In short

Northern lights in Abisko do not wait for a storm: the city sits at 66.3° N geomagnetic latitude, inside the auroral oval already at Kp 0, where NOAA's rule of thumb puts the oval's equatorward edge at about 66°. Any Kp is enough with a dark, clear sky, and the cards on this site use Kp 1, the lowest value they show. Fully dark nights in Abisko (sun 18° below the horizon) run from 14 September to 29 March. 3 guided tours leave from Abisko with at least 4.3 stars and 20 reviews, from 120 USD. The aurora probability over the city right now, from NOAA's OVATION model, is on this page and refreshes every 15 minutes.

  • Aurora probability over Abisko from NOAA OVATION, refreshed every 15 minutes with the fetch time shown
  • 3 guided tours pass the filter of 4.3 stars, 20 reviews and an aurora title
  • Kp forecast for the next 3 days in 3-hour slots, and the other places in Sweden for comparison

Aurora probability over Abisko1 %

Kp needed1+ 66.3° N geomagnetic
Max Kp 24 h6.00 G2

Data: NOAA SWPC, fetched 14:10 UTC. Aurora probability by destination from the NOAA OVATION model, forecast for 9 Oct, 15:10 UTC. Aurora also needs a dark and clear sky. Kp needed: NOAA puts the edge of the auroral oval at about 66° geomagnetic latitude for Kp 0, 2° closer to the equator per Kp level. Geomagnetic latitude from the WMM2025 dipole pole (NOAA NCEI).

2The Kp index Abisko needs

Abisko lies at 68.3° N, which is 66.3° N geomagnetic latitude on the WMM2025 dipole. NOAA's viewing tips put the edge of the auroral oval at about 66° geomagnetic for Kp 0 and move it about 2° closer to the equator with each Kp level, down to 48° at Kp 9. At 66.3° N Abisko is inside the oval before any storm begins, so the cards on this site use Kp 1, the lowest value they show. NOAA also notes that aurora can often be observed hundreds of kilometres equatorward of the oval's edge, so a bright display can show low on the northern horizon one Kp level earlier.

4When the sky over Abisko is dark enough

The aurora needs a dark sky as much as it needs Kp, and darkness is a matter of latitude and date. Fully dark nights in Abisko (sun 18° below the horizon) run from 14 September to 29 March. From 15 April to 27 August the sky never gets darker than nautical twilight, so only a strong display shows, low on the horizon. The polar night lasts from 6 December to 5 January, 31 days with the sun below the horizon all day, when the aurora can show in the afternoon. The midnight sun lasts from 24 May to 18 July, 56 days. Dates are an own calculation from the sun's declination for the latitude of Abisko, with the US Naval Observatory definitions of twilight, and can be a day off at the edges. Clouds and moonlight are the other half of the question: the home page shows the moon phase for each of the next 27 days.

5Why Sweden for the northern lights

Swedish Lapland has two bases an hour apart. Abisko is known for a drier, clearer sky than the coast, sheltered by the mountains, and for the Aurora Sky Station on Mount Nuolja. Kiruna has the airport and the ice hotel in nearby Jukkasjärvi. Both sit at the edge of the oval, so Kp 1 is enough on a clear night.

Frequently asked questions

What Kp index do you need to see the northern lights in Abisko?

Any Kp with a dark, clear sky. Abisko sits at 66.3° N geomagnetic latitude, inside the auroral oval already at Kp 0 by NOAA's rule of thumb, which puts the oval's edge at about 66°. The cards on this site use Kp 1, the lowest value they show.

When is the best time to see the northern lights in Abisko?

Fully dark nights in Abisko (sun 18° below the horizon) run from 14 September to 29 March. The darkest skies of the month are the 5 nights around the new moon. The home page shows the moon for each of the next 27 days.

Can you see the northern lights in Abisko in summer?

From 15 April to 27 August the sky never gets darker than nautical twilight, so only a strong display shows, low on the horizon.

How many northern lights tours are there in Abisko?

3 guided tours from Abisko pass the filter of 4.3 stars and 20 reviews, from 120 USD per person, counted from the booking catalogue on 9 Oct 2026.

Is Abisko the best place in Sweden for the northern lights?

By Kp needed both places in Sweden on this site are level at Kp 1, Abisko included. Clouds and light decide the rest.

Why does the Abisko aurora probability on this page change?

It comes from NOAA's OVATION model, a forecast for the next 30 to 90 minutes, which this site re-reads at most every 15 minutes. The Kp needed, 1, does not change: it is geography.
