Worth watching through the dark half of the year
Kp 5 is a moderate storm — not an everyday event, but common enough that a patient observer in Kuusamo sees the aurora borealis most winters.

Solar declination and hour angle at −18°
Nothing to see from April to August
Through those months the sun never falls more than 18° below the Kuusamo horizon, so the sky never darkens fully. Plan around the darker half of the year.
Getting clear of the light
Kuusamo is small enough that its own lights are a minor problem — the centre reads Bortle 5. 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, September, March and October came out ahead in Kuusamo. 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 Kuusamo viewing season.

Common questions about the aurora borealis in Kuusamo
Can you see the aurora borealis from Kuusamo?
Yes. On the last 10.0 years of NOAA Kp records, Kuusamo had about 17.2 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 Kuusamo?
Kp 5. Kuusamo sits at geomagnetic latitude 62.6°, 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 Kuusamo?
September, March and October. Those months scored highest once both conditions are counted together: geomagnetic activity and enough hours of real darkness. From April to August the sky over Kuusamo never gets fully dark, so nothing is visible however strong the storm.
Where can you escape the light pollution near Kuusamo?
The centre of Kuusamo reads Bortle 5. The nearest sky at Bortle 4 is about 15 km east-north-east. On a marginal night that drive matters more than the forecast does.
Where is the nearest place to Kuusamo with reliable aurora borealis?
Rovaniemi, Finland — 167 km west-north-west. It needs only Kp 3 and averages 171.4 viable nights a year against 17.2 in Kuusamo.
