You've probably seen the postcards. Big Ben covered in a thick, marshmallow layer of white, or the red buses looking like toys in a giant snow globe. It looks magical. It looks like a Dickensian dream. But if you’re standing on Oxford Street right now looking at the sky and asking is it snowing in London, the answer is probably a resounding, soggy "no."
London weather is a bit of a tease.
We get the cold. We get the grey. We definitely get the rain. But actual, bone-fide, "let's build a snowman" snow? That’s a rare beast in the capital. While the Scottish Highlands or even the Pennines might be buried under drifts, London often sits in a stubborn little bubble of lukewarm air that turns every promising snowflake into a sad, grey slush before it even hits the pavement.
Why London is basically a giant radiator
It isn't just bad luck. There is actual science behind why you're looking at a puddle instead of a drift. London is what meteorologists call an Urban Heat Island. Think about it. You have millions of people, millions of heaters, thousands of underground trains radiating heat, and endless miles of dark asphalt absorbing every bit of sunlight.
According to the Met Office, temperatures in the center of London can be up to 10°C higher than the surrounding rural areas.
That is a massive gap.

So, while a village in the Cotswolds is enjoying a winter wonderland, London is just... damp. The "City" creates its own microclimate. By the time a snowflake falls through that layer of urban warmth, it loses its structure. It becomes "sleet"—which is basically just rain that’s trying too hard. If you really want to see snow when a cold front hits, you usually have to head to the outskirts. Places like Highgate, Hampstead Heath, or the higher ground in Crystal Palace are your best bets. They’re just high enough and just far enough from the concrete heat to actually hold onto the white stuff for more than ten minutes.
The chaos of a single snowflake
British people love to joke about how the country falls apart when it snows. It’s funny because it’s true. In 2022, a relatively minor dusting caused absolute mayhem at Stansted and Gatwick.
Planes were grounded.
Trains stopped.
The M25 became a parking lot.
Why? Well, London isn't built for it. We don't have the massive fleet of snowplows you’d find in Oslo or New York. It doesn't make financial sense to buy them for something that happens maybe twice a year. So, when it does snow, the city panics. Transport for London (TfL) works incredibly hard to keep the Tube running—since most of it is underground, it’s usually the safest bet—but the Overground and the buses? Forget about it. The moment the road gets icy, those iconic double-deckers become very expensive sleds.
Checking the real-time data
If you’re looking at the grey sky and wondering if today is the day, don’t just trust the weather app on your phone. Those things are notoriously "general." Instead, look at the Netweather Radar or the Met Office Rainfall Radar.

These tools show you the "type" of precipitation.
On these maps, rain is usually blue, but snow is shown in white or pink. If you see a big pink blob heading toward the M25, start looking for your gloves. Also, keep an eye on the "dew point." This is a bit nerdy, but it’s the only stat that matters. If the air temperature is 2°C but the dew point is below zero, you might actually get snow that sticks. If the dew point is 1°C or 2°C, it's just going to be a cold shower. Honestly, the dew point is the secret weapon of every amateur UK weather watcher.
Historical "Big Snow" events in the Big Smoke
We do get hits sometimes. Real ones.
- 1963 (The Big Freeze): This was legendary. The Thames actually froze over in parts. People were skating on it. It stayed cold for months.
- 1987: A massive dumping of snow that paralyzed the city right before the "Great Storm."
- 2009: I remember this one vividly. London saw the heaviest snowfall in nearly 20 years. The city effectively shut down for a day, and everyone went to the park to build snow-versions of the Gherkin building.
- 2018 (The Beast from the East): This was a weird one. Cold air blew in all the way from Siberia. It wasn't just snow; it was bone-chilling, painful wind. The fountains in Trafalgar Square froze solid.
These events are outliers, though. Mostly, a London winter is a long, dark stretch of 6°C and drizzle.
How to survive a London "Snow Day"
If the miracle happens and the answer to is it snowing in London is "Yes, and it’s sticking," you need a plan. The city changes instantly. It gets quiet. That constant low-frequency hum of traffic disappears because nobody wants to drive.

- Get to a park immediately. Greenwich Park, Primrose Hill, or Richmond Park are elite-tier snow locations. The views of the skyline through the falling snow are genuinely world-class.
- Avoid the 'Slippy' pavements. London’s paving stones are beautiful but deadly. When they get a thin layer of compressed snow on them, they turn into a skating rink. Walk on the grit if you can find it.
- Check your apps. Use the Citymapper app. It is way more reliable for real-time London transport chaos than Google Maps. If a line is suspended due to "adverse weather," Citymapper will usually tell you first.
- Pubs with fires. This is the ultimate London move. Find a pub in Hampstead or Highgate with a real roaring fire. There is nothing—and I mean nothing—better than watching the snow fall through a leaded-glass window while holding a lukewarm pint of ale.
What to expect for the rest of 2026
The climate is changing, and that makes London snow even harder to predict. We’re getting more "extreme" events but fewer "consistent" cold snaps. We might get a random blizzard in March (it's happened!) or a totally green, mild February.
Statistically, January and February are your best windows. December snow in London is actually quite rare, despite what the Christmas songs tell you. We usually get "White Easter" more often than "White Christmas."
Practical Next Steps
If you are currently in London and hoping for snow, or planning a trip to see the wintry sights, do these three things right now:
- Follow @MetOffice on X (Twitter): They post the most accurate short-term warnings for the London region.
- Download the 'Netweather' app: Use the radar feature to track the "precip type" in real-time. Look for the white/pink colors on the map moving toward the M25.
- Prepare your gear: London "wet cold" is different from "dry cold." You need waterproof shoes. Suede boots will be ruined in seconds by the salty, slushy grime that coats the streets about an hour after the snow starts.
Snow in London is fleeting. It’s here, it’s beautiful for three hours, and then it turns into a grey Slushie that lingers in the gutters for a week. If you see it falling, drop everything and go outside. You never know when the heat island will win again and turn the next flurry into rain.
