What to Wear on a Svalbard Day Tour
What operators provide, what you must bring yourself, and the layers that actually work at −15 °C — a season-by-season packing list for Svalbard day tours.
There is one rule that explains almost every Svalbard packing mistake: the operator provides the outer shell, and you provide everything underneath it. Snowmobile suits, drysuits, helmets, overalls, headlamps and ice spikes are handed out at the start of the tour. Base layers, mid layers, socks, hats and gloves are yours, and they are what decides whether you are warm.
Visitors arrive with an excellent coat and cotton underneath, then spend four hours cold in a suit the operator lent them. The coat was never the problem.

The temperatures you are actually dressing for
Longyearbyen averages roughly −12 °C to −16 °C from January through March, with March marginally the coldest month of the year at around −16 °C. Summer is not warm: June to August daily means sit around 2 °C to 6 °C, and July, the warmest month, averages about 4.7 °C.
Those are means, not what you feel. Wind off the fjord is the variable that matters, and on a snowmobile you are generating your own wind chill at every speed. Dress for the still-air number minus a lot.
The second thing to know is that standing still is the problem, not moving. Every tour here has long stationary stretches — waiting for a fox, waiting for the aurora to build, standing at the Seed Vault entrance for photographs. Layers you can add when you stop matter more than a single warm garment.
What operators give you, by tour
This varies more than you would expect, and it changes what you need to pack.
| Tour | Provided | You bring |
|---|---|---|
| Ice cave by snowmobile | Snowmobile suit, helmet, protective gear | All base and mid layers, warm socks, goggles |
| Pyramiden boat day | Drysuit, safety equipment | Thermals, mid layers, hat, scarf, warm shoes |
| Gruve 3 coal mine | Overall, helmet, headlamp | Warm layers, sturdy closed shoes |
| Wildlife safari | Ice spikes, headlamp when needed | Everything else — hat, gloves, warm and waterproof boots |
| Northern lights photography | Nothing but transport and the van | All clothing, plus camera and tripod |
The wildlife safari’s exclusion list is unusually blunt: warm clothing, boots, hat, mittens and gloves are explicitly not included. That tour runs up to three hours outdoors, sometimes in wind and rain, and does not cancel for weather. It is the one to over-pack for.
The winter list
Base layer. Merino wool or a synthetic, top and bottom. Not cotton — cotton holds sweat against your skin and then chills you the moment you stop moving, which on a wildlife tour is most of the day.
Mid layer. Fleece or a light down sweater. On the coldest days, two.
Outer layer. For tours that provide a suit, a normal windproof jacket to travel in is enough. For the mine tour and town tours, which provide only an overall or nothing, bring a proper insulated winter coat.
Extremities, which is where people actually suffer. A hat that covers your ears. Two pairs of gloves — thin liners you can keep on to work a camera, and heavy mittens over them. Warm wool socks, one pair, not three (three pairs compress your boots and cut circulation, which makes your feet colder).
Boots. Insulated and roomy. If yours are borderline, Longyearbyen has outfitters that rent proper winter boots by the day, and it is worth the money on a four-hour tour.
Goggles or sunglasses. Non-negotiable on a snowmobile, and useful in March and April when sun on snow is genuinely dazzling.
The summer list
Shorter, but less obvious.
Waterproof boots, not warm ones. The ground from May to September is frequently wet, and the wildlife safari’s own equipment note says waterproof hiking boots are necessary in those months. Wet feet at 4 °C ruin a five-hour tour faster than cold air does.
Layers, still. A base layer, a fleece and a windproof shell. You will take the fleece off walking and put it straight back on when the group stops.
A hat and gloves in July. Yes, really. On the water, in a drysuit, at 4 °C with the boat moving, bare hands stop working.
An eye mask. Not a tour item, but the midnight sun runs to around 22 August and hotel curtains are inconsistent.
Sunscreen. 24-hour sun off snow and water burns people who did not think Svalbard was a place you could get burnt.
Cameras, and the thing nobody tells you
Cold kills batteries. Not slowly — a camera that shows two-thirds charge indoors can die in twenty minutes at −15 °C. Carry spares in an inside pocket against your body and swap them as they fade; the dead ones usually recover once they warm up.
Bring a lens cloth and accept that condensation is coming. When you get back into a warm van with a cold camera, moisture forms on and inside the lens. The professional habit is to put the camera in a sealed bag before going indoors and let it warm up in there.
Both photography tours here — the aurora night and the wildlife safari — expect you to bring your own body, lens and tripod. Neither provides equipment; what they provide is a guide who will set it up with you.
What you can leave at home
Ski goggles if you are not snowmobiling. A giant expedition parka if every tour you have booked provides a suit — it takes up half a bag and you will wear it between the hotel and the van. Hiking poles, which nobody uses on these routes. And formal anything: Longyearbyen is a town where people wear their outdoor kit to dinner.
Frequently Asked Questions
How cold does Svalbard get in winter?
Longyearbyen’s monthly means run about −12 °C to −16 °C from January to March, with March the coldest at around −16 °C. Individual days go considerably lower, and wind chill makes a much bigger difference to how it feels than the number itself.
Can I rent warm clothing in Longyearbyen?
Yes. Several operators and outfitters in town rent winter boots, snowsuits and mittens by the day, which is worth doing if you have flown in with borderline kit rather than buying a full winter wardrobe for one trip. Tour operators themselves provide the outer suit for snowmobile and boat tours but not the layers underneath.
What should I wear on a Svalbard boat tour?
Thermals, a fleece, warm socks, a hat and a scarf — all under the drysuit the operator provides. The drysuit keeps water and wind out; it does not keep you warm on its own. Warm shoes matter because you will be standing on deck.
Do I need special clothing for the coal mine tour?
Just warm layers and closed shoes you do not mind getting dusty. The mine sits a few degrees above freezing year-round, so it is cold even in July, and the operator gives you an overall, helmet and headlamp at the surface.
Is cotton really that bad?
Yes. Cotton absorbs sweat, holds it, and then draws heat out of you when you stop moving. On a tour that alternates between walking and standing still for twenty minutes waiting for wildlife, that cycle repeats all day. Merino or synthetic base layers do the opposite.
Stand at the Door of the Global Seed Vault
Two hours by car to the concrete wedge in the mountainside, out through Adventdalen where the reindeer graze, and round Longyearbyen's mining heritage. Hotel pickup and a warm drink included — and it runs every month of the year.
