March is the last month of real winter in Iceland — and the first that gives you daylight to use it. The snow still holds in the north, the glacier ice caves run their final weeks, and the equinox around 20 March statistically boosts aurora activity. Daylight grows from ten hours to thirteen and a half. This guide covers what works in March, what has closed, and what has not arrived yet.
March is winter with daylight. The snow holds, the glacier caves are open for a few more weeks, and the nights are still dark enough for aurora. What changes is the margin. The month gains close to three and a half hours of light, and that margin quietly fixes most of what makes deep winter hard.
March in Iceland is not spring. In Reykjavík and along the south coast, days sit between −1 and +4 °C. The freeze-thaw line runs straight through the afternoon: rain at sea level, sleet on the pass, snow on the far side. Wind matters more than temperature. A calm day at −2 °C is comfortable. A 20 m/s day at +3 °C is not.
The north is a different month. Akureyri, the Tröllaskagi peninsula and the East Fjords keep full snow cover through March. If you want winter landscapes that still look like January, drive north. This is the last month they are close to guaranteed.
Storms still pass through, usually gone within a day. Plan a buffer, not a fixed schedule.
| 1 March | 31 March | |
|---|---|---|
| Daylight | ≈ 10 h 10 min | ≈ 13 h 30 min |
| Sunrise (Reykjavík) | ≈ 08:35 | ≈ 06:45 |
| Sunset (Reykjavík) | ≈ 18:45 | ≈ 20:15 |
| Typical temperatures | −2 to +3 °C | −1 to +5 °C |
This is the number that changes the trip. On 1 March the sun rises around 08:35 and sets around 18:45 — just over ten hours of light. On 31 March it rises around 06:45 and sets after 20:00 — roughly thirteen and a half. Iceland gains six to seven minutes of daylight every single day in March.
The equinox lands on 20 March. From that date, days are longer than nights for the first time since September. In practice it means you can drive a full leg of the Ring Road, stop at three waterfalls, and still reach the guesthouse in daylight. In January that sentence was fiction.
Nights stay dark enough for aurora all month. Even on 31 March, Iceland still gets several hours of usable darkness after full dusk. And March carries a real statistical edge.
The equinox effect. Geomagnetic activity is measurably higher in the weeks around the equinoxes than around the solstices. The accepted explanation is the Russell–McPherron effect: near the equinoxes, the geometry between Earth's magnetic field and the solar wind lets southward-pointing solar magnetic fields connect with ours more efficiently, so more charged particles get in. The result is more frequent geomagnetically active nights in March and September. It is a tilt in the odds, not a switch — cloud cover still decides whether you see anything.
The routine does not change: dark sky, clear sky, patience. Check the northern lights forecast each evening, drive away from town lights, and give it more than one night. Three or more nights in-country puts the probability firmly on your side.
The natural blue-ice caves under Vatnajökull run from roughly November to the end of March. Most close in the last week of the month, when melt begins and water starts moving under the glacier. Guides scout the ice daily near season's end and make the call; some years the season stretches into early April, some years it ends mid-March. Treat the end of March as the deadline, not a promise.
Two consequences follow. First, March is the last chance until next winter — nothing reopens in April. Second, final-season departures sell out, because everyone with a spring trip has the same idea. Book the cave tour before you book anything else. The full picture — which caves, which operators, how the season is decided — is in our ice cave season guide.
One honest exception: the ice cave under Katla, reached from Vík, runs most of the year. The ice is older and streaked with ash — a different sight, not a lesser one — and it does not disappear in April.
In December and January, driving the whole Ring Road is a gamble against ten-hour storm closures and seven-hour days. In March the odds shift. Daylight stretches past twelve hours, road crews clear faster, and a closed pass usually reopens the same day. For a confident winter driver, the full circuit is realistic again — the extra light is exactly the margin that lets you wait weather out instead of driving through it.
It is still a winter drive. Check today's road conditions every morning, keep daily legs short, and hold one buffer day. Rental cars carry winter tires by law until mid-April; take the 4x4 anyway for the north and east. Our 7-day Ring Road itinerary works in March as the minimum version — nine or ten days sits easier at this time of year.
The highlands stay shut. F-roads do not open until June at the earliest, so Landmannalaugar and Askja are not part of any March plan.
March is shoulder season. Flights and rooms cost clearly less than summer, and less than the Christmas–New Year peak. Tour availability is wide open outside the ice caves.
The one date to watch is Easter, which moves. In 2027 it falls early — Easter Sunday is 28 March — so that year the final week of March carries holiday pricing and Icelandic families on the road. In most years Easter lands in April and all of March stays quiet. Check the calendar for your year before assuming the whole month is cheap.
A note on DesignMarch, since the name misleads: Reykjavík's design festival has drifted later in the calendar, and the 2027 edition runs 7–11 April. If your trip slides into early April, it is worth a day; a pure March trip will miss it.
And the honest list of what is not here yet: puffins return from the open sea in late April, so the cliffs at Dyrhólaey and Látrabjarg are empty of them in March. Highland hikes wait until summer. Whale watching runs from Reykjavík all month, and seals are around all year.
The verdict: March is the connoisseur's winter month. It is the only point in the year when aurora odds, open ice caves and workable daylight overlap. Deep winter has better darkness, summer has better roads — March is the compromise that gives up the least.
Yes, for winter scenery with easier logistics. You get snow-covered landscapes, aurora-dark nights and open ice caves, plus 10–13.5 hours of daylight and shoulder-season prices. What you give up is summer access: no highlands, no puffins, and weather that still demands flexible plans.
Yes — March is the final month. The natural blue-ice caves under Vatnajökull typically operate until the end of March, then close as melt begins. Exact closing dates depend on the ice and shift year to year. Book early; late-season departures sell out. The Katla ice cave near Vík runs most of the year.
Yes, all month. Nights remain dark enough even in the last week, and geomagnetic activity is statistically elevated around the 20 March equinox. You still need clear skies and some patience — plan at least three nights and check the forecast each evening.
Yes, if you are comfortable driving in winter conditions. Longer days give you room to wait out weather, which is what makes the full circuit realistic again. Take at least seven days, ideally nine or ten, check road conditions daily, and keep one buffer day.
No. Puffins spend the winter at sea and return to their nesting cliffs in late April. If puffins are the point of the trip, come between May and mid-August. In March the coastal birdlife is gulls, fulmars and sea ducks.
