At Tromsø's latitude the sun never drops far enough below the horizon in July for the sky to go properly dark. Aurora may well be happening overhead — you just cannot see it against a bright sky.

If your dates are fixed to July, no viewing spot or tour can fix the physics. Shift the trip toward the season edges instead — late August at the earliest, or spring before the light returns.

Numbers come from 1996–2025 Kp records (GFZ Potsdam) and 2015–2024 hourly cloud history for Tromsø itself — the full method is on the methodology page. Travelling soon? Check tonight's live Tromsø forecast.
