Snow-Cleared London: When Will It Happen? (2024)

London rarely sees snow that settles, and when it does, it usually melts away quickly. This is due to the urban heat island effect, which makes the temperature in the urban centre of the capital higher than in the suburbs. However, there have been exceptions, such as the 'Beast from the East' in 2018, which brought 10 days of heavy snow to the UK.

While the Met Office has not forecast any snow for London in 2024 so far, Weather25.com predicts there could be icy flurries on 17 January. The Met Office also says that snow is more likely to fall in London between January and March than in December, so there could still be some snow on the way this year.

Snow in London is rare, but it does happen

Snow in London is a rare occurrence, but it's not unheard of. The UK's predominant wind direction is south-westerly, making snow unlikely in most areas. However, London does experience snow a few days a year, usually between November and April.

The central parts of London have fewer than 10 days of snow or sleet annually, and when it does snow, it rarely settles for long, thanks to the urban heat island effect. The snow often melts away quickly, and you're more likely to see accumulation in the suburbs or outskirts of the city.

The months of December to February offer the highest chance of snow, with London experiencing about 3-5 days of accumulating snow or sleet during this period. February is typically the snowiest month, with about 4 days of snowfall and 1-2 days of accumulation.

While a white Christmas in London is unlikely, you can still enjoy a magical winter wonderland when the city is dusted in white. Iconic landmarks like Tower Bridge, the London Eye, and the Tower of London take on an otherworldly feel when covered in snow.

If you're visiting London during the colder months, it's essential to dress appropriately. Layers and water-resistant materials are key to staying warm. Don't forget to pack a waterproof jacket, warm socks, a scarf, a hat, and gloves.

• Listen to weather reports and check for warnings.
• Embrace indoor activities like visiting museums, taking a hop-on hop-off bus tour, or enjoying afternoon tea.
• Be cautious of ice and avoid driving if possible.
• Stay warm by consuming hot drinks and eating energy-boosting foods.
• Keep an eye out for signs of hypothermia or frostbite and seek warmth indoors if needed.

The Met Office says snow is more likely between January and March than in December

Snow in London, while not unheard of, is rare. The city is usually a few degrees warmer than other parts of the UK throughout the year due to its dense population and urban infrastructure. London's average daily high temperature between December and February is about 48°F (9°C), and the average daily low is 41°F (5°C). Below-freezing temperatures do occur, but they are not common. Accumulating snow or sleet can be expected on only 3-5 days, mostly during the months of December, January, and February.

The Met Office, the UK's national weather service, states that snow is more likely to occur in the UK between January and March than in December. On average, snow or sleet falls on 3.9 days in December, compared to 5.3 days in January, 5.6 days in February, and 4.2 days in March.

In London, snow is most likely to occur in January, which is the city's coldest month. The average temperature in London in January is between 4°C and 9°C. While snow may fall in January, it is usually a small amount, and it will melt after a day or two.

February is also a relatively cold month in London, with temperatures as low as 4°C. It is not common for London to have snow in February, but with the cold temperatures, it is not unlikely.

By March, London is normally noticeably warmer, with average temperatures between 6°C and 12°C. Due to the warmer weather and the approaching spring season, it is very unlikely that there will be snow in London in March.

So, if you're wondering when the snow will clear in London, it's important to consider the time of year. While snow can occur in December, January, and February, it is typically short-lived and melts away quickly due to the urban heat island effect. By March, the chances of snow become very low as the city transitions into spring.

London's temperature is often higher than in surrounding areas, so snow melts quickly

London's temperature is also influenced by its location near the sea. The most common wind direction in the UK is south-westerly, which brings mild and moist air from the Atlantic Ocean. As a result, snow is a rare occurrence in most areas of the UK, including London.

When it does snow in London, it usually melts away very quickly and rarely settles on the ground. This is because the urban centre of the city often has a higher temperature than the surrounding areas. The outskirts of London and areas with higher altitudes tend to get more snow as it takes longer for snow to melt in these areas.

The exception to this was the ''Beast from the East' in 2018, when the entire UK experienced 10 days of heavy snow in late February. However, such events are rare, and in most years, London is free of snow from June to September.

The highest chance of seeing snow in London is during the winter months, particularly in January and February. However, even during these months, snow may only fall for a few days and quickly melts away.

The suburbs tend to see more snow accumulation

While snow is rare in London, it does occasionally fall in the city, usually during the months of December, January, and February. When it does snow, it rarely settles for long, especially in the urban centre of the city, where temperatures tend to be higher. This is due to the urban heat island effect, which causes snow to melt faster.

The suburbs, however, tend to see more snow accumulation. There are several reasons for this. Firstly, pavement and roads in the city centre are good absorbers of heat. They are also connected to the earth's surface, which means they can be warmed more quickly by the warmer soil beneath than grass or other vegetation in the suburbs.

Additionally, roads in the city, particularly those that are heavily trafficked, take longer to cool down than those in the suburbs. This gives falling snow a better chance to settle in suburban areas. Furthermore, snow that falls on grass is more likely to accumulate as grass absorbs excess water more efficiently than pavement.

Finally, snow removal and treatment methods in the city centre are often more efficient and frequent than in the suburbs. Pavements and roads in the city are often treated with salt and other melting agents, which significantly reduce snow accumulation. In contrast, snow removal in less populated suburban areas may be slower or less thorough, allowing more time for snow to settle and accumulate.

The UK transport system struggles in heavy snow, so expect delays and cancellations

When snow and ice accumulate on railway tracks, they can block points—the movable sections of track that enable trains to change lines. This can prevent trains from accessing certain routes or platforms, causing delays. Ice can also coat the electrified third rail and overhead power cables, causing trains to become stranded as they are unable to draw the power they need to run. In the event of heavy snowfall, trains without snow ploughs attached cannot run safely.

The UK's railway operators have a fleet of specialised equipment to deal with snow and ice on the tracks, including snow ploughs, hot air blowers, steam jets, scrapers, and anti-freeze. They also run empty "ghost trains" overnight to keep the tracks clear. However, despite these preparations, heavy snow can still cause significant disruptions to train services.

In addition to rail transport, air travel may also be impacted by heavy snow. Planes may be unable to take off due to icy runways and wings, as well as visibility issues.

It's important to plan ahead and expect delays or cancellations when travelling during snowy weather in the UK. Check for updates and allow for extra time when travelling to your destination.
