Iceland in September 2026: 9 Reasons It's the Best Time to Visit

Planning an Iceland Trip? When's the Best Time to Go?

While summer is famously popular and winter draws crowds for the Northern Lights,

we embarked on a month-long campervan adventure in September.

And we wholeheartedly recommend September for your Iceland journey.

Because in September, you can experience a blend of Iceland's seasons: the lush green of late summer, the vibrant reds of autumn, and even the first dusting of winter snow. We saw the Northern Lights, spotted puffins, and even encountered whales.

Based on our firsthand experience traveling through Iceland in September,

here are 9 compelling reasons why you should consider it.

1. The Northern Lights Season Begins

September marks the start of the Northern Lights viewing season. While many expect to see them later in the month, we witnessed our first aurora display as early as September 7th.

The aurora forecast often shows high activity during this month. The main challenge is typically the weather – clear skies are crucial. In summer, the nights are simply too bright for the aurora, but by September, the darkness returns sufficiently for spectacular shows.

During our trip, we encountered an unexpected night where the aurora filled the sky, a truly unforgettable moment.

2. You Can Still Spot Puffins

Many travelers believe puffins are exclusively a summer sight, but in early September, you can still find them in certain areas. We were lucky enough to spot these adorable birds along the southern coastal cliffs.

With the peak season winding down, there were significantly fewer people, allowing us to observe them in a much more relaxed setting.

3. Whale Watching Season is in Full Swing

September is actually an excellent time for whale watching. In Húsavík and the northern fjords, you have a great chance to encounter humpback whales, minke whales, and even sperm whales.

We personally joined a whale watching tour and had an incredible close-up encounter with these magnificent creatures.

4. Autumn Foliage Graces Iceland's Landscapes

This was genuinely unexpected, but Iceland truly has autumn colors!

Birch forests and moss-covered fields transform into stunning tapestries of yellow and orange. Places like Ásbyrgi Canyon and the northern regions, in particular, take on an entirely different, breathtaking ambiance with the added autumn hues.

5. Tourist Crowds Significantly Thin Out

As August ends, so does the peak summer season.

Parking becomes much more plentiful, and wait times at popular attractions are drastically reduced. This means you can take your time capturing photos and truly soak in the magnificent landscapes without feeling rushed.

During peak season, finding a campsite can be a challenge, but in September, it's generally much easier to secure a spot.

6. The Weather is Perfect for Hiking

The true magic of an Iceland trip often begins the moment you step out of your vehicle. Walking to waterfalls, ascending to glacier viewpoints, and traversing canyons and volcanic landscapes are essential to truly experience Iceland's breathtaking scenery.

In this regard, September offers the ideal weather for hiking. The average temperature in September hovers around the low 40s to low 50s Fahrenheit (approximately 43-52°F). Midday is perfect for a comfortable stroll; it’s not so hot that you'll sweat excessively.

It's a time when you won't be exhausted by intense summer sun, nor will you have to worry about snow and ice like in winter.

7. Hot Springs Become Even More Special

No trip to Iceland is complete without experiencing its incredible hot springs.

However, soaking in the same hot springs in September offers a completely different vibe. The air in Iceland in September becomes quite crisp. The wind is cool, and by evening, you'll likely need to pull out a jacket or even a light puffer.

It's in this cool, refreshing air that you immerse yourself in the warm embrace of a hot spring, and in that moment, you'll understand why an Icelandic journey is so uniquely special.

8. Enjoy Both Long Days and Dark Nights

Icelandic summers have incredibly long daylight hours, while winters see the sun set very early. September, however, strikes a perfect balance, offering the best of both seasons.

In early September, you'll still enjoy nearly 14 hours of daylight, and throughout the rest of the month, there's ample daylight for exploration. You can spend your mornings visiting waterfalls and glaciers, enjoy a hike, and still have plenty of time to relax before welcoming the evening.



9. It's the Most Photogenic Season

The golden hour stretches longer, allowing you to capture cinematic landscapes wherever you point your camera. In September, the sun's angle in Iceland becomes lower.

This results in softer light even at midday, and the golden hours before sunrise and sunset extend beautifully. Waterfalls often display more vivid rainbows, glaciers and lakes shimmer with deep blue hues, and mountains and fjords are bathed in warm, ethereal sunset colors.

Even if you're not a professional photographer, the results you'll achieve in September are exceptional. Whether you're shooting with a drone, a smartphone, or a professional camera, every frame looks like a postcard.
