Why this forecast?
Aurora Zone
Higher magnetic latitude = better aurora visibility. Your location's magnetic latitude determines how often auroras appear overhead.
Status Levels:
Perfect Above 62.0° — Excellent aurora visibility (daily activity)
Good 56.0° - 62.0° — Good aurora visibility (regular storms)
Acceptable 50.0° - 56.0° — Fair aurora visibility (strong storms only)
Low Below 50.0° — Poor aurora visibility (extreme storms)
Aurora Zone
Good 56.9°
Kp index
Kp measures global magnetic disturbance. Higher Kp = stronger auroras visible at lower latitudes.
Status Levels:
Storm Kp 6-9 — Geomagnetic storm, strong auroras
Active Kp 3-6 — Moderate activity, good conditions
Quiet Kp 1-3 — Low activity, weak auroras
Very Quiet Kp 0-1 — Very quiet, minimal auroras
Kp index
Quiet 1
Cloud Cover Impact
Clear skies are essential for aurora viewing. Clouds block your view of the northern lights. The percentage shows cloud coverage (0% = clear skies, 100% = overcast).
Status Levels:
Clear Clear (0-25%) — Perfect for aurora viewing
Partly Cloudy Partly Cloudy (26-50%) — May partially block view
Cloudy Cloudy (51-85%) — Significantly blocks aurora
Overcast Overcast (85%+) — Blocks aurora completely
Cloud Cover Impact
☁️ Cloudy 91%
Moonlight
Bright moonlight can wash out faint auroras. New moon provides the darkest skies for optimal viewing.
Status Levels:
New Moon Darkest skies — Best for faint auroras
Crescent Dim moonlight — Good for viewing
Quarter Moderate moonlight — May wash out weak auroras
Gibbous Bright moonlight — Reduces aurora visibility
Full Moon Very bright — Only strong auroras visible
Moonlight
🌒 Crescent 13%
Darkness
Darker skies are essential for aurora viewing. The sun must be below the horizon for auroras to be visible.
Status Levels:
Night Darkest conditions — Optimal for auroras
Astronomical Twilight Dark enough — Good aurora viewing
Nautical Twilight Getting darker — Weak auroras may appear
Daylight Sun is above horizon — No aurora visible

Aurora Borealis Viewing in Sept-Îles
North Shore port city with Gulf of St. Lawrence aurora displays.
Sept-Îles sits at 56.9° magnetic latitude, which means aurora typically becomes visible when the Kp index reaches 6+. Aurora sightings in Sept-Îles require stronger geomagnetic storms (Kp 6+), which occur a few times per year. When storms do hit, the best viewing window is 10 PM to 2 AM local time under clear, dark skies.
Cloud cover is the most common reason people miss aurora even during strong storms. AuroraMe combines the Kp index with real-time cloud forecasts, moon phase, and darkness data to give you a single visibility status — so you know whether it's worth going outside tonight.
For the broader storm picture before checking Sept-Îles, start with the broader forecast hub and the geomagnetic storm tracker. Low-latitude places like Sept-Îles usually need a severe geomagnetic storm, clear northern horizon, and full darkness before northern lights become realistic.

How often can you see northern lights in Sept-Îles?
Based on its magnetic latitude of 56.9°, aurora viewing in Sept-Îles is occasional (10-40 nights per year). We are currently near solar maximum (2024-2025), so expect higher-than-average activity.
Best viewing season: September to March, with peak activity during equinoxes (September and March).
What Kp index do I need to see aurora in Sept-Îles?
For Sept-Îles, you need a minimum Kp index of 6.0 for aurora to be visible. This threshold is calculated based on the city's magnetic latitude (56.9°).
Higher Kp values produce brighter, more active displays:
- Kp 6.0-7.0: Faint aurora visible in dark skies
- Kp 7.0-8.0: Moderate aurora with dancing patterns
- Kp 8.0+: Strong, colorful displays visible even with some light pollution
Current Kp index: 1.0
Where should I look for aurora in Sept-Îles?
Watch the northern horizon. Aurora appears as green or red bands low on the horizon, occasionally rising higher during strong storms.
For best results, seek locations with minimal light pollution and unobstructed views of the sky. From Sept-Îles, aurora typically remains closer to the horizon, so elevated viewing locations help.
Can I see northern lights tonight in Sept-Îles?
Unlikely: Aurora unlikely tonight with Kp 1.0 (below 6.0 threshold for Sept-Îles). Enable alerts to catch future opportunities.
