Best time to see the northern lights in Yukon, Canada
Updated • 21:02 UTC
Yukon gets the aurora on 68.1 clear nights in a typical year at Dawson City, its strongest of 2 tracked locations. March is the best month at 13.03 of them, and nights were counted at Kp 1 or higher, which the planetary index last reached on 7 September 2026. The count threshold runs from Kp 1 at the northern end to Kp 3 at the southern end.
Typical-year figures: a 1996–2026 planetary Kp record crossed with a 2001–2020 cloud normal. They describe a normal year, not tonight — the live Dawson City forecast shows the actual cloud, moon and darkness right now. Check tonight's forecast for Dawson City →

Astronomical darkness, the nights on which planetary Kp reached Kp 1 inside that darkness, the local cloud normal, and what the cloud leaves of the count.

May, June, July and August never reach astronomical darkness at Dawson City, so no Kp value makes them viewing months and they are excluded rather than scored. The region is not uniform in this: 1 of its 2 tracked locations do get some astronomical darkness in at least one of those months.
Opportunity nights are the whole 1996–2026 record. In the current solar cycle alone (since 2023), March has averaged 30.94 rather than 25.75.
- March: 6.36h of astronomical darkness a night
- March: 25.75 nights reach the Kp threshold inside that darkness
- March: 49.4% mean cloud leaves 13.03 of them clear
- March: 55.3% of those nights are moon-free

Every tracked location in Yukon
All 2 of them, strongest first. The month column is each location's own best month with its clear nights; the Kp is the threshold its live forecast serves.
| Location | Clear nights a year | Best month | Kp needed |
|---|---|---|---|
| Dawson City | 68.1 | March (13.03) | Kp 2 |
| Whitehorse | 23 | February (4.28) | Kp 3 |
How these numbers were made
- Evaluated at
- Dawson City, 64.0607° N 139.4158° W — darkness and cloud are properties of that point, not of a region.
- Darkness
- Sun at or below 18° under the horizon (astronomical twilight), sampled every 10 minutes across every year of the Kp record and averaged per night of each month rather than on one representative day.
- Geomagnetic record
- GFZ Potsdam planetary Kp index, 3-hourly, 1996–2026 — 89,662 intervals, licensed CC BY 4.0.
- Cloud
- NASA POWER 20-year monthly climatology (2001–2020), parameter CLOUD_AMT. A monthly mean, not a forecast.
- Moon
- A night counts as moon-free below 35% lunar illumination while the moon is up.
- Auroral oval
- NOAA auroral-oval model, equatorward boundary near magnetic latitude 67 − 2 × Kp. A model estimate shown beside the measured record; it never replaces it.
- Clear opportunity nights
- Nights on which at least one 3-hour Kp interval falls inside local astronomical darkness and reaches the count threshold, scaled by one minus the monthly mean cloud amount.
- Kp threshold
- Nights were counted per location, from Kp 1 at the northern end to Kp 3 at the southern end of the region; Dawson City counts at Kp 1. The Required Kp shown above, Kp 2, is the threshold the live Dawson City forecast serves.

Frequently Asked Questions
When can you see the northern lights in Yukon?
March is the best month, with 13.03 clear nights in a typical year out of 68.1 across the whole year. Every month except May, June, July and August carries some chance. May, June, July and August never reach astronomical darkness, so no Kp value makes them viewing months.
What Kp is needed to see the aurora from Yukon?
Yukon needs Kp 2 or higher for aurora, Kp 3 for a noticeable display and Kp 4 for a bright one. Across the region that horizon threshold runs from Kp 2 to Kp 3. The NOAA auroral-oval model places the oval overhead at Yukon once the planetary index reaches Kp 1. That is a model estimate; the dates on this page come from the measured Kp record instead.
Has the aurora ever been visible from Yukon?
Yes. In the 1996–2026 planetary Kp record the index reached Kp 1, the threshold these nights were counted at for Yukon, most recently on 7 September 2026. Whether anyone saw it also depended on the cloud, moonlight and darkness of that night, which the Kp record does not carry.
