Could El Niño Bring Iceland Clearer Northern Lights Skies This Winter?
Could a weather pattern born thousands of kilometres away in the tropical Pacific give Iceland more clear nights—and therefore more chances to see the Northern Lights—in winter 2026–27?
Possibly. Icelandic meteorologist Einar Sveinbjörnsson has examined the latest seasonal models and believes this winter could bring Iceland fewer of its usual low-pressure systems, more northerly winds and periods of colder, drier, clearer weather. The signal becomes more interesting from November and appears strongest around December and January.
That does not mean every night will be clear, or that El Niño creates stronger auroras. But if the forecast pattern develops, it could improve the one ingredient every aurora hunter needs: a gap in the clouds.
The short answer
Yes, El Niño could indirectly create more Northern Lights viewing opportunities in Iceland during winter 2026–27 by changing the large-scale circulation over the North Atlantic. The current models suggest a possible shift toward higher pressure near Greenland, a storm track farther south and fewer conventional southwesterly lows passing Iceland.
But this is a seasonal probability—not a promise, and certainly not a nightly forecast.
What is happening with El Niño in 2026?
El Niño begins in the tropical Pacific when ocean and atmospheric conditions shift away from their usual pattern. Although the phenomenon starts far from Iceland, it can influence large-scale winds and pressure patterns around the world through atmospheric connections known as teleconnections.
The World Meteorological Organization reported on 3 September 2026 that El Niño was firmly established and likely to become very strong. Its forecasting centres gave an exceptionally high likelihood that it would continue through February 2027.
A strong El Niño does not dictate Icelandic weather like a switch. The North Atlantic has plenty of other moving parts. It does, however, give seasonal forecasting models a powerful climate signal to work with.
Why one Icelandic meteorologist sees a clearer-weather possibility
On 16 September, meteorologist Einar Sveinbjörnsson reviewed the long-range models on Blika. His interpretation was unusually interesting for Iceland.
The October forecasts remained scattered, but the models showed more agreement for November and the strongest agreement around December and January. Across nine forecasting centres, the broad winter pattern was surprisingly consistent.
The projected setup included:
Higher-than-normal pressure near Greenland and eastern Greenland
Fewer of the familiar southwesterly low-pressure systems near Iceland
A North Atlantic storm track displaced farther south toward western Europe
More frequent northerly winds over Iceland
Potentially colder and drier conditions, particularly in southern and western Iceland
In a DV interview published 18 September, Einar described the possible Icelandic outcome as a winter with fewer lows and more settled periods. In plain aurora-hunting language: more cold, starry nights may be possible if the modelled pattern verifies.
Why fewer low-pressure systems could mean more aurora sightings
Clouds are the gatekeeper of Northern Lights viewing. Aurora activity can be excellent above Iceland, but a solid layer of cloud makes it invisible from the ground.
Low-pressure systems crossing Iceland commonly bring cloud, precipitation and strong winds. If fewer of those systems arrive from the southwest—and high pressure becomes more persistent—there may be more nights with clear or partly clear sky, especially in the south and west.
That would not increase the number of auroral events in space. El Niño does not control the solar wind, the interplanetary magnetic field or geomagnetic substorms. It could simply allow people on the ground to see more of the aurora that is already happening above the clouds.
Could Iceland have one of its best aurora-weather winters?
It is possible, but it is too early to crown Iceland the clear-sky champion of winter 2026–27.
The current signal is encouraging because several seasonal models point in a similar direction. However, Einar also stresses that he is interpreting available long-range forecasts, not issuing a guaranteed winter forecast of his own. The precipitation anomaly over most of southern and western Iceland was not statistically significant in the model interpretation.
The Copernicus Climate Change Service and ECMWF also caution that European and North Atlantic winters vary considerably from one El Niño event to another. Polar conditions, the stratosphere and other circulation patterns can strengthen, weaken or overturn the expected response.
So the honest headline is not “El Niño guarantees clear skies.” It is: “A strong El Niño and unusually aligned seasonal models may favour more settled aurora weather in Iceland.”
What this means if you are planning an Iceland trip
If the Northern Lights are a priority, the possible seasonal signal makes November 2026 through January 2027 especially interesting. It should not be the only reason you choose your dates, though.
The practical strategy remains:
Stay for several nights rather than betting everything on one evening.
Book your Northern Lights tour early in your stay so you retain another chance.
If your dates are flexible, choose nights near the new moon for darker skies and better contrast—particularly for faint aurora.
Treat seasonal forecasts as background context, not as a replacement for short-range cloud forecasts.
Check conditions again close to departure, because Icelandic weather can change rapidly.
A full moon does not stop the Northern Lights; it only reduces their apparent contrast. Cloud cover remains vastly more important than moon phase. See NOAA’s aurora-viewing guidance for the distinction.
How to follow the forecast
For the seasonal picture, we will watch whether the model agreement survives the next forecast updates. For an individual tour night, the useful information is much shorter-range: cloud movement, wind, precipitation, road conditions and current space weather.

The verdict
The possibility is real enough to be exciting: a very strong El Niño, a storm track displaced south and higher pressure near Greenland could give Iceland more cold, clear nights during part of winter 2026–27.
More clear nights would mean more opportunities to see the Northern Lights. But the forecast is still probabilistic, and nature retains veto power. For now, we watch the models—and hope the cold arrives with stars.
