Weather in September in Iceland

In this guide, we share what you can expect from the weather in Iceland in September. And we’ll suggest some things to get up to in any weather.

What to expect from the weather in September in Iceland

In September, summer turns to fall, and the nights draw in. While the temperatures are lower than in July and August, there’s still plenty to inspire you. The leaves on the trees slowly turn to gold and the landscape is draped in autumnal color.

Here’s what you can expect from Iceland’s September weather in detail.

What are the daylight hours in Iceland in September?

In September, the long, bright evenings of the summer are over and the nights are closing in. You’ve missed the season of the midnight sun, but by September it’s now possible to see the northern lights.

In Reykjavík, on September 1, the sun rises at 06:11 and will set at 20:41, giving you 14.5 hours of daylight. But throughout the month, the days are getting shorter fast. By September 30, the sun doesn’t rise until 07:35, and it sets at 18:58. In comparison, that gives you fewer than 11.5 hours of daylight.

In Akureyri, in the north of the country, the sun rises at 05:50 on September 1 and sets at 20:31. By September 30, it rises at 07:21 and sets at 18:41.

So, by the end of the month, the conditions may be there for you to glimpse the northern lights. However, you’ll usually need to wait until the middle of the night.

What’s the temperature in Iceland in September?

In September, we’ve passed the warmest period of the year and winter is slowly approaching. You can still expect warm days, but it’s best to bring a warm jacket for the evenings.

For instance, in Reykjavík in September, the daily average temperature is 8.5°C (47.3°F), down from 11°C (51.8°F) in August. Average highs are 11.4°C (52.5°F) and average lows are 6.2°C (43.2°F).

Of course, averages are just that. Record September temperatures have reached over 20°C (68°F) and as low as –4.4°C (24.1°F). So, there’s quite a range!

If you’re heading north, you can expect more extreme temperatures. In Akureyri, average temperatures are 8°C (46.4°F), with average highs of 11.8°C (53.2°F) and average lows of 5.4°C (41.7°F). But Akureyri has reached highs of 23.6°C (74.5°F) in September, meaning there’s still some summer warmth around.

How much rain does Iceland get in September?

While Iceland isn’t as dry in September as it is in June, it’s still far from the wetter months ahead. Just make sure you pack a waterproof jacket, as you’ll probably need it, no matter what you have planned.

Iceland’s capital, Reykjavík, is one of the wetter places in Iceland in September. On average, the city gets 87mm (3.43 inches) of rain throughout the month. That’s spread over an average of 15 so-called “precipitation days”, i.e. days on which it rains more than a millimetre.

The north coast tends to be drier. Akureyri, for instance, sees 53.2mm (2.09 in) of rain across September. This falls on 9.4 precipitation days.

So, you have a better chance of staying dry if you head north. But you’ll find there’s lots to do in Iceland no matter the weather.

What to do in Iceland in September (no matter the weather)

Whether the weather’s fine or wet, mild or autumnal, there’s always something to do in Iceland in September. Read on to discover four ideas for activities to enjoy in this season.

1. Venture into the outdoors

Iceland’s outdoors is one of the biggest draws for visitors to the Land of Fire and Ice. And there’s truly no moment when it’s more beautiful than in September.

That’s because of the colours. Head to Iceland’s national parks and forests in September and you’ll see them turning a miraculous variety of autumnal shades of gold, orange, red, and more. Plus, the tops of the mountains will be dusted with snow.

Some of the best places to see this autumnal landscape are Þingvellir National Park or the nature reserve known as Skaftafell. Offering lakes, waterfalls, mountain views, and miles of hiking trails, they’re ideal destinations to explore. Yet there are many more places to see Iceland’s autumn colours, including Heiðmörk (near Reykjavík), Hallormsstaður (in East Iceland), and Vaglaskógur (just outside Akureyri).

In Iceland, September is one of the last months when you can reliably visit the region known as the highlands. In winter, this uninhabited region is cut off by heavy snow. September is your last chance to visit—so it’s worth taking the opportunity!

Note: if you’re planning to visit the highlands in September, check to see if the roads are open first. You can do that on the road.is.

2. Head to one of September’s festivals and events

Iceland has a busy cultural calendar throughout the year, and September is no exception. If you visit this month, you can take part in traditional events and attend festivals across the country.

One of the most unusual events in Iceland is réttir. In September, farmers need to round up their sheep, which are typically out roaming in the highlands, mountains, national parks, and elsewhere across the country. During réttir, you are invited to help them. It’s an authentic way to experience Iceland’s breathtaking landscapes.

Alternatively, September is the month of the Reykjavík International Film Festival, a celebration of movies from across the world. It takes place over 11 days in the capital, usually at the end of the month.

Another option, if you’re into experimental music, is the Extreme Chill festival. It’s been bringing big names in international music to Reykjavík for over 10 years.

3. Sample Iceland’s autumn flavours

After the warmth of the summer, September is one of the best times of year to eat in Iceland. From the beginning of August, locally produced vegetables hit the shelves, while September itself is the perfect foraging and fruit-picking season.

Head out into the heaths and mountains, and you can join in the foraging yourself. September is an ideal time to find blueberries, crowberries, and redcurrants—all of which you can add to your traditional bowl of skyr (an Icelandic yoghurt).

Of course, September still offers fresh seafood and local meat—just as at any other time of year.

To try the best of September’s flavors, visit a restaurant specializing in locally produced, and lovingly prepared food. For instance, at Berjaya, we use the freshest ingredients in all of our dishes, to give you a taste of true Iceland.

4. Relax in an Icelandic spa or hot spring

No matter what the weather is doing outside, an Icelandic spa is a wonderful place to be. They come in all shapes and sizes, so there’s truly something for everyone.

If the weather is good, you have many outdoor spas to choose from. For instance, head to the world-famous Blue Lagoon, for its therapeutic, geothermal waters. Or try Sky Lagoon, with its infinity pool that overlooks the North Atlantic Ocean.

For more of an adventure, try a natural hot spring. One thrilling destination is Reykjadalur, the so-called “steam valley”. Or visit the more refined Hvammsvík spa in Hvalfjörður.

If you want something a little more homely, book a hotel with an onsite spa. At Berjaya, our hotels across Iceland have world-class spa facilities, so you can unwind at the time that suits you.

How to enjoy Iceland in September weather

In September, the weather is changeable and unstable. To ensure you have the best trip possible, bear the following advice in mind:

• Check the forecast wherever you go. Every day can bring something new, so it’s important to stay clued up on the forecast—particularly if you’re heading outdoors. The most reliable source for your weather data is the Icelandic Met Office.
  
  
• Pack for all conditions. While it can be warm in the day, it’s usually pretty chilly come evening. It’s wise to dress in layers, so you can take anything off (or put it back on) depending on what the weather’s doing.
  
  
• Keep an eye out for optimal northern light conditions. You’ll have a better chance to see the northern lights later in the season, but you can still see the incredible display in September. A useful resource is Aurora Forecast, which will share all the information you need.
  
  
• If you’re travelling, check the road conditions in advance. Iceland is a great place for a road trip. But to stay safe and comfortable when driving, check for road closures in advance. The best place to do that is the is.
