What to Wear in Reykjavik in May: Packing Tips for Spring

The Layering Strategy: Base, Mid, and Shell Layers

Layering is the only reliable way to dress in Reykjavik in May, because conditions change so often within a single day. Each layer contributes something different: a base layer manages moisture, a mid layer traps heat, and a shell blocks wind and rain. Choose each piece with an eye to how easily it can be added or removed.

This three-layer system works for nearly everything you'll do, whether you're strolling the old town, hiking a coastal trail, or taking a Golden Circle tour. The same principle applies to your legs – thermal bottoms under waterproof pants when you need them, or just durable trousers for city days.

Base Layer: Merino Wool Is Your Best Friend

For your base layer, merino wool is the standout choice because it keeps you warm and dry without feeling heavy. Unlike cotton, merino wicks moisture away from your skin and continues to insulate even when damp, so you stay comfortable during light activity or sudden rain showers.

Pack a couple of merino long-sleeve tops and, if you tend to get cold, a pair of merino leggings or thermal bottoms to wear under your trousers. Because merino resists odours, you can rotate a few pieces over a full week without excessive laundry.

Mid Layer: Fleece, Wool Sweaters, and the Lopapeysa

Your mid layer provides the insulation that keeps you warm when the mercury drops. A fleece jacket or a wool sweater works perfectly, and some travellers invest in a lopapeysa – a traditional Icelandic sweater woven from local sheep's wool. It's warm, water-resistant to a degree, and doubles as a distinctive keepsake.

Lopapeysa sweaters are widely sold in Reykjavik, and while they are an editorial suggestion rather than a requirement, they make a practical and memorable purchase. If you'd prefer to buy one during your trip, you'll find them in many souvenir and design shops across the city.

Shell Layer: Waterproof and Windproof Jackets

Your outer shell is your defence against Iceland's frequent wind and rain, so it needs to be both waterproof and windproof. A quality rain jacket with a hood is essential – it keeps you dry during showers and blocks the wind that can cut right through other layers.

Some travellers add a packable down or synthetic insulated jacket as an extra layer for cool evenings. Because such jackets compress small, they're easy to stash in a daypack and pull out when the temperature drops after sunset.

Bottoms: Jeans vs. Hiking Pants and the Rain Pants Question

For sightseeing around Reykjavik, jeans are a common choice, but they become heavy and uncomfortable when wet and take a long time to dry. For outdoor excursions or any activity where rain is likely, lightweight hiking trousers made from quick-drying synthetic fabric are a smarter option.

Waterproof rain pants are worth the extra luggage space if you plan on visiting waterfalls or spending long hours outside. They slip over your regular trousers and provide an effective barrier against rain and wind, making them a key piece for spring in Iceland.

Footwear: Waterproof Shoes, Boots, and Traction

Your footwear needs to handle damp, uneven terrain, so waterproof boots with good grip are the top recommendation for May. They'll keep your feet dry on rain-soaked streets and provide traction if you encounter mud or the occasional icy patch on trails.

For easier city days, a pair of waterproof walking shoes or trainers will serve you well, offering comfort without the bulk of full hiking boots. Remember to bring several pairs of moisture-wicking socks – wool-rich hiking socks are ideal – since dry feet are essential for staying warm.

Accessories for Unpredictable Days: Hat, Gloves, Scarf, and Sunglasses

Even in May, a warm hat and gloves belong in your daypack because the wind can make you feel chilled quickly. A lightweight beanie or a brimmed hat that covers your ears adds a huge difference in comfort when the temperature dips.

A scarf or neck gaiter is also handy, and you'll appreciate sunglasses on the bright, clear days when the sun reflects off wet pavement and snow patches still linger. These accessories are small and weigh little, so you have no excuse to leave them behind.

Evening Wear in Reykjavik: Smart Casual for Dining and Nightlife

For evenings out in Reykjavik, the dress code is generally smart casual, according to local travel experts. That means you can dress up slightly for dinner or a night out, but you don't need formal attire.

Consider packing a pair of dark jeans or trousers, a nicer sweater or blouse, and a versatile jacket that can transition from day to night. Since temperatures stay cool in the evenings, you'll want to keep your merino base layer underneath for extra warmth.

Sample Packing List for a Week in Reykjavik

For a one-week trip, aim to pack around five outfits that you can mix and match. Here’s a practical list to build from: two or three merino base layer tops, one pair of merino leggings, a fleece jacket, a wool sweater (or buy a lopapeysa in Reykjavik), a waterproof jacket, a packable insulated jacket, two pairs of hiking trousers, one pair of jeans, and one pair of rain pants.

Footwear and accessories complete the kit: waterproof hiking boots, waterproof walking shoes or sturdy trainers, several pairs of wool-blend hiking socks, a warm hat, gloves, a scarf or neck gaiter, and sunglasses. This combination keeps you prepared for the full range of May conditions without overloading your luggage.

What to Leave Behind

Leave the summer wardrobe at home – shorts, sandals, and thin t-shirts will likely stay buried in your suitcase. Even on the warmest May days, temperatures rarely climb high enough for such clothing, and the wind can make even a mild day feel cold.

Also skip heavy cotton items like sweatshirts or denim jackets that soak up moisture and take forever to dry. As a rule, if an item is not comfortable getting wet, it may not be worth the luggage space for a May visit.

Before You Go: Check the Forecast

A few days before departure, check the extended weather forecast for Reykjavik to gauge whether you'll need extra insulation for a chilly spell. Keep in mind that forecasts can change quickly in Iceland, so it's smart to have your layer system ready regardless of the prediction.
