The University of Alaska Fairbanks Geophysical Institute, which runs the state's aurora forecast, estimates Fairbanks visitors who stay three clear nights have about a 90% chance of seeing the aurora.

Can you see the northern lights tonight in Alaska?

The verdict below combines NOAA SWPC's planetary Kp forecast with the Kp 2 that Alaska's darkest northern spots need, tonight's cloud cover from Open-Meteo at Chena Lakes Recreation Area, the moon, and the hours of full darkness. Then each city and dark-sky site gets its own cloud reading — the sky often clears inland when the lakeshore or coast is socked in.

The aurora oval over Alaska right now

NOAA's OVATION model maps where aurora is likely overhead in the next 30–90 minutes. Green cells mean a small chance, red a strong one. The map opens on Chena Lakes Recreation Area; enter a ZIP to recenter, and widen the span to see the whole oval across Canada.

Where to go

Best places to see the northern lights in Alaska

Fairbanks sits directly under the auroral oval — on a clear night between late August and mid-April, the odds of seeing something are better than 80% if you stay out from 10 pm to 2 am. Anchorage needs Kp 3+; Juneau Kp 4+. The best of the year is late February through March: long nights, less cloud.

The year, phase by phase

When to see the northern lights in Alaska

JanFebMarAprMayJunJulAugSepOctNovDec

September – November autumn season

The equinox weeks around September 22 are statistically the most geomagnetically active of the year, and nights are long again. In Alaska this is prime time — a Kp 2 night shows an arc on the northern horizon, and clear, dry autumn air helps.

December – February long dark nights

Fewer storms than the equinoxes but 14+ hours of darkness and often the clearest, driest air of the year. Dress for it — the best displays come after midnight.

March – April spring season

The March equinox brings the second annual peak in geomagnetic storms. Nights are still long in March, and Alaska's snow cover makes the landscape glow under even a faint display. By late April the late sunsets start to cut into viewing time.

May – August short nights

Short nights and twilight — in the far north there is barely any full darkness in June. Big storms still punch through: NOAA rated the 10–11 May 2024 event G5, the top of its scale, and it was seen across most of the lower 48.

Field guide

How to see — and photograph — the aurora from Alaska

3 days out
Watch the NOAA 3-day Kp forecast (the bar strip above). For Alaska, a forecast of Kp 2+ is the trigger. Coronal-hole high-speed streams give 2–3 days' notice; a coronal mass ejection arrives 1–3 days after it leaves the Sun.
Day of
Check tonight's cloud cover and the moon here, then pick the clearest of the sites above. A bright moon will not stop a strong display but washes out a faint one — favor the week around new moon when you have the choice.
After dark
Get a dark, open northern horizon — a lakeshore, a ridge, open farmland — 30+ miles from city glow. Turn off the headlights, give your eyes 20 minutes, and look for a pale arc or moving patches low in the north that are not cloud. Stay 10 pm–2 am; activity comes in waves.
Phone settings
iPhone: Night mode, set to 10 s (30 s on a tripod), flash off, brace the phone. Android: Night Sight or Pro mode, ISO 1600–3200, 5–15 s, manual focus at infinity. Camera: widest lens, f/2.8 or faster, ISO 1600–6400, 3–10 s — shorter as the display brightens and moves.

Why Alaska needs Kp 2

Kp, geomagnetic latitude, and solar cycle 25

The aurora forms in an oval around the geomagnetic pole, which sits over northern Canada rather than at the geographic pole. That tilt is why the eastern United States is magnetically "further north" than the West: Alaska is at about 65° geomagnetic latitude. The planetary K-index (Kp, 0–9) measures how disturbed Earth's magnetic field is; as Kp rises, the oval expands toward the equator by roughly 2° of latitude per step. From Alaska's darkest northern areas, Kp 2 brings the oval's edge into view on the horizon; Kp 4 puts it overhead.

NOAA's G-scale is a simpler label on the same thing: G1 (Kp 5) minor, G2 (Kp 6) moderate, G3 (Kp 7) strong, G4 (Kp 8) severe, G5 (Kp 9) extreme. Solar cycle 25 reached its maximum in 2024–2025 — NOAA rated the 10–11 May 2024 storm G5, the top of its scale — and the declining phase of a cycle historically produces the biggest individual storms, so 2026 and 2027 remain good years to watch. Storms also cluster near the equinoxes, which is why September–October and March–April are "aurora season" everywhere in the lower 48.
