Flying ant swarms as large as rain clouds as Welsh experts advise action
Already swarms have been detected over parts of Britain that were so large, they were mistaken for shower clouds when picked up on radar this week. Near London they appeared as 'strange, flashing echoes' on Met Office radar screens.
The forecaster noted: 'Radar works by emitting electromagnetic beams that reflect off small particles like raindrops. Flying ants, being similar in size to raindrops, can also reflect these beams, creating radar signatures that resemble precipitation.
"This phenomenon, often seen during 'Flying Ant Day,' is a fascinating example of how biological activity can intersect with meteorological technology.'
It is a common misconception that flying ants appear only one day every summer. But research has revealed the insects take flight on multiple occasions during the summer, typically from mid-July to the end of August.

Queen ants and males tend to leave their nests to create their own colonies when the weather is hot and humid - typically when the temperature exceeds 25C, there is little wind and there is a chance of rain in the following days.
North Wales Wildlife Trust is warning householders to expect some inundations this year. A spokesperson said: 'Flying ants will be taking to the skies towards the end of July in a mating process which can actually last several weeks.
'The warm weather and wet conditions are likely to cause huge swarms this year - it's expected to be one of the biggest in recent memory! It's best to keep your windows and doors shut during their peak swarming time and leave them to it!"
Ants mate on the wing because it increases their chances of reproduction. The queen will then attempt to start a new nest before losing her wings.
Each nest will have a single queen, typically presiding over worker ants that can number between 5,000-15,000. Like most flies, the ants are attracted to sweet foods, so it's best to keep these covered if you don't want your house to be invaded.
Fly screens will help prevent them entering homes. In hot weather – like that forecast for later this week – keeping curtains shut during the day will help to keep them out while also maintaining cooler temperatures.
Flying ants can bite, although the bite is usually not harmful. In the UK, most of them are common black garden ants whose mandibles can't bite through human skin.
On the other hand, red ants can bite if they feel threatened – and they do have a stinger. Their bites can cause a sharp, painful sting and may lead to a mild allergic reaction. Sign up for the North Wales Live newsletter sent twice daily to your inbox
North Wales Wildlife Trust said the pesky insects may be annoying but they actually have positive environmental roles. A spokesperson added: 'Although they may be a bit of a nuisance, black ants are an important source of food for birds, and a friend to butterflies. Their tunnelling is also vital for soil health.'

Swarms of monster jellyfish invading North Wales beaches with visitors warned to get prepared
Monster jellyfish are likely to wash up on Welsh beaches in growing numbers in the coming years, a marine expert has warned. With the UK currently in the grip of a marine heatwave, warmer waters will bring larger - and more dangerous - sea creatures closer to coastlines. This summer, social media has been awash with photos of jumbo jellyfish on Gwynedd's west coast beaches. In recent weeks, giants have also begun washing up on the North Wales coast in Conwy. A few have been reported on Rhyl beach, Denbighshire. On Monday, July 7, Manchester visitor Lisa Whittaker came across several on Rhos on Sea beach. Valiantly she tried to slide one back into the water but she gave up after realising it was probably dead already. Stranded jellyfish are 95% water and they rapidly dehydrate when exposed to wind and sun. 'Never in my life have I seen one like it - and probably never again,' she marvelled. 'Impressively enormous' jellyfish have also been reported on Colwyn Bay beach. Local woman Dawn Roberts was left 'shocked' by one, saying: 'Never seen one so big in my life!' All were barrel jellyfish, a British native that are the giants of the jellyfish world. Strandings are not uncommon on Welsh beaches but, anedotally, people are reporting every bigger specimens. Certainly, feeding conditions this year have been ideal. UK waters are currently experiencing their second major heatwave off 2025, with sea surface temperatures currently well above average in the Celtic Sea, English Channel and southern North Sea. Anomalies of 1.5C-3C above the 1982-2012 average have been registered, with readings of 17C-20C recorded in the English Channel. These sea temperatures are more typical of early August in the late 20th century, said the Met Office. The Marine Biological Association, and the Centre for Environment, Fisheries, and Aquaculture Sciences, fear warming waters are putting marine ecosystems at risk. Harmful algal blooms are possible and species such as mussels, oysters and salmon could become stressed. Others, like bluefin tuna, sea bass, stingrays and jellyfish may thrive and expand their range. Frankie Hobro, director of Anglesey Sea Zoo, has long warned of this scenario, having seen some remarkable water temperature rises at the facility's sea intake pipe. 'We're now turning on our water chillers in May," she said. "Ten years ago it was in July. Not only are we starting them earlier, we're having to keep them going for longer.' She suspects barrel jellyfish are not getting larger – we are just seeing more of them. 'They are always big specimens out in deep waters,' she said. 'But as the sea warms they're venturing closer to coastlines, and so we're seeing more of these bigger jellyfish washing up.' Equally possible is a change in the way strandings are being reported. As North Wales beaches become busier, especially in warmer years, more shorelines sightings are likely. 'With more people going to the coast, and swimming in our waters, it's inevitable that more specimens will be seen,' said Frankie. Irrespective of size, barrel jellyfish are mostly harmless, capable of delivering a nettle-like sting at worst. Others are not, and Frankie is particularly alarmed by the growing numbers of Portugese man 'o war jellyfish being reported. 'This was once an occasional visitor, in late August and September,' she said. 'Any that washed up were usually teeny. Now they've become seasonal visitors, perhaps for several weeks, and we're seeing them earlier in the summer, pushed up by warmer currents and breezes from the Atlantic. 'They have long tentacles and their stings are nasty, very unpleasant. Unlike box jellyfish, the stings are unlikely to be fatal, but Portugese man 'o war are definitely the second nastiest jellyfish in the sea.' As Britain's seas warm, and become more dangerous, Frankie believes there needs to be a change in mindset among beach visitors. As well as wearing suitable attire, knowledge of marine first aid will have to improve. 'We've always been a bit blasé about swimming or paddling in the sea,' she said. 'Whereas people arriving here from overseas are more used to the dangers and come prepared. 'You can get sunburnt in the water very quickly and, with new threats emerging, my advice would be to always cover up.' If wet suits are not an option, then quick-drying UV rash vests should be a starting point, she said. Frankie also advises swim boots or socks. 'The surf zone, where jellyfish are spun around like a washing machine, is where you're most likely to get stung,' she said. 'Ankles are therefore the most vulnerable. 'Footwear is always a good idea not just because of weever fish in the sand, which can cause excruciating pain, but also to avoid things like razor clams and glass.' If you are stung – either by jellyfish or tiny weever fish – Frankie cautions against old wives tales. 'Peeing on the sting site is not a good idea and may make it worse,' she said. Instead, sting sites should be treated with vinegar – the acid quickly denatures sting cells. Lemon juice is another option. 'Always keep a couple of venegar sachets from chip shops in the car or beach bag,' she said. If bits of tentacles have attached to the skin, a credit card can be used to squeeze them off. Ice will help cool the burning sensation and anti-histamines will ease the pain. 'Jellyfish are sensitive to changes in osmotic pressure, so be careful not to touch them,' Frankie added.

The Shortfin mako, the world's fastest swimming shark, is already making itself more at home in the UK.

Met Office issue 'taps aff' warning as Scotland to hit 30 degrees
Alex Deakin, a presenter and meteorologist at the weather agency, said that the highest temperatures were likely in the northeast of Scotland – and topping 30C is 'pretty unusual and likely to cause problems to people with health issues'. 'I know people want to go 'taps aff' – but I would really advise against that,' he added. The highest temperature ever recorded in Scotland was 34.8C, at Charterhall in the Borders in 2022. Deakin said that such extremes were becoming more common as a result of climate change. READ MORE: Scottish actor who appeared in BBC River City accused of rape and assault READ MORE: Prosecutors claim accused were masked when they allegedly attacked man during murder 'Tell people in Scotland it's going to be two or three degrees warmer every year, most people will be quite happy – but it's a much bigger issue than that. 'It's not just, 'oh, the world is warming by a few degrees, so Scotland will get warmer by a couple of degrees'. No, it's more extremes. 'You will see these bigger fluctuations. As well as the higher temperatures, you're going to get heavier rain. 'A warmer atmosphere holds more rain, so the summer downpours are more intense, they're more dangerous. You get bigger hailstones and damaged crops. The winters will be wetter. 'It changes the natural environment, it changes what you can plant, what you can farm, it changes animal migration, things like that. It changes absolutely everything.' The third heatwave of the year, or just the first? Alex Deakin looks at which regions will be affected by this latest hot spell — Met Office (@metoffice) July 9, 2025 Deakin, a former BBC weather presenter, said that Scotland and the wider UK were due to see a heatwave from Thursday – though there is some uncertainty about when it will end. 'We're very confident in the forecast in the short to medium term, so we know that temperatures are going to increase steadily through this week, Thursday, Friday, Saturday, Sunday,' he said. 'It's not unusual to have uncertainty about the longer term forecast – cooler air out in the Atlantic is likely to move in early next week, but it's a question mark about whether that happens Monday, Tuesday, or Wednesday.' Deakin said that the central belt was likely to see temperatures in the high 20s, while the Moray coast especially could see highs of more than 30C. 'The winds going over the mountains, coming down the other side, that dries it out and really heats it up', Deakin explained. 'So the temperatures on that Moray coastline could easily be into the low 30s, particularly on Sunday.' Deakin said that a changing climate was seeing the poles warm faster than the equator, and the changing differential between the temperatures was impacting on the jet stream. 'Our weather is dictated by the jet stream. That's the basic fundamental of meteorology,' he said. 'The fact that the equator's hot and the poles are cold, that's what creates the jet stream in the first place. But what's happening with climate change is the poles are warming faster than the equator and so the temperature gradient across the two is actually lowering.' At the moment, he said a heatwave was due to hit Scotland because of an 'amplified' jet stream, which creates an area of high pressure over the UK. A wildfire in Arran's Glen Rosa in 2025 (Image: Police Scotland) While he said it was currently only a theory, Deakin explained that the lower temperature gradient may mean 'you'll weaken the jet stream and that allows it to wiggle more', creating more amplified jets and potentially more heatwaves. Deakin issued a warning to people to stay safe during the coming high temperatures. 'There's loads of evidence to suggest that when it is hot, there are more admissions to hospital,' he said. 'You do see an increase in fatalities. 'Even back in '76 – everyone quotes that summer and remembers it fondly because it was fantastic, but there was a big increase in hospitalisations then.' The Met Office expert added: 'It's a build up effect as well, which is why again it's not just about the numbers on any one day. It's about how long these hot spells last, because that has a knock-on effect.'

UK weather: Country set to have new heatwave - with temperatures over 30C in some areas, Met Office forecasts
Temperatures are expected to rise steadily throughout the week as the third heatwave of the summer is forecast for the UK - potentially hitting the low 30s Celsius in some areas. Forecasters say central parts of the UK could see highs between 26C and 28C (78.8F and 82.4F) from Wednesday, with the far north and west also experiencing hot temperatures - reaching the high 20s or low 30s by the end of the week. The rising temperatures come as the UK Health Security Agency (UKHSA) issued a yellow heat health alert for southern England. The alert is in effect from 10am Wednesday until 10am next Tuesday and covers regions including London, the East and West Midlands, East Anglia, the South East, and the South West. A Met Office spokesperson said the entire country was in for a noticeable midweek rise in temperatures, with many areas enjoying dry, sunny weather. "While the North West may remain unsettled, elsewhere it will feel increasingly warm, even hot in places, particularly across southern and eastern regions," they said. Wednesday is forecast to be mostly dry with sunny spells, although patchy rain and drizzle may linger in northwest Scotland and northern parts of Northern Ireland. Temperatures are expected to climb significantly compared to Tuesday, with much of England and eastern Wales reaching 24C to 26C. The South West could see the highest temperatures, with peaks around 28C. Eastern Scotland and Northern Ireland will also warm up, though lingering cloud cover may limit the daytime heat there. Met Office meteorologist Aidan McGivern said: "We'll see sunny skies in the south and east early on Wednesday, but much of the UK will start cloudy. By the afternoon, most areas will be dry, and temperatures will continue rising through the week. Even the north will feel warmer as cloud cover breaks and weather fronts move further away." By Thursday and Friday, temperatures are expected to stabilise across eastern Wales and much of central, southern, and eastern England. The North and West may experience the most dramatic warmth compared to seasonal averages. "It's not actually the South East where we'll see the highest temperatures," McGivern said. "The biggest anomalies relative to the norm will be in the far north and west of the UK, where highs in the upper 20s to low 30s are likely. So yes, many places will feel increasingly warm, even hot, heading into the weekend." This comes after the UK recorded its hottest day of the year on 1 July, when temperatures hit 34.7C in London's St James's Park. Provisional data from the Met Office revealed June was England's warmest on record. Experts have said previous "extreme heat events" have been the result of climate change. Met Office climate scientist Dr Amy Doherty recently said: "While we've not conducted formal climate attribution studies into June 2025's two heatwaves, past studies have shown it is virtually certain that human influence has increased the occurrence and intensity of extreme heat events such as this. "Numerous climate attribution studies have shown that human influence increased the chance that specific extreme heat events would occur, such as the summer of 2018 and July 2022." An official heatwave is declared when a location records a specific threshold temperature for three consecutive days-typically between 25C and 28C, depending on the region.
