Northern Lights in Vermont: Tonight's Aurora Forecast

Q: Can I see the northern lights tonight in Vermont?

Check the live panel on this page: it compares tonight's NOAA forecast Kp with the Kp 5 that Vermont's darkest northern areas need, then folds in tonight's cloud cover and the moon. As a rule, a forecast Kp of 5 or higher with under 40% cloud and a dark northern horizon is worth going out for; below Kp 4 it is not.

Q: What Kp do you need to see the northern lights in Vermont?

About Kp 5 for a display low on the northern horizon from Vermont's darkest northern spots, and roughly Kp 7 for it to climb overhead. Vermont sits near 53° geomagnetic latitude; every ~2° further south adds about one Kp step to what you need.

Q: Where is the best place to see the northern lights in Vermont?

Lake Willoughby, Westmore; Lake Memphremagog, Newport; Isle La Motte, Lake Champlain. The south beach looks straight up the fjord-like lake toward the Northeast Kingdom's darkest sky. The common thread is a dark, unobstructed view to the north — a lakeshore, open prairie, or a summit — well away from city glow.

Q: What is the best time of year to see the northern lights in Vermont?

September, October, November, March, April. Geomagnetic storms cluster around the equinoxes (the Russell–McPherron effect), and the autumn and spring windows combine that with long, dark nights. Deep winter adds the most hours of darkness, often with the clearest air.

Q: What time of night are the northern lights most visible in Vermont?

Usually between 10 pm and 2 am local time, with the most intense substorms often near local magnetic midnight (roughly 11 pm–1 am). Give your eyes 15–20 minutes to adapt, and stay out — displays come in waves separated by quiet half-hours.

Q: Why does the aurora look gray or white to my eyes but green in photos?

At Vermont's latitude the aurora is usually faint and low, and the eye's night vision cannot see color in dim light. A phone in night mode or a camera with a 5–15 second exposure collects far more light and shows the true green (oxygen at ~100 km) and red (oxygen higher up). If you can see a pale, moving arc that is not a cloud, photograph it.

Q: How do I photograph the northern lights with a phone in Vermont?

Use night mode (iPhone) or Night Sight / Pro mode (Android), set exposure to 3–10 seconds, brace the phone on something or use a small tripod, turn the flash off, and point at the darkest part of the northern sky. Tap to focus on a distant light or a star first. Shoot wide and keep shooting — the best frames come during brightenings that last only a minute or two.

Q: How often can you see the northern lights in Vermont?

Several times a year near solar maximum, when the forecast reaches Kp 5 — but you also need a clear, moonless night and a dark northern horizon, which removes most of them. Watch NOAA's 3-day Kp forecast and be ready to drive.

Vermont needs about Kp 5 on the northern horizon. Live NOAA Kp, tonight's cloud cover and moon, the aurora oval map, and the darkest places to watch from.

Can you see the northern lights tonight in Vermont?

The verdict below combines NOAA SWPC's planetary Kp forecast with the Kp 5 that Vermont's darkest northern spots need, tonight's cloud cover from Open-Meteo at Lake Willoughby, 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.

Where to go

Best places to see the northern lights in Vermont

The Northeast Kingdom is the destination. Head for a north-facing lakeshore — Willoughby, Memphremagog, Crystal Lake — and give your eyes 20 minutes. Burlington's waterfront works for Kp 7+ storms, looking across Champlain toward the Adirondacks.

The year, phase by phase

When to see the northern lights in Vermont

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 Vermont this is prime time — a Kp 5 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 Vermont'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 — summer haze and late sunsets make faint displays hard to see. 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 Vermont

3 days out

Watch the NOAA 3-day Kp forecast (the bar strip above). For Vermont, a forecast of Kp 5+ 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 Vermont needs Kp 5

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: Vermont is at about 53° 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 Vermont's darkest northern areas, Kp 5 brings the oval's edge into view on the horizon; Kp 7 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.
