How we calculate the aurora score
LowWe combine geomagnetic activity (Kp), aurora oval probability (OVATION), cloud cover, darkness and moonlight, weighted for New Orleans (region: low_latitude).
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.
Low chance tonight. Aurora may be possible only under very favorable local conditions.
Aurora visibility in New Orleans is low tonight. A stronger geomagnetic storm or better local conditions would improve the chance of seeing the Northern Lights.

Best Viewing Window
10:00 PM – 12:00 AM
Best balance of darkness, geomagnetic activity and local sky conditions.
Direction to Look
North
This location is farther from the auroral oval, so aurora is most likely to appear low on the northern horizon during strong activity.
Recommendation
Check the forecast again later. Aurora conditions can change quickly during geomagnetic activity.

Why this forecast?
There is a low chance of visible aurora tonight. Some conditions may help, but overall the forecast does not strongly support visibility.
Score breakdown
How tonight's aurora score for New Orleans breaks down into activity and visibility components.
?
Geomagnetic activity
0 / 45Geomagnetic activity (Kp 1.7) contribution to the score.

Aurora oval probability
0 / 15OVATION aurora oval probability (0%) contribution.

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. New Orleans needs Kp ≥ 6.
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 New Orleans: expected Kp is 1.7, while this location usually needs around 6.
?
Cloud cover
CloudyAverage 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.
Cloudy
Cloud cover is high tonight, which can block the view even if aurora activity is present.
?
Sky darkness
Astronomical darknessAurora 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.
Astronomical darkness
?
Moon illumination
Moderate moonlightA 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.
Moderate moonlight
Moonlight is moderate tonight and may slightly reduce aurora visibility.
?
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
Low zoneHow favourable New Orleans'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.
Low zone
New Orleans is outside the main aurora zone, so visible aurora usually requires a strong geomagnetic storm.

Best Months to See the Northern Lights in New Orleans
The aurora season in New Orleans usually runs from October to March.
New Orleans sits at 40.01° magnetic latitude, which means aurora typically becomes visible when the Kp index reaches 6.0+. Sightings in this low-latitude region are extremely rare and require significant geomagnetic activity. For the best chance, plan your visit between October and March.
