Whitehorse, the capital of Canada’s Yukon Territory, is one of the most rewarding places to be in the depths of winter.
The snow is deep and squeaky underfoot, the sky is often clear enough to show the northern lights, and the town has a warm, welcoming character that makes the cold feel like part of the adventure.
But the weather is not mild. Arrive underdressed and the cold will cut your trip short.
Arrive prepared and you will be comfortable, safe and free to enjoy everything the Yukon has to offer.
This guide explains exactly What to Wear in Whitehorse in December, layer by layer, from your skin to your outer shell.
It also covers footwear, accessories, activity-specific clothing, common mistakes and a packing checklist you can copy into your notes.
What the weather in Whitehorse is really like in December
December is one of the coldest months in Whitehorse.
Daytime highs typically sit between -10°C and -15°C (about 14°F to 5°F), and nighttime lows often drop to -20°C or colder.
Cold snaps are a normal part of Yukon winters, and temperatures of -30°C or lower can last for several days.
Occasionally a warm spell pushes temperatures closer to freezing, so conditions can change more than visitors expect.
Three features of the climate shape how you should dress:
Short days. Around the winter solstice, Whitehorse gets only about five hours of daylight.
The sun stays low on the horizon, so even midday can look like twilight.
You will spend a lot of time outside in the dark, when it is coldest, whether you are watching the aurora or walking to dinner.
Dry air. The cold here is sharp and clean rather than damp, and with the right clothing it is far more tolerable than the same temperature in a humid place. The dryness is hard on skin, lips and eyes, though.
Wind chill. Calm days are common, but when the wind picks up, it can make it feel many degrees colder and increases the risk of frostbite on exposed skin. A windproof outer layer is not optional.
The good news is that Yukoners live and play here all winter.
The strategy is simple: dress in layers, protect your extremities, keep everything dry and stay flexible.
The golden rule: layers
Several thinner layers trap more warm air than one thick garment, and they let you adjust as conditions change.
You might be hot while walking briskly, then chilled when you stand still to watch the northern lights.
With layers, you can open a zip or remove a mid layer before you start sweating, which matters because sweat is what makes you cold later.
Think of it as three jobs: wick moisture away from your skin, hold heat in, and block wind and snow.
Layer 1: The base layer
The base layer manages moisture. It should fit close to your body without restricting circulation.
- Best fabrics: Merino wool or a good synthetic such as polyester. Merino is warm, soft, odor resistant and stays warm even when slightly damp. Synthetics dry quickly and are often cheaper.
- What to avoid: Cotton. It absorbs sweat and holds it against your skin, pulling heat away from your body. It is the most common mistake visitors make.
- How many: Two or three sets of tops and bottoms, so you can rotate them.
- Weight: Midweight suits most people. Choose heavyweight if you feel the cold easily or plan long evenings outside for aurora viewing.
Layer 2: The mid layer
The mid layer traps the heat your body produces.
- Fleece: Light, breathable and affordable. A mid-weight fleece pullover is a classic choice.
- Wool sweaters: Warm and stylish, and good for café and restaurant days.
- Light down or synthetic puffy jacket: Compresses small and provides excellent warmth for its weight. Wear it under your parka on the coldest days or on its own on milder ones.
- How many: Two mid layers of different thickness give you options.
Layer 3: The outer layer
The outer layer shields you from wind, snow and the deepest cold.
- Insulated parka: The foundation of your kit. Look for one rated to around -30°C or colder, with a long cut that covers your hips and upper thighs, a windproof outer fabric and a generous hood.
- The hood matters: A hood with a stiff brim or wire frame, ideally with a trim that breaks the wind around your face, makes a big difference.
- Features to look for: A two-way zipper so you can open the bottom when sitting, a storm flap over the zipper, adjustable cuffs, inner pockets for keeping a phone warm and room to wear a mid layer underneath.
- Down or synthetic? Down is warmer for its weight but loses insulation when wet. Synthetic keeps working when damp and is easier to care for. In the dry Yukon cold, down performs very well, but synthetic is more forgiving if you sweat a lot.
Bottoms
- Regular days: Thermal leggings under warm, loose trousers or lined pants work well around town.
- Long periods outside: Insulated snow pants or overpants over your base layer, especially for northern lights viewing, sledding and photography.
- Avoid: Jeans as your only layer. Denim is cotton, it does not insulate and it chills quickly.
Also Read: WHAT TO WEAR
Footwear: the most important decision you will make
If your feet get cold, your whole trip suffers. Good footwear is worth spending money on.
Winter boots
- Temperature rating: Look for boots rated to -30°C or colder, or even -40°C if you run cold. Choose conservatively.
- Removable liners: Felt or fleece-style liners that come out are ideal, because you can dry them overnight and start each day with warm boots.
- Sole: Thick and deep-lugged, made of a rubber compound that stays flexible in extreme cold. Some soles harden and become slippery.
- Waterproofing: A waterproof lower section keeps slush and melted snow out.
- Fit: Roomy enough to wiggle your toes while wearing thick socks. Tight boots restrict circulation and make your feet colder.
Socks and traction
- Choose merino wool or a wool blend, never cotton.
- One thick, well-fitting pair beats two thin ones. Stacking socks can squeeze your foot and reduce blood flow.
- Pack at least three or four pairs, and carry a dry spare in your day bag.
- Slip-on ice cleats are inexpensive, light and can prevent a nasty fall on icy sidewalks and packed snow.
Leave fashion boots with thin soles, canvas sneakers and rain boots at home.
They may look fine in photos, but your toes will regret them.
Head, face, hands and neck
Your extremities are the most vulnerable to cold and frostbite, because your body prioritizes keeping your core warm.
- Hat: A warm toque (the Canadian word for a beanie) that covers your ears is essential. On very cold days, choose one with ear flaps or a thick, lined band. A hat that fits under your hood is more practical than a bulky one.
- Neck gaiter or buff: Light and versatile. Pull it over your chin, nose and mouth when the wind bites.
- Balaclava: The best choice for very cold days, aurora nights or snowmobile tours.
- Scarf: A big wool scarf is comfortable and stylish in town, though a gaiter is safer if you are active.
- Sunglasses or goggles: Snow glare is strong, even in low winter light. Ski-style goggles protect your eyes from cold air on a sled or snowmobile.
- Mittens: They beat gloves for warmth, because fingers share heat when they are together. Wear thin liner gloves inside so you can use your phone or camera without exposing bare skin.
- Hand and toe warmers: Inexpensive disposable warmers fit inside mittens or boots and can be a lifesaver on long outdoor sessions.
- Skincare: Dry air cracks skin and lips. Pack a rich moisturizer, lip balm with sun protection and hand cream. Some people also carry saline nasal spray, since indoor heating dries the air even more.
What to Wear in Whitehorse in December activities
Northern lights viewing
This is the activity where people most often underestimate the cold.
You will spend hours standing or sitting still outdoors at night, often below -20°C.
- Wear your full layering system, including insulated snow pants.
- Choose your warmest boots with fresh, dry socks.
- Add a balaclava or gaiter, a warm hat and your best mittens.
- Bring chemical warmers and a thermos of a hot drink.
- Keep spare camera batteries inside your jacket, since cold drains them fast.
Many aurora tours include a heated lodge or teepee where you can warm up, but you will still spend time outside, so dress for it.
Dog sledding and snowmobiling
Moving at speed adds a lot of wind chill.
Windproof outer pants and jacket are essential, along with goggles, a face covering and insulated mittens.
Check with your tour operator first, because many companies provide snowsuits, boots and mittens for guests.
Borrowing them can save you buying or packing bulky items.
Snowshoeing, skiing and winter walks
If you are active, you will generate heat, so avoid overdressing.
Wear thinner mid layers that you can vent or remove, choose breathable base layers, carry an extra layer in a small pack and bring a spare pair of mitts.
Whitehorse has good trails for walking, snowshoeing and cross-country skiing.
Including areas around Miles Canyon and the Mount McIntyre Recreation Centre. Check conditions locally before you go.
Hot springs
Soaking in an outdoor hot spring in the snow is a highlight for many visitors, and Takhini Hot Springs is a popular option not far from town.
Wear your swimsuit under a warm layer for the walk to the pool and bring a hat to wear while soaking.
Pack dry clothes and a towel, put your boots on quickly afterward, and cover your hair, since wet hair can freeze fast.
Dining out and city days
Indoor spaces in Whitehorse are warm, and locals dress practically.
A good parka and boots are acceptable almost everywhere.
Wear a layer you can remove, such as a wool sweater over thermal underwear, and keep your hat and mittens within reach.
Common mistakes to avoid
- Wearing cotton. It holds moisture and pulls heat away from you.
- Dressing too tightly. Constricting layers, boots and gloves reduce circulation.
- Overdressing before you go outside. If you are sweating indoors, you will be cold in ten minutes. Start slightly cool and warm up as you move.
- Ignoring your face. Exposed skin can get frostbite in minutes in very low temperatures and wind. Cover your nose, cheeks and ears.
- Skipping spare gear. Carry spare socks, liner gloves and a dry hat on long outings.
- Forgetting your devices. Batteries drain in the cold. Keep phones and cameras in an inside pocket.
Staying safe in extreme cold
- Frostbite: Numb, waxy, pale or hard skin needs warming right away. Move indoors, remove wet clothing and warm the area gently. Do not rub it.
- Hypothermia: Shivering, confusion, slurred speech and clumsiness are warning signs. Get to a warm place quickly.
- Buddy up: Check each other’s faces for white patches in wind or extreme cold.
- If you rent a car: Ask about winter tires, a block heater cord and an emergency kit, and keep warm clothing, water and snacks inside.
- Check forecasts: Environment Canada issues extreme cold warnings, and tour operators adjust their plans accordingly.
