a number of areas are forecast to pass the heatwave criteria by the afternoon.
A heatwave is officially declared when temperatures exceed a certain level for three days in a row.
Thresholds vary from 25C to 28C (77F to 82F) across the UK.
Met Office forecaster Dan Stroud said: "We're expecting the hot and dry conditions to continue, it does turn a little bit hazier in the west during the course of Friday, we're still expecting temperatures to reach the low 30s, 31C, 32C fairly widely, maybe seeing 33C."
Although clouds are expected to move in from the west on Saturday, bringing the possibility of thundery showers in North Wales and northwest England, temperatures could rise further.
Peak on Saturday
Sky News' weather producer Joanna Robinson said: "Saturday looks to bring the peak of the heat, with large parts of England seeing above 30C.
"Somewhere in eastern England could see 34C (93F). If that occurs, it would be only the 6th time the UK has reached 34C in June since 1961."
She went on: "Temperatures won't be as high further north and west on Saturday, but humidity levels will be higher making it still feel hot and uncomfortable.
"There'll be little relief at night, with some areas perhaps experiencing a tropical night - where temperatures don't fall below 20C.
"Sunday will bring cooler and fresher conditions from the west, but south-east England will stay very warm.
"Throughout there'll be a good deal of fine weather, but there'll be an increasing chance of thunderstorms this weekend."

Strathclyde is set to sizzle this weekend with highs of 27C

The Met Office's UK temperature map shows the country's major cities sitting in the mid-20s on Friday (June 20). Strathclyde is set for a scorcher today with warm air from Africa reportedly bringing Scotland's hottest weather of the year. The area could see highs of 25C later this afternoon with the UV index at high between 11am and 2pm and temperatures reaching 24C by midday. ‌ The Met Office's UK temperature map shows the country's major cities sitting in the mid-20s on Friday (June 20). ‌ The forecast is largely dry with long bright or sunny spells and becoming very warm or hot. Tonight will be a very mild, uncomfortable night for sleeping. There will be some evening sunshine then clear periods, and while the odd shower can't be ruled out, most places will remain dry. Minimum temperature will be 17C. The hot weather is set to continue into the weekend becoming very warm again with some sunny spells. A few sharp showers showers may develop through the day, possibly heavy and thundery with a maximum temperature of 27C predicted in some areas. A Met Office spokesperson said: "The nights will also be quite warm, with the possibility of temperatures not falling below 20°C in some areas, making it hard to sleep. This is what we term a 'tropical night'. ‌ 'Temperatures will ease from the west on Sunday as fresher air arrives from the Atlantic." *Don't miss the latest headlines from around Lanarkshire.

UK heatwave: Wildfire, health and drought warnings explained in five key maps

The UK could set a new high for the warmest day of the year for the second day in a row, with forecasters predicting temperatures could reach up to 33C. Thursday saw the mercury hit 32.2C in Kew, west London – the hottest day of 2025 so far – as the country sweltered under an amber heat-health alert. The warning, issued by the UK Health Security Agency (UKHSA) for the first time since September 2023, covers all regions of England and remains in place until 9am on Monday. It warns 'significant impacts are likely' across health and social care services because of high temperatures, including a rise in deaths, particularly among those aged 65 and over or people with health conditions. Meanwhile, temperatures are forecast to reach the low 30s and could potentially hit 33C on Friday, the Met Office said. By Friday afternoon, several areas are expected to have passed the heatwave criteria, Met Office weather forecaster Dan Stroud 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. Mr Stroud said: 'We're expecting the hot and dry conditions to continue, it does turn a little bit hazier in the west during the course of Friday, we're still expecting temperatures to reach the low 30s, 31C, 32C fairly widely, maybe seeing 33C.' It comes after a warning has been issued as firefighters have responded to more than 500 wildfires across England and Wales this year so far. As of Thursday, 564 wildfire incidents have been responded to by English and Welsh fire and rescue services so far this year, which is a 717 per cent increase on the same period in 2024, and more than double the number seen in 2022 which went on to be the worst year on record for wildfires, the National Fire Chiefs Council (NFCC) said. Public safety advice issued by the NFCC includes avoiding the use of disposable barbecues in open countryside, parks, and moorland areas and not discarding cigarettes, matches, or glass bottles, as they can ignite dry vegetation. With drier conditions during this time of year meaning that fires can burn into peat, and can burn for longer, it is likely some fires will take a number of days, rather than hours, to extinguish, causing more damage and placing further pressure on fire and rescue services, the NFCC added. Increasing amounts of cloud will move in from the west on Saturday, with a chance of showers, some which could be thundery in North Wales and north-west England, while eastern areas will see another dry and hot day, he added. Temperatures will be in the low 30s, and probably be the peak of the hot spell on Saturday, as 34C is possible, still below the June record of 35.6C in 1976. Sunday will be another very warm day in the south and east probably in the late 20s, elsewhere it will be cooler, with temperatures in the mid 20s, Mr Stroud said. Earlier this month, the Environment Agency (EA) said Yorkshire moved from 'prolonged dry weather' to ' drought ' status. This means the county is facing a shortage of water after a prolonged period of low rainfall. Yorkshire Water said the drought status does not immediately change the situation for customers but water restrictions – such as a hose pipe ban – are possible this summer unless the county sees 'significant rainfall' in the coming months. It follows the declaration of drought for the north west of England at the end of May, which covers Greater Manchester, Merseyside and Cheshire, and Cumbria and Lancashire. Meanwhile, a number of charities have issued warnings about the potential risks of hotter weather. St John Ambulance urged the public to familiarise themselves with the signs of heat exhaustion and heatstroke and to learn how to respond. The British Heart Foundation is encouraging people with heart conditions to take precautions such as staying cool and keeping hydrated to minimise potential health risks during a heatwave, saying the heat can put extra strain on the heart. Age UK urged people to check in on older relatives, friends, and neighbours to see if they need anything and to make sure they are not feeling overwhelmed by the excessive heat. Dementia UK issued advice and tips on how to support a loved one with dementia in the heat, including keeping hydrated; staying cool with appropriate clothing; keeping the person out of the heat; cooling the person down by avoiding hot drinks, alcohol and caffeine; and keeping the home environment cool.

What you should be doing to your garden during this heatwave

The UK is currently experiencing a heatwave. But how do you look after your outside space in the heat? And how how can gardeners minimise the damage caused by high temperatures? 'It's about risk management,' says Nick Turrell, RHS horticultural advisor. 'No-one's going to suddenly change all their plants, getting plants with silver leaves etc. 'Some plants are more susceptible than others, and I would say the top five are hydrangea, which likes slightly cooler temperatures and plenty of water, Japanese maples, which have thin leaves and lose moisture, fuchsia, astilbes and roses, which are hungry and thirsty. They catch gardeners out.' Plants likely to cope better include lavender, rosemary, sedum and other succulents, he says. But what else can we do? 1. Water wisely 'Water in the morning because that's when the plants are going to be needing it during the day,' Turrell advises. 'Don't spray the leaves or water on the top of the leaves, get it underneath to the roots and use a watering can, not a hose, because if you've a hose, you're more likely to liberally spray it around, which means you get a sprinkling on the surface which just evaporates. Get the nozzle of the watering can right in at the roots.' Melissa Quinney at Cabin Master, advises: 'During hosepipe bans or dry spells, greywater (from baths or washing up, provided it's free from harsh chemicals) can be reused to water ornamental plants.' 'It's best to water less frequently but more thoroughly, soaking the rootball properly,' suggests Charles Carr, head of wholesale nurseries at Hillier Nurseries and Garden Centres. Water plants in the area where the roots are, suggests Nick Hamilton, son of the late Gardeners' World icon Geoff Hamilton and owner of Barnsdale Gardens in Rutland. 'Some plants will require more than others, so when considering whether a plant needs water then my view is that if you're not sure, don't water. Don't worry if a plant begins to wilt from under-watering, because if you then apply water, within an hour or so you would never know it was wilting.' Give watering priority to anything which has been planted within the last 12 months, and particularly newly planted trees, Turrell adds. 2. Mulch the surface 'To lock in moisture and protect plants during a hot spell, cover the top of container plants with a mulch such as gravel, bark or a good quality compost. You should also mulch garden beds to help bedding plants retain moisture and give them a nutrient boost,' suggests Dobbies ' plant buyer, Nigel Lawton. 'Add organic mulch such as wood chippings, garden compost or leaf mould to beds to save water and improve moisture retention. A thick layer of mulch will block sunlight, insulating the soil and reducing the amount of water evaporating from the garden,' Carr adds. 'I think a good shredder is a very worthwhile investment as old flower stems, twigs and vegetable material, such as brassica stems, can be shredded down, composted and used as an excellent mulch,' suggests Hamilton. 3. Don't buy new plants If the hot weather is forecast for a few weeks, there's no point planting new plants because you'll just be putting stress on them and on the watering system, Turrell advises. 'Anything that has been established for more than two years should be OK because it already has its roots down deep enough to cope with unusual circumstances. 'But the plants will tell you if they need a drink, when they start wilting or the leaves start to curl up around the edges,' he explains. 4. Take hanging baskets down The compost in hanging baskets can evaporate so quickly that it's best to take them down during a heatwave and put them in the shade where they won't lose water so rapidly, says Turrell. 5. Pick vegetables which are likely to bolt Lettuces are prone to running to seed in hot weather, so pick them young and keep them in the fridge, or shade them with netting to keep the heat of the sun at bay, says Turrell. 6. Find shade 'For those especially vulnerable during extreme heat, temporary shade structures using old bedsheets, garden furniture, or shade cloths can make all the difference,' says Quinney. 7. Huddle patio pots Put patio pots in the shade together to create a microclimate and reduce evaporation, says Turrell. 8. Look after wildlife Make sure birdbaths are topped up because they will need it for drinking and bathing, and put some pebbles in water-filled pot saucers to allow insects to land and drink as well. 9. Leave your grass The grass may look like a mass of straw but it will recover when the autumn rain comes, so if you can stand it looking brown, just leave it, says Turrell. However, if it has been newly laid and hasn't yet been through a winter, you'll need to water it. 'In hot spells, it's best to hold off on applying weedkillers or fertilisers. These can be too harsh when the lawn is already under stress and may cause more harm than good,' says Peter Chaloner, managing director of garden machinery specialists Cobra. 'When grass turns yellow and brittle, it's a sign it's conserving energy due to lack of water. At this point, try to keep foot traffic to a minimum and clear away furniture or toys so the lawn has the best chance to recover undisturbed.' 10. Plant drought-tolerant species If you have spaces you feel you must fill, plug the gap with drought-tolerant species such as lavender, rosemary, salvia and sedum – but remember they will also need watering until they become established. 'Generally, succulents and silver foliage plants like lavender are the best at adapting to warmer conditions, so these are fine to be left as they are, but you should make a point to check up on your other plants throughout the summer months and adjust watering as needed,' says Lawton. 11. Improve your soil 'An excellent way to improve a light soil and increase its moisture retention capabilities is to add organic matter, which could be your own garden compost, green composts or well-rotted farmyard manure. Any one of these can be lightly forked into the surface and then added to the surface as a thickish layer to act as a mulch,' Hamilton advises. 'If you look after your soil, pretty much everything else falls into place,' says Turrell. 'If every year you mulch that soil with as much organic matter as you can, you are helping to prepare for any eventuality.' 12. Use a water butt This is another vital investment, says Hamilton, and can be fitted to trap and hold much needed rainwater – when it does finally come – from all your downpipes. 'I would also consider using the low-pressure leaking pipe that will work from a water butt. When buried just under the soil surface and laid out around the plants that require a bit more moisture, water will just gradually leak out and because it is under the soil, evaporation will be minimal.'
