What is the midnight sun?

Imagine a summer day that never ends, where the sunset is also the sunrise, where people play golf when they should be in bed. Wait, what? Indeed, the midnight sun can be a little distorienting to those who've never experienced such a thing.

You see, here in the Nordic countries, our seasonal shifts are a bit extreme. We'll do our best to explain our wildly varying seasonal daylight hours below.

What causes the midnight sun?

Scientifically speaking, the midnight sun is a natural phenomenon that occurs in far northerly latitudes — particularly at or above the Arctic Circle — during summer, when the earth's axis is tilted more towards the sun. It peaks at the summer solstice, usually around the 21st of June each year.

At its peak, the sun does move position in the sky, but it does not dip completely below the horizon. Depending on how far north you travel, the period of non-stop daylight can last from a single day to nearly five months. In the town of Ilulissat in Greenland, for example, the midnight sun appears from mid-May to late July.

Where can you experience this?

Nordic Visitor destinations that experience this phenomenon include Svalbard, the Lapland region of Scandinavia and northern parts of Iceland and Greenland

In areas below the Arctic Circle, but above 60° north latitude, the sun may dip a few degree below the horizon but not enough for full nightime darkness to set in. These are referred to as white nights. Most of our Nordic destinations experience this to some degree during summer.

How do the daylight hours change?

After the summer solstice, the daylight gradually gets shorter by a few minutes each day, the sunsets get earlier and earlier, until the far north returns once again to winter darkness and northern lights season. To get a better idea of the shifting daylight hours, take a look at our sunrise and sunset table for Iceland.

The opposite phenomenon of the midnight sun is polar night, peaking at the winter solstice in December, something you can experience at 78° north on an adventure in Svalbard.

What to do with all the extra summer daylight?

Here's another helpful tip: if you're a light sleeper, you may wish to pack a sleep mask for summer visits to the Nordic countries. Of course, we won't judge if you want to stay up past your bedtime.

Are you visiting the Nordics in wintertime instead? Lucky you! There's another natural phenomenon you may get to experience — the northern lights.
