Tonight's Forecast

Moderate

How we calculate the aurora score

Moderate

We combine geomagnetic activity (Kp), aurora oval probability (OVATION), cloud cover, darkness and moonlight, weighted for Kemijärvi (region: auroral_oval).

With current Kp 5.0 (location needs ≥ 2) and 89% cloud cover, aurora may be visible at Kemijärvi from a dark spot, once your eyes have adjusted.

Unlikely 0-19

Score 0–19. Conditions strongly limit aurora visibility.

Low 20-44

Score 20–44. A faint aurora is possible only under perfect conditions.

Moderate 45-64

Score 45–64. Aurora may be visible to alert observers in dark, clear skies.

High 65-84

Score 65–84. A good chance of a visible aurora display.

Very High 85-100

Score 85–100. Excellent odds — plan to be outside tonight.

Moderate chance tonight. Aurora may be visible from a dark spot if the sky stays clear.

Aurora Score 59 /100

Aurora activity may be favorable near Kemijärvi, but cloud cover could make the Northern Lights difficult or impossible to see.

With current Kp 5.0 (location needs ≥ 2) and 89% cloud cover, aurora may be visible at Kemijärvi from a dark spot, once your eyes have adjusted.

Direction to Look

Overhead or north

Min Kp 2 Lat 66.7°

This location is close to the auroral oval, so aurora may appear overhead during stronger activity.

Recommendation

Cloud cover is the main problem tonight. Wait for breaks in the clouds before going out.

Why this forecast?

There is a moderate chance of visible aurora tonight. Some conditions are favorable, but clouds, moonlight or geomagnetic activity may still limit visibility.

✓

Geomagnetic activity 5.0 / 2

Geomagnetic activity (Kp index)

Strong for this location

Kp measures how disturbed Earth's magnetic field is on a 0–9 scale. Higher Kp pushes the aurora oval toward the equator. Kemijärvi needs Kp ≥ 2.

Below threshold

Kp is below the minimum needed at this latitude.

Near threshold

Kp is close to the minimum needed — a faint aurora may appear low on the horizon.

Enough for this location

Kp meets the threshold for visible aurora here.

Strong for this location

Kp is comfortably above the local threshold.

Geomagnetic storm

Storm-level Kp ≥ 5 — aurora can be seen far south of its usual zone.

Strong for this location

Expected Kp 5.0 is comfortably above the 2 Kemijärvi usually needs, so the oval should reach well past this latitude if the sky cooperates.

Cloud cover 91%

Cloud cover

Overcast

Average cloud cover during the best viewing window. Clear skies are essential — even thin overcast hides the aurora.

Clear skies

Up to 25% cloud — excellent visibility.

Partly cloudy

25–50% cloud — aurora may peek through gaps.

Cloudy

50–85% cloud — most of the sky is blocked.

Overcast

Over 85% cloud — aurora effectively hidden.

Overcast

Cloud cover is high tonight, which can block the view even if aurora activity is present.

✓

Darkness astronomical

Sky darkness

Astronomical darkness

Aurora is faint and needs a dark sky. Astronomical darkness (sun more than 18° below horizon) is ideal.

No dark window

Sun stays above 6° below horizon all night — no aurora-friendly darkness.

Civil twilight

Sun 6–12° below horizon — too bright for faint aurora.

Nautical twilight

Sun 12–18° below horizon — sky is dark but not fully astronomical.

Astronomical darkness

Sun more than 18° below the horizon — fully dark sky.

Astronomical darkness

The sky reaches full astronomical darkness tonight — the sun more than 18° below the horizon, dark enough for even a faint aurora.

Moonlight 77%

Moon illumination

Bright moon

A bright moon washes out faint aurora colours. New moon is ideal; full moon hides everything but the strongest displays.

Dark moon

Less than 25% illuminated — minimal interference.

Moderate moonlight

25–75% illuminated — faint aurora may be washed out.

Bright moon

Over 75% illuminated — only strong displays will be visible.

Bright moon

Moon is 77% illuminated — expect washed-out faint aurora.

•

Aurora oval probability 10%

Aurora oval probability (OVATION)

Moderate

NOAA's OVATION model estimates the chance of aurora visible overhead within a 250 km radius of you.

Low

Less than 5% probability — aurora unlikely to reach this location.

Moderate

5–20% probability — aurora possible.

Elevated

20–40% probability — aurora likely if skies are clear.

High

Over 40% probability — aurora very likely overhead.

Moderate

The aurora oval probability is moderate for this location tonight, so activity may be close by if the sky is clear.

✓

Aurora zone Excellent zone

Aurora zone

Excellent zone

How favourable Kemijärvi's latitude is for aurora viewing in general — independent of tonight's conditions.

Low zone

Lower latitude — aurora is rare and requires a major storm.

Fair zone

Mid-latitude — aurora visible only during moderate-to-strong storms.

Good zone

High-latitude region — aurora is visible on most active nights.

Excellent zone

Directly under the auroral oval — aurora is a regular occurrence.

Excellent zone

Kemijärvi is in a prime aurora zone, so aurora can be visible during regular activity when skies are dark and clear.

Frequently Asked Questions

Can you see the Northern Lights in Kemijärvi tonight?

Often, yes. Kemijärvi is at 64.0° geomagnetic latitude, inside the ring where aurora is most frequent, so cloud and darkness decide your night rather than activity.

What Kp index is needed to see the Northern Lights in Kemijärvi?

There is no threshold to clear at 64.0° geomagnetic. Kp describes how far the oval reaches, and Kemijärvi is already inside it, so the number matters less here than cloud and darkness.

What is the best time to see the Northern Lights in Kemijärvi?

Between about 22:00 and 02:00, around magnetic midnight. This far north the limit is daylight: September to March gives dark hours to use, and around midsummer there are none at all.

What are the best months to see the Northern Lights in Kemijärvi?

September to March, with January, February, October, November the strongest stretch — around midsummer Kemijärvi gets no astronomical darkness at all. Activity runs all year and tilts a little higher near the March and September equinoxes, a shift in the odds rather than a promise.

Where is the best place to see the Northern Lights in Kemijärvi?

You can watch from Kemijärvi itself. With this few lights around, a garden or the nearest open field is enough, provided nothing blocks the northern horizon. What matters more here is the moon: a bright one washes out faint aurora, so nights near new moon are the ones to pick.
