Is September a Good Time to Visit Iceland?

Yes, September is one of the best times to visit Iceland. It offers a perfect balance between the busy summer season and the colder winter months. 

The long days of summer are ending, but there is still plenty of daylight for sightseeing. At the same time, the darker nights bring back the chance to see the Northern Lights.

You will also enjoy fewer crowds, more comfortable prices, and easier access to many of Iceland’s most popular attractions.

The Pros:

  • The Northern Lights: You finally have enough darkness to see the lights without the extreme cold of January.
  • Fewer Crowds: You won’t have the same “queue for a photo” experience at waterfalls like Seljalandsfoss.
  • Accessible Highlands: Early September is often your last chance to see the interior (Landmannalaugar) before the snow arrives.
  • Wildlife: While puffins leave in late August, whale watching remains world class.

The Cons:

  • The Wind: September is notoriously windy. Gale force winds can occasionally impact driving plans.
  • Variable Rain: You will get wet. It’s not a question of if, but when.
  • Closing Services: Some campsites and smaller museums in remote areas may begin to close for the season.

A Guide to Iceland Weather in September

September is the beginning of autumn in Iceland. While temperatures remain fairly mild, weather conditions become much more unpredictable than during summer.

You may experience sunshine, rain, fog, and strong wind all on the same day.

The key to enjoying Iceland is accepting that changing weather is part of the adventure.

Average Temperature in Iceland in September

The average daytime temperature ranges between 45°F and 50°F (7–10°C).

At night, temperatures often drop to around 41°F (5°C).

Cold spells can occasionally bring temperatures close to freezing in higher elevations, especially toward the end of the month.

Although September is cool, it rarely feels unbearably cold if you wear proper layers.

Rainfall in Iceland in September

Rain is common throughout September.

Most showers pass quickly, but steady rain can also occur, especially along the South Coast and in the Westfjords.

Instead of hoping for dry weather, prepare for wet conditions by packing waterproof clothing.

A quality waterproof jacket and rain pants will make your trip much more enjoyable.

Wind in Iceland in September

Wind is one of Iceland’s defining weather features.

In September, powerful autumn storms occasionally move across the island, bringing strong gusts that can affect driving conditions.

Large vehicles such as camper vans are especially vulnerable.

Always check weather forecasts before driving long distances, and avoid opening car doors without holding them firmly.

Daylight Hours in Iceland in September

One of September’s biggest advantages is the balance between daylight and darkness.

You still have enough daylight for long sightseeing days while gaining dark evenings for Northern Lights viewing.

Early September

  • Sunrise: Around 6:15 AM
  • Sunset: Around 8:30 PM
  • Approximately 14 hours of daylight

Late September

  • Sunrise: Around 7:30 AM
  • Sunset: Around 7:00 PM
  • Approximately 11½ hours of daylight

As the month progresses, sunset arrives earlier each day, making it easier to plan evening aurora hunts.

Can You See the Northern Lights in Iceland in September?

Yes. September is the start of the Northern Lights season in Iceland. 

Once nights become dark enough, the aurora can appear whenever solar activity is strong and skies remain clear.

Unlike winter, September offers a more comfortable experience because temperatures are milder.

For the best chance of seeing them: 

  • Leave city lights behind.
  • Watch the weather forecast for clear skies.
  • Check aurora forecasts before heading out.
  • Be patient, as sightings are never guaranteed.

Many travelers stay in countryside guesthouses where they can step outside if the lights suddenly appear.

What to Wear in Iceland in September

Packing the right clothing is one of the most important parts of planning your trip.

The weather changes quickly, so dressing in layers allows you to stay comfortable throughout the day.

In Iceland, locals often say: “There is no such thing as bad weather, only bad clothing.”

The Three Layer System

The secret is the Three Layer System:

Base Layer

Start with moisture wicking thermal clothing made from merino wool or synthetic materials. 

Avoid cotton because it traps moisture and dries very slowly.

Mid Layer

Add insulation with a fleece jacket or lightweight down jacket. 

This layer helps keep your body warm during windy or cool conditions.

Outer Layer

Finish with a waterproof and windproof shell. 

This is the most important layer since you’ll likely encounter rain, mist from waterfalls, and strong winds. The best option is a men’s and women’s waterproof shell jacket.

A waterproof jacket alone isn’t enough. Waterproof pants are just as useful, especially when visiting places like Seljalandsfoss. 

For more packing ideas, check out our summer clothes guide for Iceland or explore our summer travel packages.

Footwear

Choose waterproof hiking boots with good ankle support.

Many trails become muddy after rainfall, and wet feet quickly make outdoor adventures uncomfortable.

Pair your boots with wool socks to keep your feet warm throughout the day.

Rent Instead of Packing Everything

If you do not want to buy expensive waterproof clothing or hiking boots just for one trip, renting from IcelandCover is an easy way to get the right gear without overpacking. 

You can grab a Comfort Clothing Set Kit and just pick it up when you arrive. It saves you hundreds of dollars and a lot of suitcase space!

Driving in Iceland in September / Road Conditions

September is one of the easiest months for a self drive holiday. Most travelers can comfortably drive the Ring Road using a standard rental car.

Road conditions are generally excellent, and snow is uncommon at lower elevations. However, Icelandic weather can change rapidly, so flexibility is important.

Before leaving each morning, check both weather forecasts and road conditions. Wind, heavy rain, or temporary road closures may require changes to your plans.

Driving on F-Roads

If your itinerary includes Iceland’s Highlands, you’ll likely encounter F-roads. These mountain roads are rough gravel tracks that often include river crossings.

A four wheel drive vehicle is legally required. Many F-roads remain open during early September, but closures begin as autumn weather arrives.

Always confirm road status before entering the Highlands. Never attempt to cross flooded rivers unless your vehicle is designed for it.

Best Things to Do in Iceland in September

September is a fantastic time to explore Iceland. The summer crowds fade, and the autumn colors begin to glow. 

Here are some of the best things to do during your trip.

1. Explore the Snæfellsnes Peninsula

The Snæfellsnes Peninsula is about two hours from Reykjavik. It is often called “Iceland in Miniature” because you can see many of Iceland’s famous landscapes in one place. 

There are glaciers, volcanoes, lava fields, black sand beaches, and small fishing villages. You can visit on a day trip, but staying one or two nights gives you more time to enjoy the area.

2. Hraunfossar Waterfall

Hraunfossar is one of Iceland’s most unique waterfalls. Instead of one large waterfall, many small streams flow through lava rocks into a bright blue river.

In September, the trees and bushes around the waterfall turn beautiful shades of yellow and orange. A short walk away is another waterfall called Barnafoss, which is also worth visiting.

3. Snowmobiling and Ice Tunnels on Langjökull Glacier

If you enjoy adventure, try snowmobiling on Langjökull Glacier. September brings the first signs of winter, making the glacier even more beautiful.

You can also visit the Into the Glacier ice tunnel, a man made tunnel inside the glacier. Snowmobile and ice tunnel tours are available separately or as a combined tour.

4. See the Northern Lights

September marks the beginning of the Northern Lights season. As the nights become darker, you have a chance to see the colorful lights dancing across the sky.

For the best view, travel away from city lights and choose a clear night. You can join a guided tour or stay in the countryside for a better chance of seeing the aurora.

5. Explore the Westfjords

The Westfjords are one of the most peaceful and scenic regions in Iceland. September is a great time to visit before winter snow closes some mountain roads.

Don’t miss Dynjandi Waterfall, Rauðasandur Beach, and the small town of Ísafjörður. The peaceful scenery makes this area perfect for nature lovers.

6. Relax in a Geothermal Hot Spring

After a day of sightseeing, relax in one of Iceland’s famous Hot springs.

The Blue Lagoon is the most popular, while Sky Lagoon offers beautiful ocean views. You can also visit local public swimming pools, where many Icelanders go to relax.

7. Ride an Icelandic Horse 

Icelandic horses are friendly, strong, and easy to ride. They are also known for their smooth and comfortable gait called the tölt.

Horse riding tours are available across the country. Riding through lava fields, green valleys, or along black sand beaches is a fun way to experience Iceland’s nature.

8. Local Festivals and Events

September is a great month to experience Icelandic culture. Reykjavík and other towns host several festivals and community events.

Some popular events include:

  • International Film Festival: This event runs from late September into early October.
  • Night of Lights: A family festival with music, art, and fireworks in Reykjanesbær. 
  • Reykjavik Jazz Festival: This festival features local and international talent in unique venues.
  • Extreme Chill Festival: A great choice for fans of electronic music and visual arts.
  • Réttir Sheep Round Up: A traditional event where farmers gather sheep from the mountains. Visitors can enjoy local food, music, and Icelandic culture. 

These events are a great way to experience local traditions while visiting Iceland in September.
