How we calculate the aurora score

Moderate

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

With current Kp 5.0 (location needs ≥ 4) and 42% cloud cover, aurora may be visible at Fargo 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 61 /100

Aurora visibility in Fargo is moderate tonight. Northern Lights may be visible if geomagnetic activity holds and local skies remain clear.

With current Kp 5.0 (location needs ≥ 4) and 42% cloud cover, aurora may be visible at Fargo from a dark spot, once your eyes have adjusted.

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 / 4

Geomagnetic activity (Kp index)

Enough 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. Fargo needs Kp ≥ 4.

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.

Enough for this location

Expected Kp 5.0 reaches the 4 that Fargo usually needs, so activity is not what limits the night — cloud, darkness and the moon decide the rest.

•
Cloud cover 47%
?

Cloud cover

Partly cloudy

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.

Partly cloudy

Some clouds are expected, but aurora may still be visible through clear gaps.

✓
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 0%
?

Aurora oval probability (OVATION)

Low

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.

Low

The aurora oval probability is low for this location tonight.

•
Aurora zone Fair zone
?

Aurora zone

Fair zone

How favourable Fargo'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.

Fair zone

Fargo is in an occasional aurora region, so stronger geomagnetic activity is usually needed.

Frequently Asked Questions

Can you see the Northern Lights in Fargo tonight?

Only during a storm. Fargo needs Kp 4 or higher before the oval reaches it, and that happens a handful of nights in a year rather than most weeks. Even then it takes a clear sky, real darkness and a dim moon — cloud blocks aurora at any Kp.

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

Fargo lies at 55.8° geomagnetic latitude — roughly 10° south of the quiet oval's edge — so it takes a geomagnetic storm, Kp 4 or higher, before the ring reaches you, low on the northern horizon rather than overhead.

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

September to April, with January, February, October, November the darkest stretch — though at this latitude the season is set by how often a storm reaches you, not by daylight.

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

Fargo is large enough that its own sky-glow is the main obstacle, so plan on leaving it. Head out away from the lit side until the glow is behind you, and find an open view toward the north — a lake shore, a ridge, anywhere the horizon is not built up. Let your eyes adjust for 20–30 minutes once you are there, and keep the phone screen off.
