Winter aurora chasing in Norway: clothing, cold and safety

A good aurora night in northern Norway can mean three hours standing on a snowy plain at minus fifteen with a bit of wind. That is not dangerous if you are prepared, but cold, darkness and icy roads are what usually go wrong, not the aurora. This guide covers the practical side: clothes that keep you warm while standing still, the signs of frostbite and hypothermia, where to stop the car, and what to do if something happens.

Dress for standing still

The most common mistake is dressing as if for a walk. When you walk, your body makes plenty of heat. When you wait for the aurora to switch on, you make almost none, and the cold creeps in after half an hour. Dress warmer than you think you need, and keep an extra layer in your bag or car.

Layering is the classic Norwegian approach (Norwegians call it lag-på-lag):

• Base layer: wool. Wool keeps you warm even when slightly damp. Avoid cotton next to the skin; it gets wet and cold.
• Mid layer: something that insulates well, such as a thick wool sweater, fleece or a light down jacket.
• Outer layer: windproof and waterproof jacket and trousers, or a thick down or synthetic parka to pull over everything while you stand still.

Wind makes a big difference. Weather apps often show a "feels like" temperature next to the measured one, and on the coast it can be many degrees lower than the thermometer. Factor that in, and shelter behind the car, a building or a slope while you wait.

Hands, feet and face

According to NHI, a Norwegian health information service, hands, feet, nose and ears are the most exposed to frostbite, and children get cold injuries more easily than adults. A few simple measures:

• Mittens are warmer than gloves. Wear thin liner gloves underneath so you can work a camera or phone without going bare-handed.
• Bring spare mittens and socks. Damp socks after a day out are a common cause of cold feet.
• Winter boots with a good sole and a roomy fit. Tight footwear restricts circulation.
• A hat that covers your ears, and a neck gaiter. Note that a scarf over your mouth gets damp from your breath and can contribute to frostbite.
• A hot drink in a thermos helps both mood and temperature.

Recognising frostbite: The skin becomes hard, pale and cold, and with deeper injury white or waxy-yellow and numb. Check each other's faces, especially nose, cheeks and ears. Get into shelter, warm the area with body heat (hands in your armpits, a warm hand against a cheek), and do not rub it with snow. Do not hold numb skin up to a fire or heater either, as you can burn it without feeling it. If feeling and colour do not return, get medical help.

Hypothermia: when the whole body gets too cold

Norway's official health portal, Helsenorge, describes hypothermia in stages: mild (awake and shivering), moderate (reduced consciousness, no longer shivering) and severe (unconscious). Someone who stops shivering without having warmed up is therefore showing a danger sign, not getting better.

First aid is to remove wet clothing, wrap the person so they are protected from wind and moisture, add heat (for example bottles of hot water, not directly against the skin), get them indoors if possible, and call 113 for guidance.

Cars, roads and parking

The biggest practical problem in aurora season is not the cold but the traffic. People brake suddenly, park on the verge and walk into the road with tripods in the dark. Do the opposite:

• Stop only at rest areas, car parks or wide lay-bys well off the carriageway. Never on a bend, a crest or at a junction.
• Put on a reflective vest when you leave the car. The Norwegian Public Roads Administration (Statens vegvesen) says a driver at 50 km/h on dipped headlights has only about 2 seconds to spot a pedestrian without reflectors, compared with 10 seconds with them.
• Turn off full beam and do not shine lights at people photographing, but use hazard lights if the car could be in anyone's way.
• Respect private property, farmyards and snow-plough turning areas. A plough needs room to turn.

Winter driving: Check road reports at vegvesen.no/trafikk or in the Vegvesen trafikk app, or call 175 (the road traffic centre, open 24/7; from a foreign phone +47 22 175 175). Mountain passes in Troms and Finnmark can close or switch to convoy driving (kolonnekjøring) in bad weather. A snowplough or escort vehicle then drives at the front and back, and the road authority asks you to have a full tank or charged battery, a torch, tow rope and snow shovel, food, a hot drink and warm clothes. If the convoy stops, do not walk away from your car. Carry extra clothing in the car in winter, even on short trips.

Light and darkness

A head torch is essential, but use it with care. Many aurora watchers use red light because it feels less disruptive to night vision than bright white light (this is common practice, not something we have checked against a scientific source). Your eyes need many minutes in the dark to see faint aurora well, so avoid staring at a full-brightness phone screen. Our article on aurora colours explains why your eyes and your camera see differently.

Cold drains batteries quickly. Keep your phone and a power bank in an inside pocket close to your body, and bring a charger for the car. Your phone is also your emergency phone.

Terrain, avalanches and ice

You rarely need to walk far to see the aurora, and the safest spots are often flat, open areas close to a road. If you do head into the mountains:

• Check the avalanche forecast at varsom.no. The Norwegian Water Resources and Energy Directorate (NVE) issues danger levels from 1 (low) to 5 (very high) for regions such as Tromsø, Lyngen, Lofoten og Vesterålen and Vest-Finnmark.
• Stay away from steep slopes and terrain traps unless you have the training and equipment.
• Be very careful on frozen lakes, rivers and sea ice. The ice can be unsafe, and in the dark you cannot see open water or slush.
• Follow the Norwegian mountain code (fjellvettreglene): plan your trip and tell someone where you are going, take weather and avalanche forecasts into account, and turn back in time. There is no shame in turning around.

Svalbard has its own rules because of polar bears. See the aurora on Svalbard and the Governor of Svalbard's (Sysselmesteren) official pages before going outside Longyearbyen.

Emergency numbers in Norway

According to Nkom, Norway's communications authority, 112 can be reached without a SIM card or coverage from your own operator, as long as at least one network has coverage where you are. When you call an emergency number, the service usually receives your location automatically.

Checklist before you go

• Three layers of clothing, spare mittens and socks, hat and neck gaiter
• Thermos with a hot drink and a snack
• Head torch, charged phone and power bank
• Reflective vest
• Checked weather, cloud cover and road reports, and told someone where you are going
• And of course: check tonight's verdict for your location before you drive

In short

Dress for standing still, not for walking: wool next to the skin, insulation in the middle and windproof on the outside, plus spare mittens and socks. Know the signs of frostbite and hypothermia. Park only where it is safe, wear a reflective vest and check road reports. Stay out of avalanche terrain and off uncertain ice, and remember 112 and 113. To decide when it is worth heading out, start with cloud cover and the Kp index.
