When Is the Midnight Sun in Iceland?

The days are long during summertime in Iceland. Although the midnight sun peaks in June, Iceland’s nights are bright as early as May and as late as August. In Iceland, the sun never sets during these months. 

This brightness is due to Iceland's proximity to the Arctic Circle. The Arctic Circle crosses over Iceland, just barely, incorporating Grimsey Island at the country’s northernmost tip.

As the Arctic Circle’s latitude starts at around 66.5°N, and Reykjavik is located at 64.1°N, the sun will still set in Iceland throughout the summer.

However, this will only leave Iceland with a few hours of bright civil twilight in the height of summer until full daylight resumes once more.

“Civil twilight” is a scientific term given for the period of time the sun is only a few degrees below the horizon.

At the height of Iceland’s summer, it doesn’t get completely dark across the island.

Iceland is not the only country to experience this dazzling natural phenomenon.

All countries north of the Arctic Circle and south of the Antarctic Circle will also experience the midnight sun during their summer months.

That includes Greenland, Norway, Sweden, Finland, Russia, and the U.S. state of Alaska.

What Causes the Midnight Sun?

The midnight sun is caused by the tilt of the Earth's axis towards the sun during summer.

This same tilt of the Earth's axis and the Earth revolving around the sun cause seasons to happen.

Each year the Earth’s Northern Hemisphere tilts towards the sun between April and September (and then the Earth’s Southern Hemisphere tilts away from the sun) and vice versa between September and April.

As a result, summer occurs in the Northern Hemisphere in June, July, and August. Summer occurs in the Southern Hemisphere in December, January, and February.

The Earth’s poles get the most contrast, both being exposed to the sun's rays continuously for six months and then experiencing total darkness, or “polar” nights, for the remaining six months.

As a result, both the North Pole and the South Pole have the midnight sun, sporting continuous daylight for six months.

It’s bright at the North Pole and dark at the South Pole from late March to late September, while the other half of the year sees this reverse.

The closer you are to the North or South Pole, the more drastic the change between the summer and winter.

Most of the world’s population lives far enough away from these poles, so the daylight hours and nighttime hours more or less stay the same all year round.

That is not the case in Iceland, where daylight hours are an all or (almost) nothing experience. 

Still, Iceland is far enough away from the North Pole so that the contrast is not as crazy as it could be.

Iceland's day and night hours in March and April (spring) and September and October (fall) resemble what most global standards consider to be “normal,” with the sun rising between 6:00 a.m. - 8:00 a.m. and setting from 6:00 p.m. - 8:00 p.m.

Winter is not completely dark either, although December and January only experience 4-5 hours of daylight each day.

How Do You Sleep During the Midnight Sun?

Naturally, many people find the concept of the midnight sun incomprehensible and can’t imagine how to get any sleep during Iceland’s summer daylight hours. 

The most common question is: “How do you sleep?”

If you must sleep in total darkness, do not despair! Thankfully, there's a clever invention called “curtains” that Icelanders utilize throughout their homes.

You can even use blackout curtains to eradicate any hint of sunlight (preferable for vampires or those with sun allergies). 

Another common question is: “Isn’t it weird for it to be bright all night long?”

Well, the short answer to that is yes; after experiencing such a dark winter, the endless days of daylight hours in Iceland do make a striking difference.

The long days become part of your daily life, feeding your energy with 24/7 light. 

It’s great for sightseeing too! No more worrying about time restraints, needing to get somewhere, or getting home or getting to bed "before it gets dark."

With endless days come endless possibilities for activities, events, get-togethers, and exploration.

What’s There To Do During the Midnight Sun in Iceland?

Some tours take advantage of these late nights. Many midnight sun tours are available to you, like the Golden Circle, whale watching, or mountain hiking.

Taking a midnight sun tour allows you to experience some of Iceland's best attractions in a truly unique way, thus maximizing your time on the island.

If you rent a car and travel late at night, fewer people will be around, so you can see destinations in stunning twilight colors and be entirely on your own.

This solitude is just one reason why traveling beneath the midnight sun is often sought after.

It’s possible to travel everywhere in Iceland during the summer, whereas some areas are not accessible during the winter months.

The Icelandic Highlands is one example of a region only accessible from late June or early July until September.

Due to heavy snow and bad weather, it may be difficult to access the Westfjords and even some parts of North and East Iceland at the height of winter. 

This type of inconvenience is not a problem during the summertime. Although it may sometimes be windy, rainy, or foggy, it’s doubtful that there will be any snowstorms hindering your travel plans around the country.

We recommend renting a car and exploring the country at your own pace.

There's a variety of summer self-drive tours available, where it's up to you to choose if you want to visit some of Iceland's attractions at noon or midnight.

There are also a plethora of exciting tours available during this more agreeable part of the year, such as:

With the long days, you can fit in more hours of sightseeing, driving around, and doing activities to max out your holiday time in Iceland.

If you’re looking for other festivities or events that happen during the time of the midnight sun, you’re in luck. The Midnight Sun Run occurs yearly in June in the Laugardalur valley. 

The Secret Solstice Festival is another event that happens in the summer. This unique music and cultural festival include special events like a rave in a glacier cave!

For those visitors that rather stick to themselves, enjoying the natural beauty of Iceland during the midnight sun is much easier. Head to one of the many thermal swimming pools or hot springs to take a dip at any time of day. 

Summer and Winter Solstices in Iceland

The further north or south you go on the planet, the more daylight is affected by summer and winter solstices.

Iceland’s longest day of the year (the summer solstice) is around June 21.

On that day in Reykjavik, the sun sets just after midnight and rises again right before 3 a.m., with the sky never going completely dark.

The further north you go in the country - such as to Akureyri or Isafjorour - the longer you'll find the days.

The effect makes experiencing time in Iceland a unique concept, unlike anywhere else. 

The year’s shortest day (the winter solstice) is around December 21.

In Reykjavik, the sunrise is around 11:30 a.m., and the sunset is around 3:30 p.m.

Again, the further north you go in the country, the shorter the day.

Between the shortest and longest days of the year, the days grow or shorten by a few seconds up to several minutes per day.

An equinox occurs twice a year, around March 21 and September, when there’s roughly an equal amount of daylight and darkness.

If you want to know how much daylight there's in a particular month, note that there can be a drastic difference from the beginning and end of that time. Icelands’ sunlight hours will also depend on which location you plan to visit.

You can’t see the sun for around two months in the town of Isafjorour in the Westfjords of Iceland.

Tall mountains surround the town, and it's situated so far north in the country that the sun doesn't rise high enough for its beams to reach over the mountaintops in wintertime.

It’s a well-known tradition that the people in Isafjorour celebrate the first day they see the sun after two months of darkness by baking pancakes and having “sun coffee.”

The absence of sunlight is not nearly as drastic in Reykjavik, which is not surrounded by mountains and is in the country’s south.

Iceland Daylight Hours by Month

Iceland’s hours of daylight vary throughout the year. You may wonder if Iceland is dark for six months or if Iceland has no night in the summer. Reykjavik’s daylight hours are similar to those across the country. If you’re wondering when you can catch the midnight sun or a chance at the equally impressive northern lights, we’ve broken down the daylight hours month by month in Iceland.

Iceland Daylight Hours January

January is the coldest month of the year, and there are limited daylight hours. The average time of Icelands’ sun hours in January is from approximately 11:30 a.m. until 3:45 p.m. - a mere four hours. 

Iceland Daylight Hours February

More sunlight hours make an appearance in February. By the end of the month, the sun is up from 10 a.m. until approximately 5 p.m. 

Iceland Daylight Hours March

By March, the day and night hours begin to even out and create a more “normal” light pattern with 11 hours of daylight. The sun rises at 8:30 a.m. until sunset around 6:45 p.m.

Iceland Daylight Hours April

The table begins to tip towards the midnight sun in April. Fifteen hours of daylight can be expected from 6:45 a.m. until 8:30 p.m. 

Iceland Daylight Hours May

Daylight hours only increase in favor of the midnight sun from here on. Beginning at 5 a.m. until 10 p.m., visitors can admire the attractions of Iceland in the light. 

Iceland Daylight Hours June

Enjoy the summer solstice in Iceland during June. On average, 20-22 hours of daylight can be experienced in June, and the darkness only lasts from 11:30 p.m. until 3:30 a.m.

Iceland Daylight Hours July

To fully experience the midnight sun, a visit to Iceland in July must be in the cards. The sun barely sets during this time. From 3 a.m. until midnight, the sun shines. 

Iceland Daylight Hours August

By August, the sun mimics what happens in April, reducing daylight hours to merely 15 hours per day. Beginning at 4:30 a.m. until 10:30 p.m. 

Iceland Daylight Hours September

Come September, the day and night are about equal by the end of the month at 12 hours apiece. Sunrise occurs around 6 a.m., with sunset at 8 p.m. in the early part of the month and closer to 6 p.m. by the end of the month. 

Iceland Daylight Hours October

October and September have similar daylight hours though October is slightly less. The sun comes up at 7 a.m. and descends at 7 p.m. 

Iceland Daylight Hours November

The dark nights begin to set in by November, with Iceland's winter sunlight hours rapidly decreasing. From 9 a.m. until 5 p.m., the sun is high, and chances of seeing the northern lights also increase at this time. 

Iceland Daylight Hours December

December brings some of the shortest days of the year. The sun appears only from 10:45 a.m. until 4 p.m., just over five hours of daylight.

What About the Time in Between Sunset and Sunrise?

Technically speaking, the midnight sun only occurs in Reykjavik between June 16-29 since these are the only days of the year when the sun sets after midnight.

But if you consider that the sunrise will only be a couple of hours later, you’ll realize that even though the sun isn’t up, it's still bright. Indeed, it only dips marginally below the horizon during the civil twilight hours.

The bright nights last for around three months (one-and-a-half months before and after June 21).

So, while the height of Iceland’s midnight sun is in the last two weeks of June, you'll also get to experience it if you visit Iceland in May, early June, July, or early August.

The slow sunsets and sunrises make for incredibly picturesque displays of colorful twilight skies that last for hours.

A couple of hours per night can get quite dark at the beginning of August, though not more than dusk.

Towards the end of August or the beginning of September, there will be a couple of hours of the pitch-black night, so the northern lights will start appearing in the sky.

Late August or early September is the perfect time of year to experience the long days and milder weather, but still with a few hours of darkness during the night to catch some auroras dancing in the sky.

If you’re looking for a place to visit during the summertime where you can get more hours out of the day (without impacting the crazy nightlife), Iceland is the place to go.
