Everyone has a bucket list. For many, witnessing the mesmerising dance of the Northern Lights, also known as Aurora Borealis, across the night sky is a dream that crowns this list. Few places in the world afford better viewing opportunities than Iceland—a land of explosive geysers, bubbling hot springs, majestic waterfalls, and icy glaciers. Let’s delve into when you can marvel at this otherworldly miracle in the land of fire and ice.
The Northern Lights, born from the interaction of solar particles with the Earth’s magnetic field, materialise as striking bands of colour that illuminate the sky, swirling in a spectral ballet of light. These celestial colours predominantly span from fluorescent green and pink to hues of red, yellow, blue, and violet.
Spotting the Northern Lights in Iceland isn’t as simple as looking up at the night sky; several conditions need to align. The primary one is darkness. As this natural phenomenon is solar-powered, excessive daylight dampens its visibility. Hence, the darker the sky, the more vibrant the spectacle—in essence, winter is your key.
Winter in Iceland is from late September to late March, but the darkest months—December to February—are ideal. During this mid-winter period, you have up to 19 hours of darkness per day, massively increasing your chances of spotting these elusive lights. The winter solstice, around December 21st, could be a perfect time, treating viewers to nearly 20 hours of potential viewing.
Darkness alone, however, won’t guarantee an appearance from the elusive Aurora Borealis. Clear skies are a must. As Iceland’s weather can be unpredictable, often with several downpours in a day, it’s crucial to be well-prepared and patient. Always check the forecast beforehand and keep an eye out for dry evenings. Auroras are witnessed more frequently during equinoxes, making September and March particularly good viewing months.
Moreover, to enjoy an unimpeded spectacle, escaping the light pollution from towns and cities is advisable. Locations such as Thingvellir National Park, the Snaefellsnes Peninsula, and the Southern Coast, known for their dark, wide-open spaces and stunning backdrops, are favourite viewing spots among enthusiasts and tour groups.
Solar activity is the penultimate piece of the puzzle. In simpler terms, the more active the sun, the more likely you are to witness the Northern Lights. The kp-index—an indicator of this activity—ranging between 2 to 3 is usually sufficient in Iceland. These solar forecasts, along with real-time Aurora forecasts and alerts, are accessible online.
Lastly, it’s important to manage your expectations. The Northern Lights, while stunning, are notorious for their unpredictability—making them all the more special. On some nights, the lights dance for several hours; on others, they last for mere minutes. They might appear as a conspicuous burst of colours or just a faint glow. The uncertainty, the chase, all adds to the adventure.
To maximise your chances, plan your trip to last for several days, preferably a week. This span allows for fluctuations in weather and solar activity. Touring with experienced Northern Lights tour operators can be highly beneficial. With bucket-list-worthy itineraries and a wealth of local expertise, they can handle the details and improve your chances of gaining this coveted tick on your list.
Experiencing the Northern Lights is an opportunity to witness one of nature’s most enthralling artwork unfold in real-time. And doing so amidst Iceland’s raw, elemental landscapes adds a rugged charm hard to replicate elsewhere. So, wrap up warm, escape to the land of fire and ice and—as the locals say—gangi þér vel with your northern lights adventure.
