Iceland in December
December is Iceland at its darkest and, paradoxically, most festive.
December is Iceland at its darkest and, paradoxically, most festive. With only 4 hours of daylight, the country runs on candlelight, geothermal heat, and the 13 Yule Lads who visit one by one in the 13 nights before Christmas. Northern lights blaze across skies that are dark for 20 hours a day. Ice caves glow blue. And Reykjavík's Christmas atmosphere is genuine and warm.

December in Iceland is an exercise in extremes. You get 4 hours of sunlight and 20 hours of darkness — which sounds grim until you experience how Icelanders respond to it. Reykjavík is ablaze with Christmas lights. Every window has a candle or a star. The 13 Yule Lads — mischievous trolls from Icelandic folklore — arrive one per night starting December 12th, leaving gifts (or rotten potatoes) in children's shoes.
The northern lights in December are the best of the year, purely because you have so many hours of darkness to catch them. Step outside any clear evening — in Reykjavík, on the South Coast, at your guesthouse in the countryside — and look up. The aurora can appear at 6pm or 2am or both.
Ice caves are at their peak alongside January. The glacial caves in Vatnajökull have had months to stabilise and the ice formations are extraordinary — deep blue, crystal clear, shaped by millennia of pressure. Guided tours run daily from Jökulsárlón and are the standout December experience.
The biggest practical challenge is the darkness. Four hours of light means you cannot see everything in a day. Choose one destination, drive there in twilight, experience it in the brief light, and drive back. Or embrace the darkness — some of the best Iceland experiences (northern lights, hot springs, Christmas atmosphere) happen in the dark anyway.
Frequently Asked Questions
It depends on what you want. If you need daylight to explore, December's 4 hours are limiting. But if you want northern lights, ice caves, Christmas atmosphere, and a unique winter experience, the darkness IS the attraction. Many visitors find December's atmosphere more memorable than summer.
Icelandic Christmas centres on December 24th, when families gather for a traditional meal of smoked lamb (hangikjöt) or roast. The 13 Yule Lads — troll-like figures from folklore — visit one per night from December 12th to 24th. Reykjavík's Christmas markets, concerts, and lights create a genuinely festive atmosphere.
