What to wear in Iceland in winter: the packing list
Reykjavik averages about 0.5C in January and the wind does the damage, not the number. Here is the layering system, the jeans problem, and what operators already supply.
Written with Björn Einarsson, Icelandic guide & winter tour specialist
Sleet in Iceland does not fall so much as travel sideways, and the first place it finds is the gap between a glove and a sleeve. I have watched a visitor step off the coach at Skógafoss in a beautiful wool coat, last about four minutes in the spray, and spend the rest of the stop sitting in the bus with the heater on. The coat was not cheap. It was just the wrong material, worn over the wrong trousers, in the wrong wind.
TL;DR. Three layers, and the outer one has to stop wind and water. No cotton anywhere, and jeans least of all. Boots with deep tread, a hat that covers your ears, waterproof gloves plus a thin spare pair, and something over your face for the aurora stops. Leave the umbrella at home. Do not buy crampons, a helmet or a drysuit: the glacier, ice cave and Silfra operators issue those on the day, and the whale boats hand out thermal overalls at the gangway.
What should you actually wear in Iceland in winter?
Wear three layers: a wool or synthetic base against the skin, a fleece or light down mid-layer for warmth, and a windproof waterproof shell over both. Add waterproof trousers, boots with real tread, a hat, a neck gaiter and gloves. The shell matters more than the thickness of anything underneath it.
The number people plan around is the temperature, and it misleads them. Reykjavík sits at about 0.5°C on average in January, which sounds survivable, and on a still day it is. Then you stand on an exposed headland with a wind coming off the North Atlantic and that same 0.5°C strips heat off you faster than a dry minus ten inland would.
So the system is built against wind and water, not against cold air. The base layer's job is to move sweat away from your skin, because damp skin is cold skin. Merino wool does this well and does not start to smell after two days. Synthetic base layers work too and cost less.
The mid-layer traps warm air. A fleece, a thin down jacket, a wool jumper, any of them will do, and on a mild February day you may take it off between stops.
The shell is the layer that decides whether the trip is pleasant. It has to be genuinely waterproof rather than water-resistant, and it has to have a hood that stays up in wind. A hood that blows off is a hood you will hold with one hand for the entire waterfall stop.
Waterproof over-trousers are the piece most people skip and most people regret. They pack down to nothing, they go on over whatever you are already wearing, and they are the difference between enjoying Seljalandsfoss and enduring it. If you want a fuller picture of the conditions you are dressing for, the guide on what an Icelandic winter is actually like covers the weather side properly.
Why should you not wear jeans in Iceland?
Because denim is cotton, cotton soaks up water and holds it, and wet cotton pulls heat out of your legs instead of keeping it in. Jeans take hours to dry in a cold coach. On a northern lights stop you may stand still outdoors for an hour, and that is exactly when wet legs turn into a miserable night.
This is the single most common mistake I see, and it is worth explaining properly rather than just repeating the rule. Wool and synthetics keep some insulating value when damp, because their fibres still trap air. Cotton does not. Once denim is wet, the fibres collapse together, water fills the gaps, and water conducts heat away from your skin many times faster than air does. Your legs then heat the wet fabric instead of heating you.
Two Icelandic situations make this worse than it sounds. The first is waterfall spray. Seljalandsfoss throws mist a long way in the right wind, and Skógafoss will soak you at the base without any rain falling at all. The second is standing still. A northern lights stop is not a walk. You get off the coach in a dark car park or a farm track, you stand, you wait, and you keep waiting because the display might build. An hour of standing still in wet denim in a cold wind is genuinely unpleasant and, in the worst cases, a real safety issue.
The fix costs nothing complicated. Thermal leggings under fleece-lined trousers or hiking trousers, waterproof over-trousers on top when it is wet, and the jeans stay in the suitcase for the evening in Reykjavík. I have written more about why this rule became such an obsession among Icelandic guides in why nobody wears jeans in Iceland.
What kind of coat is best for an Icelandic winter?
A waterproof, windproof shell with a proper hood, worn over an insulating mid-layer. A big untreated down parka is warm but useless once wet, and a fashion wool coat is worse. If you own only one coat, make it a hardshell and add warmth underneath rather than buying a thicker single jacket.
Coats are where the money goes and where the mistakes get expensive, so it helps to think about what each type actually does in Icelandic conditions rather than what it says on the label.
| Coat type | How it copes with Icelandic winter | Verdict |
|---|---|---|
| Hardshell (waterproof, windproof, uninsulated) | Stops the wind and the rain completely, no warmth of its own | The right choice, layered over fleece or down |
| Insulated waterproof parka | Shell and warmth in one, bulkier, harder to regulate on a warm coach | Excellent if you own one, run it with a thin base layer |
| Untreated down puffer | Very warm dry, loses most of its loft once soaked | Fine as a mid-layer under a shell, poor as an outer layer |
| Softshell | Blocks wind, sheds drizzle, gives up in real rain | Acceptable for Reykjavík, not for a South Coast waterfall stop |
| Wool overcoat | Looks the part, wets through, catches the wind | Evening wear in the city and nothing else |
| Ski jacket | Built for exactly this, waterproof and insulated | Bring the one you already own, no need to buy anything new |
Two details separate a good shell from a frustrating one. The hood needs a stiffened peak and a real adjustment, so it holds shape and stays put in wind. And the cuffs need to close, because the standard failure point is water running down a sleeve while you hold a camera up.
If you are working out whether to buy gear or borrow it, the honest arithmetic is in what an Iceland winter trip costs: a shell you will use again is worth buying, a one-week novelty is not.
How should you layer for each type of winter tour?
The base and mid layers barely change. What changes is the outer layer and the extras: a whale boat needs wind protection above all, a glacier hike needs stiff boots and gaiters, an aurora night needs standing-still warmth, and a Blue Lagoon trip mostly needs flip-flops and a plan for wet hair.
Different days ask different things of the same wardrobe, which is why a single packing list annoys people. Here is how the same three layers get deployed.
| Tour type | Base | Mid | Outer and extras |
|---|---|---|---|
| South Coast day tour | Wool base top and leggings | Fleece | Waterproof shell and over-trousers, boots with tread, hat, gloves |
| Northern lights hunt | Wool base, thickest you own | Down or heavy fleece | Shell, over-trousers, thick socks, face gaiter, hand warmers |
| Glacier hike | Wool base | Fleece | Shell, stiff-soled walking boots, gaiters if you have them, sunglasses |
| Ice cave trip | Wool base | Fleece | Shell, waterproof boots, gloves you can grip with, headtorch optional |
| Whale watching | Wool base | Fleece | Windproof shell under the boat's overalls, hat that will not blow off |
| Snowmobiling | Wool base | Fleece | Operator suit over everything, goggles or sunglasses, thin liner gloves |
| Silfra snorkel | Thin thermal base | Provided | Drysuit undersuit provided, bring warm dry clothes for afterwards |
| Golden Circle | Wool base | Fleece | Shell, boots with grip for the Gullfoss path in ice |
| Blue Lagoon | Whatever you are travelling in | Any | Swimsuit, flip-flops, hair conditioner, warm hat for the walk out |
Footwear deserves its own note, because it is the item people most often get wrong after the trousers. You want boots with deep, widely spaced tread and enough ankle support to walk a frozen car park confidently. Reykjavík pavements ice over, and the Gullfoss viewing steps in January are their own small adventure. Slip-on ice grips that stretch over a boot sole cost very little, weigh nothing and turn a nervous walk into an ordinary one. They are not the same as crampons, and you do not need crampons: those come with the glacier trip.
What do the tour operators already give you?
Quite a lot, and packing duplicates of it wastes suitcase space. Glacier operators supply crampons, a harness and a helmet. Ice cave tours add the helmet and headtorch. Silfra includes the drysuit, hood and gloves. Whale boats lend thermal overalls. Snowmobile operators provide the suit, gloves, helmet and boots.
The rule of thumb: anything specialised and safety-related is issued at the meeting point, because the operator's own insurance depends on the fit and condition of it. Anything ordinary is yours to bring.
| Tour type | The operator supplies | You bring |
|---|---|---|
| Glacier hiking | Crampons, harness, ice axe, helmet | Stiff walking boots, layers, waterproofs, gloves |
| Ice cave | Crampons, helmet, headtorch | Waterproof boots, warm layers, gloves |
| Snowmobiling | Overall, helmet, balaclava, gloves, boots | Base layers, goggles or sunglasses, thin liner gloves |
| Silfra snorkelling | Drysuit, undersuit, hood, neoprene gloves, mask | Thermal base layer, warm dry clothes and a towel for after |
| Whale watching | Thermal overall on board | Windproof outer layer, hat, gloves, seasickness tablets |
| Northern lights bus | Nothing but the coach and the hot drink | Everything, this is the coldest standing you will do |
| South Coast and Golden Circle | Coach and guide only | Full three layers, boots, ice grips |
That last row is the one to read twice. A northern lights coach gives you a warm seat and a cup of cocoa, and then it puts you outside in the dark at whatever spot has the clearest sky. The tour itself does nothing to keep you warm. If you want a sense of how those nights run before you dress for one, what a northern lights tour is actually like walks through a real one, and the northern lights tours page lays out which departures include a free retry night.
What should you leave at home?
Umbrellas, jeans, fashion boots with smooth soles, heavy hiking gear you will never use, and any specialised safety kit the operator issues anyway. Also skip the giant suitcase: most winter day tours pick up from a Reykjavík hotel or bus stop and you will be living out of one bag for a week.
Umbrellas are the comic one. They invert on the first gust and then you carry a broken metal thing all day. A hood does the same job and cannot be destroyed by weather.
Smooth-soled boots, including most fashion and city boots, are the practical hazard. Icelandic towns grit the main routes but car parks and paths at the sights are frequently glazed, and a fall on ice ends trips. If your boots are stylish and slick, buy the stretch-on ice grips before you go rather than paying Reykjavík prices for them.
Then there is the over-packing category: crampons bought online, a climbing helmet, a full snow suit for a city break, a tripod you will use once. The gear the tours require comes with the tours. What genuinely does not come with them is a second pair of gloves, and I would put that near the top of any list. Gloves get wet, and a wet pair on a five-hour drive stays wet.
Two things worth checking rather than packing. Road conditions on the morning of any drive at road.is, which is what every Icelandic guide has open at breakfast, and the official safety channel safetravel.is, where you can leave a travel plan and pick up the 112 Iceland app. Neither weighs anything.
What small items make the biggest difference on a tour day?
A spare pair of gloves, a face gaiter, hand warmers, thick wool socks, a headtorch, a power bank and a refillable water bottle. None of them are expensive and each one solves a problem that otherwise sits with you for eight hours in a coach.
Cold hands ruin more winter days than cold feet. You take gloves off to work a camera, they get wet, and there is nowhere on a coach to dry them. Carry a thin liner pair inside the waterproof outer pair and you can shoot photographs without going bare-handed.
A neck gaiter you can pull up over your nose is the cheapest comfort upgrade in Iceland. On an aurora stop the wind is doing the work, and covering the face changes the experience completely.
Battery life is the other quiet problem. Cold flattens phone batteries fast, and your phone is your camera, your map and your pickup confirmation. Keep it in an inside pocket against your body and carry a power bank.
Wool socks, two thicknesses, and a proper water bottle. Icelandic tap water is excellent and free, so buying bottled here is money set on fire.
If you are pointing all this at one trip in particular, the South Coast is the day that tests every layer you own: waterfall spray, black sand wind at Reynisfjara, and a glacier edge in the same outing. The South Coast tours page compares the real departures, and the most-reviewed of them, BusTravel Iceland's 10 to 12 hour run at 4.8 across 12,306 GetYourGuide reviews, is available to check for your dates on GetYourGuide.
For everything else people ask before they book, our FAQ answers the pickup, cancellation and weather questions in one place. And if you are still deciding whether to hire a car and dress for your own driving instead, self-drive versus guided tours in winter is the honest comparison, because a driver needs different gear again: a scraper, a spare pair of dry gloves in the boot, and the patience to turn back.
