Best time to see the northern lights in Akutan, Alaska

Akutan gets under one clear night a year — 0.1 in a typical year. Only an extreme storm brings the aurora within reach: aurora needs Kp 7 or higher, which the planetary index last reached on 21 January 2026. November carries the most of that thin history, at 0.03 clear nights in a typical year, which is not a month worth booking.

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 Akutan forecast shows the actual cloud, moon and darkness right now. Check tonight's forecast for Akutan →

June never reach astronomical darkness at Akutan, so no Kp value makes them viewable there and they are excluded rather than scored.

Opportunity nights are the whole 1996–2026 record. In the current solar cycle alone (since 2023), November has averaged 0.27 rather than 0.33.

November: 11.33h of astronomical darkness a night
November: 0.33 nights reach the Kp threshold inside that darkness
November: 89.8% mean cloud leaves 0.03 of them clear
November: 54.3% of those nights are moon-free

How these numbers were made

Evaluated at: Akutan, 54.14° N 165.763° 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)

Frequently asked questions

When can you see the northern lights in Akutan?

There is no season for it. Akutan averages 0.1 clear nights of aurora a year across the 1996–2026 Kp record, so the answer is whenever an extreme storm happens to fall on a dark, clear night. November holds the most of that history, at 0.03 clear nights in a typical year. Watch the live forecast rather than the calendar.

What Kp is needed to see the aurora from Akutan?

Akutan needs Kp 7 or higher for aurora on the northern horizon, Kp 8 for a noticeable display and Kp 9 for a bright one. The NOAA auroral-oval model puts the edge of the oval about 67.6° above the northern horizon at Akutan at Kp 7. That is a model estimate, separate from the measured Kp record.

Has the aurora ever been visible from Akutan?

Yes. In the 1996–2026 planetary Kp record the index reached the horizon threshold for Akutan, Kp 7, most recently on 21 January 2026, and the Kp 8 needed for a noticeable display on 1 January 2025. Whether anyone saw it also depended on the cloud, moonlight and darkness of that night, which the Kp record does not carry.
