Why this forecast?
Aurora Zone
Higher magnetic latitude = better aurora visibility. Your location's magnetic latitude determines how often auroras appear overhead.
Status Levels:
Kp index
Kp measures global magnetic disturbance. Higher Kp = stronger auroras visible at lower latitudes.
Status Levels:
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:
Moonlight
Bright moonlight can wash out faint auroras. New moon provides the darkest skies for optimal viewing.
Status Levels:
Darkness
Darker skies are essential for aurora viewing. The sun must be below the horizon for auroras to be visible.
Status Levels:

Aurora is Rare in Idaho Falls — But Not Impossible
Aurora Borealis Viewing in Idaho Falls
Eastern Idaho city with clear high-desert skies for northern lights.
Idaho Falls sits at 50.7° magnetic latitude, which means aurora typically becomes visible when the Kp index reaches 8+. Aurora sightings in Idaho Falls require stronger geomagnetic storms (Kp 8+), 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 Idaho Falls, start with the broader forecast hub and the geomagnetic storm tracker. Low-latitude places like Idaho Falls usually need a severe geomagnetic storm, clear northern horizon, and full darkness before northern lights become realistic.

Northern Lights in Idaho Falls: Quick Guide
How often can you see northern lights in Idaho Falls?
Based on its magnetic latitude of <strong>50.7°</strong>, aurora viewing in Idaho Falls is <strong>rare (5-15 nights per year, mainly during strong storms)</strong>. 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 Idaho Falls?
For Idaho Falls, you need a minimum Kp index of <strong>8.0</strong> for aurora to be visible. This threshold is calculated based on the city's magnetic latitude (50.7°).
Higher Kp values produce brighter, more active displays:
- Kp 8.0-9.0: Faint aurora visible in dark skies
- Kp 9.0+: Strong, colorful displays visible even with some light pollution
Current Kp index: 3.3
Where should I look for aurora in Idaho Falls?
Aurora is rarely visible this far south. When it does appear during extreme storms (Kp 7+), look for a faint glow on the northern horizon.
For best results, seek locations with minimal light pollution and unobstructed views of the sky. From Idaho Falls, aurora typically remains closer to the horizon, so elevated viewing locations help.
Can I see northern lights tonight in Idaho Falls?
Unlikely: Aurora unlikely tonight with Kp 3.3 (below 8.0 threshold for Idaho Falls). Enable alerts to catch future opportunities.
