It’s 3:45 pm, the sky has already given up for the day, and every lamppost on Regent Street is glowing like it’s auditioning for a Christmas film. You’re clutching a hot chocolate in one glove, an umbrella is trying to escape your other hand, and you’ve just realised your “cute” boots have the grip of a wet bar of soap.
Welcome to London in December. It’s magical, it’s damp, and it’s far more walkable than your packing list probably assumes. The Tube is boiling, the pavements are freezing, and the weather changes its mind between the National Gallery and lunch.
I’ve watched people shuffle round Covent Garden in thin trainers and a puffer that makes them look like a sleeping bag with legs. Let me save you from that. Here’s exactly what to wear, what to leave at home, and how to look like you belong.
Before We Dive In
Let me be honest: December in London isn’t snowy-postcard cold. It’s wet-cold, and that’s a different beast.
Weather: Daytime highs sit around 7–9°C (45–48°F), nights drop to roughly 2–4°C (36–39°F). Rain is frequent, it’s often drizzly rather than dramatic, and the humidity makes it feel colder than the number suggests. Snow? Rare. Don’t pack for it.
Daylight: The sun rises around 8 am and sets before 4 pm. Your “evening outfit” starts at lunchtime, so plan for dusk to be your default lighting.
Walking conditions: You’ll cover serious ground. Pavements get slick, there are Tube stairs everywhere, and a day of Christmas markets easily means 20,000 steps.
Style culture: Londoners dress in dark, tailored, practical layers. Think wool coats, good boots, and quiet confidence. Nobody’s wearing a neon rain poncho, and you don’t need to either.

The Bag Situation: Carry-On or Bust
Here’s the thing about December packing: bulky clothes eat suitcase space for breakfast.
I’m firmly Team Carry-On, even in winter. A 40-litre carry-on-size travel backpack or a soft-sided cabin case does the job, and you’ll thank yourself on the Elizabeth line when you’re hauling it up a flight of stairs with no lift.
Wear your heaviest items (coat, boots, chunkiest knit) on the plane, and pack the rest. A packing cube set keeps your sweaters compressed, which matters when wool takes up twice the room of cotton.
Local tip: Many older Tube stations have lots of stairs and narrow platforms. A rolling suitcase is a nightmare there. A backpack or duffle is far kinder.
Layers, Layers, Layers (and Why Tube Heating Will Test You)
The secret to London in December isn’t one warm piece. It’s three thinner ones.
You’ll step out of a freezing street into a scorching Tube carriage, then a heated museum, then back into the wind. A single huge coat leaves you sweating or shivering with nothing in between.
Start with a thin base layer or merino tee. Add a mid-layer, like a knit sweater or fine-gauge cardigan. Finish with your coat. When the Central line turns into a sauna, you peel one layer and carry on.
Local tip: Merino beats cotton here. It stays warm when damp and doesn’t smell after a long day of sightseeing, so it’s brilliant for packing light.
The Coat: Your One Big Investment
If you only spend money on one thing, make it this.
A wool or wool-blend coat in black, camel, navy or charcoal is basically London’s unofficial uniform. It looks sharp at the theatre, holds up in the drizzle, and works over jeans or a dress. Aim for knee-length or longer; a cropped jacket leaves your thighs exposed to the wind.
If rain is forecast every single day (and in December, it kind of is), consider a trench-style coat with a removable liner, or pair your wool coat with a compact umbrella. A big puffer works for wind and cold, but a long, sleeker one looks more London than a boxy ski jacket.
Local tip: Check that your coat has deep pockets. You’ll want somewhere to stash gloves, your Oyster card or phone when you’re juggling a coffee.
Jeans, Trousers or a Skirt? (Spoiler: Not Shorts)
Let me save you the suspense: dark denim wins.
Dark, straight or slightly relaxed jeans are the most London thing you can wear. They hide splashes, dress up with boots, and don’t scream “tourist”. Skip the very light washes, which show every puddle splash by lunchtime.
Wool trousers or tailored black trousers are great for the theatre or nicer restaurants. And if you love skirts, a midi in wool or knit works beautifully, as long as you wear it with warm tights and tall boots.
Fleece-lined tights are a revelation, by the way. I learned this the hard way after one miserable evening on the South Bank.
Local tip: Avoid thin leggings as outerwear. They offer zero wind protection and read as gym wear rather than city style.
Shoes That Survive Wet Pavements
London in December is where pretty shoes go to die. Choose wisely.
Waterproof leather ankle boots with a grippy sole are my number one pick. A Chelsea boot or a lace-up with a lug sole looks stylish and keeps your feet dry. For a more casual day, clean leather trainers with a decent tread do the job, though canvas sneakers soak through in seconds.
Tall boots work wonderfully with skirts and dresses, but break them in before you fly. Blisters on day one of a sightseeing trip are a heartbreak.
Skip the wellies unless you’re heading to the countryside, and leave the heels for the theatre (you can pack ballet flats or small block heels to swap in).
Local tip: Spray your boots with a waterproofing treatment a few days before you leave. Cheap, quick, and genuinely life-changing.
Knitwear That Does the Heavy Lifting
A good jumper does half the work for you.
A chunky wool or cashmere-blend sweater in a neutral colour is a December workhorse. Roll necks (turtlenecks) are especially useful, since they replace a scarf on mild days and layer under a coat on colder ones.
Pack two or three knits and rotate them. Black, cream, grey, and a single colour you love (burgundy, forest green or navy are very London) will mix with everything and still look intentional in photos.
Avoid itchy synthetics. If you run warm, choose finer knits you can layer, rather than one massive Christmas-sweater-style piece.
Local tip: A slightly oversized knit tucked into straight jeans is the easiest “I woke up like this” London look.
Scarf, Hat, Gloves: The Small Stuff That Changes Everything
Here’s what surprised me: accessories make or break your comfort.
A big wool scarf is your best friend. It adds warmth, works as a blanket on cold trains, and instantly elevates a plain outfit. Pick one in a rich colour or a classic check.
Pack a beanie or wool hat, too, because wind chill near the Thames is no joke.
And gloves with touchscreen fingertips save you from the “take them off to buy a ticket” dance.
Wool socks (a couple of pairs of merino, ideally) are the unsung heroes of the entire trip.
Local tip: Keep your scarf, hat and gloves in your coat pocket or bag, ready to go. You’ll put them on and off a dozen times a day.
The Rain Plan Nobody Packs For
Let’s talk umbrellas.
A compact, sturdy travel umbrella is essential. Cheap ones turn inside out in gusts, so choose one with a vented canopy. Hooded coats also help, because wind plus umbrella equals chaos on a bridge.
A lightweight waterproof shell can work as a top layer beneath or instead of a wool coat on very wet days. Bring a small dry bag or waterproof cover for your phone and a spare pair of socks if you’re out all day.
Local tip: Skip the oversized golf umbrellas. They’re a hazard on crowded pavements and will earn you some withering looks on Oxford Street.
The Right Bag: Crossbody Beats Backpack
For daily sightseeing, a crossbody bag is a revelation.
It keeps your hands free for tickets, cocoa and umbrellas, and sits securely against your body on busy Tube platforms and market crowds. Pick one with a zip and enough room for a phone, wallet, gloves and a small umbrella.
A small backpack is fine for museum days when you need more room, but wear it on your front on packed trains. Choose a dark colour and a simple design; it blends in far better than a bright hiking daypack.
Local tip: Pickpockets target tourists around popular spots like Oxford Street and Camden. A zipped crossbody worn in front is your best defence.
Evening Outfits: Dress Like You Live Here
Londoners dress up for dinner and the theatre, but in a very relaxed way.
For women, a simple black dress or midi skirt with opaque tights and boots, topped with your wool coat, ticks all the boxes. A silk-feel blouse with tailored trousers also works, and a statement earring or a belt adds polish without effort.
For men, dark jeans or chinos, a good knit or button-down, and clean leather shoes or boots are plenty. A blazer upgrades the look for fancier venues.
Keep the palette muted: black, navy, burgundy, forest green. Sequins are fun if you’re going to a festive party, but for a standard dinner they might feel a bit much.
Local tip: Check if your restaurant or theatre has a dress code, but 95% of the time smart-casual is perfect.
What NOT to Wear in London in December
Quick-fire tourist mistakes I’ve seen over and over:
Don’t wear thin canvas shoes, because the pavements will soak them in minutes. Skip big white trainers on rainy days; they’ll look grey by lunchtime. Avoid fully cropped jackets, shorts, and ultra-light “spring” coats, no matter what the sunshine tricks you into thinking for twenty minutes.
Leave the novelty Christmas jumpers at home unless you’re going to a specific party. And please don’t dress head-to-toe in tourist-slogan hoodies; the weather is a good enough excuse to wear something cosy and good.
Local tip: When in doubt, go darker, plainer and better-fitting. London style is understated.
Fabrics to Choose (and Avoid)
Fabric matters more than fashion here.
Choose wool, merino, cashmere blends, thick cotton, and leather. They hold heat, repel damp air and look better the more you wear them. Corduroy is also a wonderful winter fabric: warm, textured and very London.
Avoid thin cotton, linen and cheap polyester. They feel cold and clammy in damp weather and don’t insulate well. Anything that takes forever to dry is a poor packing choice, since the English drizzle doesn’t help laundry.
Local tip: Check labels for “wool blend” or “merino” before packing. A 3-second check can save a miserable day.
Non-Clothing Essentials Worth Packing
A few small items make a big difference.
Pack a portable phone charger, because cold drains batteries fast and you’ll be using maps all day. Hand cream and lip balm fight the dry winter air, and a small pack of tissues is surprisingly handy.
A contactless card (or phone) for the Tube and a UK plug adapter (Type G) are musts. A reusable water bottle helps, too; London tap water is perfectly fine to drink.
Local tip: If you’re visiting Christmas markets, bring a little cash and a pair of hand warmers. Your fingers will thank you.
The Practical Bit: How Much to Pack
Here’s my rule of thumb for a 4–5 day trip: one coat, two pairs of bottoms, three to four tops, two knits, one nicer outfit, and two pairs of shoes. Add underwear and socks for each day plus one.
Packing light means mixing and matching. Stick to a colour palette (say, black, cream, navy, one accent) so everything works together. Wear your bulkiest items on the flight to save space.
Mistakes I see constantly: bringing three “just in case” outfits that never leave the suitcase, packing too many shoes, and forgetting that you can re-wear jeans and knits easily. Most hotels and flats also have laundry access if you need it.
Local tip: Lay out your outfits before packing. If you can’t make at least three combinations from one item, leave it behind.
FAQs About London in December Packing
Do I need a heavy winter coat? A good wool coat or insulated jacket is plenty. Layers matter more than a single huge parka.
Is it going to snow? Unlikely. Cold, grey and damp is far more typical, so waterproof footwear beats snow boots.
Can I wear trainers? Yes, if they’re leather or water-resistant, and clean. Canvas ones will be soggy by mid-morning.
What should I wear to a West End show? Smart-casual. Dark jeans or trousers with a nice knit or blouse is perfect.
Do I need an umbrella? Always. Pack a compact, wind-resistant one.
One Last Thing Before You Go
London in December is honestly one of my favourite versions of the city. The lights, the markets, the pubs with fires crackling, steamy windows and mulled wine in your hand. It’s cosy in a way the summer simply can’t match.
Pack the warm coat, the good boots and a scarf you love, and you’ll walk through every cold street feeling stylish, comfortable and ready for whatever the weather throws at you.
Go and enjoy it. Wrap up, look up at the lights, and let the city do the rest.
