Is December Really the Best Time to See the Northern Lights or Just a Popular Myth?

Imagine standing under a star-filled sky, the dark canvas illuminated by vibrant greens and purples as the Northern Lights dance above you. Many travelers believe December is the perfect time to witness this breathtaking display. The long, cold nights and festive season create the ideal setting for this natural wonder. However, our experiences in icy locales like Iceland and beyond reveal that this commonly held belief may not tell the whole story. Let’s explore why December is often seen as the best month for viewing the Aurora Borealis, and why other times might be more rewarding.

The Allure of December

December is often seen as the month for experiencing the magic of the Polar Lights. With the holiday spirit in the air, images of friends and families bundled up, watching the sky blanket with shades of green and purple, abound. A common factor that feeds this misbelieve is also the amount of darkness we have in December. During the shortest day of the year (around the 21st of December) in Iceland we only have between 3,5 - 4 hours of daylight. The extended nights of winter provide numerous opportunities for stargazing, while picturesque snowy landscapes add to the charm.

However, the allure of December must be balanced with practical considerations. While it may seem enchanting, it isn't always the best choice for catching a glimpse of the Aurora Borealis.

Solar Activity and the Aurora Forecast

The Northern Lights stem from solar activity. Specifically, they happen when charged particles from the sun interact with Earth’s magnetic field. Thus, the best time to gaze at the lights relies on solar cycles and not just the time of year.

Solar activity follows an approximately 11-year cycle, with peaks called solar maximums. During these times, the chances of spotting the Northern Lights can rise significantly, sometimes doubling or tripling your odds. Scientists are saying we are likely right now or next year in the solar maximum.

Additionally there is an interesting study that shows peak Northern Lights activity during the equinox (the days when we have exactly the same amount of daylight as nighttime, so around September 23rd and March 21st every year). A 75-year study from the NASA solar physicist David Hathaway shows that March has more geomagnetically active days than any other month of the year (with October a close second).

This has to do with the way our earth is tilted, the Russell-McPherron effect — an explanation proposed in 1973 by geophysicists Christopher Russell and Robert McPherron.

Our Earth's axis is aligned parallel to the Sun's axis during the equinoxes, creating optimal conditions for the solar wind's magnetic field to connect with Earth's magnetic field.

There are several websites where you can check data on this phenomenon such as Leirvogur, the magnetic observatory in Iceland, the magnetic observatory of Kyoto or the Space weather prediction center NOAA.

But also for us personally, this is something our own experience has shown us to be true. Of course you can always be lucky pretty much any day (apart from during the summer), but the December idea is a myth.

The Magic of Iceland in Winter

Visiting Iceland in the winter is a treat. While December may not be optimal for Northern Lights viewing, the country still boasts many captivating experiences. From exploring majestic ice caves to unwinding in geothermal hot springs, winter transforms Iceland into a magical landscape.

The contrast of icy terrains against dark night skies creates an unforgettable backdrop for every traveler. Consider enriching your itinerary with activities such as:

• Snowmobiling on glaciers: Experience the thrill of speeding across frozen expanses.

• Hiking in national parks: Discover the wonders of Iceland's unique geology during the day.

• Ice Cave Tours: Experience the natural wonders of Iceland

  
  

These activities complement your quest for the Northern Lights, providing diverse ways to create lasting memories.

Tips for Aurora Hunting

If you are eager to see the Northern Lights, regardless of when you choose to visit, here are some straightforward tips to improve your chances:

1. Stay Updated: Monitor the Aurora forecast and solar activity levels. Use reliable websites or apps that provide real-time insights.

2. Find the Right Spot: Escape city lights and seek out dark areas with clear views of the northern horizon. Prime locations in Iceland include Thingvellir National Park and the Snaefellsnes Peninsula.

   
   

While challenging, planning and patience can lead to the rewards of witnessing this amazing natural display.

Final Thoughts

While December might be the crowd's favorite month for seeking the Northern Lights, it's important to remember that it doesn't guarantee an exceptional experience. Weather, solar activity, and traveler density play significant roles in your success.

Considering alternative months like September and March could enhance your chances of marveling at the Aurora Borealis, while allowing you to enjoy Iceland's captivating winter beauty in March or get the perfect mix between Northern Lights at night and almost still summer during the day in September. So, gather your gear, get ready for adventure, and remember that the Northern Lights await you—just not always in December!

Whether you're an experienced traveler, a photography enthusiast, or someone simply eager to connect with nature, the journey to see the Northern Lights can leave you with unforgettable memories. Happy Aurora hunting!
