Best Time to See the Northern Lights in Alaska (Month-by-Month Guide)
There's nothing quite like watching the Northern Lights ripple across an Alaska sky. Whether it's your first time chasing the aurora or you're finally checking it off the bucket list, timing is everything. Alaska offers some of the best Northern Lights viewing in the world, but conditions change a lot depending on the month, the weather, and where you're headed.
Below is a straightforward month-by-month guide to help you plan the perfect aurora adventure—plus a few local tips that make a big difference.
🌌 Why Alaska Is One of the Best Places on Earth for Aurora Viewing
Alaska sits directly under the Auroral Oval, the band of magnetic energy around the poles where aurora activity is strongest. Places like Fairbanks, Talkeetna, and even Anchorage get consistent displays from fall through spring.
If you want the highest chance of seeing the Lights, a guided tour helps a lot. Local guides know cloud patterns, viewing spots, and where the sky tends to open up.

November
Good viewing but unpredictable weather
Snow: Usually starts sticking
Temperatures: Drop quickly
If you don't mind colder nights and the occasional snowstorm, November can deliver great shows.
December
Darkest month of the year
Aurora: Very good when skies are clear
Cons: Cloudy stretches, extreme cold
December has long nights, but clouds can linger. A tour provider that actively relocates to clear skies is your best friend.
January
Deep winter = deep darkness
Aurora: Good; weather starts to improve
Cons: Very cold, very dry
If you're visiting in January, bring the warmest layers you own. The good news? Cold, clear nights are the aurora's best friend.
February ⭐
Top 3 month
Weather: More stable
Nights: Very dark
Viewing chances: High
February is simply excellent. Many travelers choose this month because you get great aurora conditions without brutal early-winter storms.
March ⭐
Peak season
One of the best months overall
Weather: Clearer skies
Daylight: Increasing but still enough darkness
March has a great balance — darker nights, steady weather, and comfortable temperatures. If you want a sure thing, March should be high on your list.
April
Aurora possible: Early April
Skies: Still dark enough until mid-month
Cons: Increasing daylight
April is the tail end of the season. Early April can still produce strong shows, but by the second half of the month, daylight wins the battle.
Best Time of Night to See the Northern Lights
Aurora can appear anytime after dark, but these hours are the sweet spot:
Peak activity: 10 pm – 2 am
Possible: 8 pm – 4 am
If you're going with a tour, guides often track updates in real time so you're not out in the cold longer than needed.
What to Wear on a Northern Lights Tour
Nights can get extremely cold depending on the month. Wear:
Thermal layers
Insulated jacket
Warm boots
Gloves + hat
Hand warmers
