Campervan in Iceland in December

Reykjavík opens December with 5 h 02 min of sun and closes it with 4 h 20 min. In between, the curve flattens out completely: 4 h 07 min on the 21st, sunrise 11:22 and sunset 15:29, and the same two clock times on every day from the 18th to the 24th. That works out at a loss of about a minute and a half a day.

Plan against civil twilight rather than against the sun. On the shortest day Reykjavík has 6 h 46 min between the light coming up and going out — two hours thirty-nine more than the sun spends above the horizon — and that wider block is what you can actually drive, walk and pitch up in. On 1 December it is 7 h 23 min, so the first week carries about thirty-seven minutes more workable light a day than the solstice week: real, and nowhere near enough to redesign a trip around.

The north is a different month again. Akureyri's shortest day is 3 h 04 min, 11:39 to 14:42, with 6 h 16 min of civil light around it, and the town gives up fifty-three minutes across December, a dozen more than the capital. An afternoon up there in solstice week is finished before three. Akureyri also sits nearly four degrees further east, which puts its solar noon about a quarter of an hour earlier than Reykjavík's — around 13:10 against roughly 13:25 — so the usable block sits earlier in the clock day, not later, the opposite of what most people assume about going north.

The evening turns before the morning does. Reykjavík's sunset stops getting earlier around the middle of the month and by 31 December falls twelve minutes later than it did on the shortest day, while sunrise is still creeping later and does not turn until after the New Year. That is why 31 December has thirteen more minutes of sun than the shortest day does, despite sitting deeper into the dark half of the winter, and why the solstice reads in Icelandic media as a hinge rather than a low point.

The other side of the ledger is why a lot of people book this month at all. On 15 December Reykjavík gets 12 h 53 min of true astronomical darkness, from 18:56 to 07:50, and Akureyri 13 h 02 min. Darkness that opens before seven in the evening is a very different night from darkness that opens near midnight.

The first three weeks are an ordinary Icelandic winter with decorations on, and shops keep normal hours. The Christmas market on Austurvöllur opens with the lighting of the Oslo tree on the first Sunday of Advent — the fourth Sunday before Christmas Day, so a moveable date in the last days of November or the first of December — and the Christmas Valley in Laugardalur runs weekend evening hours from about the same point. Oslo has given Reykjavík a spruce every year since 1951, though since 2015 the tree has been cut in the city's own woodland at Heiðmörk and Oslo sends books to schoolchildren instead.

The folklore runs to a timetable too, which is why an Icelandic December is counted in nights. Thirteen Yule Lads — Jólasveinarnir, sons of the ogress Grýla, mountain trolls rather than one red-suited saint — come down one per night, the first on the night of 11 December and the last, Kertasníkir the Candle-Stealer, on the night of Þorláksmessa. The gift appears in the shoe on the windowsill the next morning, which is why half the sources date the start to the 11th and half to the 12th; a badly behaved child gets a raw potato. Each stays thirteen nights and they leave in the order they came, so the last of them is still about well into the New Year — the January guide has the night that ends it. Their names and their order were fixed by a poem published in 1932, and the names are the joke: Þvörusleikir licks the spoon, Bjúgnakrækir takes the sausages, Gluggagægir looks in at the window.

From the evening of the 23rd the country changes gear and does not change back until the 2nd. Two of those days are full statutory holidays, two more are legal half-days, and the week between them is quiet rather than closed. For a traveller in a vehicle with a small fridge and no shower, that ten-day block is the single most consequential thing about the month, and all of it is knowable in advance.

It costs money too, and the pressure sits in the same ten days: domestic travel, a specific kind of visitor chasing an unusual Christmas, and a fleet that cannot grow to meet a one-week surge. Those ten days are the tightest camper availability we measure outside high summer; the rest of December is not, and the two halves of the month should be booked as if they were different seasons. Be sceptical of any figure you are handed for the size of the holiday premium — no Icelandic statistical release publishes one, and the percentages in circulation come from car-rental blogs rather than from Ferðamálastofa or Statistics Iceland.

The practical conclusion is unusually clean for a country this changeable. If the holidays are not the point of the trip, the first ten days carry the best value and the most daylight in the month. If they are the point, book early, accept the price, and build the itinerary around what is open rather than around what you wanted to see.

Two separate laws do the work and they are routinely conflated. The forty-hour-week act of 1971 grants paid time off from 13:00 on both 24 and 31 December, which is why those two days are half-days for almost everyone who works. The holiday peace act of 1997 is a different instrument: it protects religious observance, and under it Christmas Eve becomes a protected day from 18:00, three hours after the labour-law cutoff. A 2019 amendment relaxed most of the commercial restrictions in the older version of that act, so what you meet on the ground is now practice rather than prohibition — which is why it varies by chain and by branch and has to be checked rather than assumed.

The rhythm underneath is a single evening. Þorláksmessa on the 23rd is the last full trading day and the loudest one: the feast of Þorlákur Þórhallsson, twelfth-century bishop of Skálholt and Iceland's only canonised saint, eaten with kæst skata, fermented skate, by something like a third of Icelanders. The smell is the point, and restaurants that serve it ventilate accordingly. Shops trade late, with the state alcohol chain's capital-area stores open to 22:00. Then on the 24th the country empties out through the afternoon, and at 18:00 the national broadcaster's church bells mark the start of Christmas, at which point almost every Icelander is sitting down to dinner.

The 25th is quieter still. Icelandic accounts consistently describe Christmas Day, not Christmas Eve, as the quietest day of the year — which is not how it works in most of the countries visitors fly in from, and it catches people out. What follows is the pattern the chains re-post each December with small variations, not a fixed rule: treat the clock times as a shape to plan around, and check the branch you are actually relying on.

Fuel first, because it is the one people worry about. Iceland's network is built around unattended, card-only self-service pumps that sit physically separate from any staffed shop on the same forecourt — the Icelandic press has a standing phrase for it, open around the clock with nobody on shift. One operator runs twenty-five stations on that model every day of the year. What closes on Christmas Day is the coffee, the hot dogs, the toilet and the till, not the fuel.

Ploughing does not stop either, but it runs on a holiday clock. The road authority publishes a snow-clearing plan each December: clearing runs 10:00 to 16:00 on Christmas Day and 10:00 to 18:00 on New Year's Day, the 26th reverts to ordinary weekend service, and on Christmas Eve afternoon normal service continues in the capital region, on the south coast and on Reykjanes while it is trimmed elsewhere. The 1777 traffic-information line is answered 07:30 to 22:00 on both of the most closed days of the year — half an hour later to open than the road map's standing winter reporting window, and closing at the same time as it.

The swimming pools are a campervan's bathroom in this country, and they behave better than you would expect. Reykjavík's own pool timetable has no separate winter table at all: the pools run essentially the same hours in December as in July, and the only changes anywhere in the year are for named holidays. What the named holidays do to them is in the table below.

The rest is a skeleton rather than a shutdown. Keflavík Airport operates every day of the year including Christmas Day, though individual airlines trim frequencies in a way nobody publishes usefully. A handful of pharmacies stay open through the 25th, several in the capital until late in the evening, and the 10-11 convenience chain trades on its usual extended model throughout. City buses do not run one holiday timetable but two: Christmas Eve is a Saturday-level service with extra morning trips and last departures around three in the afternoon, while the 25th, the 26th and 1 January drop to Sunday level — worth knowing if the plan involves leaving the van somewhere and taking a bus into town.

New Year's Eve here runs to a nationwide timetable that almost nobody writes down for visitors. From about half past eight, neighbourhood bonfires are lit — Reykjavík alone ran ten of them in 2025, one starting at nine rather than half past eight — a tradition more than two centuries old, with speeches and community singing rather than anything staged for tourists. Fireworks are not permitted at the bonfire sites themselves, which is worth knowing if you have driven to one expecting both at once.

By about ten the bonfires empty and the country goes indoors to eat. From 22:30 to roughly 23:30 the state broadcaster shows Áramótaskaupið, an hour-long satirical review of the year that 81 per cent of the nation watched in 2023 — the highest-rated programme of any kind, in any year, in Iceland. The streets genuinely empty for that hour. If you want a photograph of Reykjavík with nobody in it, that is the window.

The fireworks proper begin the moment the Skaup ends and build to a synchronised midnight peak usually described as running thirty to forty-five minutes. There is no central display and no organising authority: individuals and families fire from gardens, streets and car parks in every direction at once, which is why the vantage points people name are simply high ground — Hallgrímskirkja and Perlan in the capital. Figures of around six hundred tonnes sold nationally in 2015, and nearer seven hundred in later estimates, are widely quoted, but they trace to travel journalism rather than to any official register, so treat the tonnage as an order of magnitude.

The mechanism behind it is the genuinely distinctive part. Almost every firework sold in Iceland is sold by Landsbjörg, the volunteer search-and-rescue association, through roughly ninety local teams and something like a hundred and twenty sales points, as its principal annual fundraiser; takings in one reported season reached up to ISK 800 million. The same teams that would come out for a camper on its roof in a crosswind are substantially funded by the fireworks the public sets off in the same week. The share of the organisation's income this represents is not published, and the funding model has itself been publicly debated.

Which leads to the least romantic paragraph here. Emergency services are stretched across the holiday: capital-region ambulance crews were reported handling well over a hundred callouts per shift over one Christmas period, and fire crews described the twenty-four hours after Christmas as a spike rather than a lull. Help is not less likely to come, but it may take longer to arrive, and a drive you would not have made in February is not a better idea on 27 December.

The normals undersell the reputation and oversell the calm. Reykjavík's 1991–2020 December mean is 0.8°C, with a mean daily maximum of 3.3 and a minimum of −1.6. There are 5.7 days in an average December when the temperature never climbs above freezing and 19.5 when it drops below it overnight, 94.9 mm of precipitation across 14.6 wet days, and snow lying on the ground on 12.6 mornings. Coastal Reykjavík in December is closer to a raw, wet, windy Scottish winter than to the frozen tundra a lot of visitors arrive expecting.

The number that actually describes the month is the sunshine one. Reykjavík's December normal is 12.6 hours of sunshine for the entire month — under half an hour a day. Akureyri's is 0.3 hours, which was 0.0 in the previous thirty-year normal too, because the town sits deep in a north-facing fjord and receives almost no direct sun in December whatever the cloud is doing. The proxy station used for Egilsstaðir also records zero. Plan photography around twilight and cloudbreaks rather than around sun, and if the aurora is on the list, what the camera needs in the dark is a separate question.

Snow is a question of altitude far more than latitude. The Met Office's own 1981–2010 figures for mornings with snow on the ground put Reykjavík town at 45.4 per cent in December against 73.8 per cent in the 500 to 700 metre band above it, and Akureyri town at 64.7 per cent against 86.6 per cent in its own mountains. That band is where the passes and the highland routes sit, which is the quantitative version of the advice that lowland roads usually go and high ones usually do not.

The spread is the real story. Reykjavík's all-time December records run from 12.9°C down to −16.8°C, a range of nearly thirty degrees inside one calendar month — though the date and station behind that high could not be pinned down, so treat it as a documented extreme rather than a dated event. The national December record is better attested: 19.8°C at Seyðisfjörður on Christmas Eve 2025, a föhn warming event on the east coast, recorded in the Met Office's own annual review. Iceland's lowest air pressure ever measured, 919.7 hPa, was also a December reading, at Vestmannaeyjar on 2 December 1929, and the worst storm to reach the country since 1991 ran from 6 to 11 December 2015, with gusts to 72.6 m/s, a central pressure of 944 hPa and hurricane-force winds at thirty-three separate stations.

None of which is what most often catches a driver out. Wind dominates the warning system — across one twelve-month reporting window, 268 of 327 Met Office warnings were for wind or gusts, and no month-by-month breakdown of warning days is published at all — but the specifically December trap is a mild spell arriving just ahead of a storm. Warm days loosen slopes that would otherwise be frozen solid, and the road authority issues rockfall and road-surface warnings on exactly those days: in the week before Christmas 2025, landslide risk was flagged for Snæfellsnes and the Westfjords for that reason. A generic winter framing of ice and cold misses the mechanism completely.

Some of the companies we catalogue withdraw part of their range for the winter, one enforces a season it publishes nowhere, and one shuts its rental desk outright from 20 December to 31 January — the company you were comparing in July may not be trading over the holidays at all. None of this is announced: model pages stay up, the photography stays summery, and the booking engine quietly returns fewer results for December dates than for July ones. The panel below is counted from those engines rather than from the brochures, which is the only way the gap shows up.

The specification that decides a December night is not drivetrain. Every highland F-road is shut to every vehicle and has been since autumn, so four-wheel drive buys traction on an unploughed pitch rather than a road you could not otherwise reach. What matters more is whether the heat runs with the engine off and away from a power socket: in December the campsite you were planning to plug into may be closed, and if it is open its outdoor taps are probably off.

Sleeping in the van outside a registered site is not the grey area it is often described as, and the rule for vehicles is stricter than the rule for tents: a camper or motorhome may not be pitched outside an organised campsite or a specially marked area without the landowner's explicit permission, which nobody is realistically obtaining at nine o'clock on a December night. The open sites are therefore the itinerary rather than a preference. By one rough industry count — rental companies' own blogs rather than a register, so treat it as indicative — roughly one site in seven on the national registry is genuinely year-round, and open does not mean serviced: heated indoor plumbing tends to survive the winter and unheated outdoor taps and shower blocks do not. Þingvellir is the sharpest example and the date is a December one. Nyrðri-Leirar, the only campsite in the national park that stays open, turns its showers off on 1 December and does not turn them back on until 1 April, while the outdoor sinks are off all winter and the electricity for motorhomes stays on.

The gaps matter as much as the anchors. There is no confirmed winter campsite in Vík, so the whole stretch of Route 1 between Hveragerði and Höfn leans on Skaftafell's reduced winter operation. The Westfjords have no site we could confirm against an operator's own page. The corridor between Akureyri and Búðardalur, through Skagafjörður and Húnaflói, is functionally a gap on current evidence. And the nearest year-round site to Keflavík Airport is not beside it: the campsite six minutes from the terminal runs 1 May to 1 October only, and the one that trades all year is at Vogar, fifteen to twenty minutes away.

The Ring Road in a week is the commonest December mistake and the arithmetic is not close. Seven solstice days give you roughly forty-seven hours of usable light in the south and about forty-four across the northern half, against something like thirteen hundred kilometres of driving plus everything you stopped the van for. If two of those seven fall over Christmas, the shops are shut on both and the pools on one. And the ring's failure points sit where the day is shortest: its highest point, roughly 600 metres up at Svartfell on Möðrudalsöræfi, is out in the north-east, and it closes in the same East Iceland storms that shut Vopnafjarðarheiði and Vatnsskarð eystra.

The east is where the margin disappears altogether. Fjarðarheiði, the pass between Egilsstaðir and Seyðisfjörður, closed an average of eleven full days a year across 2010 to 2024, with about thirty separate closure incidents annually, and when it shuts the lower route through Fagridalur is almost always shut with it. You do not have to be unlucky to lose a day out there; you have to be there. A closure with a flight at the end of the week is the one weather problem that costs more than the rental did.

What works in December is short and repeatable. The south coast as an out-and-back keeps you near towns, fuel and the campsites that trade through winter, and it is the mildest and best-served corridor in the country. The Golden Circle works as a day loop from a Þingvellir or Selfoss base, with the caveat that Mosfellsheiði and Lyngdalsheiði, minutes from the capital, close in storms like anything else. Reykjanes and Snæfellsnes are two or three days each if the wind allows. Everything beyond that is a bonus you should not have booked anything against.

Route the holiday days deliberately. Be somewhere with a supermarket and a pool on the 23rd, be parked by early afternoon on the 24th with the food already bought, and treat the 25th as a walking day rather than a driving one. One documented exception on the south coast is worth planning around: in the annual media sweeps of holiday hours, the Krónan branch in Vík í Mýrdal has appeared trading 12:00 to 18:00 on both the 24th and the 25th while the rest of its chain shuts. That is a branch-level posting rather than a standing rule, so confirm it — but it is the only such window on that stretch of road.

One date sits just past the edge of the month and is worth knowing before you plan a rural leg into the New Year. The road authority funds a once-weekly plough on its lightest-served rural roads at its own cost only up to 5 January; after that, weekly clearing continues on request and with the municipality paying half. Nothing about the main network changes on that date. The thinnest roads on the map get thinner.
