Iceland in December: what to expect

December is the darkest month in Iceland. Reykjavík gets roughly 4–5 hours of usable daylight around the solstice, and the sun stays low, so most of the day feels like late afternoon. That is not a problem for aurora hunting, but it does mean you plan around light: one main outdoor stop per day, not four.

Temperatures sit near freezing in the southwest, with wind doing more damage than the thermometer suggests. The south coast is the wettest and windiest lowland, and high winds or sandstorms can close Route 1 in places. The north and east around Akureyri and Mývatn are colder and drier, often with more snow and clearer skies. The highlands are closed; F-roads do not reopen until roughly late June.

Snow is normal, but so is rain and sleet at sea level. Roads are usually passable with winter tyres, yet closures happen with little warning. Check road and weather conditions each morning before you commit to a long drive.

Crowds are medium overall but split sharply by date. The first three weeks of December are quiet, with low-season hotel rates in Reykjavík and easy availability on south-coast tours. From around 20 December the country fills with Christmas and New Year visitors, and prices jump to peak-season levels.

Book accommodation and any ice-cave or glacier tour well ahead for 24 December to 2 January. Outside those dates you can often book a week or two out. Expect high prices for car hire, fuel and restaurant meals all month; the holiday period adds a premium on top.

Christmas dominates the month. Shops and restaurants close from mid-afternoon on 24 December and again on 31 December, so plan food and fuel around those days. Reykjavík runs Christmas markets and lights through December, and the city's New Year's Eve fireworks are famously large and mostly private — locals set them off from gardens and streets rather than one official display.

Aurora season is in full swing, and ice-cave tours from the Vatnajökull area run roughly November to March with guides. Whale-watching from Húsavík and Reykjavík continues on a reduced winter schedule, weather permitting. Check individual operators for December dates.

Stay in the southwest. Reykjavík makes a comfortable base for the Golden Circle, the Reykjanes peninsula and aurora tours, and you can reach the south coast as far as Vík on a good day. Beyond Vík, ice and wind make the drive to Höfn and Jökulsárlón a serious winter trip: doable with a guide or good winter driving experience, but not a casual day out.

In the north, Akureyri and the Mývatn area are colder but often clearer, which helps for auroras. Flights or the long drive make it a separate trip rather than a day add-on from Reykjavík. The highlands and most F-roads are closed.

The practical rule for December: pick one region, keep two or three buffer days, and treat any long drive as optional until you have seen the morning road report.

Pack for wet cold, not deep cold. A waterproof shell and trousers over insulating layers beat a single heavy coat, and waterproof boots with grip matter more than warmth alone. Add a hat, gloves, a buff and sunglasses for low sun on snow.

Bring a headlamp or phone light for the dark afternoons, a swimsuit for geothermal pools, and a power bank since cold drains batteries fast. If you are driving, check that your hire car comes with winter tyres and that you know how to read the road and weather sites before you set out.

November is darker and quieter, with lower prices and the same storm risk. January keeps the short days but adds slightly more light at the end of the month and the Þorrablót food season. February is still stormy but noticeably brighter, and March is the first month with a real balance of light and aurora nights.

If your priority is driving the whole island or hiking, come between June and August instead. If your priority is auroras and ice caves with fewer people, late February and March are usually a better bet than December.
