How we calculate the aurora score
UnlikelyWe combine geomagnetic activity (Kp), aurora oval probability (OVATION), cloud cover, darkness and moonlight, weighted for Finland (region: auroral_oval).
With current Kp 1.7 (location needs ≥ 3) and 96% cloud cover, aurora viewing is unlikely at Finland.
Score 0–19. Conditions strongly limit aurora visibility.
Score 20–44. A faint aurora is possible only under perfect conditions.
Score 45–64. Aurora may be visible to alert observers in dark, clear skies.
Score 65–84. A good chance of a visible aurora display.
Score 85–100. Excellent odds — plan to be outside tonight.
Aurora viewing is unlikely tonight.
Aurora visibility in Finland is unlikely tonight. Current conditions do not strongly support visible Northern Lights.
With current Kp 1.7 (location needs ≥ 3) and 96% cloud cover, aurora viewing is unlikely at Finland.

Best Viewing Window
12:00 AM – 2:00 AM
This is the best available window, but geomagnetic activity is expected to be low.
Direction to Look
Overhead or north
This location is close to the auroral oval, so aurora may appear overhead during stronger activity.
Recommendation
Check the forecast again later. Aurora conditions can change quickly during geomagnetic activity.

Why this forecast?
The forecast is unlikely because one or more key conditions are not favorable for visible aurora tonight.
Score breakdown

Geomagnetic activity (Kp index)
Below thresholdKp measures how disturbed Earth's magnetic field is on a 0–9 scale. Higher Kp pushes the aurora oval toward the equator. Finland needs Kp ≥ 3.
Kp is below the minimum needed at this latitude.
Kp is close to the minimum needed — a faint aurora may appear low on the horizon.
Kp meets the threshold for visible aurora here.
Kp is comfortably above the local threshold.
Storm-level Kp ≥ 5 — aurora can be seen far south of its usual zone.
Below threshold
Geomagnetic activity is below the usual visibility threshold for Finland: expected Kp is 1.7, while this location usually needs around 3.
?
Cloud cover
OvercastAverage cloud cover during the best viewing window. Clear skies are essential — even thin overcast hides the aurora.
Up to 25% cloud — excellent visibility.
25–50% cloud — aurora may peek through gaps.
50–85% cloud — most of the sky is blocked.
Over 85% cloud — aurora effectively hidden.
Overcast
Cloud cover is high tonight, which can block the view even if aurora activity is present.
?
Sky darkness
Nautical twilightAurora is faint and needs a dark sky. Astronomical darkness (sun more than 18° below horizon) is ideal.
Sun stays above 6° below horizon all night — no aurora-friendly darkness.
Sun 6–12° below horizon — too bright for faint aurora.
Sun 12–18° below horizon — sky is dark but not fully astronomical.
Sun more than 18° below the horizon — fully dark sky.
Nautical twilight
?
Moon illumination
Bright moonA bright moon washes out faint aurora colours. New moon is ideal; full moon hides everything but the strongest displays.
Less than 25% illuminated — minimal interference.
25–75% illuminated — faint aurora may be washed out.
Over 75% illuminated — only strong displays will be visible.
Bright moon
Moon is 80% illuminated — expect washed-out faint aurora.
?
Aurora oval probability (OVATION)
LowNOAA's OVATION model estimates the chance of aurora visible overhead within a 250 km radius of you.
Less than 5% probability — aurora unlikely to reach this location.
5–20% probability — aurora possible.
20–40% probability — aurora likely if skies are clear.
Over 40% probability — aurora very likely overhead.
Low
The aurora oval probability is low for this location tonight.
?
Aurora zone
Excellent zoneHow favourable Finland's latitude is for aurora viewing in general — independent of tonight's conditions.
Lower latitude — aurora is rare and requires a major storm.
Mid-latitude — aurora visible only during moderate-to-strong storms.
High-latitude region — aurora is visible on most active nights.
Directly under the auroral oval — aurora is a regular occurrence.
Excellent zone
Finland is in a prime aurora zone, so aurora can be visible during regular activity when skies are dark and clear.

Best Months to See the Northern Lights in Finland
The aurora season in Finland usually runs from September to April.
Finland is located in the auroral oval region, which means auroras can often become visible when the Kp index reaches around 3 or higher. The best chances usually come during the darkest months of the season, with clear skies and low light pollution.
