Iceland in September: The Complete Travel Guide (Weather, Tips & Things to Do)

Iceland in September at a Glance

• One of the best months to visit Iceland
• Mild weather, usually around 45–55°F (7–13°C)
• Fewer crowds and better value than peak summer
• Northern Lights season begins in mid-September
• Open roads make it a great time for a road trip
• A campervan gives you the freedom to explore more

We might be biased, but Iceland really is one of those places that feels worth visiting every month of the year. In early spring, the ice thaws, and everything comes back to life, from roaring waterfalls to green valleys waking up under the last patches of snow. During fall, everything slows down: quieter roads, cooler air, and a color palette that seems to change by the hour. 

Ideally, you’d get to experience the land of fire and ice in every season. But if you’re choosing just one month, Iceland in September is hard to beat. You get a taste of summer and a hint of winter. The days are still long enough to do plenty of activities, but dark enough at night to catch the auroras. Crowds thin out, roads stay open, and campgrounds feel relaxed but not yet completely empty.

Are you convinced going to Iceland in September is the right option for you? Here’s everything you need to know. 

Is September a Good Time to Visit Iceland?

Yes, September is one of the best months to visit Iceland due to fewer crowds, mild weather, and the return of Northern Lights visibility. You still get the freedom of long road trip days, but with cooler air, green-and-gold landscapes, and a stronger chance of spotting the aurora.

Most of the summer experiences are still available, too, like whale watching, glacier hikes, horse riding and even puffin spotting if you’re early enough in the month. This means that you get all the access without the peak-season chaos. 

Visiting Iceland in September: Pros & Cons

September gives you a great middle ground in Iceland. The busiest summer crowds have started to fade, prices can be more reasonable, and conditions are still good for road trips and outdoor adventures. It is also one of the first months when you have a real chance of seeing the Northern Lights again. The main trade-off is that the weather becomes a little more changeable, and daylight starts to shorten as autumn sets in.

Pros of visiting Iceland in September

• Fewer crowds at major attractions compared with June, July, and August
• Lower prices on flights, rental cars, and accommodation than in peak season
• Mild temperatures that are still comfortable for road trips, sightseeing, and outdoor activities
• The Northern Lights start to become visible again from mid-September
• Most popular summer activities are still available, including whale watching, glacier hikes, horse riding, and many road trip routes
• Early autumn colours make the landscapes even more beautiful, with green, gold, and mossy tones across the countryside

Cons of visiting Iceland in September

• The weather can be more unpredictable, with more wind, rain, and colder evenings
• Daylight hours begin to shorten, so you have less time for sightseeing than in midsummer
• Puffin season is nearly over, so sightings are less reliable later in the month
• Highlands routes and more remote areas may start to become less accessible depending on conditions
• Northern Lights are possible, but never guaranteed, and still depend on darkness, cloud cover, and solar activity

Summer vs Winter vs Shoulder Season in Iceland

Iceland is often thought of as a summer or winter destination, but September actually sits right in between, in what’s known as the shoulder season. This is the sweet spot where you get a mix of both worlds: some of the accessibility and milder conditions of summer, with the darker nights and natural phenomena of winter starting to return.

Alongside April, September is one of Iceland’s key shoulder season months — but the experience can feel quite different depending on which side of the year you visit.

September vs April: Shoulder Season Comparison

Weather in Iceland in September

Average temperatures range from 45–55°F (7–13°C), so you’ll want to pack layers but nothing extreme.

You’ll likely get a little of everything: sunshine, chilly breezes, light rain, and in higher elevations, maybe even the season’s first dusting of snow. The weather changes quickly, though, which we consider part of the experience. By mid-September, fall foliage starts to spread across the landscape, and Iceland’s landscapes become picture-perfect with golden grasslands, red moss, and mountain peaks starting to frost.

How Many Hours of Daylight in September?

Daylight starts to shorten in September, but there’s still plenty of time for exploring.

• Early September in Iceland gets around 14 hours of daylight.
• Late September in Iceland sees around 11 hours of daylight.

That means you can still cover a lot of ground during the day and settle in with a cup of cocoa for a front-row seat to the aurora at night. 

Can You See the Northern Lights in September?

Yes, from mid to late September, dark nights return to Iceland, making it possible to see the Northern Lights if skies are clear and solar activity is strong.

While early September still has long daylight hours, by the middle of the month, nights are dark enough for aurora viewing. It is one of the first opportunities after summer to catch the Northern Lights, especially if you are staying outside of major towns and keeping an eye on the forecast.

Tips for seeing the Northern Lights in September

• Check the aurora forecast and cloud cover daily
• Head out between 9 pm and 2 am for the best chances
• Get away from city lights for darker skies
• Be patient — sightings can come and go quickly
• Dress warmly, as nights can feel much colder than daytime temperatures

Best places to see the Northern Lights

• Thingvellir National Park – close to Reykjavík but still very dark
• Snæfellsnes Peninsula – great mix of scenery and low light pollution
• South Coast (e.g., Vík, Skógafoss) – easy access and wide open skies
• North Iceland (e.g., Akureyri area) – often clearer skies and fewer crowds
• Westfjords – remote, quiet, and excellent for dark-sky viewing

For the best experience, consider staying in rural areas or traveling by campervan so you can move to clearer skies when conditions change.

What to Wear in Iceland in September

Packing for Iceland in September is all about layering. The weather can change quickly throughout the day, so wearing multiple layers lets you easily adjust to shifting temperatures, wind, and rain.

The ideal layering system:

• Base layer – A thermal or moisture-wicking layer to keep you warm and dry
• Insulation layer – A fleece or down jacket to retain heat
• Waterproof shell – A windproof and waterproof outer layer to protect against rain and strong gusts

Essential items to pack:

• Waterproof jacket
• Sturdy hiking boots (preferably waterproof)
• Thermal layers (tops and leggings)

You might also want to bring gloves, a hat, and a scarf for colder evenings, especially if you plan to go Northern Lights hunting.

What Are the Best Things to Do in Iceland in September? 

If you decide to travel to Iceland in September, you’re truly in for a treat. The country has something for everyone; you can explore local culture, chase natural wonders, relax in hot springs, or explore under the stars, all with fewer crowds and cooler temps. It’s also one of the best months to travel in a campervan, giving you total freedom to follow the weather, make last-minute detours, and sleep close to whatever you’re seeing.

Here are just a few of the many things to do in Iceland in September.

1. Experience Local Festivals 

Iceland’s September festivals blend rural traditions and urban culture for a truly local experience. The month kicks off with countryside traditions mixed in with city buzz. You’ll find everything from sheep roundups to indie film screenings, all in one trip:

• Réttir: Every September, locals gather across rural Iceland for the annual sheep round-up. It’s one of the most authentic cultural experiences you can catch, complete with horseback riders, community feasts, live music, and a peek into Icelandic farm life.
• Reykjavík International Film Festival (RIFF): Held in late September, RIFF welcomes a curated lineup of international films to Reykjavík, along with talks, special screenings, and events across the city.
• Smaller events, like local music nights and art exhibitions, also pop up in places like Akureyri and Ísafjörður. 

2. Catch the Northern Lights

No trip to Iceland is complete without chasing auroras, and September nights are finally dark enough to catch the Northern Lights. Best of all, temperatures haven’t dropped too low yet, so it’s the ideal time for staying out late with a camera and hot drink.

Here are some tips:

• Stay outside of city centers for better visibility.
• Use aurora forecast apps and check cloud cover maps.
• Campervans give you the freedom to move with the sky and find clear patches on the go. Check out our Northern Lights blog for more info.

3. Soak in Hot Springs

Iceland’s hot springs are especially relaxing in September’s cooler weather and with fewer crowds. Plus, there’s something about warm geothermal water meeting the fall air that hits differently in the fall. 

Some of the best hot springs in Iceland for soaking during September include:

• Blue Lagoon: Still open and still stunning; go at sunset for dramatic light and fewer crowds
• Secret Lagoon: Smaller and more rustic, but just as relaxing
• Sky Lagoon & Forest Lagoon: Stylish alternatives with scenic views and less foot traffic

4. Visit Iconic Waterfalls 

September is one of the best months to visit Iceland’s waterfalls, with full flow and stunning fall scenery. With glacier melt still running strong and fall colors coming in, Iceland’s waterfalls are at their most photogenic this time of year. 

Top waterfalls to visit:

• Gullfoss: A Golden Circle staple with thunderous power
• Skógafoss: Dramatic, accessible, and often framed by rainbows
• Seljalandsfoss: The famous one you can walk behind—bring a rain jacket
• Dynjandi: A remote beauty in the Westfjords if you’re going off-route

5. Take a Whale Watching Tour

September is still prime time for whale watching in Iceland, especially in northern towns like Húsavík. Boats still go out regularly, especially from the north:

• Húsavík: Known as Iceland’s whale capital
• Akureyri & Reykjavík: Solid options with plenty of departures
• Common sightings: Humpbacks, minkes, dolphins, porpoises

Book early, especially toward the end of the month when tours start scaling back.

6. Go Glacier Hiking

Glacier hikes are popular in September thanks to stable conditions and expert-led tours on dramatic ice formations. During September, the weather is still manageable, the ice is stable, and the views are unreal.

Consider going to:

• Sólheimajökull: A beginner-friendly glacier on the South Coast
• Vatnajökull: Europe’s largest glacier, with multiple tour options

Good to know:

• All gear is included, and certified guides lead every hike
• Book ahead—spots go fast, especially on weekends

7. Drive the Golden Circle

September is ideal for driving Iceland’s Golden Circle, with open roads and iconic sites easily accessible. This classic loop is perfect for a campervan trip: short distances, awesome stops, convenient campsites, and great roads. You can hit the main spots in a day or stretch it over two with some well-timed detours.

Key stops:

• Þingvellir National Park: Historic site and tectonic rift valley
• Geysir Geothermal Area: Watch the Strokkur geyser erupt every 10 minutes
• Gullfoss: One of Iceland’s most powerful waterfalls

Optional stops:

• Kerið Crater: A colorful volcanic caldera
• Secret Lagoon or Fontana Spa: For a warm soak along the way

With a campervan, you can take your time, skip the tour groups, and pull over when something grabs your attention—which it will, often.

Your Three-Day Route

Is Iceland Expensive in September?

While Iceland has a reputation for being pricey, September is one of the more affordable times to visit if you plan ahead. It’s still smart to outline your budget carefully, but you’ll find more breathing room compared to the summer rush. 

September sits just after peak season, so:

• Flights and campervan rentals are often cheaper than in July or August.
• Hotels may offer off-season deals, especially in smaller towns.
• Crowds thin out, which can make tours and activities more available.

That said, some costs stay high year-round:

• Gas, groceries, and eating out can still take up a big chunk of your budget.
• Popular tours (like glacier hikes or whale watching) are priced consistently.

If you’re looking to save:

• Cook your own meals; many campervans come with full setups.
• Use campsites instead of hotels or guesthouses.
• Book flights, vans, and big-ticket tours early to lock in better prices.

Trips to Iceland in September don’t have to break the bank; they just take a bit of planning, like renting a campervan that doubles as your hotel, restaurant, and road trip HQ.

Getting Around Iceland in September 

The best way to get around Iceland in September is by campervan. The roads are still largely accessible, the weather is usually manageable for road trips, and popular routes like the Ring Road and Golden Circle are far less hectic than in peak summer. Traveling by campervan gives you the freedom to explore at your own pace, stop whenever the scenery demands it, and stay closer to Iceland’s most unforgettable landscapes. In a country built for road trips, September is one of the best months to do it this way.

Public transport works fine in Reykjavík in September and year-round, but once you leave the city, options are limited. If you’re not renting a vehicle, day tours are available for major sights, but keep in mind that you’ll be on their schedule, not yours.

 
Is September Safe to Drive in Iceland? 

Yes, September is a great time to drive, though it’s always a good idea to stay smart about the weather. With some prep and common sense, September road-tripping in Iceland is safe, jaw-dropping, and seriously fun.

• Check daily road conditions at road.is and keep an eye on forecasts.
• A 4×4 is handy if you’re heading into the Highlands, though not essential for Ring Road trip.
• Be cautious around foggy areas, wet roads, and sheep wandering near the highway.
