What is winter, anyway? What constitutes “winter” is really a matter of definition. Is it winter if it’s snowing? In Iceland, it sometimes won’t snow in the winter. Is it winter if it’s cold? But in Iceland winter doesn’t really get THAT cold.
So, in Iceland, it’s officially “winter” from a specific day in October, officially called “The first day of winter”. In this article, we’ll cover the months roughly from “autumn” until “spring”.
Winter in Iceland is surprisingly mild. In the south, the average temperature is about -2 to 0 degrees Celsius (28-32 F). It can be windy, particularly in January and February when we get occasional storms, though hurricanes are almost unheard of.
But what is the weather like month by month? How should you dress and what should you do with your time here? Read all about it here:
Iceland winter activities:
Most Iceland tours and activities are available year round. The Golden Circle is only snowed out about once every few years, the Blue Lagoon has closed due to weather only once or twice in my three years in the industry, and whale watching is still available in the afternoon, even though the mornings are too dark in the winter.
Some tours and activities, however, are only available in winter:
The Northern Lights: You can only see the northern lights in the winter. The northern lights tours run from late august or early September, until mid-April. Read more about the northern lights.
Ice caves: The Ice caves of Vatnajökull are only approachable in wintertime since they are unsafe in summertime. But the longest man-made ice tunnel in the world is available any time of year.
Dogsledding: Dogsledding is available year-round, but different in the summer and winter. In the winter, you ride on snow in mountainous areas, or even up on a glacier. Contact us for more information about this.

What to wear during Winter in Iceland:
In the wintertime, you should pack winter clothes, hats, gloves and scarves, thick coats and sturdy footwear, maybe even snow trousers.
You will want to bring a warm under-layer such as thick tights, long-johns or leggings. On top of that you will want a warm middle layer and finally a wind-proof layer such as a jacket or snow suit.
