Here’s everything you need to know about visiting Iceland in September.

One of the highlights of visiting Iceland in September is the chance to witness the aurora borealis. As the nights grow longer, the dark skies provide an ideal backdrop for the mesmerizing Northern Lights. It’s one of the best times to visit for those hoping to catch this spectacular natural phenomenon.

September also marks the beginning of the fall colors season in Iceland. The landscapes transform into a tapestry of reds, oranges, and yellows, offering breathtaking views and excellent photography opportunities. The changing foliage adds a vibrant touch to the already stunning scenery.

The times to visit in September can vary depending on what you want to experience. Early September tends to be milder, making it ideal for outdoor activities and sightseeing. As the month progresses, the weather becomes cooler, and the chances of seeing the aurora borealis increase. Therefore, whether you prefer milder temperatures or are eager to see the Northern Lights, September in Iceland has something to offer everyone.

With the blend of average temperatures, fall colors, and the allure of the aurora borealis, September is an excellent time to explore Iceland’s unique and diverse environment.

Best rental car for Iceland in September: How to get a cheap car?

Renting a car in Iceland in September is a bit less competitive than other months but you’ll still want to book ahead of time!

When you’re considering which car to choose, think about what you plan to do, how many people will be in your group, and how much luggage you plan to bring.

Additionally, it’s essential to consider road conditions during this time of year. In September, the road conditions in Iceland can be quite varied. While many main roads remain accessible and in good condition, rural and highland roads might start to get slippery due to rain or early snowfall, especially towards the end of the month.

Look into the destinations you’re planning to drive to before choosing your car as you might need a 4×4 vehicle. If you’re coming later in the month when snow might start to fall, renting a 4×4 is a good idea.

Our top tip though? Rent with Firefly Iceland Car Rentals!

Our rental car agency offers some of the cheapest car rental options in Iceland. The least expensive option caps at $35 per day for a small car while a 4×4 is about $45 per day. September is a great month to come to Iceland if you’re trying to avoid high prices too.

What to do in Iceland in September

September is one of the only months of the year in Iceland where you can experience a taste of summer and catch a glimpse of the northern lights! Here are some of the best things to do if you visit Iceland in September.

Whale Watching tour & Puffins: Whales return to Icelandic waters in May and stick around through October. Although it’s technically possible to see whales at any time of year in Iceland, September is one of the best times. Humpback whales and minke whales are the cetaceans you’ll likely see! September is also one of the last months of the year to see puffins, nesting along Iceland’s craggy cliffs.

Attend a Festival: September is a great month to visit Iceland if you’re wanting to attend a festival! Ljosanott, also known as the Night of Lights, celebrates the welcoming in of Iceland’s darker months while the Reykjavik Jazz Festival is in full swing in Iceland’s capital at the beginning of the month. Another noteworthy event is the Reykjavik International Film Festival, which showcases a diverse range of films and attracts cinema enthusiasts from around the globe.

Hiking: As long as the snow holds off, Iceland’s hiking trails should all be open in the month of September, which makes it an excellent time to go on an adventure. With little rain and mild temperatures, visitors will find slightly less muddy conditions and beautiful weather than other times of the year. Consider exploring the nature reserves like Hornstrandir in the Westfjords or Þórsmörk in the Highlands for breathtaking landscapes and wildlife.

Soak in Hot Springs: Temperatures start to turn chilly in September in Iceland, which makes it the perfect time to soak in a natural hot spring! Whether you hike out to a hidden pool or go to one of the popular geothermal watering holes like the Blue Lagoon, there are hundreds of hot spots to take a dip in. Additionally, Iceland’s many swimming pools, heated by geothermal energy, provide a relaxing way to unwind.

Road Trip the Ring Road: One of the best things to do in Iceland is take a road trip around the Ring Road, also known as Route 1. You can easily start in the capital of Reykjavik and circumnavigate the entire country in a perfect circle, seeing some of the most beautiful sites like waterfalls and black sand beaches along the way. Notable stops include the stunning south coast, with its iconic waterfalls like Seljalandsfoss and Skógafoss, and the dramatic landscapes of the Reykjanes Peninsula.

Visit Iceland’s Hidden Gem with a 4×4 Vehicle: It’s still possible to visit Iceland’s remote interior in September. This is one of the most secluded and untouched areas of the country. You’ll need a 4×4 vehicle to drive the roads in this region where you’ll find hiking trails and hot springs. Exploring North Iceland can also be rewarding, with its unique geothermal areas, such as Mývatn, and the impressive Dettifoss waterfall.

Explore the Golden Circle: No trip to Iceland is complete without visiting the Golden Circle, which includes the Þingvellir National Park, the Geysir Geothermal Area, and the Gullfoss waterfall. This popular route offers a fantastic introduction to Iceland’s natural wonders and is easily accessible from Reykjavik.

Tips for Visiting Iceland in September

September is technically still the high season for travel in Iceland. You’ll want to book your hotel, tours, and rental car in advance, preferably at least 3 months. If you’re visiting at the end of the month, competition starts to go down.

Getting around Iceland in September is fairly easy as the heavy snow and ice of winter haven’t started quite yet. Winter weather can creep in towards the end of the month which is something to keep in mind! If you don’t have experience driving in snowy conditions, you might want to rent a 4×4 vehicle and avoid some of the more remote destinations at the end of September.

All restaurants, hotels, and other services will be open in September unless heavy snowfall begins early. You can check Iceland’s weather conditions on their official website.
