What this score means

The 0–100 number is our viewing score, not a percent chance. It combines NOAA signals with NWS clouds, darkness, moonlight and Maine regional thresholds.

Maine Regional Outlook

Northern Maine is one of the best aurora regions in the eastern United States. Dark sky quality is exceptional, but Atlantic cloud cover can erase an otherwise favorable event.

Allagash, Katahdin, or the Downeast coast?

Northern latitude helps in the Allagash, while protected darkness matters around Katahdin. Acadia needs stronger activity and an unusually clear coastal sky.

This is NOAA's current modeled auroral oval, not a live photograph or a promise of visibility. Zoom your eyes toward North America to see how far south the oval reaches.

Maine regional outlook: what the Kp numbers mean

The live cards above use Maine-specific cloud and aurora data. Their Kp values are early planning thresholds, not a promise that lights will be visible. The northern border has the latitude advantage, while Katahdin and the Maine Woods preserve exceptional darkness. Coastal clouds and fog can outweigh both.

Where to watch the northern lights in Maine

These are real locations, not live-confirmed accessible viewing sites. Designated dark-sky land can have exceptionally low light pollution without every point having an independently verified Bortle class. No exact Bortle number is claimed here. Confirm overnight access, road and land restrictions before you go.

Best months and hours for aurora in Maine

September through March generally provides the best combination of early darkness and manageable viewing windows; April can work farther north, while June's late twilight shortens the usable night. Start with 10 p.m.–2 a.m. Eastern Time, but follow NOAA's activity and the local cloud forecast over any fixed clock. A dark, clear night after the moon sets can matter more than a calendar date. Maine's Atlantic coast often has fog; Katahdin roads and Baxter access are highly seasonal.

Aurora photography basics

Mount a camera or phone on a tripod, turn off flash, and focus on a star or distant light. For a camera, start at a wide aperture (around f/2.8), ISO 1600–3200, and a 5–10 second exposure; shorten to 1–3 seconds when the aurora moves quickly. A phone's night mode can capture color that looks faint to the eye if it is held perfectly still. Check the sharpness of stars and keep extra batteries warm. Use a dim red headlamp, and do not walk toward cliffs, water or unmarked trails while composing photos.

Maine northern lights FAQ

How often are northern lights visible in Maine?

Not nightly. Far northern Maine and the Katahdin region have better opportunities during moderate-to-strong geomagnetic activity than Portland or the southern beaches.

What Kp should I watch for in Aroostook?

The local planning trigger is Kp 5 around Presque Isle and Caribou, versus Kp 4 in the farther-north Allagash. A dark, clear sky and aurora oval are still essential.

Is Acadia a good northern-lights spot?

Acadia protects darker coastal sky, but its latitude is lower and ocean fog is common. Seawall and approved night-sky sites can work during stronger storms; do not assume Cadillac Mountain summit is open to overnight parking.

Where can I find the darkest sky in Maine?

Katahdin Woods and Waters is a certified Dark Sky Sanctuary, and AMC Maine Woods is a certified Dark Sky Park. Neither designation guarantees an unobstructed northern horizon or access tonight.

Can I drive to a Katahdin overlook after dark?

Check the NPS road and access notices first. Katahdin Loop Road is unpaved and is not a safe last-minute destination in snow or mud.

How to use this tonight

Allagash is the latitude-first benchmark. Katahdin Woods & Waters adds exceptional protected darkness, while Acadia can work during stronger events when coastal clouds cooperate.

Data and truth boundaries

OVATION is a modeled short-term aurora signal and Kp is broad geomagnetic context. Neither is a sighting probability. Missing values stay missing.
