Iceland Weather by Month: Winter and Spring on the Troll Peninsula
Iceland weather by month is a story told in seasons rather than in numbers, and for anyone heading north to ski the Tröllaskagi, that is good news: from February to May, each month carries its own light, its own snow and its own character. In short, the Icelandic winter is cold, windy and dark at its heart; then the light returns quickly, and spring brings corn snow, long days and descents that finish at the ocean's edge.
We cover when each of these windows opens in a companion piece: the best time to ski in Iceland. Here we look more closely at the weather in Iceland by month, through the eyes of ski tourers and heli-assisted skiers.
A maritime climate that sets the rhythm
Northern Iceland has an oceanic climate. The island lies in the North Atlantic, at the gateway to the Arctic; the weather turns fast, the wind matters as much as the thermometer, and the sea is always close. The Icelandic Met Office, Veðurstofa Íslands, publishes the country's climate statistics: the reference for the underlying patterns, beyond the day's forecast.
On the Tröllaskagi, the "peninsula of the trolls", the mountains rise straight from the fjords. The north faces hold cold snow late into the season, and it is there that the finest descents are found.
February: the heart of winter, with the light on its way back
In February, Iceland's weather belongs firmly to deep winter: cold, still dark, often windy, with generous snowfalls across the north. The days are already lengthening fast, each week gaining light, and you ski in a wintry mood, on snow that can be light and cold on the north faces.
For the skier, February moves to the rhythm of the weather: you take the fair-weather windows as they open.
March: the balance between winter and spring
March is often the month skiers favour in the north of Iceland. The light is already bright, the days are drawing out, and the snow stays wintry up high and on the north faces while beginning to transform lower down under the sun.
This is the tipping point: cold powder up high in the morning, lovely spring snow lower down in the afternoon. The weather stays changeable, as it always is in Iceland, but the windows grow wider and more frequent. It is one reason March and April open the heli-assisted ski touring season on the Tröllaskagi.
April: spring settles in
April weather in Iceland marks the clear arrival of skiable spring. The days are long, the light generous, and the snowpack begins its cycle of overnight freeze and daytime softening: the making of corn snow. You climb in the morning cold and ski a surface that softens as the hours pass.
The lines that drop towards the fjords come into their own now: leaving a cold summit and finishing on velvet corn at the fjord's edge is one of the Tröllaskagi's signatures. The weather still bears watching, as late-winter storms are possible, but the skiing windows are long and plentiful.
May: the great week of spring
May is the corn-snow month par excellence on the Tröllaskagi, and this is when we take our groups heli-assisted ski touring in Iceland. The days are very long, the light lingers late, and the freeze-thaw cycle delivers, each morning, snow that ripens just right as you climb.
This is the month of our heli-assisted touring week: one helicopter drop a day, then the climb on skins and the silence, for descents of 400 to 800 metres that often end at the fjord's edge. Each day we choose the line according to the snow, the aspect and the avalanche conditions. And if the helicopter stays grounded, because the wind decides here as everywhere, we go ski touring: the Tröllaskagi always has terrain to offer.
In May the nights are already too bright for the northern lights. What we watch for instead is the right hour on each slope, the moment the snow is at its best. That is where the day is won.
In brief: Iceland weather by month, February to May
General climate · oceanic and changeable, with the wind as decisive as the cold
February · deep winter, cold snow, the light returning fast, windows to seize as they come
March · the pivot from winter to spring, bright days, powder up high and spring snow lower down
April · spring settled in, overnight freeze, descents from summit to fjord
May · ripe corn snow, the longest days, the month of our heli-assisted touring week

Join us in May 2027
We are opening a week of heli-assisted ski touring on the Tröllaskagi from 12 to 18 May 2027: seven days, six days of skiing, one helicopter drop a day, small groups of four to five skiers per mountain professional, two groups at most. Places are still available. The full trip is on our page heli-assisted ski touring in Iceland. To see how a week in the north of Iceland unfolds, read our account, the helicopter opens the door, the skins do the rest, and discover the terrain in full in our Tröllaskagi feature.
Your questions on Iceland's weather and snow
What is the best month to ski in Iceland?
March, April and May form the prime window on the Tröllaskagi. March keeps a wintry character with fine days; April settles into spring; May offers the most reliable corn snow and the longest days. Our heli-assisted touring week falls in May. To find the month that suits you, read the best time to ski in Iceland.
Is it very cold for skiing in the north of Iceland?
Winter is cold and windy, especially in February, but the maritime climate softens the extremes you might expect at this latitude. In spring the cold gathers in the mornings, the overnight freeze that readies the snow, and the afternoons turn mild in the sun. The wind remains the real factor to follow.
Will we see the northern lights during the May week?
No. By May the nights are already too bright in the north of Iceland to watch the aurora. That is the trade-off for the long days of light, which are precisely what makes spring skiing so pleasant.
Can we count on the helicopter every day?
Flying depends on the day's weather, and on some days the helicopter stays on the ground. We then go ski touring, with plenty of slopes around the fjords. For conditions and safety across Iceland, SafeTravel Iceland publishes its alerts and advice.
Iceland's weather reads like a calendar of seasons, and the Tröllaskagi's spring is worth the journey: the whole May week is on our Iceland ski touring trip page. Tell us when you would like to come and how many of you there will be, and we will reply within 24 hours.
