The Midnight Sun
Every summer in Norway’s Arctic, a phenomenon occurs where the sun never sets below the horizon, even at midnight. Learn more about the Arctic’s endless sunshine and what causes it.
After a long day, the sun approaches the horizon at around midnight. Still full of energy, you settle down to watch another day’s sunset. The evening light filters across the sea and bathes the deck in an otherworldly glow that you’ve seen many times before. You wait for the sun to dip out of sight, but it doesn’t. Once you’ve realised you’ve crossed the Arctic Circle, the sunset is interrupted by the dawn, and the sun begins to rise again.
What is the Midnight Sun?
Norway is well-known for its long summer days, but above the Arctic Circle, the days aren’t just long – they’re unending. As night falls over the south of the country, in northern Norway the sun lingers, and it can be seen crossing the sky throughout the night.
This natural phenomenon has many names – “Polar Day”, “White Night”, “Nightless Night” – but the most common is the “Midnight Sun”.
Why does the Midnight Sun occur?
As the Earth travels around the sun, we experience different seasons. Because the Earth also rotates on its own axis, we experience day and night. However, the Earth is tilted on its axis by 23.4 degrees, meaning that one hemisphere is always closer to the sun than the other. This is why we have opposite seasons in the northern and southern hemispheres.
During summer in the northern hemisphere, the North Pole is tilted towards the sun. As the Earth turns, the Polar Region stays facing the sun, and the North Pole itself doesn’t experience darkness for six whole months. Arctic areas just south of the pole also experience the Midnight Sun, but for shorter lengths of time. The effect is diluted further south, and instead of the golden nights of the Arctic summer, places south of the Arctic Circle simply see longer days. Areas close to the Equator experience very little change in daylight hours between the seasons.
Once summer is over, the sun sets over the Polar Region for the first time in months. This sunset will send the North Pole into six months of darkness, while other parts of the Arctic will experience both day and night for some months, before entering Polar Night during the winter.
Where can you see the Midnight Sun?
During the summer months, you’ll find the Midnight Sun anywhere north of the Arctic Circle. This is the abstract geographic line that cuts through Sweden, Finland, Russia, Iceland, Alaska, Canada, Greenland, and of course, the Land of the Midnight Sun itself, Norway.
This celestial event lasts longer the further north you go. In the Svalbard archipelago, Norway’s crown of islands in the High Arctic, the sun can be seen for 24 hours a day from late April to late August. This means that the locals enjoy just over four months of constant sunlight in the summer. Most parts of Norway that experience the Midnight Sun do so from mid-May until mid-July.
When can you see the Midnight Sun?
The northern hemisphere's summer solstice is on 21 June, but above the Arctic Circle the endless days last throughout the summer months.
Svalbard: 20 April - 22 August
North Cape: 13 May - 31 July
Hammerfest: 16 May - 28 July
Vardø: 16 May - 28 July
Tromsø: 20 May - 25 July
Harstad: 24 May - 20 July
Svolvær: 28 May - 17 July
Bodø: 3 June - 11 July
What effect does the Midnight Sun have on people?
Like most living things, humans are strongly affected by the light from the sun. You’ve likely heard of circadian rhythms, which describe the various changes our bodies experience throughout the day. These rhythms are regulated by our body’s internal biological clock, which is influenced mainly by our genetics, but also by the light conditions around us. This is why we tend to feel alert during the day when it’s light, and sleepy at night when it’s dark. So what happens when it doesn’t get dark?
Many local Norwegians relish the endless sunlight and the energy boost they get from the Midnight Sun. In the spirit of friluftsliv (the quintessentially Norwegian love of the outdoors), they fill their days with outdoor activities, using the season to deepen their connection to nature. You might find these locals kayaking in the early hours of the morning, or hiking through the mountains late into the night, knowing the sun will always be there to light the way home.
When visiting the land of the Midnight Sun, you might start to lose track of time as one day melts into the next. The days take on a dreamy quality, and even those normally early to bed might find themselves chatting with fellow shipmates in the lounge far past midnight. No longer having to organise their routines around short periods of daylight, locals are able to relax a little, and many will stay up well into the night. In Norway, summer is for socialising, and Norwegians make great use of the bright nights with barbecues and late-night drinks outdoors.
Photography tips
The light from the Midnight Sun is similar to the “golden hour” just after sunrise or just before sunset, when photographers rush out to make use of the perfect natural lighting. Like all shooting conditions, this kind of lighting has its own set of unique challenges, but if overcome or worked around, you can create some stunning shots.
Of course, photography is art, and the Midnight Sun provides the perfect light for surreal and atmospheric shots. So play around with different settings and tools, and have fun seeing what you can create!
1. Take your time, but plan ahead
The great thing about the Midnight Sun is that it stretches out the golden hour to last almost the entire night. This means that you don’t need to rush, but it’s still a good idea to plan ahead, watch the weather, and get an early start. Once the sun looks like it’s setting, it’s time to start shooting.
2. Watch your white balance
If you normally have your white balance set to auto, now is the time to change that. On auto, your camera will balance out the excessive warmth in the photo by adding blue tones. But when shooting under the Midnight Sun, you likely don’t want to balance out the warm tones. If anything, you’ll want to enhance them!
To make the most of the golden hues, use a manual setting, or use one of the presets such as “shade” or “cloudy”. This way, your photos will show the Midnight Sun as it truly is.
3. Use a filter
When taking photos under the Midnight Sun, it can be tricky to get a consistent exposure. The sky is still bright, while the colours of the land and sea are more muted, so either the sea will appear dark, or the sky will be overexposed.
A helpful tool to achieve a more balanced image is a graduated neutral-density filter. This filter is darker at the top and lighter at the bottom, so it evens out the exposure. If your goal is lifelike, vibrant seascapes, it might be worth picking up a filter before your trip. In a pinch, the lens of a pair of gradient sunglasses might also do the trick, but the results may be a little unpredictable.
