Spot: Svalbard Airport Scores updated (Norway time).
Spot: Svalbard Airport Each number is the chance of seeing aurora at least once that night at this spot. It weighs the expected aurora activity, cloud, darkness, moonlight and light pollution.
Other regions:
| Dark enough for aurora | about 23 September to 19 March |
|---|---|
| Polar night | about 27 October to 15 February |
| Clear evenings | About 1 evening in 4 is mostly clear. Of all 5-night stays, about 2 in 3 had at least one (by month). |
| Kp index | a poor guide here, north of the auroral oval at night |
| Outside Longyearbyen | only on a guided tour, because of the polar bear rules |
The nights are dark enough for aurora from about 23 September to 19 March. They are fully dark, with the sun at least 18° below the horizon, from about 9 October to 4 March.
The midnight sun lasts from about 19 April to 23 August.
Both the weather stations and satellite records show that Svalbard is cloudier in October than in February and March.
| Month | Dark hours per day | Fully dark hours per day | Mostly clear |
|---|---|---|---|
| October | 9.8 h | 4.7 h | 19% |
| November | 16 h | 12 h | 21% |
| December | 21 h | 15 h | 25% |
| January | 18 h | 13 h | 32% |
| February | 12 h | 8 h | 33% |
| March | 3.6 h | 0.3 h | 33% |
The table leaves out months with under an hour of darkness a day. Dark hours are the hours a day when the sun is at least 12° below the horizon, dark enough for aurora. In fully dark hours the sun is at least 18° below the horizon. Both are averages over every day of the month, worked out for Longyearbyen. Dates shift by about a day from year to year. You can download these figures as open data from our data sources page.
Mostly clear is the share of night-time observations (19:00–04:00) with cloud covering a quarter of the sky or less, in MET Norway's records for Longyearbyen, 2001–2020. Based on data from MET Norway.
How often a stay had at least one mostly clear evening, by the month it starts.
| Month | 3 nights | 5 nights | 7 nights |
|---|---|---|---|
| October | 40% | 60% | 70% |
| November | 40% | 50% | 60% |
| December | 50% | 65% | 80% |
| January | 55% | 70% | 80% |
| February | 60% | 75% | 85% |
| March | 55% | 75% | 85% |
An evening counts as mostly clear when cloud covers a quarter of the sky or less at the 19:00 observation (20:00 in summer time), in MET Norway's records for Longyearbyen, 2001–2020. Cloudy weather often lasts for days, so we checked each stay night by night. The figures are rounded to the nearest 5%. They describe cloud only and say nothing about aurora. Based on data from MET Norway.
Only Longyearbyen can be reached without a car or a tour.
On Svalbard, the note under each spot says when you can go there only on a guided tour.
| Spot | From town | Sky | Without a car |
|---|---|---|---|
| Longyearbyen | in town | town light | on foot, in town |
| Svalbard Airport | 5 km, 10 min | town light | taxi from Longyearbyen (the airport bus meets flights only) |
| Stay by the terminal and car park. Polar bear rules apply outside town. | |||
| Adventdalen | 10 km, guided tour | very dark | only on a guided tour |
| Warning: Only go on a guided tour. Polar bear rules apply outside Longyearbyen. | |||
| Camp Barentz | 15 km, guided tour | very dark | only on a guided tour |
| Warning: Only go on a booked tour, by bus from town. Polar bear rules apply here. | |||

Do you live near one of our spots? If it causes trouble for you or on the road, write to us at hello@aurorachaser.app and we will remove it.
Each spot gets a score from 0 to 100 for every hour. 60 or more is worth going out. Until it is dark enough for aurora, the page shows tonight's best hour, marked “Forecast”. “Our pick” is the spot with the highest score, or one that is quicker to reach from Longyearbyen when its score is within 5 points. When the highest score is below 25, that margin is a fifth of it. Within that margin, a town's dark spots you drive to come before its centre and airport.

In MET Norway's records, January to March had the clearest skies. See the monthly table.
Any time it is dark enough for aurora, and in the polar night even around midday. In the evening and at night the aurora is usually to the south, and around midday overhead or to the north.
Plan 5 nights or more. In MET Norway's records, most 5-night stays that started between October and March (except November) had at least one mostly clear evening. Aurora must also be active, so no number of nights makes a sighting certain. See the table of stays.
Svalbard lies at about 75.3° geomagnetic latitude, north of the auroral oval at night, so Kp is a poor guide here. Darkness and clear sky matter most.
Yes. The sun's 11-year cycle peaked in 2024–2025, and the Met Office says the years after a peak can often bring strong geomagnetic storms too. At these latitudes the aurora does not need a storm, so the solar cycle matters less here than further south.
Yes, on stronger nights, though street lights hide fainter displays. Our spots in or near town are Longyearbyen and Svalbard Airport. For darker skies, guided tours go to Adventdalen and Camp Barentz.
Outside Longyearbyen you must carry something to scare off polar bears, and a rifle is recommended. To see aurora away from the town lights, go on a guided tour. See the spot table.
Yes, when the sky is clear. The sun stays below the horizon from about 27 October to 15 February, and in Longyearbyen it is dark around the clock from about 13 November to 29 January. Polar night dates for 23 towns.
A bright moon hides faint aurora but barely dims a strong display.
Tonight's forecast is hour by hour. For each of the next 14 nights, AuroraChaser gives your chance of seeing aurora at least once if you look during the dark hours. Any outlook further ahead is only a rough guide to aurora activity.

AuroraChaser's aurora score is a number from 0 to 100 for one viewing spot and one hour. It combines how likely you are to see the northern lights with your own eyes and how bright they should be, so it is not a percentage.
A faint aurora that you are sure to see scores about 60. A phone camera picks up fainter aurora than your eyes can see, so a photo can show aurora while the score is low.
You will very likely see aurora, and the display should be bright. Go out once it is dark enough for aurora.
60–79GoodYou will likely see aurora with your own eyes, though it may be faint. It is worth going out.
40–59ModerateYou have about an even chance or better, and the aurora is usually faint or between clouds.
20–39PoorThere is some chance, mostly of a faint glow.
0–19Very poorThere is little chance, because the aurora is quiet or the sky is cloudy or too light.
Until the sky is dark enough for aurora (the sun 12° below the horizon), the score shows tonight's best hour, marked “Forecast”, unless the live score is already higher. After that, it shows the live score.
“Estimated” means the live aurora data or the weather forecast is missing, so part of the score rests on averages. Alerts pause until the data is back.
The score cannot see a gap in the cloud right above you, fog in your valley or lights close by, such as a headlamp or a lit house. It also does not know your eyesight or how long your eyes have had to adjust to the dark.
