What to Wear to Iceland in September: Outfit Ideas
1. Thermal Leggings + Oversized Sweater + Waterproof Jacket + Ankle Boots
This is a classic Reykjavik look! It’s all about staying warm and dry, and when you’re strolling the city, you also want to be fashionable. Start with a pair of thermal leggings for that warmth. Add an oversized sweater– fabric like wool is a good choice– and layer an extra waterproof jacket over it. Ankle boots are warm and stylish too! Keep those feet dry.
2. Thermal Base Layer + Hiking Pants + Fleece Jacket + Rain Shell + Hiking Boots
Sightseeing is always required in Iceland, but what happens when you factor in unpredictable weather? For places like the Golden Circle, start with a thermal base layer for warmth. Put on hiking pants over these: the more pockets, the better. Add a fleece jacket and rain shell as needed. But don’t forget those hiking boots: comfort on the feet is needed when exploring.
3. Swimsuit + Quick Dry Towel + Slip on Shoes + Hoodie
Natural hot springs are a must, so add them to your bucket list for Iceland! When you’re exploring places like the Blue Lagoon, choose a comfortable one-piece suit. And bring slip-on shoes for when you’re navigating changing rooms and bathrooms for ease. A quick dry towel will keep you towel off quickly, hence the name, and then throw on a hoodie after to stay cozy!
4. Fleece Leggings + Thermal Top + Puffer Jacket + Trainers
If you’re taking a long drive across the country to go sightseeing, you want to be comfortable. But you also want to ensure you’re ready for any spontaneous photo stops, too! Thermal or fleece leggings are warm and flexible, as is a thermal top. Pair with a puffer jacket as needed and comfortable sneakers: you never know what the terrain will be like when you step out of the car during a road trip.
5. Waterproof Pants + Fleece Pullover + Shell Jacket + Hiking Boots
Geysers and waterfalls are fantastic to explore. But this means water! And mist! Stay dry and warm. Start with waterproof pants and a shell jacket. Underneath you can have a fleece pullover to keep you warm, but in order you stay warm, you need to stay dry. And don’t forget those ever-important hiking boots again!
6. Black Jeans + Wool Sweater + Chelsea Boots + Hat + Scarf
When you’re in the city, you want to show off a more fashionable side of things! This stylish yet warm outfit is perfect as a casual Reykjavik look. It’s perfect for dining or cafe-hopping, or even exploring museums. Black jeans and a wool sweater are your starting point. Add Chelsea boots and a hat and scarf (matching, of course), to add that extra warmth. Take them off as needed, too!
7. Thermal Base Layer + Insulated Vest + Down Coat + Wool Beanie
Whether you’re on a Northern Lights hunt or exploring some cool lava caves, know one thing: it’s cold. So stay warm! Begin with thermal base layers for that extra layer, and their flexibility. Pair with insulated vests and down coats, or even fleece jackets. Just don’t forget those wool beanies! If your head is cold, the rest of you will be!
8. Jeans + Warm Sweater + Puffer Vest + Chunky Sneakers + Crossbody Bag
When stopping at the fjords or participating in scenic drives, be casual but warm enough, especially as you continue to stop and face the wind. Start with jeans. If you know you’re naturally cold, layer leggings under them. Pair with a warm sweater and puff vest, and top it all off with some cute and warm chunky sneakers.
9. Thermal Base Layers + Waterproof Hiking Pants + Fleece + Insulated Jacket + Sturdy Boots
Longer hikes in fall call for more prepared outfits. If you’re trekking through and by Glymur Waterfall or Landmannalaugar, you need to be well equipped with layers and flexibility. Start with base layers! Thermal is best. Then add waterproof hiking pants and a fleece. An insulated jacket is good for those high altitudes and misty areas, but can be taken off as needed. And as always, sturdy boots tie together the ultimate hiking look.
10. Joggers + Fleece Pull Over + Wool Socks + Trainers
You’re on vacation! Sometimes you need a nice, comfy morning, a relaxed morning, before an adventure. So as you go for a chilly morning coffee run, throw on a pair of joggers, a fleece pullover, and then layer up your feet with wool socks and trainers. Perfect for travel days, relaxing in Airbnbs, or visiting cafes.
Weather Guide: September in Iceland
Let’s talk temps. In September, Iceland is officially in fall mode. The temperatures hover around 6–11°C (43–52°F), but thanks to the wind and rain, it feels colder. September also has around 12–14 hours of daylight, which is still plenty of time for exploring. Expect a mix of sunshine, misty rain, and those famous Icelandic winds. It’s unpredictable, so layering for Iceland in fall is an absolute must.
If It’s Rainy: When rain is in the forecast (the reality more days than not), a waterproof shell jacket or parka is your best friend. Layer it over a cozy, wool sweater and pair it with waterproof pants and fleece-lined leggings. Waterproof hiking boots or ankle boots will keep your feet dry as you explore the muddy landscapes.
If It’s Windy or Extra Chilly: For those days with fierce winds, bundling up is key. Wear a thermal base layer under a chunky knit sweater, and top it with a down jacket or heavy parka. Add a thick scarf, wool hat, and thermal gloves. Fleece-lined leggings or weather-resistant pants will keep your legs warm, and tall insulated boots will provide extra protection against the cold.
If It’s Cold and Clear: Iceland’s crisp, sunny days are ideal for packing in adventures so you’ll want to layer for warmth while still feeling comfortable while active. A thermal base layer under a fleece sweater works perfectly. Pair this with insulated leggings or hiking trousers and waterproof ankle boots. Add a beanie, gloves, and sunglasses to protect yourself from the bright summer sun.
Additional Packing List for Iceland in September
Portable Charger: A portable charger is another must-have. With your phone constantly in use for navigation, photos, and making reservations, it’s easy for the battery to drain quickly. A power bank will ensure that you don’t run out of power when you need it most, especially during long days of sightseeing. Plus, how will you document your fabulous outfits in beautiful locations if your phone is dead?
Compact Backpack: Additionally, a lightweight backpack can come in handy for shopping or carrying extra items as you explore or hike. A spare bag will allow you to pick up some unique souvenirs or delicious pastries from local markets without worrying about your other belongings.
Reusable Water Bottle: Whether you’re hiking, resting, in the Blue Lagoon or anything in between, staying hydrated is a MUST! Drink up and minimize plastic waste in this beautiful country with a reusable water bottle.
Sunglasses: You may not think you’ll need sunglasses in September, but on those clear and cool days, the sun reflects off of ice, water, and more. And even if it isn’t super sunny while you visit, the reflection off of other elements can be dazzling. The sun is low in the sky at this point, so protect your eyes!
Final Thoughts: Iceland in September
Packing for Iceland doesn’t have to be stressful! Stick to the layering rule, bring waterproof gear, and don’t forget good shoes (seriously, wet feet are the worst). Whether you’re road-tripping, hiking, or just soaking in Reykjavik’s charm, these outfits will keep you comfortable and looking great.
