What to Wear on a Northern Lights Tour

5 July 2026

Standing under a swirling green sky is unforgettable — shivering under one is just cold. On a northern lights tour you are mostly standing still, at night, in winter, often somewhere windier and noticeably colder than Tromsø’s city centre. The good news: dressing for it is a solved problem. Here is exactly what to wear, layer by layer, plus what we provide so you do not have to buy an Arctic wardrobe for one holiday.

Think layers, not one big coat

Warmth comes from trapped air, and several thinner layers trap far more of it than one thick single layer ever will. Layers also let you adjust: you will be toasty in the minibus and cold on a windswept viewpoint, sometimes ten minutes apart, and the ability to open a zip or pull on one more piece is what keeps you comfortable across a 5–7 hour evening. Three layers on top, two on the bottom is the standard recipe for an aurora night.

Base layer: wool, never cotton

Start with thermal underwear — long johns and a long-sleeved top — ideally merino wool or a technical synthetic. Merino keeps insulating even when slightly damp and does not get clammy. Avoid cotton entirely: it soaks up sweat and then chills you as it dries. This single swap makes more difference than any expensive jacket.

Mid layer: your insulation

A fleece or wool jumper plus, on the coldest nights, a light down or synthetic puffer that packs small enough to stuff in a daypack. On your legs, fleece-lined trousers or a second thermal layer under your outer trousers — legs are forgotten surprisingly often, and they have a lot of surface area to lose heat from.

Outer layer: wind and waterproof

A windproof, water-resistant shell jacket and trousers — ski wear is perfect, and it does not need to be new or fancy. Wind is the great heat thief on exposed viewpoints: a modest breeze at −10°C feels far colder than still air at −20°C, so blocking it matters as much as the insulation underneath.

Hands, feet and head: where the night is won or lost

Feet: insulated winter boots with room to wiggle your toes, over one pair of thick wool socks. Tight boots squeeze out the insulating air and guarantee cold feet. Thin “fashion” sneakers are the number-one packing mistake we see.
Hands: mittens beat gloves — fingers warm each other. A thin liner glove underneath lets you work your camera or phone without exposing bare skin.
Head and neck: a warm hat that covers your ears and a buff or scarf for your neck and face. A lot of heat escapes from an uncovered head.
Extras: chemical hand warmers are cheap and glorious; slip one in each mitten and one in your camera pocket — cold drains phone and camera batteries fast. A small foam pad to sit or stand on is another veteran trick: snow steals heat through your soles slower when there is foam in between.

What Northern Lights Safari provides

You do not need to arrive equipped like a polar explorer. Thermal suits are available on our tours for the coldest nights — a warm overall that goes on top of everything else — and hot drinks and snacks are included while we watch the sky. Our guides also help with tripods and camera settings, and a high-quality photo of you under the aurora is included, so you can keep your hands in your mittens instead of fumbling with equipment. See the full list of what is included on the Classic Northern Lights Tour page.

Common mistakes to avoid

Dressing for the city, not the viewpoint. Tromsø’s harbour can be −2°C while a valley 90 minutes inland sits at −15°C. Dress for the coldest place the night might take you.
Cotton anything — socks, t-shirts, jeans. Once damp, cotton is a refrigerator you wear.
One pair of thin gloves. Bring mittens with liners; your camera fingers will thank you.
Overdressing for the bus and having nowhere to put layers. Wear the shell, carry the puffer — adjust as you go, and aim to be slightly cool when you first step outside so you are not sweating into your base layer.
Skipping dinner. You burn real energy keeping warm; eat properly before departure. There are snacks and hot drinks on board, but they top you up rather than replace a meal.
Forgetting your own comfort baseline: if you are usually cold, add a layer. Nobody has ever regretted packing an extra jumper in the Arctic.

The bottom line

One more Tromsø-specific note: the weather changes fast and often within a single evening, and the tour may cross from coastal drizzle into dry inland cold in under an hour. Dressing in adaptable layers is not just comfort advice here — it is how you stay happy through whatever microclimate the clear sky happens to be hiding in.

Wool base, warm mid, windproof shell, proper boots, mittens, hat — and let us handle the thermal suits, hot drinks and photography. If you are visiting between September and April, check when the northern lights season peaks in Tromsø to pick your dates, then book your evening under the sky: the Classic Northern Lights Tour runs nightly through the season, and the Multilingual Guided Aurora Tour offers the same chase with guiding in French, German, Spanish or Italian. Book direct for the best price, with free cancellation up to 24 hours before departure.
