Best chance in Iowa: Cedar Rapids
Free push alerts built on NOAA space weather data, plus the 72-hour forecast, cloud cover and darkness window for Cedar Rapids.
Northern lights in Iowa are rare: they need a geomagnetic storm of Kp 8 or more to reach this far south. AuroraMe tracks 2 locations across Iowa, all at Kp 8; Cedar Rapids has the highest magnetic latitude.

Best Viewing Season in Iowa
In a typical year no location we track in Iowa records a single clear night with Kp at its threshold. Only an extreme geomagnetic storm brings aurora this far south. Kp last reached the local threshold on 2025-11-12. Figures below are for Cedar Rapids, the best-placed of the 2 locations we track in Iowa. They describe a typical year built from the 1996-2026 planetary Kp record and the 2001-2020 cloud normal — not a forecast. Each city page shows tonight's live cloud, moon and darkness instead.

That oval line is a model estimate of where the aurora sits at extreme Kp, not a measurement — the threshold date above comes from the Kp record itself.
Frequently Asked Questions
Can you see the northern lights in Iowa?
No — not in a typical year. Iowa averages under one clear night with the aurora in reach, and the planetary index has to reach Kp 8+ for it to be visible at all, which last happened on 2025-11-12. Only an extreme geomagnetic storm brings the aurora this far south, so this is a watch-the-alerts situation rather than a month to plan around.
