Aurora Borealis Forecast Tonight
Check whether the northern lights are visible tonight using live Kp index, aurora map data, city-specific thresholds, cloud cover, and geomagnetic storm status in one place.
How to Read an Aurora Borealis Forecast
A useful aurora borealis forecast is not just a green oval on a map. You need three things at the same time: enough geomagnetic activity for your latitude, clear skies, and full darkness. AuroraMe combines those signals into city-level forecasts instead of making you check raw NOAA charts manually.
- Check current activity: use the Northern Lights Tonight page for the live Kp outlook and best viewing window.
- Check where it is visible: open the aurora tracker to see the live aurora map and cities with active visibility.
- Check storm context: use the geomagnetic storm tracker to see if a stronger event is pushing aurora to lower latitudes.

Forecast Guide
Best for learning intent: how Kp, clouds, moonlight, and darkness change your actual odds.
What Changes Your Forecast Most?
Kp Threshold
Tromso or Fairbanks can see aurora around Kp 2. Seattle or Edinburgh often need Kp 5-6. New York or London need a severe storm.
Cloud Cover
Clouds block aurora completely. A weaker storm under clear skies beats a strong storm hidden behind thick cloud.
Darkness Window
Most viewing peaks between 10 PM and 2 AM local time, but Arctic winter can extend the window much earlier.
Storm Strength
During G3-G5 storms, the aurora oval expands south and creates the biggest mid-latitude viewing chances.

9 locationsFrequently Asked Questions
What is the best aurora borealis forecast?
The best aurora borealis forecast combines geomagnetic activity with local cloud cover, darkness, and your latitude. Raw Kp alone is not enough to tell you if aurora will be visible from your exact location.
How accurate is an aurora borealis forecast for tonight?
Short-term forecasts for tonight are usually the most accurate because they use real-time solar wind and NOAA updates. Practical accuracy improves further when you add cloud cover and darkness instead of relying on the aurora oval alone.
What Kp index do I need to see northern lights?
It depends on your magnetic latitude. High-latitude cities may only need Kp 2-3, while mid-latitude cities often need Kp 5-7. City forecast pages on AuroraMe show the threshold for each location.
Where can I check a live aurora map?
You can use the live aurora tracker for the current aurora map and visible-now city list, or open AuroraMe to combine the map with clouds, darkness, and light pollution layers.
What time are northern lights usually visible?
The most common viewing window is between 10 PM and 2 AM local time, when the sky is darkest. In Arctic winter you can sometimes see aurora earlier in the evening.
