Campervan in Iceland in March

Reykjavík goes from 10 h 09 min of sun on 1 March to 13 h 25 min on the 31st, gaining about six and a half minutes a day with no plateau and no clock change to interrupt it. That is the largest total swing of any month in the off-season — larger than February's recovery and larger than the autumn losses that mirror it. In practical terms, a first-week trip has a working day about the length of a late-October one and a last-week trip about the length of a mid-September one. Those are not the same itinerary.

The north changes fastest. Akureyri starts March about nine minutes behind Reykjavík and ends it six minutes ahead, gaining seven minutes of sun a day against the capital’s six and a half. The two swap places on the 18th or the 19th, close to the equinox but not because of it: the equinox is simply the date the sun’s declination reaches zero, while the crossover is a matter of which latitude is gaining faster. If your route is weighted towards Akureyri, Mývatn and the north coast, the second half of March buys you more than it buys a south-coast trip.

Where the light sits in the clock day matters as much as how much of it there is. Iceland stays on GMT all year by statute and sits well west of the natural meridian for that zone, which puts the middle of the daylight window in Reykjavík between about 13:30 and 13:40 all month rather than at noon. The consequence in March is a genuinely late sunset — 20:14 in Reykjavík on the 31st — and a sunrise that is still after 08:30 in the first days of the month. Shift the whole driving day an hour later than instinct suggests and you get the light rather than fighting it. Icelanders notice the mismatch too: a petition to move the country's clocks back an hour, closer to solar time, had passed three thousand signatures by November 2025.

Icelanders do not date spring from the equinox either. The traditional marker is a bird: the first confirmed sighting of the returning golden plover, lóan, is reported in the national press and treated as the real start of spring, and it commonly falls in March. Iceland holds roughly a third of the world population of the species, so the marker carries some weight.

Both Icelandic authorities that have to take a position on this put March in winter, and our own winter guide sets out the institutional case. What matters at the point of booking is what follows from it. Every equipment decision that applies in January still applies in March: heat that runs with the engine off is the difference between a route and a set of powered pitches, bedding is a paid extra at several companies rather than an assumption, and the campsite list you plan around is the winter minority. Nothing about the equinox loosens any of that.

Three things do change, and all of them are commercial rather than meteorological. The rentable fleet widens twice inside the month, which is unusual — most seasonal windows in this market open in April or May, and the dates are worth having before you compare quotes. Demand firms up as the month runs on, so the last week prices differently from the first. And March is the last month before the spring band, which is the real reason a March trip is worth pricing against an April one rather than against a February one.

The date inside March with an official meaning is the 20th, when Vegagerðin’s spring road-service period begins, and it sounds larger than it is. It governs the lowest-priority rural roads, cleared at most twice a week and only while conditions are light on snow. Those roads have had no funded scheduled clearing since 5 January, after which Vegagerðin’s cost cover ends and clearing continues only on request, with the municipality paying half. The spring period puts them back on a schedule and changes nothing about the Ring Road, the passes or the highlands.

On 15 March, Reykjavík's window of true darkness runs from 22:14 to 05:00, six hours forty-six minutes of it; Akureyri gets six hours twenty-four. That is three hours less than the same date in February and it is still more than a full night's sleep. It is also enough that you do not have to choose between the aurora and the driving: the same date gives eleven hours forty of sun. No other month in the season offers that balance, because the months with more darkness have far less day and the months with more day have no darkness at all.

What ends the season is arithmetic, not the sun going quiet. The geomagnetic activity that drives the aurora is, if anything, slightly elevated around the equinoxes — a real effect, measured, and much smaller than the popular claim implies; our month-by-month breakdown sets out the numbers and takes the March half of the September-and-March folklore while rejecting the September half. What collapses is the budget of dark hours you have to spend those odds on. By the end of March a viewing night starts late and ends before it has properly settled, and the operators price that in: Reykjavík's aurora boats move their departure from 21:00 to 22:00 on 15 March and stop sailing on 15 April.

The practical consequence for a camper is that March aurora hunting is a late-evening activity you cannot start early to get out of. In December you can be under a dark sky at 18:30 and in bed by 22:00; in mid-March the earliest useful moment is after 22:00, and the second half of the month pushes it later still. Travelling with children, or with a driver who has a long day behind them, plan for a shorter and later window — and for the fact that a clouded-out March night cannot be salvaged by waiting, because there is less night left to wait in.

Through the depth of winter, McRent's Iceland operation runs on a single motorhome group. The others come back on 8 March and 22 March, with the last waiting until 19 April — dates we derived by probing their own booking engine week by week across a year, because they are published nowhere. That makes March the only month in which the range of vehicles on the Icelandic market measurably widens twice, weeks before any highland road opens and before most seasonal campsites reopen. It is the earliest visible signal that the season is turning, and it is a commercial signal rather than a meteorological one.

Other vendors move the opposite way, which is the part that surprises people. Go Campers rent their two-berth 4x4 California Beach only from 15 September to 14 May, so March is inside its window, while the four-berth version of the same van does not return until 20 April — one vehicle, two opposite seasons. Lava Car Rental’s single camper cannot be booked in March at all: their engine takes no pickup before 30 April, a window published nowhere and derived by probing. CampEasy publish no windows at all, so their whole range is nominally on offer.

None of that changes the specification question, which is the same in March as in January and is covered properly in our heating guide. Ask for the heater type by name and ask whether it works away from a hookup. A camper that only heats on a powered pitch ties every night of a March trip to a site that is both open and has working electricity, and in March that is still a short list. The drivetrain question comes after it, in the order set out further down this page.

Highland roads are not merely closed in March, they are closer to their worst state than to their best. Vegagerðin publishes opening dates for the mountain roads and no closing dates at all, and opening is a physical judgement rather than a calendar entry: joint field inspections with the Environment Agency and Vatnajökull National Park, two conditions that must both hold — the frost out of the road, and no risk of damage to the ground or to infrastructure. Across 2021 to 2025 the earliest single opening of any tracked route was 23 May. From the equinox that is nine weeks. For Sprengisandur and the Eyjafjörður highland links, which typically open late June to mid-July, it is closer to fifteen. Our road-conditions article carries the full opening record.

The reason sits in a statistic that explains March better than any temperature does. Snow cover on ground at 500 to 700 metres near Reykjavík averages 81.6% of mornings in March — the highest figure of any month of the year at that elevation, above January and above February — while the town below drops back to about half. That band is where the mountain passes and the highland roads live. The lowlands greening up tells you nothing at all about the terrain the F-roads cross, and March is precisely the month in which the two diverge most.

There is a piece of dated history that makes the point better than an argument. The Fimmvörðuháls fissure opened at 23:52 on 20 March 2010, the first act of the Eyjafjallajökull eruption, and by coincidence on the exact date of that year's equinox. The routes into Þórsmörk and over the pass were closed the same day. They reopened on 29 March for four-wheel drive only, a second fissure opened on 31 March and forced another closure, and access came back on 1 April. That is what highland access looks like in late March even when a volcano is drawing every super-jeep in the country towards it.

March 2023 was the coldest March in Iceland since 1979, with Reykjavík averaging −1.6°C, 2.8 degrees below the thirty-year norm. The same month, in the same city, delivered 5.0 mm of precipitation — six per cent of normal, the second driest March there since 1962 — and 207.5 hours of sunshine, the second sunniest since records began in 1871. March 2025 went the other way: Reykjavík averaged 3.1°C, 1.9 degrees above normal, with 104.1 mm of rain, 91.6 hours of sun and only three fully snow-covered mornings. Both are official Met Office monthly summaries. Neither is a freak.

The useful lesson from that pair is counter-intuitive and worth carrying into your own forecast reading. In the Icelandic southwest, cold and clear travel together. A northerly flow that starves Reykjavík of warmth starves it of rain at the same time, which is why the coldest March on record was also nearly the sunniest. A cold forecast for the capital is not a wet one, and a mild forecast very often is. Plan the photogenic days around the cold snaps rather than against them.

The normals, for what a thirty-year average is worth in a month this variable: Reykjavík averages 1.2°C in March, with a mean daily maximum of 4.2°C and a mean minimum of −1.3°C, snow lying on about 9.6 mornings, 80.7 mm of precipitation and 110.3 hours of sunshine. Akureyri sits on 0.0°C with snow lying on about 16.1 mornings, roughly half the month, and 47.4 mm of precipitation, a little over half the capital’s. Vík is the mildest at 1.9°C and by far the wettest at 184.7 mm. Ísafjörður is the outlier: on its own long-run series March averages −1.6°C, colder than its own January, and it is the only station in the set where late winter beats midwinter for cold. Those last two come from an older normal period than the capital’s, so read them as shape rather than as current values.

The hazard that genuinely peaks in March is not wind or cold but the accumulated snowpack coming off the slopes above the fjord towns. Three avalanches fell above Neskaupstaður overnight on 26 and 27 March 2023; Civil Protection declared an emergency phase and about 500 residents were evacuated there and in Seyðisfjörður and Eskifjörður. The phase was downgraded on the 28th, a further slide fell on the 29th, and by the 30th evacuation orders had reached three more towns. Nobody was hurt. On 17 March 2024 the Met Office issued a nationwide storm and avalanche warning with an uncertainty-level declaration for the northern Westfjords. If your route runs east or north-west in the back half of March, that is the risk to watch, and it is why roads sometimes close on avalanche grounds when the weather itself looks survivable.

Natural ice caves are the item with a deadline on it, and March is the last full month in which one is a plannable part of a trip rather than a hope. Why they are a winter product at all is set out in the November guide; what March owns is the closing edge of the season. Operators end it on a judgement their guides make standing on the ice rather than on a date, no authority publishes a season for them, and the back end of March is where a departure is most likely to be moved or dropped. If a cave is a reason for the trip, book it early in the month and treat it as the fixed point the rest of the itinerary bends around.

Two things are at their best rather than at their end. Lava tubes hold a near-constant one or two degrees inside all year, but meltwater and snow at the entrances freeze into ice columns and curtains through late winter, so the caving is visually at its most distinctive in exactly these months, on a reduced winter timetable. And the whales are arriving rather than leaving: the capelin spawn along the south coast in early March, which is why humpback sightings out of Faxaflói peak either side of it, and orcas are a cold-season sighting rather than a summer one. The port worth getting right is Húsavík. Reykjavík and Eyjafjörður sail all winter; the town whose whole reputation is whales does not. North Sailing’s own winter statement puts its Húsavík route out of service until 1 March, so the famous harbour comes back on the first day of this month rather than in the spring, while the town’s other main operator is reported to start on 1 April — a secondary figure we could not confirm. Ask which company is sailing before you drive north for it.

Everything else divides between the reliable and the conditional. The tourist lagoons run winter timetables, generally shorter than the summer ones, so check the last-entry time rather than the closing time. Ski areas are the conditional case and should never be treated as a fixture: all three of Iceland’s main ones open and close on snow conditions rather than on dates, and a bad snow year can leave the nearest one to Reykjavík running for a handful of weekends. Puffins are simply absent — the first birds return in April, and no March itinerary should include them.

With eleven to thirteen hours of sun, the daylight stops being the thing that rules routes out. What replaces it is a pair of constraints that do not appear on a map. The first is the campsite list, which is still the short winter one rather than the long summer one. The first seasonal reopening of the year falls in mid-March at Grindavík, according to the municipality’s own calendar — though the town’s post-eruption situation makes that one unreliable whatever any calendar says — and the sites most travellers want are still weeks away. Vík has none trading in March: its operator’s page is reported to reopen the site on 20 April, a date we could not verify and which one third-party overlander log puts as late as 1 June. Either way, Skaftafell is the single serviced waypoint on the whole south-coast stretch, running two of its zones with the outdoor water off until mid-May.

Even the sites that stay open are running a reduced version of themselves, and one detail is specific to March: Þingvellir's year-round site at Nyrðri-Leirar has no showers from 1 December to 1 April, so a March trip through the Golden Circle never sees them. Plan the shower stops around municipal pools instead — they are cheap, they keep full hours, and they are usually the warmest building in the village.

The second constraint is the passes. The Ring Road's own high points are the ones that decide a March schedule: Holtavörðuheiði, Vatnsskarð and Öxnadalsheiði in the north-west and north, Möðrudalsöræfi in the north-east at roughly 600 metres, which is the highest point on Route 1, and Hellisheiði within sight of the capital, which closes as often as anything in the country and takes Þrengsli with it more often than the backup theory allows for. None of these close for the season; they close for a day, sometimes a night, and reopen. That is a planning problem rather than a safety one, provided the schedule has slack in it. Our road-conditions article covers how to read the map, and what to do when the weather rewrites the route has a page of its own.

The Westfjords are the exception where the honest answer is not this month. The gateway passes close independently of one another, and Dynjandisheiði is reported to have among the shortest winter service hours in the country — local coverage of Ísafjarðarbær’s own request for more of it quotes no crew on duty after 5pm on weekdays or at all at weekends, a figure we could not re-verify against the original. The region also has the thinnest documented winter campsite coverage anywhere in Iceland. It is unreliable rather than merely slower from October through April, and April can be worse than midwinter.

The second decision is the vehicle, and in March it is worth doing in the order the conditions impose rather than the order the booking form implies. Heat that works with the engine off comes first, because it decides whether your route is free or tethered to powered pitches. Tyres come second, because they do more for stopping distance than any drivetrain. Cancellation terms come third, because March is the month with the widest weather envelope in the year and the value of being able to change your mind is at its highest. Four-wheel drive comes fourth, and for most March itineraries it does not come at all.

Then price the same dates across companies rather than reading one rate card. Seasonal windows differ enough between vendors that the same March week returns a genuinely different roster from each of them, and the two dates on which the market widens mean a quote taken on the 5th and one taken on the 25th are not surveying the same fleet.
