Daylight, weather and roads
Winter days are short, which limits what you can see. Highland areas are usually snow-covered from September to May or longer, and highland roads are closed. In the lowlands, snow often melts within days or weeks, which can leave icy surfaces; the North and the Westfjords get heavy snow. Visit Iceland advises allowing extra time, expecting weather closures and checking road conditions, forecasts and SafeTravel alerts before you drive; a 4x4 helps in snow. If you do not want to drive, join a tour: the choice is explained in how to get around Iceland. For the next month, see Iceland in February.
What to do
Chase the aurora. The season runs from September to April. The lights are said to be most active around the September and March equinoxes, and mid-winter gives a longer dark window each day. The Icelandic Met Office (en.vedur.is) and Auroraforecast.is give forecasts. A tour is not required, and some countryside hotels offer wake-up calls. See northern lights tours.
Go into an ice cave. November usually marks the start of the natural ice cave season, as summer meltwater subsides. Go only with a qualified guide. For a combined glacier walk, the Skaftafell blue ice glacier hike with a winter ice cave option is rated 4.7 out of 5 from 607 reviews, from €99 on 6 November 2026. The listing offers the ice cave as an option on top of the glacier walk; the park itself is covered in Skaftafell and the full choice in ice cave tours.
Soak. Blue Lagoon winter hours are 08:00 to 22:00 from August 21 to December 31 and 08:00 to 20:00 from January 1 to May 31, with a Comfort ticket from EUR 95 and pre-booking essential. Sky Lagoon is open 10:00 to 21:00 from October 21 to April 30.
Watch the sea. Gentle Giants' GG1 whale tour runs until November 30. Jökulsárlón boat tours wind down as winter approaches, with some amphibian tours possibly running into early November, while the ice cave tour there runs October to April.
Christmas and New Year
There are 13 Yule Lads. Most Icelanders celebrate on 24 December, grocery stores close at noon on 24 and 31 December and are closed on 25 December and 1 January, and some restaurants are closed or limited from 24 to 26 December and on 31 December to 2 January, so book ahead. Sky Lagoon is open 9:00 to 18:00 on 24 December. The Reykjavík firework show at midnight on New Year's Eve is best seen from Hallgrímskirkja or a nearby hill. Akureyri has a Christmas market on Ráðhústorg in late November and December.
Mistakes to avoid
- Driving the highlands in winter: those roads are closed.
- Planning a long day trip with five hours of daylight: choose one region.
- Booking a single night for the lights: Visit Iceland advises several nights.
- Forgetting the road forecast: check SafeTravel and road conditions daily.
