Met Office reveals best time to see Northern Lights in UK this week
The stunning night sky display, also known as the aurora borealis, is typically only seen in northern latitudes, like Sweden, Norway, and northern Canada. However, the Northern Lights are more intense and frequent at the moment thanks to the solar cycle.
The Sun is currently at the peak of its 11-year cycle, with high levels of activity from the Sun increasing the chance of spectacular aurora displays until around mid-2025..

Last week, the northern hemisphere entered astronomical spring following the spring equinox. The Northern Lights are more common during an equinox due to an alignment of the Earth's magnetic field with solar wind, the charged particles that trigger geomagnetic storms and, in turn, aurora displays.
After the Met Office forecast an "enhancement in solar activity" on Sunday evening (March 23), the weather agency has said aurora sightings might be possible for northern parts of the UK again this week.
The Met Office said: "There is a continuing chance of aurora sightings at times across northern Scotland this coming week, given clear night-time skies. This is due to further possible weak coronal mass ejections glances, along with another faster stream of solar winds arriving later mid-week."
According to Met Office aurora maps, the best time to see the Northern Lights is on Tuesday evening (March 25). The aurora could be visible from around 9pm and peak at around midnight (March 26).
The Northern Lights could also be visible the following night, with the aurora forecast to peak at midnight (March 27).
The Northern Lights are caused by large explosions of activity from the Sun, which throw out huge amounts of charged particles – called solar wind – into space. Massive explosions on the Sun are known as 'coronal mass ejections', according to the Greenwich Royal Observatory.
These particles stream away from the Sun at around one million miles per hour, the Met Office says. When they are captured by the Earth's magnetic field they can collide with gas molecules in the atmosphere in an event called a geomagnetic storm. Light is emitted from these collisions at various wavelengths, forming spectacular colourful displays in the sky.
In its four-day space weather forecast, the Met Office said a "coronal hole fast wind" could arrive from March 25 onwards, bringing a chance of "minor" geomagnetic storms.

European wildfire smoke dampens UK heatwave with unusually hazy conditions
Smoke from wildfires in Southern Europe has brought hazy conditions to the UK, disrupting the current heatwave, forecasters have said. The UK experienced the fourth heatwave of the summer this week, with some areas seeing the mercury climb above 33C in the hottest places. However, the Met Office said "smoke from wildfires in Spain and Portugal, plus Saharan dust, has drifted over the UK'. This means the UK should expect "enhanced sunsets and sunrises in the coming days - deeper reds and oranges thanks to light scattering,' the forecaster added. Scientists say the phenomenon is linked to two processes known as Rayleigh scattering and Mie scattering. Rayleigh scattering, caused by tiny air molecules, normally makes the sky appear blue by scattering shorter wavelengths of light, such as violet and blue, according to the Royal Meteorological Society. But larger particles released by wildfires, such as soot and ash, trigger Mie scattering, which scatters all wavelengths more evenly and allows longer red and orange wavelengths to dominate. Met Office meteorologist Greg Dewhurst told Sky News the haze "will hang around for the next few days". The Met Office's forecast for Sunday says low clouds retreating towards the North Sea means there will be 'plenty of sunshine for most'. There will be strong winds in the South West of England, and it will remain warm along the eastern coast. Spain battled 14 major fires driven by high winds and aggravated by heat on Friday as authorities warned of "unfavourable conditions" to tackle flames that have already killed seven people and burned an area the size of London. Firefighters have been battling to put out blazes across southern Europe in one of the worst summers for wildfires in 20 years. An early two-week heatwave and southerly winds were worsening the situation in Spain, Virginia Barcones, director general of emergency services, said. Wildfires have burned more than 157,000 hectares in Spain so far this year, almost double the annual average, according to the European Union's Forest Fire Information Service. In neighbouring Portugal, meanwhile, thousands of firefighters were battling five large blazes in central and northern parts of the country, with one fire in Trancoso, some 350 km northeast of Lisbon, now raging for six days. Europe has been warming twice as fast as the global average since the 1980s, according to the EU's Copernicus Climate Change Service. The EU monitoring agency says that 2024 was the hottest year on record both globally and in Europe, which experienced its second-highest number of 'heat stress' days.

'Severe and frequent' wildfires threat sparked by multiple UK heatwaves
As Wales heats up during the fourth heatwave of this year so far, the Met Office have warned that it may not be blue skies for some as fire services deal with scorching wildfires. Wales is set to reach temperatures of up to 29C this weekend - August, 16 - in areas such as Cardiff and Monmouth, Cardigan, Chepstow, and Newport just behind. Wildfires grappling Spain and Portugal due to the rising temperature may be the reason for the lack of blue skies in your area as the smoke, plus Saharan dust, drifts across the UK, according to the Met Office. Wales has had an increase in temperature this week once again with Cardiff being the hottest city across the UK.

See our Privacy Notice Elsewhere, the South Wales Fire Service have helped tackle the major wildfire at Holt Heath, Dorset that is believed to have been deliberately started on August, 9 lasting six days. South Wales firefighters joined crews from across the UK to aid fire crews in Dorset due to "a critical lack of resources", according to Fire Brigades Union. Ben Selby, Fire Brigades Union assistant general secretary said: "Fourteen years of austerity have led to incidents such as the wildfire at Holt Health becoming national emergencies. The loss of 1 in 5 firefighter posts to cuts, with fire engines taken off the run and fire stations closed up and down the country, means that there is no resilience left. "Wildfires are intensive incidents, requiring a large number of firefighters and specialist resources. They are becoming increasingly severe and frequent as a result of the climate emergency. "The government must face this reality and ensure that the UK is equipped to face these increasing threats by providing the investment the fire and rescue service needs." As well as south Wales crews travelled from Merseyside, Greater Manchester, Leicestershire, Surrey, Lincolnshire, Hampshire and the Isle of Wight, Avon, Essex and Kent among others, to assist local emergency services.

How certain kinds of clouds can help predict the weather
Did you know that certain kinds of clouds can help predict the weather? I love answering questions about weather and science, and I got a great question from Brent. He saw some strange looking clouds and asked, "What does this?" This is a really cool picture, and you may not often see clouds that almost seem to have tentacles like these clouds do. The first thing to remember is the weather down here at Earth's surface is much different than the weather 20 thousand to more than 30 thousand feet high! That high up the temperatures are different, the humidity is different and the winds are different. This obviously leads to different weather outcomes, like the clouds. So, the generic classification is that Brent sent us a picture of cirrus clouds. Cirrus clouds are those thin, wispy clouds. They are composed of ice crystals and are usually the sign of an approaching warm front. These cirrus clouds become a little thicker as the warm front gets closer. Obviously, the picture that Brent sent us shows thinner clouds, so the actual front is still a ways off. You will notice that these clouds sort of look like jellyfish because of the streaks behind them. Those streaks and the upward curl toward the front of the cloud classifies these as Cirrus Uncinus Clouds. The National Weather Service says in Latin this type of cloud is simply translated into "a curl or tuft of hair with a hook." These usually happen at 25 to 30 thousand feet high. OK, so that is what these clouds are, and I know I haven't yet answered what causes these, so here we go. Warm air usually arrives in the upper levels of the atmosphere before it arrives at the surface. Also with height, winds change and pick up speed. The ice crystals the winds interact with get stretched out into these curly, wispy formations. They are also known as "mare's tails." There is an old saying that comes along with these clouds, "Mares tails and mackerel scales make lofty ships carry low sails" . "Mackerel scales" are a type of mid level cloud. Both of these usually appear before a front moves into the area. The National Parks Service says neither of these cloud types will bring rain or snow themselves. They do, however, precede an approaching front by a day or two. So, you have a cool cloud that can sometimes predict the weather -- at least part of the weather.
