Wait for an alert; do not book a week
At Kp 7, Courtenay needs a severe geomagnetic storm before anything shows above the northern horizon. Storms that size arrive a handful of times per solar cycle and announce themselves a day or two ahead. Watching for one beats picking dates and hoping.

Nothing to see from June
Through those months the sun never falls more than 18° below the Courtenay horizon, so the sky never darkens fully. Plan around the darker half of the year.
Getting clear of the light
Courtenay is small enough that its own lights are a minor problem — the centre reads Bortle 2. Walking to the edge of town is often escape enough.

The months that actually deliver
Counting only nights that were both stormy enough and dark enough, May, September and August came out ahead in Courtenay. 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 Courtenay viewing season.

Common questions about the aurora borealis in Courtenay
Can you see the aurora borealis from Courtenay?
Yes. On the last 10.0 years of NOAA Kp records, Courtenay had about 3.1 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 Courtenay?
Kp 7. Courtenay sits at geomagnetic latitude 54.8°, and the auroral oval only reaches that far from the pole once activity hits Kp 7. Storms that size occur about 3.2 nights a year.
When is the best time of year to see the aurora borealis in Courtenay?
May, September and August. Those months scored highest once both conditions are counted together: geomagnetic activity and enough hours of real darkness. From June the sky over Courtenay never gets fully dark, so nothing is visible however strong the storm.
Where can you escape the light pollution near Courtenay?
The centre of Courtenay reads Bortle 2. The nearest sky at Bortle 2 is about 7 km north around Area B (Lazo North). On a marginal night that drive matters more than the forecast does.
Where is the nearest place to Courtenay with reliable aurora borealis?
Juneau, United States — 1,137 km north-north-west. It needs only Kp 5 and averages 28.7 viable nights a year against 3.1 in Courtenay.
