Iceland, located in the northern Atlantic, is a dream destination for nature and adventure enthusiasts. Between its volcanic landscapes, imposing glaciers and spectacular fjords, the island offers an ideal setting for hikers. However, its unpredictable and variable climate requires careful clothing preparation to make the most of your stay. Whether you're travelling 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 quickly, with frequent shifts between rain, wind and sunshine, so choosing the right clothing is essential.
In winter, temperatures average around -5°C, with peaks that can reach -15°C. The island is covered in snow and ice, and conditions can be tough for hikers. In summer, temperatures are milder, hovering 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 landscapes without too much climatic hardship. However, winter should not be overlooked, especially for those who want to see the northern lights and explore the glaciers.
Essential clothing for your trip to Iceland
1. Thermal underwear
When travelling to Iceland, your first layer is crucial for staying warm. A merino wool thermal base layer or one made from technical fabrics such as bamboo charcoal can help regulate your body temperature and wick away sweat while keeping you warm. Choose base layers that manage moisture and provide plenty of insulation, especially in winter when temperatures can drop very low.
2. Fleece jacket and windbreaker
Given how exposed Iceland is 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 boots
Hiking in Iceland often means crossing rocky, muddy or snowy ground, so a good pair of hiking boots is essential. Choose water-resistant boots with excellent grip to help prevent slips and good ankle protection to reduce the risk of injury. Pack hiking socks made from wool or synthetic fibres to keep your feet dry and warm.
4. Accessories for wind and cold
To protect yourself from cold wind and harsh weather, pack gloves, a beanie or cap, and a scarf. These accessories help you retain body heat and protect you from the elements, especially when hiking at altitude or near the coast, where winds can be particularly strong.
5. Waterproof rain clothing
Iceland is known for frequent rain, so waterproof clothing is essential. A lightweight, packable rain jacket is easy to carry and protects you from sudden showers. Waterproof trousers are also essential for keeping moisture out and preventing you from getting cold during outdoor activities. Choose stretch, breathable clothing for comfort 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 a zip-up jacket will also come in handy to add a little warmth without weighing down your pack.
7. Protection against midges
In summer, you may encounter midges, particularly around bodies of water. To avoid bites, you can opt for insect-repellent treated clothing. These garments are impregnated with permethrin, an effective insect repellent. You can also choose Activ'Dry fabric, made from chitin, a natural repellent that provides continuous protection without needing 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 public pools. A swimsuit and a towel are therefore essential, even in winter, as some outdoor pools remain pleasantly warm.
- Eye mask: In summer, with the midnight sun season, 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 travel
In summer, the key is to stay light and ready for temperature changes. Be prepared for longer days, but also rapid weather shifts. Bring lightweight and compact clothing, as well as extra layers to protect yourself from wind or rain. A lightweight waterproof jacket is ideal, as are breathable hiking socks to prevent blisters.
Winter travel
In winter, prioritise warm clothing, particularly layers that insulate you from the cold. The three-layer system remains essential: a thermal base layer, an insulating layer such as a fleece or a lightweight insulated jacket, and a waterproof outer layer to protect you from the weather. Pack warm accessories too, such as gloves, a beanie and thermal socks.
With these practical tips, you will be ready for Iceland’s varied weather conditions and able to make the most of your trip. Pack clothing for different conditions, focusing on layers for maximum protection.
