Weather in Iceland in September: A Transition Season
September in Iceland is a month of change. The long daylight hours of summer are beginning to shorten, and the landscape is starting to take on the warm hues of autumn. But what about the weather? Here’s what you can expect:
Average Temperatures and Conditions
During September, average temperatures in Iceland range from 6 to 11°C (42 to 59°F). While that might sound relatively mild, it’s important to remember that these are averages. You should be prepared for temperatures to dip below freezing, particularly at night and if you’re venturing into the Highlands.
The weather in Iceland has become less predictable as the earth warms. In September 2024, for instance, many areas saw temperatures that were lower than average, reminding everyone of the possibility of early cold snaps.
September is also considered a rainy month, with an average of 20 days of precipitation. Keep in mind that rainfall can vary quite a bit across the island. Some areas might experience heavy downpours, while others remain relatively dry.
It’s also worth noting that strong winds are common in Iceland, and these can make the temperature feel significantly colder than it actually is. Windproof outerwear is essential for staying comfortable.
Understanding Iceland’s Climate
Icelandic weather is notoriously unpredictable, and September is no exception. Be prepared for sudden changes in conditions, even within a single day. It’s a good idea to check weather forecasts regularly, using reliable resources like Vedur.is, and to be aware of any travel advisories that might be in effect.
September marks the transition from summer to fall, with noticeable changes in daylight hours and the appearance of autumn foliage. The fall colors begin to emerge in various locations, such as Thingvellir National Park and the Highlands, creating stunning landscapes for photographers and nature enthusiasts.
Daylight and the Northern Lights
The amount of daylight you’ll see in Iceland during September depends on when you go. At the beginning of the month, you can expect around 14.5 hours of daylight. By the end, that drops to about 11.5 hours. This means that the average daylight for the month is about 12.5 hours.
The reduced daylight hours are good news if you’re hoping to see the Northern Lights. September is considered one of the best months to view them.
To maximize your chances, get away from the city and find a dark spot. You’ll also need a clear night with as few clouds as possible.
If you really want to see the aurora borealis, consider booking a guided Northern Lights tour. The tour guides are good at spotting the best viewing locations and will monitor weather conditions and aurora forecasts.
Activities and Attractions in September: Balancing Summer and Winter
September in Iceland is a sweet spot. You’re still able to do many of the summer activities, but you may also get a taste of the winter attractions that Iceland is known for.
Popular Activities
- Hiking: Most trails are still open in September, although the Highlands may start seeing some closures due to weather. Before you head out, register your hiking plans with SafeTravel.is and keep a close watch on the weather. Some nice options include the Reykjadalur Valley or parts of the Laugavegur Trail, if conditions allow.
- Whale watching: You can still take whale watching tours in September, especially out of towns like Husavik. This time of year can be great for spotting different kinds of whales.
- Hot springs: Soaking in Iceland’s geothermal hot springs is a great way to unwind, no matter what the weather’s like. The Blue Lagoon and Secret Lagoon are popular, but you can also find more secluded natural hot springs all over the country.
Exploring Iceland’s Regions
- The Golden Circle: This classic route is still a great option in September, with its famous sights like the Gullfoss waterfall, the Geysir geothermal area, and Thingvellir National Park.
- The South Coast: With its black sand beaches, waterfalls, and glacier lagoons, the South Coast is beautiful and easily accessible in September. Don’t miss the Jokulsarlon Glacier Lagoon, where you can see icebergs and maybe even some seals.
- The Snaefellsnes Peninsula: Often called “Iceland in Miniature,” this peninsula packs a lot of different landscapes and attractions into one area.
- The Westfjords: If you’re looking for remote beauty and unique hiking, the Westfjords are a good choice, but be ready for potentially tricky driving conditions.
Basically, September gives you a chance to experience a little bit of everything that Iceland has to offer, from summer hikes to the beginnings of the winter landscapes.
Driving in Iceland in September: What to know
The good news is that Iceland’s famous Ring Road (Route 1) is usually open in September, so you can drive around the whole island. However, it’s always smart to check road.is for current conditions, since weather can close roads in more remote areas.
If you want to explore the Highlands or other off-the-beaten-path areas, I highly recommend renting an AWD or 4×4 vehicle. A 4×4 is almost a must for the Highlands, and you should be aware that you might encounter river crossings. Be careful!
No matter where you’re driving, pay attention to the road. Gravel roads can be tricky, and visibility can change quickly. Iceland’s weather is famous for being unpredictable, so be ready to adjust your driving based on the conditions. Remember that distances can be deceiving, so give yourself plenty of time to get where you’re going. It’s better to arrive late than to have an accident.
Cultural Events and Festivals in September
September is a great time to visit Iceland to experience its culture. You may be able to attend:
- The Reykjavik International Film Festival (RIFF): This festival screens movies from all over the world.
- The Reykjavik Jazz Festival: The jazz festival features Icelandic and international performers.
- Ljosanott (Night of Lights Festival): The town of Reykjanesbær celebrates with light displays, music, and other performances.
- Réttir (sheep and horse round-ups): Farmers bring their livestock down from the highlands in a tradition called Réttir.
- Berjamó (berry picking): Berry picking is also a popular activity in September.
These cultural events and festivals offer a glimpse into Icelandic traditions and contemporary arts.
What to pack for Iceland in September
Packing for a trip to Iceland in September can be tricky. The weather can change quickly. The best strategy is to bring clothes you can layer. That way, you can add or remove layers as the temperature shifts.
Here are some must-haves:
- Thermal underwear: This will keep you warm, even when it’s damp.
- Fleece jacket: Fleece is a great mid-layer because it’s warm and quick-drying.
- Waterproof and windproof outer layer: A good quality waterproof jacket is essential for protecting you from rain and wind.
- Waterproof footwear: If you plan on hiking or exploring, bring sturdy hiking boots with ankle support.
- Warm accessories: Don’t forget a hat, gloves, and scarf.
- Swimwear: You’ll want to take a dip in Iceland’s famous hot springs!
