Packing Guide — Iceland in December
What to Pack for Iceland in December
Last updated: September 2026
December Iceland is not defined by cold — the thermometer usually sits around a manageable 28–38°F (-2 to 3°C). It's defined by three things that number hides: wind, ice, and just four to five hours of daylight. Pack for those three realities and December rewards you with peak northern-lights nights, steaming hot springs in the dark, Christmas lights across Reykjavik, and its famous New Year's fireworks. This guide covers what to bring, what to skip, and how to fit it all in a bag.

Quick Answer
What Should I Pack for Iceland in December?
Build around a three-part layering system: moisture-wicking base layers (tops and bottoms), an insulating mid layer, and a fully windproof + waterproof shell. Add waterproof boots, slip-on ice traction, warm accessories that cover head, hands, and neck, and a hot-spring kit. Carry-on (40–48L) is achievable for disciplined packers who wear their bulk on the plane; travelers with tripods, camera gear, or bulkier boots should plan on checked luggage.

Conditions
Wind, Ice, and Darkness: What December Actually Means in Iceland
Wind is the layer you can't see on a weather app. Icelandic wind on exposed coastline and at waterfall viewpoints is strong enough to make umbrellas genuinely useless — nobody uses them — and it drives rain and sleet horizontally. This is why the shell matters more than the parka: a windproof, hooded, waterproof outer layer over insulation handles conditions a heavy coat alone cannot. Wind chill routinely makes a 34°F afternoon feel far colder, especially standing still at viewpoints.
Ice is a freeze-thaw problem, not a snow problem. December flips between rain, sleet, and frost, which means walking surfaces melt by day and refreeze overnight. Sidewalks in Reykjavik, parking lots, and the spray zones around waterfalls can be sheet ice while the roads nearby are clear. This is the condition most first-time December visitors don't pack for — and it's why slip-on traction earns its place in the bag while a second pair of jeans doesn't.
Daylight is a planning constraint, not just a mood. You get only about 5 hours of usable light at the start of December, shrinking to roughly 4 around the solstice — the sun rises near 11am and sets by about 3:30pm. Many travelers drive in the dark at both ends of the day, and popular stops effectively close themselves by mid-afternoon. The packing consequences are small but real: a headlamp stops being camping gear and becomes how you find the trailhead, and battery drain from cold plus constant photo-taking makes a power bank non-negotiable. The upside of all that darkness is the entire reason many December travelers come: aurora season is fully open.
Strategy
The Wet-Cold Layering System (and Why a Big Parka Underperforms)
Iceland in December is wet-cold — hovering around freezing with rain, sleet, and spray — which is harder to dress for than dry deep-cold. The system that works is three independent layers: a moisture-wicking base (merino or synthetic — never cotton, which stays wet and cold against your skin), an insulating mid layer (a 200-weight fleece or a light packable down jacket), and a windproof, waterproof, hooded shell sized to fit over the mid layer.
The reason this beats a single heavy parka for packing: December days swing between 25°F wind-chill viewpoints and heated cars, museums, and cafes. A layering system lets you shed and add insulation a dozen times a day, and it compresses into roughly half the volume of a bulky winter coat — often the single decision that determines whether carry-on-only is possible. Travelers who run cold can carry both a fleece and a packable down layer and still come out ahead on volume.
That said — if you already own a warm, waterproof winter jacket, bringing it is a perfectly reasonable choice. Plenty of December visitors wear their everyday winter coat the entire trip and are comfortable, especially on city-based itineraries built around Reykjavik and guided day tours. The tradeoffs are packing volume (wear it on the plane, don't pack it) and less flexibility when the day swings between outdoor viewpoints and heated indoor stops. If your jacket is warm but not waterproof, pair it with a packable rain shell that fits over it. The layering system is the packing-efficient route, not the only correct one.
Packing Optimization
Reduce Volume Before You Calculate
Compression packing cubes reduce clothing volume by 20–30% — and December Iceland's fleece, base layers, and wool socks are exactly the soft, lofty items compression works best on.

This estimate reflects your core packing setup. For December Iceland, also account for ~5–8L of small extras — microspikes, headlamp, swimsuit and quick-dry towel, insulated gloves and hand warmers, beanie, and a power bank — and subtract what you wear on the plane: boots and the shell system move 8–10L out of the bag.
Essentials
Iceland in December Packing List
Base Layers
2–3 thermal base tops + 2 base layer bottoms
Merino or synthetic only — cotton stays wet against your skin in Iceland's rain-sleet mix. Base bottoms go under pants for viewpoint days and aurora watching; you'll wear them more than you expect.
Mid Layer
1–2 insulating mid layers (200-weight fleece and/or packable down)
The fleece is the daily workhorse; a packable down layer adds warmth for aurora nights at minimal volume. Both together still pack smaller than one heavy parka.
Shell
1 windproof + waterproof hooded shell
The single most important item in the bag. Fully waterproof and genuinely windproof, seam-sealed, with a hood that cinches — the shell is your entire rain plan. Must fit over the mid layer.
Packable Rain Shells
Waterproof and seam-sealed — December precipitation arrives as wind-driven rain and sleet, not gentle showers.
Everyday Clothing
3–4 long-sleeve tops + 2–3 pants (1 water-resistant)
All long sleeves — layering pieces, not standalone outfits. At least one pair of pants should be water-resistant softshell or hiking material; jeans soak through in spray and wind-driven rain and stay wet for hours.
Wool Socks
5–6 pairs wool or wool-blend socks
Wool keeps insulating when damp — and in December Iceland, your feet will get damp. Bring one pair more than the math says; wet boots and a heated floor at the guesthouse make the spare pair the best few ounces in the bag.
Footwear + Traction
1 worn pair of waterproof boots + 1 pair slip-on microspikes / ice cleats
Waterproof boots with real tread, worn on the plane — never packed. Slip-on traction is the item first-timers skip and regret; it solves the viewpoint ice problem for very little weight or volume. An optional compact second pair of shoes covers dinners and flights.
Head, Hands & Neck
Warm beanie + insulated gloves (consider liner gloves) + wool buff, scarf, or balaclava + a few hand warmers
Wind chill makes exposed skin the limiting factor on how long you can stand at a viewpoint. Liner gloves under insulated gloves let you work a camera without going bare-handed; a buff or balaclava seals the gap a scarf leaves in real wind. Disposable hand warmers are cheap insurance for aurora nights and dark early-morning starts in December's deeper cold.
Hot Spring Kit
1 swimsuit + 1 quick-dry towel + small dry bag or zip pouch
The December paradox: you will swim on this trip. Lagoons and local pools run all winter and are best in the cold and dark. Major lagoons rent or include towels, but a quick-dry towel covers municipal pools and budget springs — and the dry bag keeps a wet suit from soaking everything else in the car.
Light & Power
Headlamp + power bank + chargers (Iceland uses EU plugs)
With only about 4–5 hours of daylight, a headlamp is how you reach trailheads and read hot-spring signs after dark — a phone flashlight ties up the hand you need. Cold drains batteries 20–30% faster; keep the power bank in an inside pocket. US travelers need EU (Type C/F) plug adapters.
Northern Lights & Camera Notes
Phone tripod or camera setup (optional) + the warm layers you already packed
Aurora watching is standing still in wind at night — it's the coldest thing you'll do, and the reason the down layer and balaclava earn their space. Modern phones capture aurora surprisingly well from a small tripod; a full camera + tripod kit adds 4–8L and is the most common single reason December travelers end up checking a bag. Decide deliberately.
Daypack
Compact daypack (13–20L)
Lives in the car or on your back: shell, traction, water, snacks, headlamp, and the layer you just shed. Water-resistant fabric earns its keep in spray zones.
Packable Daypacks
Sized for the December layer shuffle — shell + fleece + traction + headlamp.
Toiletries & Small Stuff
Standard travel kit + lip balm + moisturizer + sunglasses
Wind and cold dry skin fast — lip balm and moisturizer are daily-use items, not extras. Sunglasses matter more than you'd think: December sun never gets far above the horizon, so when it's out, it's in your eyes on every drive.
Documents & Practical
Passport, license (if driving), reservation confirmations, credit card
Iceland is nearly cashless — cards work everywhere, including rural gas pumps (a PIN-enabled card helps). If you're renting a car, confirm winter tires are included (standard in December) and build daylight hours into your driving plan.

Volume
How Much Space Does a December Iceland Trip Require?
~40–52L
Typical packing volume for a 7-day December Iceland trip
Light packers / strict layering, bulk worn on plane
~36–42L
Standard packers / full system + hot spring kit
~42–50L
Heavy packers / extra layers, second boots
~48–58L
Camera + tripod / aurora photography kit
~52–64L
What you wear on the plane matters more here than on almost any other trip type: boots, base layer, fleece, and shell worn rather than packed remove 8–10L from the bag. That single habit — plus compression cubes on the lofty layers — is what keeps disciplined December setups inside carry-on range. Many travelers will still prefer a checked bag for a trip this gear-heavy, and that's a reasonable call, not a failure.
Constraints
What Changes the Math
- Packing a heavy winter jacket instead of wearing it — a packed parka consumes 6–10L; worn on the plane it costs nothing, and if it isn't waterproof, add a packable shell over it
- Packing boots instead of wearing them — waterproof boots are 4–6L of rigid volume; on your feet they're zero
- Camera body + lenses + full tripod — the most common single reason December Iceland travelers check a bag; adds 4–8L of rigid, fragile volume
- Jeans as primary pants — soak through in spray and stay wet; one water-resistant pair replaces two packed jeans
- Skipping base layer bottoms — the item whose absence you feel at every viewpoint after 3pm
- Cotton anything as a base layer — wet cotton at 32°F in wind is a genuine safety issue, not just discomfort
- A third pair of shoes — boots worn + one compact pair covers essentially every December itinerary
- One dressier holiday or New Year's outfit — a single warm-but-nicer layer covers it; a full formal kit is volume you won't use
- Full-size towel instead of quick-dry — bath towels are 2–3L and dry slowly in a December guesthouse
- Not pre-deciding the aurora photography question — the tripod decision determines your bag class more than any clothing choice
Gear
Best Bag Size for Iceland in December
Light / disciplined layering, bulk worn
40–42L
Compression cubes + strict shoe discipline required
Most December trips (standard)
42–46L
Full layering system, hot spring kit, one extra pair of shoes
Camera gear / extra boots / more variety
45L+
At or above carry-on ceiling — checked bag likely, and reasonable
A 42–46L bag is the realistic sweet spot for carry-on-focused December travelers — big enough for the layering system and hot-spring kit without demanding perfect packing. Most US visitors reach Iceland on Icelandair or PLAY: Icelandair includes a 55 × 40 × 20 cm cabin bag plus a personal item on standard fares, while PLAY's free allowance is tighter and its bag sizers are strict — verify your bag against your airline's specific limits with the Airline Bag Size Checker before assuming it flies free.

Common Questions
Iceland in December Packing FAQ
How many hours of daylight does Iceland have in December?
Around the solstice, Reykjavik gets only about 4–5 hours of usable daylight — sunrise near 11:10am, sunset around 3:30pm, and shortest in the third week of December. You sightsee in a short midday window and drive in the dark at both ends, so a headlamp, a power bank, and a realistic daily plan matter more than in any other month. The upside of all that darkness: long, prime aurora nights.
Can you see the northern lights in Iceland in December?
December is one of the best months to try — the long dark nights give the aurora a wide viewing window. Nothing is guaranteed (it's unpredictable, and Iceland is often cloudy), but the odds are as good as any winter month. Pack for standing still in the cold: the insulated mid layer, a balaclava or buff, insulated gloves, and hand warmers earn their place, and a small tripod helps a phone or camera capture it.
What should I pack for Iceland at Christmas and New Year's?
The same winter layering system, plus one dressier-but-warm option for a holiday dinner or Reykjavik's New Year's Eve. New Year's here means community bonfires and one of the biggest public fireworks displays anywhere — a cold night outdoors, so warm layers, waterproof boots, and gloves matter more than anything formal. Some shops and attractions keep reduced hours or close December 24–26 and January 1, so pack a few snacks and confirm times.
Bottom Line
- Pack for wind, ice, and only ~4–5 hours of daylight — not just cold; the thermometer is the least of December's problems
- The base + mid + shell layering system beats a heavy parka on warmth flexibility and packs into half the volume
- Microspikes are the item first-timers skip and regret — freeze-thaw ice at viewpoints is December's signature hazard
- No cotton base layers, no jeans as primary pants, no umbrella — Icelandic wind and wet-cold punish all three
- Pack the swimsuit: hot springs and lagoons are a December highlight, best in the cold and dark
- Over the holidays, add one warm-but-dressier layer for New Year's — Reykjavik's fireworks are a cold night outside, not a formal event
- Wear boots, base, fleece, and shell on the plane — that habit alone moves 8–10L out of your bag
- Efficient setups run 40–52L; carry-on is achievable with discipline, and checking a bag is a reasonable choice for a trip this gear-heavy
- The tripod decision determines your bag class more than any clothing choice — make it before you pack
Notes
How Accurate Is This?
Volume estimates are based on real clothing measurements, standard packing behavior, and a 15% gap factor for dead space inside the bag. Results vary by bag design, clothing thickness, and how tightly you pack.
The calculator uses the same engine as the rest of the site — it accounts for climate, packing style, laundry access, shoes, laptop, and bulky layers. Selecting "Cold" climate with the bulky layer toggle reflects December Iceland's typical demands.
Iceland-specific items — microspikes, headlamp, hot-spring kit, and aurora photography gear — are addressed in the editorial content but not individually modeled by the calculator; the helper note under your result covers how to adjust for them.
Temperature and daylight figures reflect typical December conditions in Reykjavik and along the south coast, where most first-time December itineraries concentrate. The north and interior run colder; conditions vary year to year, and Icelandic weather changes fast enough that locals check forecasts daily — build flexibility into both your packing and your driving plan.
