Packing for Iceland’s Unpredictable Weather

Dress in three distinct layers: a moisture-wicking base, an insulating mid-layer, and a completely waterproof outer shell. Expect to experience sun, wind, and rain within the same hour, and never rely on cotton, which stays wet and cold.

1. Build your base layer. Pack thermal tops and bottoms made of merino wool or synthetic materials. Avoid cotton entirely, as it loses heat-retaining properties once damp.
2. Choose your insulation. Bring a lightweight down or synthetic puffy jacket and a fleece or wool sweater. This allows you to add or remove warmth depending on the wind chill.
3. Prioritize a hard shell. Invest in a dedicated waterproof and windproof jacket and rain pants. 'Water-resistant' is not enough for Icelandic horizontal rain; look for taped seams and a high hydrostatic head rating.
4. Protect your extremities. Bring a warm beanie that covers your ears, waterproof gloves, and at least three pairs of thick wool socks. The wind in Iceland is the primary source of discomfort.
5. Footwear strategy. Wear sturdy, ankle-high waterproof hiking boots with a good grip. Break them in at home for at least 15 miles before your trip to prevent blisters on lava rock terrain.

Do I really need rain pants?

Yes. When the wind picks up, umbrellas are useless and will break. Rain pants are the only way to keep your legs dry during a waterfall visit or a hike.

Can I just wear sneakers?

Only if you stay strictly in Reykjavik. On any trail, glacier, or waterfall path, the terrain is uneven, slippery, and often muddy. Waterproof boots are a safety necessity.
