Iceland, located in the North Atlantic, is a dream destination for nature and adventure lovers. Between its volcanic landscapes, imposing glaciers and spectacular fjords, the island offers an ideal setting for hikers. However, its unpredictable and variable climate requires adequate preparation in terms of clothing to make the most of your stay. Whether you're heading there in winter or summer, here are our tips on how to dress in Iceland for a comfortable and enjoyable experience.
Iceland's climate
Iceland has a temperate oceanic climate, influenced by cold ocean currents and polar winds. The weather can change rapidly, with frequent alternations of rain, wind and sunshine, making proper clothing preparation essential.
In winter, temperatures average around -5°C, with lows reaching -15°C. The island is covered in snow and ice, and conditions can be tough for hikers. In summer, temperatures are milder, averaging around 12°C, but the climate can still be cool and windy, with a risk of rain.
The best time to explore Iceland is therefore between April and September, when the weather is drier and you can fully enjoy the scenery without too much harsh weather. However, winter should not be overlooked, especially for those who wish to see the northern lights and explore the glaciers.
Essential clothing for your trip to Iceland
1. Thermal base layers
When heading to Iceland, the first layer is crucial for staying warm. A merino wool base layer or technical fabrics such as bamboo carbon is ideal for regulating your body temperature and wicking away sweat while keeping you warm. It is essential to choose base layers that manage moisture and provide maximum insulation, especially in winter when temperatures can get extremely cold.
2. Fleece jacket and windproof
As Iceland is particularly exposed to the wind, a fleece jacket as a mid-layer is essential. It provides good thermal insulation while remaining lightweight and breathable. To complete your outfit, also bring a windproof and waterproof jacket, particularly in winter or during the rainy season. A jacket with a waterproofing rating of 10,000 Schmerbers will offer sufficient protection against the elements, while being breathable enough to prevent excessive moisture build-up.
3. Sturdy hiking shoes
Hiking in Iceland often involves rocky, muddy or snowy terrain. A good pair of hiking shoes is therefore essential. Choose water-resistant models with excellent grip to prevent slipping, and good ankle protection to avoid injuries. Don't forget to pack hiking socks in wool or synthetic materials to keep your feet dry and warm.
4. Accessories for wind and cold
To protect yourself effectively against cold wind and extreme weather conditions, pack gloves, a beanie or a cap and a scarf. These accessories will help you retain body heat and shield yourself from the elements, especially during hikes at altitude or near the coast, where the wind can be particularly strong.
5. Waterproof clothing for rain
As Iceland is known for its frequent rainfall, waterproof clothing is an absolute must. A lightweight, packable rain jacket is easy to carry and will protect you from sudden downpours. Waterproof trousers are also essential to prevent moisture from seeping in and chilling you during outdoor activities. Opt for stretch and breathable garments to avoid discomfort while on the move.
6. Lightweight and breathable clothing for summer
In summer, although temperatures are milder, the climate can still be cool and windy. Pack lightweight and breathable clothing such as t-shirts in technical fabrics (for example organic cotton or quick-drying synthetic materials), as well as long-sleeved shirts to protect yourself from the sun and insects. A fleece gilet or zip-up jacket will also come in handy to give you a bit of warmth without weighing down your pack.
7. Mosquito protection
In summer, you may encounter mosquitoes, particularly around bodies of water. To avoid bites, you can opt for mosquito-repellent treated clothing. These garments are impregnated with permethrin, an effective insect repellent. You can also use Activ'Dry fabric, made from chitin, a natural repellent that provides continuous protection without the need to reapply sprays or lotions.
Other practical tips for dressing in Iceland
- Swimwear and towel: Don't miss the chance to enjoy Iceland's hot springs or swimming pools. A swimsuit and towel are therefore essential, even in winter, as some outdoor pools remain pleasantly warm.
- Eye mask: In summer, with the continuous daylight seasons, an eye mask can be useful if you struggle to sleep in the light. Bear in mind that night lasts barely 4 to 5 hours in June and July, which can disrupt your sleep cycle.
Dressing for the season
Summer trip
In summer, the key is to stay light and adaptable to temperature changes. Prepare for longer days, but also rapid weather shifts. Pack lightweight and compact clothing, as well as extra layers to protect yourself from wind and rain. A lightweight waterproof jacket is ideal, as are breathable hiking socks to prevent blisters.
Winter trip
In winter, prioritise warm clothing, particularly layers that insulate you well from the cold. The three-layer technique remains essential: a thermal base layer, an insulating mid-layer such as a fleece or lightweight down jacket, and a waterproof outer layer to protect you from the elements. Don't forget to pack warm accessories such as gloves, a beanie and thermal socks.
With these practical tips, you'll be ready to take on Iceland's varied weather conditions and make the most of your stay. Make sure you pack clothing suited to every situation, focusing on layering for maximum protection.
