Best time to see the northern lights in Alaska
Alaska gets aurora on 75.9 clear nights in a typical year at Venetie, its strongest of 212 tracked locations. January is the best month at 14.48 of them, and aurora needs Kp 1 or higher, which the planetary index last reached on 7 September 2026. The threshold rises to Kp 8 at the southern end of the state, against Kp 1 at Venetie.
These are 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 Venetie forecast shows the actual cloud, moon and darkness right now. Check tonight's forecast for Venetie →

Astronomical darkness, the nights on which planetary Kp reached Kp 1–8 inside that darkness, the same count over the current solar cycle alone, and what the local cloud normal leaves of the long-run figure.

May, June, July and August never reach astronomical darkness at Venetie, so no Kp value makes them viewable there and they are excluded rather than scored. The state is not uniform in this: 153 of its 212 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), January has averaged 31.76 rather than 27.47.
- January: 12.28h of astronomical darkness a night
- January: 27.47 nights reach the Kp threshold inside that darkness
- January: 47.3% mean cloud leaves 14.48 of them clear
- January: 53.4% of those nights are moon-free

How these numbers were made
- Evaluated at
- Venetie, 67.0083° N 146.3667° W — darkness and cloud are properties of that point, not of a region.
- Darkness
- sun geometric altitude at or below -18 degrees (astronomical twilight). 10-minute samples across every year of the Kp record (1996-2026), averaged per night of each month rather than sampled on one representative day.
- Geomagnetic record
- GFZ Potsdam planetary Kp index, 3-hourly, 1996-01-01 to 2026-09-07 — 89,661 intervals, licensed CC BY 4.0.
- Cloud
- NASA POWER SYN1DEG 20-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 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 estimate, reported separately. The figure for this location is above, beside the measured record it never replaces.
- Clear opportunity nights
- clear opportunity nights = nights on which at least one 3-hour Kp interval falls inside local astronomical darkness and reaches the location’s horizon threshold, scaled by (1 - monthly mean cloud amount)
- Dataset version
- Version 2026-09-07, computed offline by seo-ops scripts/aurora-usa-best-time-data.ts.
The same dataset for every tracked city and state is published at US Aurora Season Climatology, and how the live forecast is built is on the methodology page. Kp record: GFZ Potsdam (CC BY 4.0). Cloud normal: NASA POWER.
Frequently asked questions
When can you see the northern lights in Alaska?
January is the best month, with 14.48 clear nights in a typical year out of 75.9 clear nights across the whole year. Every month except April, 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 Alaska?
Alaska needs Kp 1 or higher for aurora on the northern horizon, Kp 2 for a noticeable display and Kp 3 for a bright one. Across the state that horizon threshold runs from Kp 1 in the north to Kp 8 in the south. The NOAA auroral-oval model places the oval overhead at Alaska 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 Alaska?
Yes. In the 1996–2026 planetary Kp record the index reached the horizon threshold for Alaska, Kp 1, most recently on 7 September 2026, and the Kp 2 needed for a noticeable display on 30 March 2026. Whether anyone saw it also depended on the cloud, moonlight and darkness of that night, which the Kp record does not carry.
