December Driving in Iceland: Essential Guide

Weather in Iceland in December

December in Iceland is cold, stark, and — if you’re prepared — genuinely beautiful. Temperatures typically sit between 28°F and 39°F (-2°C to 4°C), hovering around freezing for much of the month. Reykjavik and the south and west tend to run slightly milder but wetter, while the north and east are often colder and more reliably snow-covered.

Iceland’s winter weather doesn’t follow a neat script. You might get snow, rain, sleet, and a brief spell of sunshine all before lunch. Wind is a constant companion, and it makes the cold feel sharper than the thermometer suggests — especially out in the open. Layering is the only sensible approach: thermal base layers, a decent fleece or sweater, and a waterproof outer shell. Pack a hat, gloves, and sturdy winter boots without overthinking it.

On clear days, the country earns every bit of its reputation. Frozen waterfalls, lava fields dusted in snow, and those low pastel skies that hang around sunrise and sunset for most of the afternoon — it’s the kind of scenery that makes the extra packing worthwhile.

Daylight in Iceland in December

Daylight is scarce in December. Around the winter solstice, the sun rises at approximately 11:00 AM and sets around 3:30 PM — four to five hours of actual daylight, give or take. There’s a slight difference between Reykjavik in the south and Akureyri in the north.

Short as those hours are, they come with a silver lining: the sun stays low all day, so the light is almost permanently golden. It’s genuinely excellent for photography. Plan your driving and sightseeing around those midday hours and you’ll get the most out of them.

Road Conditions in Iceland in December

Winter driving in Iceland is real winter driving — icy surfaces, blowing snow, and weather that can shift from passable to difficult within the hour. The good news is that the main routes, including the Ring Road (Route 1), stay open and are regularly ploughed, keeping connections between Reykjavik, the Golden Circle, the South Coast, and Akureyri reasonably reliable. Stick to these roads for any self-drive trip and you’re in the best position.

That said, expect compacted snow, slippery junctions, and black ice — especially in shaded valleys, along the coast, and further north. Visibility drops fast in a snowstorm or fog, and crosswinds on open stretches, bridges, and mountain passes can catch you off guard. Keep your speed down, headlights on, and don’t pull over on the roadside unless there’s a genuine emergency.

Secondary and gravel roads are a different matter. They often become impassable after storms or freeze-thaw cycles. The Westfjords and Eastfjords see regular temporary closures due to snowdrifts or avalanche risk, and all Highland F-roads close from late autumn and don’t reopen until summer.

Most of the south and west are manageable, but checking conditions before you set off each day is non-negotiable.

How to Check Road and Weather Conditions

Conditions can change fast. Before any drive, check these official sources — and check them again in the morning if you checked the night before.

• Weather Forecast: Visit vedur.is for forecasts from the Icelandic Meteorological Office. It covers wind, temperatures, storm alerts, and visibility in real time — the same resource locals use before heading outdoors.

• Road Conditions: umferdin.is, run by the Icelandic Road and Coastal Administration, has live road maps and webcam feeds showing whether routes are icy, snow-covered, or closed. Wind warnings and regional travel difficulty ratings are also listed there.

• Travel Alerts: safetravel.is, operated by ICE-SAR (Icelandic Search and Rescue), publishes up-to-date alerts and safety advice for roads and the outdoors. You can also register your travel plan through the site or app so rescue teams know to look for you if you don’t check in.

• Emergency Assistance: The 112 Iceland App links directly to Iceland’s emergency services and sends your exact GPS location when you trigger a distress signal. Download it before you leave — it’s essential if you’re heading anywhere remote.

5 Essential Tips for Safer Driving in Iceland in Winter

Winter driving here rewards patience and a light touch. A few things worth keeping in mind:

• Adjust Your Speed to Conditions: Roads can look clear and still be glazed with ice underneath. Ease off the accelerator when temperatures drop below freezing or visibility closes in.

• Use Gentle Control: Hard braking and sharp steering are the quickest routes to losing grip on packed snow or ice. Smooth, deliberate inputs keep the car where you want it.

• Watch for Wind Exposure: Crosswinds hit hardest on bridges, open plains, and coastal roads. Keep both hands on the wheel and be careful opening car doors in a gust.

• Maintain Safe Distances: Leave more space than you think you need between your vehicle and the one ahead, particularly on gravel or icy surfaces.

• Stay Flexible: Road closures and sudden storms happen. Locals know when to sit tight and wait it out — there’s no shame in doing the same.

Driving Regulations and Local Practices in Iceland

A few rules worth knowing before you get behind the wheel:

• Seat Belts: Mandatory for all passengers, no exceptions.

• Speed Limits: 19–25 mph (30–40 km/h) in urban areas, 50 mph (80 km/h) on gravel roads, and 56 mph (90 km/h) on paved rural highways.

• Off-Road Driving: Strictly prohibited. Iceland’s landscapes are fragile and the fines are steep.

• Fuel and Navigation: Fuel stations thin out quickly outside the main towns. Fill up whenever you can, and carry offline and printed maps as backup — mobile signal isn’t guaranteed everywhere.

If the prospect of solo winter driving feels like too much, guided tours and self-drive packages with 24/7 local support are worth considering. With the right preparation, though, a December road trip is one of the more rewarding ways to see Iceland.

Renting a Car in Iceland in December

Hiring a car is the best way to see Iceland on your own schedule. A December drive lets you reach snow-filled valleys, frozen waterfalls, and black sand beaches where the Atlantic crashes in with real force — places that are hard to fully appreciate from a tour bus window. Having your own vehicle means you stop when you want and leave when you’re ready.

Best Rental Car for a Road Trip in Iceland

For a December road trip, a 4×4 SUV is the right call. The extra grip, stability, and ground clearance matter on icy roads. All rental vehicles come with winter tires, but studded tires give you an added margin of confidence on snow and slush.

If you’re staying in Reykjavik or doing something short like the Golden Circle, a smaller car will get you there — just factor in slower progress when conditions deteriorate. For anything along the South Coast or the full Ring Road, a 4×4 is the sensible choice.

Plan your itinerary carefully and use Iceland’s largest rental car marketplace to compare options and find the right vehicle for what you’re planning.

Best Rental Car for Reykjavik in December

For Reykjavik itself, a small or compact car with winter tires is perfectly adequate. City roads are well maintained and cleared quickly after snow, and a smaller car is much easier to park around town.

If you’re planning day trips out of the city — to the Golden Circle or the Reykjanes Peninsula, for instance — a 4×4 rental gives you better traction and more confidence if conditions turn. It’s worth weighing that against the cost depending on your plans.

Whatever you choose, confirm the car has proper winter or studded tires before you sign anything. Most people pick up their rental at Keflavik International Airport before driving into Reykjavik, where parking is easy enough if you use the Parka app. Get the right car sorted and December in Reykjavik is very manageable.

What To See on Your Road Trip in Iceland in December

The Ring Road in December has a lot to offer. Here are some highlights worth building your itinerary around:

• Northern Lights: The long, dark nights of December give you the best conditions of the year for aurora hunting. Get away from city light and give yourself several nights — the more attempts, the better your odds.

• Frozen Waterfalls: Iceland’s falls take on a completely different character in winter. Gullfoss and Seljalandsfoss are both worth a stop — the ice formations around them in December are something else entirely.

• Ice Caves: December is prime season for visiting Iceland’s glacier ice caves. The cold stabilises them and the blue ice is at its most vivid — an experience that’s genuinely hard to describe until you’re standing inside one.

• Icelandic Horses in Winter: Icelandic horses grow thick winter coats that make them look twice the size they are in summer. If you’re heading north, a winter horseback riding tour is worth adding to your plans.

• Black Sand Beaches: Reynisfjara, near Vik, is striking at any time of year, but the combination of black sand, basalt columns, and heavy winter surf against a pale December sky is particularly dramatic. Keep well back from the waves.

• Reindeer in East Iceland: If your route takes you to East Iceland, keep an eye out for wild reindeer. A guided safari is an easy way to find them as they move through the snow-covered mountains and plains.

• Geothermal Hot Springs: After a day of driving in the cold, soaking in a geothermal pool is hard to beat. The Blue Lagoon is the obvious choice, but the Sky Lagoon and Earth Lagoon are both excellent alternatives with a more relaxed atmosphere.

There’s no shortage of things to see on a December road trip around Iceland. Each of these stops offers something different, and together they add up to a trip that’s difficult to forget.
