Northern lights in Tromsø: which night?
Short answer: The darkest, most moon-free nights in Tromsø over the next 30 days are 6 Nov, 7 Nov, 8 Nov, 9 Nov. Aurora also needs clear skies and enough geomagnetic activity (about Kp 1 or more here), which can only be forecast about three days ahead.
Under the auroral oval; most clear nights from September to March show some aurora. Coastal weather changes fast, so chase tours drive to clear skies.

Tromsø northern lights by month
Questions
When is the best time to see the northern lights in Tromsø?
From September to March, on clear nights with little moonlight. The hours around local midnight are usually best. Under the auroral oval; most clear nights from September to March show some aurora. Coastal weather changes fast, so chase tours drive to clear skies.
What Kp do you need to see the aurora in Tromsø?
Tromsø sits under the auroral oval, so even Kp 1 can show aurora on a clear night; Kp 3 or more often brings it overhead.
Does the full moon stop you seeing the northern lights?
No, strong aurora is visible under a full moon, but faint displays and photos are much better on dark, moonless nights.
Darkness means the sun is more than 12° below the horizon. The score weighs dark hours and moonlight; it cannot include clouds or solar activity. Times are local (Europe/Oslo).
