Aurora tonight in Inari

Can you see the aurora borealis from Inari?

At Inari's latitude the aurora is ordinary winter weather, not a rare spectacle: the oval sits close enough that even a quiet night can put something in the sky.

Inari needs only Kp 1 and is the largest municipality in Finland by area — a statement about how empty it is. Lake Inari and the surrounding forest hold almost no artificial light, so the sky here is as dark as anywhere in the country and the aurora frequently reaches far overhead rather than sitting on the horizon.

When to look: the Inari aurora season

Counted properly, Inari gets 190 nights of astronomical darkness a year. They begin around **17 Sep** and end about **25 Mar**, and inside that window the sky is dark enough that the only things standing between you and a display are cloud and geomagnetic activity. The counter-season is just as clearly defined: from about **26 Mar** to **16 Sep** (175 nights) the sun never gets 18° below the horizon, so the sky never reaches full darkness, and between roughly 11 Apr and 31 Aug it does not get properly dark at all — no display, however strong, is visible in that stretch.

Two numbers define the year at Inari: roughly 61 days when the sun never sets, and a midwinter night that bottoms out 44.5° below the horizon. Everything worth watching happens in the second half of that pair, and the forecast above will keep saying NO through the first.

Where to go in Inari

Almost anywhere outside the few villages works. Over the frozen lake you get a full, uninterrupted horizon in every direction, which is rare at this latitude.

Face north. Auroral light comes from the oval that rings the magnetic pole, and from Inari that ring lies to the north — so a rooftop, a treeline or a bright shopfront on that side costs you the display no matter how good the forecast is. As for timing, the "best window" figure near the top is the first hour where cloud sits below about 40% during this latitude's darkness.

What Kp do you need in Inari?

Here is what each Kp value would actually put in Inari's sky — the row that matters is the one at Kp 1, which is where this city's magnetic latitude of 68.9° places its threshold:

The most common reason people miss a display at this latitude is timing rather than strength: a Kp 1 night is enough, but substorms come and go inside a single Kp interval, so a 20-minute gap in your attention can be the whole show. Check the sky every 20–30 minutes rather than once.

How tonight's answer is calculated for Inari

Five inputs produce the answer at the top of this page, and every one of them is specific to Inari: the NOAA Kp forecast against a threshold of Kp 1 (35% of the score), cloud cover through the night at 68.91°, 27.02° (25%), the moon (15%), astronomical darkness at this latitude (15%), and light pollution at Bortle 2 (10%).
