Difference Between Aurora Australis and Aurora Borealis
Northern lights are a natural phenomenon produced by solar winds, which blow electronic particles into molecules of atmospheric gases, causing the emission of bright light. While solar activity occurs year-round, there must be dark skies to view auroras, which means the winter months are the time to search for northern lights in Iceland.
What is the Aurora Borealis?
The Aurora Borealis, often called the Northern Lights, occurs in the northern hemisphere, predominantly in regions near the Arctic Circle. This includes countries like Norway, Sweden, Finland, Iceland, Canada, and Alaska.
The northern lights result from charged particles from the sun, mainly electrons and protons, colliding with the Earth’s magnetosphere and interacting with gases in the Earth’s atmosphere. These collisions produce colourful displays of light, primarily in green, red, and purple hues.
What is the Aurora Australis?
The Aurora Australis, also known as the Southern Lights, occurs in the Southern Hemisphere, primarily around the Antarctic Circle. It can be seen in countries such as Australia, New Zealand, Antarctica, and parts of southern South America.
The southern lights have the exact underlying cause as the Northern Lights. Charged particles from the sun interact with the Earth’s magnetic field and atmosphere in the Southern Hemisphere, creating similar colourful light displays.
What Colours are Typical for the Two Natural Phenomenons?
The Aurora Borealis typically appears as curtains, arcs, or swirling light patterns in the night sky in the northern hemisphere. The most common colours are green and white, but red, purple, pink, and blue hues can also be seen.
Meanwhile, the southern lights exhibit similar patterns and colours to the Northern Lights but are observed in the southern hemisphere. Green and pink are the most common colours, but red, purple, and blue can also be visible.
When is the Best Time of Year to See the Northern and Southern Lights?
In the northern hemisphere, the best time to see the Northern Lights is generally from late September to mid-March, when the nights are the longest and darkest.
For the Aurora Australis, the prime viewing season is also from late September to early mid-March, when the nights are the longest and darkest.
What are the Best Countries to View the Northern and Southern Lights?
Visitors often visit countries like Iceland, Norway, Sweden, Finland, Canada, and Alaska for the best viewing opportunities to catch a glimpse of the northern lights.
As for the southern lights, they can be observed in places like Australia, New Zealand, Antarctica, and some parts of South America.

Perlan is home to Iceland’s only planetarium and uses a state-of-the-art 8K projection system and surround sound system to bring you the full spectrum of the magical story of the northern lights.
How do the Northern Lights Form?
The Aurora Borealis is a phenomenon caused by solar winds, which blow electronic particles into molecules of atmospheric gases, causing an emission of bright light. The best time to see northern lights is from September to March, and there are forecasts predicting visibility on the national weather website (www.vedur.is). When the forecast is favourable, it’s best to drive (or take a tour bus) to a dark area and look up.
Does the Aurora Borealis and Aurora Australis look the same?
Seeing the northern and southern lights comes down to the amount of solar activity, cloud cover and intensity. The colours of the Aurora Borealis and Aurora Australis can vary and can appear green, white, red, pink, purple or blue.
How can I increase my chances of seeing northern lights in Iceland?
For an excellent chance to see northern lights in Iceland, travel during the winter, stay for several nights in Iceland, monitor aurora forecasts, join tours, and most importantly, be patient. Sometimes, you may need to wait for the auroras to appear.
How accurate are northern lights forecasts?
The weather frequently changes in Iceland, meaning a favourable northern lights forecast can quickly change if there’s cloud cover. Always check websites and Northern Lights apps right before heading out for a search in Iceland.
