# Where to See the Northern Lights in the US and Canada

See the northern lights in the US and Canada: best states, the Kp index, NOAA forecasts, best months, and phone camera tips for aurora photos.

The best places to see the northern lights in the US and Canada are the far-northern latitudes: Alaska, the northern tier of states from Minnesota to Maine, and across Canada from the Yukon and Northwest Territories through the northern provinces. You do not need a trip to Scandinavia. On an active night, a dark, north-facing horizon in Fairbanks, Yellowknife, Voyageurs National Park, or northern Michigan can put the aurora directly overhead, and [NOAA's Space Weather Prediction Center](https://www.swpc.noaa.gov/communities/aurora-dashboard-experimental) publishes free forecasts that tell you exactly when a storm is strong enough to reach your latitude.

## How the Aurora Works and the Kp Index

The aurora borealis happens when charged particles from the solar wind collide with gases in Earth's upper atmosphere, and geomagnetic storms strong enough to push that glow toward the poles' edges (and sometimes much further) are ranked on the planetary K-index, or Kp, a scale from 0 to 9 that NOAA's Aurora Dashboard breaks into bands: Kp 3 is "quiet aurora," Kp 5 is "moderate," Kp 7 is "active," and Kp 9 is "very active" ([spaceweather.gov](https://www.swpc.noaa.gov/communities/aurora-dashboard-experimental)). The Kp value is calculated from a weighted average of K-indices reported by 13 geomagnetic observatories worldwide, and a Kp of 5 or higher marks an official geomagnetic storm ([Wikipedia, K-index](https://en.wikipedia.org/wiki/K-index)).

Each Kp step roughly moves the outer edge of visible aurora several degrees of latitude closer to the equator. NOAA's own G-scale (which maps to Kp) gives a useful rule of thumb for US viewing:

| G-scale | Kp | Typical southern limit in the US |
|---|---|---|
| G1 | 5 | Northern Michigan, Maine |
| G2 | 6 | New York, Idaho |
| G3 | 7 | Illinois, Oregon |
| G4 | 8 to 9 | Alabama, northern California |
| G5 | 9 | Florida, southern Texas |

(Table figures per NOAA's G-scale as summarized on [Wikipedia's K-index page](https://en.wikipedia.org/wiki/K-index).) Alaska, the Yukon, and the Northwest Territories sit directly under the "auroral oval," the ring of peak activity, so they can see a bright display at Kp 2 or 3, long before it becomes visible anywhere in the Lower 48.

## Reading NOAA's Live Aurora Forecast

Before any aurora trip, check [swpc.noaa.gov](https://www.swpc.noaa.gov/products/3-day-forecast) directly rather than relying on a social-media screenshot. NOAA's Space Weather Prediction Center runs three free tools worth bookmarking:

- The **3-Day Forecast** gives predicted Kp values and geomagnetic storm severity for the next three days ([swpc.noaa.gov/products/3-day-forecast](https://www.swpc.noaa.gov/products/3-day-forecast)).
- The **Aurora 30-Minute Forecast** shows a live map of exactly how far south the aurora oval currently extends ([swpc.noaa.gov/products/aurora-30-minute-forecast](https://www.swpc.noaa.gov/products/aurora-30-minute-forecast)).
- The **Aurora Dashboard** combines both into "tonight and tomorrow night" viewlines plus current solar wind conditions ([swpc.noaa.gov/communities/aurora-dashboard-experimental](https://www.swpc.noaa.gov/communities/aurora-dashboard-experimental)).

Watch for a NOAA geomagnetic storm watch or warning (G1 through G5), then cross-reference against your own latitude using the table above.

## Best US States to See the Northern Lights

Alaska is in a class of its own. Fairbanks sits beneath the auroral oval, and its official aurora season runs August 21 through April 21, when it is dark enough to see a display; locals see the aurora on about eight nights out of ten when skies are clear, and visitors who stay three nights or longer have better than 90 percent odds of a sighting ([Explore Fairbanks](https://www.explorefairbanks.com/explore-the-area/aurora-season/)).

Outside Alaska, the northern tier of the Lower 48 is the reliable US zone, needing only a moderate G1 to G2 storm (Kp 5 to 6):

| State | Good aurora spots | Notes |
|---|---|---|
| Alaska | Fairbanks, Denali, Utqiagvik | Aurora season Aug. 21 to Apr. 21; visible most clear nights ([Explore Fairbanks](https://www.explorefairbanks.com/explore-the-area/aurora-season/)) |
| Minnesota | [Voyageurs National Park](https://darksky.org/places/voyageurs-national-park-dark-sky-park/), [Boundary Waters Canoe Area Wilderness](https://darksky.org/places/boundary-waters-canoe-area-dark-sky-sanctuary/) | Voyageurs is a certified Dark Sky Park that promotes itself for aurora viewing ([NPS](https://www.nps.gov/voya/index.htm)) |
| Michigan | [Keweenaw Dark Sky Park](https://darksky.org/places/keweenaw-michigan-dark-sky-park/), Headlands | Upper Peninsula's high latitude and low light pollution make it one of the best Midwest options |
| Maine | Northern Maine woods, Acadia region | Reaches G1-level visibility (Kp 5) per NOAA's G-scale |
| Montana, North Dakota | Glacier National Park area, prairie skies | Wide-open, low-light-pollution horizons for a G2-level (Kp 6) show |
| Idaho, New York | Northern Idaho panhandle, Adirondacks | Typical G2 (Kp 6) southern limit per NOAA |
| Washington, Wisconsin | North Cascades, Lake Superior shore | Occasional displays during G2-plus storms |

## Best Places in Canada: Yukon, the Northwest Territories, and the Northern Provinces

Canada's best aurora country runs from the Yukon and Northwest Territories across the northern edges of the provinces:

| Region | Good aurora spots | Season and notes |
|---|---|---|
| Northwest Territories | Yellowknife, [Wood Buffalo National Park](https://en.wikipedia.org/wiki/Wood_Buffalo_National_Park) (AB/NWT border) | Yellowknife sits directly under the auroral oval; fall season mid-August to late September, winter season mid-November to early April, with up to 240 active-aurora nights a year and a 98 percent chance of seeing the lights over any three-night stay ([Spectacular NWT](https://spectacularnwt.com/story/the-northern-lights-by-the-numbers/)) |
| Yukon | Whitehorse and surrounding wilderness | Aurora season runs mid-August to mid-April, split into an autumn window (mid-August to mid-October) and a winter window (mid-October to early April); best viewing is 10 p.m. to 3 a.m. on clear, moonless nights ([Travel Yukon](https://www.travelyukon.com/en/media/northern-lights)) |
| Alberta | [Wood Buffalo National Park](https://parks.canada.ca/pn-np/nt/woodbuffalo), [Jasper National Park](https://en.wikipedia.org/wiki/Jasper_National_Park) | Wood Buffalo is the world's largest Dark-Sky Preserve, straddling the Alberta/NWT border at nearly 60°N |
| Manitoba, Ontario, Quebec | Northern Manitoba (Churchill area), Lake Superior Provincial Park, Mont-Tremblant | Farther south than the territories but still well north of the US border, with regular displays during moderate storms |
| New Brunswick, Newfoundland and Labrador | Mount Carleton Provincial Park, Terra Nova National Park | Atlantic Canada's darkest, most northerly provincial parks catch strong storms reaching the Maritimes |

## Best Months and Time of Night

Aurora activity itself does not have a season, but darkness does, and the equinoxes tend to line up with more geomagnetic storm activity, making late August through April the practical viewing window across Alaska, the Yukon, and the NWT ([NOAA SWPC](https://www.spaceweather.gov/content/tips-viewing-aurora)). Within any clear night, the strongest displays cluster within an hour or two of local midnight, generally 10 p.m. to 2 a.m. ([NOAA SWPC](https://www.spaceweather.gov/content/tips-viewing-aurora)). A full moon washes out fainter aurora even though it does not weaken the storm itself, so check the [moon phase](/moon) for your travel dates and aim for a new moon or crescent when you can.

## Solar Cycle 25: The 2026 to 2028 Outlook

We are currently past the peak of Solar Cycle 25. NOAA's Space Weather Prediction Center places the cycle's maximum around July 2025, plus or minus eight months, which means elevated solar activity and a good chance of aurora-producing storms continues through 2026 and 2027 before gradually declining through 2028 ([NOAA SWPC, Solar Cycle 25 forecast update](https://www.swpc.noaa.gov/news/solar-cycle-25-forecast-update)). Practically, that means the next two to three years remain some of the best in over a decade for aurora chances at mid-latitudes, even as the long-term trend points toward quieter skies later in the decade. Check the [events calendar](/events) for the current outlook alongside meteor showers, eclipses, and full moons that might compete with or complement an aurora trip.

## Phone Camera Tips for Photographing the Aurora

You do not need a dedicated camera to bring home aurora photos. Modern phones can capture surprisingly good shots with a few adjustments ([AccuWeather](https://www.accuweather.com/en/space-news/how-to-photograph-aurora-lights-on-your-phone/1854341)):

- **Stabilize the phone.** Use a tripod, or brace it on a car roof, fence post, or rock. Any shake ruins a multi-second exposure.
- **Turn off the flash** and clean the lens first.
- **Tap to focus on the sky**, not on trees or foreground objects, and avoid zooming, which cuts the light the sensor receives.
- **On an iPhone (12 or newer):** Night Mode should engage automatically in the dark (look for the yellow moon icon); tap the arrow at the top of the screen and slide the Night Mode exposure slider up to 10 to 30 seconds for a brighter capture.
- **On a Samsung Galaxy S or Ultra phone:** switch to Pro Mode, set ISO to 800 to 1600, shutter speed to 5 to 10 seconds, manual focus to infinity, and use a 2-second timer to avoid shake.
- **Shoot several frames.** Aurora brightens and fades quickly, and one exposure rarely captures the best moment.
- **Add foreground.** A treeline, mountain, or parked car gives the photo scale and makes it more shareable.
- **Keep the phone warm** between shots. Cold weather drains batteries fast in Alaska, the Yukon, and the NWT.

## Planning Your Aurora Trip

Pick a date range using the Solar Cycle 25 outlook above, then narrow it with NOAA's [3-day forecast](https://www.swpc.noaa.gov/products/3-day-forecast) once you are within a week of travel. Choose a base near one of the certified [dark-sky parks](/dark-sky-parks) listed above so light pollution is not working against you, and build in at least two or three nights, since even NOAA's Fairbanks and Yellowknife statistics assume more than one attempt. Layer warm clothing (northern winters run well below freezing), bring a headlamp with a red-light mode to protect your night vision, and pack a phone battery pack for the cold-weather drain noted above. If the aurora forecast is quiet on a given night, many of these same northern parks and preserves are also excellent for [stargazing](/stargazing-for-beginners) or, depending on the calendar, a [meteor shower](/meteor-showers) peak, so check the full [places directory](/places) for backup options near your route.

## Quick answers

**What Kp index do I need to see the northern lights?** From the northern US states you generally need Kp 5 to 6 (a G1 to G2 storm); from Alaska, the Yukon, or the Northwest Territories, Kp 2 to 3 is often enough because those regions sit under the auroral oval ([NOAA SWPC](https://www.swpc.noaa.gov/communities/aurora-dashboard-experimental)).

**When is the best time of year to see the aurora in Alaska?** Fairbanks' aurora season runs August 21 through April 21, when the sky is dark enough; the aurora itself is active year-round but invisible during Alaska's bright summer nights ([Explore Fairbanks](https://www.explorefairbanks.com/explore-the-area/aurora-season/)).

**Can you see the northern lights from the continental US (Lower 48)?** Yes, during moderate to strong geomagnetic storms. A G1 storm (Kp 5) can reach northern Michigan and Maine, and a G2 (Kp 6) can reach New York and Idaho ([Wikipedia, K-index](https://en.wikipedia.org/wiki/K-index)).

**How far south has the aurora been seen?** During the strongest storms on NOAA's scale, a G5 event (Kp 9) can push visible aurora as far south as Florida and southern Texas ([Wikipedia, K-index](https://en.wikipedia.org/wiki/K-index)).

**Do you need a camera to see the aurora, or can you see it with your eyes?** No camera is required; a strong display is easily visible to the naked eye. A phone camera on night mode simply captures color and detail that can look more vivid than what the eye perceives in dimmer shows ([AccuWeather](https://www.accuweather.com/en/space-news/how-to-photograph-aurora-lights-on-your-phone/1854341)).

**What is the Kp index, exactly?** It is NOAA's 0-to-9 planetary geomagnetic activity scale, calculated from a weighted average of readings at 13 mid-latitude observatories worldwide; a value of 5 or higher marks an official geomagnetic storm ([Wikipedia, K-index](https://en.wikipedia.org/wiki/K-index)).
