The months that actually deliver
Counting only nights that were both stormy enough and dark enough, September, March and October came out ahead in Cumbernauld. That is storm season and darkness overlapping — the equinoxes tend to be geomagnetically active, and the nights are already long by then.
Darkest nights of the coming year
A bright moon washes out a weak display as effectively as street lighting. These new moons fall inside the Cumbernauld viewing season.

Common questions about the aurora borealis in Cumbernauld
Can you see the aurora borealis from Cumbernauld?
Yes. On the last 10.0 years of NOAA Kp records, Cumbernauld had about 22.6 nights a year when the storm was strong enough and the sky dark enough at the same time.
What Kp index do you need to see the aurora borealis in Cumbernauld?
Kp 5. Cumbernauld sits at geomagnetic latitude 58.3°, and the auroral oval only reaches that far from the pole once activity hits Kp 5. Storms that size occur about 28.7 nights a year.
When is the best time of year to see the aurora borealis in Cumbernauld?
September, March and October. Those months scored highest once both conditions are counted together: geomagnetic activity and enough hours of real darkness. From May to July the sky over Cumbernauld never gets fully dark, so nothing is visible however strong the storm.
Where can you escape the light pollution near Cumbernauld?
The centre of Cumbernauld reads Bortle 7. The nearest sky at Bortle 4 is about 37 km north-north-west around Stirling. On a marginal night that drive matters more than the forecast does.
