can you see the northern lights when it's cloudy

You generally cannot see the northern lights well when it’s fully cloudy, but you can sometimes see them through thin or broken clouds if the aurora is strong.

Basic answer

  • A completely overcast, thick cloud layer will usually block the aurora from view.
  • Thin, high, or patchy clouds can still let some of the glow through, especially during strong geomagnetic activity.
  • Cameras (long exposure on a DSLR or good phone) can often detect auroras through haze or thin cloud better than the naked eye.

How clouds affect visibility

  • Auroras occur 70–400 km above Earth, far above any weather clouds, but the cloud deck sits between you and the lights like a curtain.
  • A thin or fog-like layer may soften and dim the aurora, reducing the “wow” factor even if you can still see color or movement.
  • With solid low and mid‑level cloud cover, forecasts explicitly note that the spectacle “requires dark and partly clear skies,” meaning your chances drop sharply.

When you still have a chance

  • If forecasts show some breaks or partial cloud, you can see auroras through gaps or where the cloud is thinner, especially in high-activity periods.
  • Cloud layers are often very local; a short drive can take you from overcast to clearer skies and dramatically improve your odds.
  • Even if the forecast looks cloudy, experts recommend not giving up, watching satellite/cloud maps, and being ready to move location.

Practical tips for cloudy nights

  • Check both aurora and cloud-cover forecasts; look for areas with lower cloud and higher activity.
  • Drive away from coastal “moody” weather or local fog into inland or higher, drier areas where skies are often clearer.
  • Go to the darkest possible spot away from city lights, and use a tripod with long exposures to let your camera reveal what your eyes might miss.

Quick takeaway

  • Fully cloudy: chances are very low; you usually need at least partly clear skies.
  • Partly cloudy or thin cloud and strong aurora: you can still see something, though it will be dimmer and less dramatic than under a clear sky.
