Wait for an alert; do not book a week

Nothing to see from June
Through those months the sun never falls more than 18° below the Townline horizon, so the sky never darkens fully. Plan around the darker half of the year.
Getting clear of the light
Townline is small enough that its own lights are a minor problem — the centre reads Bortle 6. 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 Townline. 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 Townline viewing season.

What Kp index do you need to see the aurora borealis in Townline?

When is the best time of year to see the aurora borealis in Townline?
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 Townline never gets fully dark, so nothing is visible however strong the storm.
