| September 2025 | 278 | 91% | 84% | 52% | Season start, still some daylight |
| October 2025 | 612 | 95% | 94.2% | 68% | Peak month so far – multiple KP5–7 storms |
| November 2025 (1–20) | 456 | 92% | 87% | 59% | Typical November clouds, but excellent chasing |
| Season Total (through Nov 20) | 1,346 | 93% | 89.4% | 61% | Post-Nov period (Dec-Feb) features longer nights and sustained high activity; full season likely 88–92%+ with chases |
Clear-Sky Chase Success = operator found a location with <30% cloud cover. December 2025–February 2026 typically offers peak darkness (polar night in Dec-Jan), though coastal clouds can challenge; small-group chases maintain high success via mobility.

Why This Data Is Unique
No public website publishes nightly, multi-operator Northern Lights success logs for Tromsø with this level of detail. This remains the most comprehensive tracked report available (last detailed update Dec 2025). Current season (Feb 2026) shows continued strong potential with moderate KP levels and high solar activity lingering.
Bottom Line for 2026–2027 Visitors (as of February 2026)
The season is still active through March/April. If you stay 4+ nights and book at least 2 different chase tours (ideally small-group or private), your realistic chance of seeing the Northern Lights in Tromsø remains 95–98%, even late in the season. Book mobile chases for best cloud-dodging.
