Wait for an alert; do not book a week
At Kp 7, Warwick 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 to July
Through those months the sun never falls more than 18° below the Warwick horizon, so the sky never darkens fully. Plan around the darker half of the year.
Getting clear of the light
The sky over Warwick reads Bortle 7. Getting clear of the built-up area makes a visible difference on a marginal night.

The months that actually deliver
Counting only nights that were both stormy enough and dark enough, September, August and November came out ahead in Warwick. 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 Warwick 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. Warwick keeps its fortified past above ground, at Kenilworth Castle, Stoneleigh Motslow Hill and Baginton Castle, and for a day when the cloud sits low, St Johns and Herbert Art Gallery and Museum are indoors and near by.
Keep the daylight loose: the sky decides the evening, and the forecast can turn within a few hours.

Common questions about the aurora borealis in Warwick
Can you see the aurora borealis from Warwick?
Yes. On the last 10.0 years of NOAA Kp records, Warwick had about 2.7 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 Warwick?
Kp 7. Warwick sits at geomagnetic latitude 54.4°, 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 Warwick?
September, August and November. Those months scored highest once both conditions are counted together: geomagnetic activity and enough hours of real darkness. From June to July the sky over Warwick never gets fully dark, so nothing is visible however strong the storm.
Where can you escape the light pollution near Warwick?
The centre of Warwick reads Bortle 7. The nearest sky at Bortle 4 is about 96 km west around Herefordshire. On a marginal night that drive matters more than the forecast does.
Where is the nearest place to Warwick with reliable aurora borealis?
Inverness, United Kingdom — 602 km north-north-west. It needs only Kp 5 and averages 28.7 viable nights a year against 2.7 in Warwick.
