How to dress for Iceland's unpredictable weather
Dress in three distinct layers: a moisture-wicking base, an insulating mid-layer, and a completely waterproof/windproof outer shell. Never wear cotton, as it stays wet and cold, and always bring a hat and gloves regardless of the season.
- Choose your base layer. Wear thin merino wool or synthetic thermal tops and bottoms. Avoid cotton at all costs; if it gets wet from sweat or rain, it will not dry and will pull heat away from your body.
- Add an insulating mid-layer. Wear a fleece sweater or a lightweight down or synthetic 'puffy' jacket. This layer traps your body heat. Ensure it fits comfortably under your outer shell without feeling too bulky.
- Seal with a waterproof shell. Your outer layer must be a dedicated rain jacket and rain pants with a high waterproof rating (look for 10,000mm or higher). Windproof material is equally important as the wind in Iceland is relentless.
- Protect your extremities. Always pack a wool beanie that covers your ears and gloves that are windproof. Even in July, your hands will get cold during waterfall visits or glacier hikes.
- Can I just bring a big winter parka?
- Only if it is fully waterproof. Most heavy parkas are water-resistant but will soak through in Icelandic horizontal rain. A shell over a mid-layer is more versatile.
- Do I really need expensive hiking boots?
- Yes. The terrain is often rocky, uneven, and wet. You need a sturdy sole and ankle support to prevent injury on lava fields.
- Is an umbrella useful?
- No. The wind in Iceland is often strong enough to break umbrellas or turn them inside out within seconds.
