Weather in Iceland in December: A Full Guide

What is the average temperature in December in Iceland?

While November is considered the month when winter begins in Iceland, it’s in December when it comes into full effect. It’s, in general, a cold month, but it’s colder by the end than at the beginning. The average temperature in December hovers around 0°C (32°F) but can vary significantly depending on the time of day and location.

In Reykjavik, the capital, temperatures typically range from -1°C to 4°C (30°F to 39°F). Coastal areas tend to be milder due to the influence of the North Atlantic Ocean. However, the wind can make it feel colder than it actually is. In the Central Highlands and the northern regions, the temperatures are normally colder, often below freezing.

Despite these chilly temperatures, Iceland’s winter is relatively mild compared to other regions at the same latitude, thanks to the oceanic influence that moderates the climate.

How much does it rain or snow in December in Iceland?

December in Iceland is usually a wet month, with frequent precipitation in the form of rain, snow, sleet, or a mix of all three. On average, there are 15 rainy or snowy days during the month.

The amount of precipitation can vary depending on where you are in the country. Generally, coastal areas receive more rain and snow than inland regions.

Snowfall is common, especially in the north and the Westfjords, creating a winter wonderland effect on the landscapes that is incredibly beautiful. However, the weather can be unpredictable, with storms and blizzards occurring suddenly, leading to rapidly changing conditions.

Daylight Hours in December

Daylight in Iceland changes a lot throughout the year because it's so far north, close to the Arctic Circle.

Daylight hours in December are scarce. The shortest day of the year is December 21st, the winter solstice. In Reykjavik, daylight lasts for about 4 to 5 hours at the beginning of the month, decreasing to just under 4 hours by the solstice.

In northern regions, the daylight hours are even shorter, and in some areas close to the Arctic Circle, the sun barely rises above the horizon. This phenomenon is known as polar twilight, as the sun is never fully out, and there’s just a dim light that lightens the sky. This allows you to see the country in a completely different light compared to other months, and it’s a beautiful scene.

The extended dark hours come with great news, too. During the night, in winter, is when there are more chances to see the Northern Lights, one of the most amazing and surprising things that can be witnessed in Iceland.

The weather in different regions of Iceland in December

Iceland’s weather can vary significantly from one region to another. The sea and the altitude can have a direct impact on a region’s climate, especially in December.

Reykjavik and the South Coast

This area experiences milder temperatures due to the ocean’s influence. Rain and snow are common events. The most distinctive feature is the wind, which can change the weather at a moment's notice, going from a storm to sunshine in a matter of minutes.

The Westfjords

This remote region is known for its heavy snowfall, and it’s often colder and more prone to winter storms. Travel can be challenging due to snow-covered roads.

North Iceland

This area experiences some of the coldest temperatures in the country, apart from the Highlands. Snow is frequent, and the number of daylight hours is the lowest in December, but it’s also a great place to see the Northern Lights.

East Iceland

Similar to the north, the east is cold, and it snows often. On the other hand, it’s less windy than some other parts of the country.

The Highlands

Winter is a difficult time in the Central Highlands. They are usually inaccessible in December due to heavy snow. This part of the country has many unpaved roads that close under adverse weather.

What to Pack for the Weather in December

Packing for a trip to Iceland in December requires careful consideration to ensure you stay warm and dry in the often-harsh conditions. However, it’s not necessary to pack a huge suitcase full of things. If you are able to combine elements well, you’ll be able to adapt to the weather in Iceland in December.

This system will keep you warm while allowing you to adjust to changing temperatures. If you are going to colder areas, a good coat can come in handy, but make sure it’s waterproof.
• Winter accessories: Pack a warm hat, gloves, and a scarf to protect against the cold and wind. Wool or thermal socks are also essential.
• Waterproof gear: A waterproof jacket and pants are necessary to stay dry during rain or snow. Waterproof and insulated boots are also a must, especially if you plan on exploring Iceland’s natural sites.
• Sunglasses: Even if the sun doesn’t show up much this month, and it’s low in the sky, its reflection on snow or ice can be very harmful to your eyes.
• Backpack: It can be a great ally during your excursions. You can carry snacks, water, a change of clothes, or extra layers to help you adapt to the weather changes.
