You never know what you might see when you look up in Lapland!

From the shimmering Aurora Borealis to the endless glow of the Midnight Sun, from the soft shades of polar night to haloed sun dogs, the skies in this land at the top of the world are full of wonder. 

In winter the Northern Lights illuminate dark skies, while in summer the Midnight Sun turns the night white. Other Arctic phenomena and optical illusions can be spotted here too.

Many of these are caused by a combination of the freezing weather, temperature inversion, atmospheric composition, and magnetic field activity that are found in high-latitude regions like Lapland.

Here we share some of the sky spectacles you might see on a visit with us, along with the science and magic of what makes them so special!

Northern Lights

A luminous glow most visible on dark winter nights, the Northern Lights typically appear as wavy arcs, bands, coronas or curtains in colours of green, purple, pink and red. In the Northern Hemisphere, they are known as Aurora Borealis, but they also have a counterpart in the Southern Hemisphere called Aurora Australis.

The science: The Northern Lights most frequently appear near the Arctic Circle, with activity greatest in places like Lapland. They result from collisions in the upper atmosphere between electrically charged solar particles and gases like oxygen and nitrogen. Pulled toward the North Pole due to the Earth’s magnetic field, it’s this interaction that generates the colourful displays.

In February 2026, NASA launched twin GNEISS (Geophysical Non-Equilibrium Ionospheric System Science) rockets into the Northern Lights from Alaska to create a three-dimensional view, similar to a CT scan, of the Aurora’s electrical currents. According to a post by Miles Hatfield at Goddard Space Flight Centre, these rockets collected strong data about the “electrical circuitry underlying the aurora” for further analysis into how these dazzling light shows are wired.

The magic: Sometimes the Northern Lights start as an oh-so-subtle green glow on the horizon, sometimes you’re almost enveloped by a heavy swell of Aurora dancing all around. Witnessing them is incredibly energising, and even though you’re out in total stillness deep inside the Arctic Circle, it can feel like the sky is buzzing… and some scientists think it is! 

Best time to view: From November to March, between 9pm and 2am.

Midnight Sun

Imagine a period of daytime in the height of summer that lasts for 24 hours… or more! That’s the Midnight Sun, an almost surreal experience where the sun remains up constantly and it never gets dark. You’ll also hear this referred to as ‘polar day’ or ‘nightless night’.

The science: The Midnight Sun is caused by the Earth's axial tilt towards the sun during its orbit. This means the North Pole is angled to the sun, while the South Pole is angled away from it – and that’s why the hemispheres experience opposite seasons! The midnight sun occurs around the June solstice each year. Depending on how far north you travel in Lapland, this perpetual daylight can last from a single day to a few months.

The magic: An endless golden light bathes the Arctic landscape – whether it’s 8am, 3pm, 8pm or 3am. This round-the-clock daylight is both strange and beautiful. It can also be disorienting because time begins to lose meaning… and you begin to lose sleep when you close your curtains in the wee hours at what looks like mid-afternoon. But visitors to Lapland often find they are more energetic and active with the Midnight Sun. Plus, there are late-night activities such as midnight hikes, golf and kayaking to enjoy. 

Best time to view: From late May to late July.

Polar Night

This is a period during winter in Lapland when the sun stays below the horizon, casting a dreamy, blue-tinged glow sometimes mixed with the pastel hues of sunrise or sunset. The Finnish word for polar night is ‘kaamos’.

The science: Although polar night is part of the darkest time of the year in the Arctic Circle, don’t expect it to be pitch black. The sun doesn’t show itself above the horizon, but sunlight still reaches the atmosphere’s upper layers, which allows some ambient light to get through. This creates a brilliant cobalt tone that washes over everything. Often called ‘the blue hour’, it actually can last for several hours in the middle of the day with morning and afternoon blurring together plus a dim glow on the horizon.

The magic: Try to imagine days with no sunrise. The moon and stars provide some illumination, as does the reflection from snow and at night the Northern Lights may add their unique glow, all creating a surreal experience unlike anything else. 

Best time to view: From December to mid-January.

Sun dogs

A sun dog, also called a ‘parhelion’, is a concentrated patch of light that appears on one or both sides of the sun. It’s an optical illusion that makes it look like there are three suns in the sky.

The science: A sun dog shows up beside the sun when sunlight passes through a thin veil of ice crystals in high clouds. The ice acts as a prism, refracting the sunlight. Typically appearing in pairs, sun dogs are seen about 22° to the left or right of the sun. Although they can happen anywhere, chances are higher you’ll see them in Lapland vividly because there are so many tiny ice crystals in the air and the sun sits low on the horizon for long periods in winter. Sun dogs are usually white and red closer to the sun, but they can also be colourful, like bright rainbows.

The magic: Seeing a sun dog involves a mix of disbelief that quickly turns into awe. There have been many legends told involving the sun’s companions. According to Greek mythology, the illusion is simply Zeus walking his dogs across the sky.

In medieval times, seeing the three bright suns was thought to be a sign of great fortune. As dawn broke on 2 February 1461, the three bright suns were famously seen in Herefordshire before the Battle of Mortimer’s Cross. Initially frightening Edward of York’s troops, he convinced them it was a symbol of the Holy Trinity and a divine omen of victory. Shakespeare dramatised this in Henry VI, Part III, Act 2 with these lines:

  Three glorious suns, each one a perfect sun;
  Not separated with the racking clouds,
  But sever’d in a pale clear-shining sky.
  See, see! They join, embrace, and seem to kiss,
  As if they vow’d some league inviolable:
  Now are they but one lamp, one light, one sun.
  In this the heaven figures some event.

Best time to view: From December to March, during the daylight hours when the sun sits low on the horizon.

In Lapland, the skies perform a whole gallery of spectacles… offering shows you won’t find on any other stage. From dancing aurora to everlasting day and night, these are moments that feel unreal. No words or photos can truly capture them – to understand it, you’ll have to step inside the Arctic Circle!
