Aurora Season Guide

Best Months to See the Northern Lights in the Yukon

Not all nights are equal. Here's what the season actually looks like from Whitehorse.

The Yukon sits directly under the auroral oval — one of the most active aurora zones on Earth. From late August through April, the nights are dark enough to hunt. But the quality of your experience depends heavily on when you go. This guide breaks down each month honestly, so you can plan around your best odds.

August

Good

Late August

Late August is Good for first hunts with short dark windows.

After the midnight sun fades, darkness comes back fast. Late August offers the first real aurora nights of the season. Activity is often surprisingly strong thanks to the autumn equinox effect. Temperatures are mild (0°C to +10°C), making this a comfortable entry point. The downside: nights are still short, giving you a narrower window.

Highlights

  • Mild temperatures
  • First hunts of the season
  • Equinox activity spike
Watch out: Short dark window — only 4–6 hours of true darkness.

September

Excellent

Full month

September is Excellent — the autumn equinox drives a reliable activity peak.

September is one of the best-kept secrets of aurora season. The autumn equinox (around September 22–23) reliably produces some of the most intense geomagnetic activity of the year. Nights are growing longer and temperatures are still manageable (-5°C to +5°C). The boreal forest turns gold, making for stunning photography.

Highlights

  • Autumn equinox geomagnetic peak
  • Comfortable temperatures
  • Fall colours in photos
Watch out: Cloud cover can be unpredictable — we may need to drive to find clear sky.

October

Prime

Full month

October is Prime — long nights, high activity, and crisp clear air.

October marks the start of peak aurora season in the Yukon. Nights run 8–10 hours of darkness. The air is crisp and clear, and geomagnetic activity remains elevated from the equinox. Temperatures drop to -10°C to -20°C — cold enough to require proper layers, but manageable with the right gear. This is when we see some of our most dramatic hunts.

Highlights

  • Long dark nights
  • High geomagnetic activity
  • Clear, dry air
Watch out: Temperatures require thermal layers — we'll send a gear list before your tour.

November

Prime

Full month

November is Prime — up to 14 hours of darkness and some of our most spectacular displays.

November is consistently one of our strongest months. Up to 14 hours of darkness, stable cold air that keeps the sky clear, and aurora activity that can fill the entire sky. Temperatures range from -15°C to -30°C. The cold is real — but so is the reward. Many of our most memorable hunts happen in November.

Highlights

  • Up to 14 hours of darkness
  • Stable clear skies
  • Intense aurora displays
Watch out: Serious cold. Dress in proper expedition layers — we'll guide you.

December

Excellent

Full month

December is Excellent for the longest nights, but extreme cold is the real challenge.

December has the longest nights of the year — up to 16 hours of darkness around the solstice. Aurora activity is solid and the landscape is deeply wintery. The challenge is the cold: -25°C to -40°C is common. We operate through December, but guests need to be prepared for extreme cold. The payoff, when the lights appear over a snow-covered boreal forest, is unforgettable.

Highlights

  • Longest nights of the year
  • Deep winter landscape
  • Solstice atmosphere
Watch out: Extreme cold (-25°C to -40°C). Not recommended for guests who struggle with cold.

January

Good

Full month

January is Good for the dedicated — raw wilderness, very few tourists, and serious cold.

January is the coldest month in the Yukon. Aurora activity is present, but geomagnetic conditions are typically quieter than the equinox months. Very few tourists, long nights, and a raw, silent wilderness experience. Temperatures regularly hit -35°C to -45°C. We run tours in January, but we are selective about conditions and guest preparation.

Highlights

  • Very few tourists
  • Raw wilderness experience
  • Long nights
Watch out: Coldest month of the year. Requires full expedition gear and cold-weather experience.

February

Prime

Full month

February is Prime — geomagnetic activity climbs toward the spring equinox with moderating cold.

February is a hidden gem. Temperatures begin to moderate slightly (-15°C to -25°C). Days are getting longer but nights are still substantial. Geomagnetic activity starts climbing toward the spring equinox. We consistently see strong aurora in February, and the combination of manageable cold and high activity makes it one of our favourite months.

Highlights

  • Moderating temperatures
  • Rising geomagnetic activity
  • Great photography conditions
Watch out: Can still get very cold snaps — always dress for -30°C.

March

Prime

Full month

March is Prime and the best overall month — spring equinox peak, warming temperatures, best photography.

March is arguably the best month of the entire aurora season. The spring equinox (around March 20–21) produces the highest geomagnetic activity of the year. Temperatures are rising (-5°C to -20°C). Days are getting longer and the snow-covered landscape is at its most photogenic. If you can only come once, come in March.

Highlights

  • Spring equinox — highest activity of the year
  • Warming temperatures
  • Best photography conditions
Watch out: Very popular — book early. Only 5 seats per night on The Real Aurora Hunt.

April

Good

Early April

Early April is Good — comfortable temperatures and post-equinox activity, but the season is closing.

Early April still offers real aurora hunting opportunities, especially in the first two weeks. Nights are shortening rapidly, but the post-equinox activity lingers. Temperatures are pleasant (-5°C to +5°C), making this the most comfortable month of the season. By mid-April, nights become too short for reliable hunting.

Highlights

  • Comfortable temperatures
  • Post-equinox activity
  • End-of-season atmosphere
Watch out: Season ends mid-April as nights become too short. Book early in the month.

Aurora activity ultimately depends on solar conditions we cannot predict. What we can control is being in the right place, under clear sky, when the lights appear.
