You are inside the auroral oval
Capital Region sits far enough northern that quiet conditions are enough. What limits you here is cloud and moonlight, not geomagnetic activity.

The months that actually deliver
Counting only nights that were both stormy enough and dark enough, March, September and October came out ahead in Capital Region. 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 Capital Region viewing season.

What to do with the daylight
Aurora watching is a night job, and in winter that leaves a short, bright day to fill. For a day when the cloud sits low, Kjarvalsstadir, Ásmundur Sveinsson Sculpture Museum and Þjóðminjasafnið are indoors and near by.
Keep the daylight loose: the sky decides the evening, and the forecast can turn within a few hours.

What Kp index do you need to see the aurora borealis in Capital Region?
Kp 3. Capital Region sits at geomagnetic latitude 68.8°, and the auroral oval only reaches that far from the pole once activity hits Kp 3.
When is the best time of year to see the aurora borealis in Capital Region?
March, September 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 Capital Region never gets fully dark, so nothing is visible however strong the storm.
Where can you escape the light pollution near Capital Region?
The centre of Capital Region reads Bortle 9. The nearest sky at Bortle 4 is about 26 km north-east around Kjósarhreppur. On a marginal night that drive matters more than the forecast does.
