The months that actually deliver
Counting only nights that were both stormy enough and dark enough, September, August and November came out ahead in Royal Leamington Spa. 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 Royal Leamington Spa 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. Royal Leamington Spa keeps its fortified past above ground, at Stoneleigh Motslow Hill, Kenilworth Castle and Baginton Castle, and for a day when the cloud sits low, Herbert Art Gallery and Museum, Coventry Transport Museum and St Johns 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 Royal Leamington Spa?
