Summer in Iceland is just around the corner, so I’m diving into a topic that comes up a lot—how to dress and pack for summer in Iceland.Whether you're planning to explore glaciers, wander lava fields, hike to waterfalls, or just soak in the geothermal goodness, dressing right for Iceland’s unpredictable summer weather is key to staying warm, dry, and comfortable.
Summer Months in Iceland
First things first, let’s talk about when summer happens in Iceland. While summer technically runs from June through August, things start to warm up by mid-May and stay fairly mild through early September.But don’t let the word “summer” fool you. Unlike tropical destinations, Icelandic summer is more about long daylight hours than high temperatures.
Average Summer Temperatures
On average, summer temperatures in Iceland range from 45°F to 60°F (that’s about 7°C to 15°C). On sunny days, it can feel warmer—especially if you're hiking or layering correctly—but the wind and rain can sneak up on you. So, the key word here is layers!
What Are Layers, and Why Do They Matter?
If you’re not familiar with the concept of layering clothes, here’s a quick breakdown below with my recommendations:

The Base Layer
This is your first layer, the one closest to your skin. It should be moisture-wicking, meaning it pulls sweat away from your body so you stay dry. Think lightweight wool or synthetic materials—not cotton. A good base layer helps regulate your body temperature, even when you’re active.My recommendation for a Base Layer:* Ljosfjöll Hoodie – Lightweight, breathable, and a perfect first layer against your skin. Keeps you warm without overheating.
The Mid Layer

The mid layer provides insulation. It traps heat to keep you warm, and you can add or remove this layer depending on the temperature. Fleece, wool sweaters, or insulated vests work great here. Think of this as your “cozy” layer.My recommendations for a Mid Layer:* Kaldi Off White Sweater – This one is a classic Icelandic wool-style mid-layer. It’s stylish, warm, and breathable.* Tindur Pelican Jacket – A technical shearling mid-layer that works well alone or under a shell.* Kellir Down Vest – A lightweight puffer vest that adds warmth without bulk.* Kria Hybrid Hoodie – Water-resistant, warm, and highly packable. Perfect for high-energy hikes or windy coastlines.
The Outer Layer

This layer protects you from the elements—wind, rain, or even sleet (yes, even in summer). A high-quality shell jacket and weather-resistant pants will block wind and repel water, helping you stay dry no matter what Iceland throws your way.My recommendations for an Outer Layer:* Snæfell  Shell Jacket – Fully waterproof and windproof. A must-have. I’ve used it on rainy glacier hikes and it held up beautifully.* Borgir Women’...
