Deciding what to wear in London in December is mostly about staying warm without dressing so heavily that you become uncomfortable indoors. Expect chilly, damp weather, short days, plenty of walking, and regular moves between cold streets and heated shops, museums, restaurants, and public transport. The most practical approach is a warm coat, adjustable layers, weather-resistant shoes, and a few compact winter accessories.
Quick Answer
For London in December, wear a warm coat over two or three light layers, then add comfortable water-resistant footwear, a scarf, gloves, and a hat. Keep rain protection handy. Layers work better than one bulky outfit because you can remove them easily when you enter warm indoor spaces.
Key Takeaways
- Build your outfit around removable layers rather than one extremely heavy garment.
- Choose a warm coat that can cope with damp, breezy conditions.
- Comfortable shoes with water resistance and useful grip are better suited to long sightseeing days.
- A scarf, gloves, and hat add warmth without taking much room in your luggage.
- Keep one slightly smarter outfit or layer if your plans include an upscale restaurant, party, or other venue with a dress code.
What Is London Weather Like in December?
London in December is normally chilly rather than severely cold, but damp weather can make long periods outdoors feel colder. The Met Office’s 1991–2020 Heathrow climate averages put the average December maximum at 8.79°C (47.8°F) and the average minimum at 3.08°C (37.5°F).
| December climate measure | Heathrow 1991–2020 average |
|---|---|
| Daily maximum temperature | 8.79°C (47.8°F) |
| Daily minimum temperature | 3.08°C (37.5°F) |
| Monthly rainfall | 57.05 mm |
| Monthly sunshine | 54.96 hours |
Visit London’s weather guidance describes typical winter temperatures as about 2°C to 10°C (35°F to 50°F). Temperatures do not often fall below freezing, and snow is uncommon, although it can occur.
Rain and wet pavements are more useful to plan around than deep snow. December also has limited daylight, so an outfit that stays comfortable from daytime sightseeing through an early-dark evening is especially useful.
How to Layer Clothes for London in December
Layering is the easiest way to dress for London in December because each layer can be added or removed as conditions change. Instead of relying on one very thick sweater, combine a comfortable base, an insulating middle layer, and a protective coat.
A fitted long-sleeve top or turtleneck works well as the first layer. It adds warmth without creating much bulk under sweaters and coats. If you are especially sensitive to cold, a lightweight thermal top can serve the same purpose.
Your middle layer can be a jumper, cardigan, fleece, or other warm knit. Choose something you can comfortably wear by itself when you remove your coat indoors.
This multiple-layer approach also matches NHS cold-weather guidance, which recommends several layers of clothing rather than relying on one chunky layer.
Pro Tip: Make sure every layer fits comfortably beneath the next one before your trip. A coat that fits perfectly over a T-shirt may feel restrictive once you add a jumper and scarf.
Choose a Warm Winter Coat
Your coat is the main barrier between you and London’s December weather. It should provide enough warmth for extended walks while leaving enough room underneath for at least one insulating layer.
Wool and wool-blend coats work well when you want a smarter appearance. Puffers and insulated jackets are practical choices for casual sightseeing, especially if you expect to spend a long time outdoors.
A longer coat can provide extra coverage over your hips and upper legs. Whatever style you choose, prioritize comfortable movement and practical weather protection over a coat that looks good but becomes awkward during a full sightseeing day.
Neutral shades such as black, grey, navy, or camel are easy to combine with several outfits. A brighter coat can work just as well if you prefer more colour. There is no need to change your normal personal style simply because you are visiting London.
Bring a Scarf and Gloves
A scarf and gloves are small items that can make a noticeable difference when you spend hours outdoors. They are particularly useful on colder evenings, during riverside walks, or while standing outside rather than continuously moving.
Scarves range from thick knits to lighter wool options. Choose one that fits comfortably inside or over your coat collar without restricting movement.
Gloves can be knitted, fleece-lined, or leather depending on the level of warmth and formality you want. Touchscreen-compatible gloves are convenient if you regularly use your phone for maps, tickets, photos, or transport information.
You do not need to match every accessory. However, coordinating your scarf and gloves with the coat can give a simple winter outfit a more finished appearance without adding extra clothing.
Wear Comfortable, Weather-Resistant Footwear
Footwear deserves as much attention as your coat because London sightseeing usually involves substantial walking. Choose shoes that are already comfortable, provide useful grip on damp surfaces, and will not become unpleasant after light rain.
Water-resistant ankle boots are a practical option because they can work with jeans, trousers, skirts, and dresses. A pair with a stable sole is generally more useful for sightseeing than delicate fashion footwear.
Winter-ready trainers can also work when they provide enough warmth and weather protection. Ordinary breathable fabric trainers may become uncomfortable if they get thoroughly wet, so consider the forecast and how much time you plan to spend outside.
Knee-high boots can provide additional leg coverage and pair well with skirts or dresses. Heavy snow boots are usually unnecessary for a normal central London trip because snow is not common.
Pro Tip: Break in your main walking shoes before travelling. December is a poor time to discover that a new pair rubs your heel after an hour of walking.
Use Sweaters and Knits as Your Mid-Layer
Sweaters and other knits give you insulation without forcing you to wear an extremely heavy coat. They also make it easy to build several outfits from a relatively small travel wardrobe.
A turtleneck works well beneath a coat for a clean, simple look. Crew-neck jumpers and cardigans are more flexible if you expect to remove layers frequently.
You can also use texture or pattern to give a winter outfit more personality. Cable knits, stripes, checks, and traditional winter patterns add visual interest without changing the basic layering system.
For a practical travel wardrobe, choose sweaters that work with more than one pair of trousers, jeans, or skirts. This reduces luggage while still giving you several combinations.
Consider Waterproof or Water-Resistant Outerwear
Rain protection matters in London because a cold day becomes much less comfortable once your clothes are wet. A waterproof or water-resistant outer layer is therefore a sensible choice when the forecast calls for showers.
A practical rain-resistant coat does not have to look like hiking gear. Many trench coats, parkas, puffers, and insulated jackets combine weather protection with a city-friendly design.
If your main wool coat is not designed for rain, carry an umbrella when wet weather is likely. A hood is also useful because it leaves your hands free when you are walking, carrying bags, or checking directions.
Water resistance is especially useful in footwear. Keeping your socks and feet dry can make a bigger difference to comfort than adding another decorative layer to the outfit.
Dress for Both Indoor and Outdoor Activities
A good London December outfit should work in more than one environment. You may spend part of the day walking outdoors, then move into museums, shops, cafés, restaurants, theatres, or public transport.
For sightseeing, a typical combination might be a long-sleeve top, jumper, trousers or jeans, warm coat, scarf, and comfortable boots. You can remove the coat and scarf once you are indoors.
If you prefer skirts or dresses, tights provide extra warmth without changing the overall look. Add boots and a coat that covers enough of your legs to remain comfortable outside.
For outdoor festive activities, markets, or long evening walks, add the warmer accessories you can easily remove later. Standing still usually feels colder than continuously walking, so gloves and a hat become more useful during these activities.
Casual clothing is suitable for most sightseeing in London. If you are visiting an upscale restaurant, private event, party, or venue with a stated dress code, keep one smarter outfit or adaptable layer for that occasion.
Add a Hat or Beanie on Colder Days
A hat provides extra warmth without taking much luggage space. Beanies are particularly practical because they pack easily and work with most casual winter outfits.
If your style is more formal, a structured wool hat can work with a tailored coat. Earmuffs are another option if you prefer to keep your hairstyle uncovered while protecting your ears from the cold.
The most useful choice is one you will actually wear. A stylish hat that spends the entire trip in your suitcase offers less value than a simple beanie that fits comfortably under your hood and stays with you throughout the day.
What to Pack for London in December
A compact wardrobe can cover most December plans if the pieces work together. Start with the essentials, then adjust the quantity to your trip length and access to laundry.
- Warm winter coat: wool, insulated, puffer, parka, or another style suitable for chilly weather.
- Water-resistant layer or rain protection: especially useful when showers are forecast.
- Base layers: long-sleeve tops, fitted turtlenecks, or lightweight thermal tops.
- Mid-layers: jumpers, cardigans, fleece, or other warm knits.
- Trousers or jeans: comfortable enough for long periods of walking and sitting.
- Optional skirt or dress: pair it with tights and boots for warmth.
- Comfortable weather-resistant shoes: ideally a pair you have already worn for long walks.
- Warm socks: particularly useful with boots.
- Scarf: easy to add or remove as temperatures change.
- Gloves: useful for colder mornings and evenings.
- Hat or beanie: compact protection for colder or breezier periods.
- Umbrella: a practical backup when rain is expected.
- One smarter outfit or layer: useful if your itinerary includes a venue with a dress requirement.
What Should You Avoid Wearing?
Avoid building your entire wardrobe around thin warm-weather fabrics, open-toed shoes, or footwear that performs poorly when wet. These choices can leave you uncomfortable during long periods outside.
You also do not need to pack only bulky sweaters. Several thinner pieces usually give you more control over your temperature and are easier to reuse in different combinations.
Be cautious with shoes chosen purely for appearance. High heels, thin soles, new footwear, and materials that you do not want exposed to rain can become inconvenient on long sightseeing days.
Finally, do not assume every December day will feel the same. Conditions vary, so a flexible set of layers is more useful than planning one fixed outfit for the whole trip.
