Iceland has a cold oceanic climate in its costal regions and a tundra climate up in the inland highlands. The southerly lowlands of the island average around 0 °C (32 °F) in winter, while the Highlands of Iceland tend to average around −10 °C (14 °F). The average July temperatures are around 10–13 °C (50–55 °F) with warm summer days reaching 20–25 °C (68–77 °F).
Weather in Iceland can change abruptly and change greatly from place to place so be prepared to pull layers on and off throughout the day. We have a saying in Iceland if you don’t like the weather just wait a minute.
- Layers,Layers,Layers. Use many thin, warm layers rather than a few thick layers.
- Dress for the appropriate activity level.
- Wear winter socks. Preferably wool or synthetic substitute.
- Use a good quality coat, parka, or jacket.
- Wear a base layer. A “base layer” is long johns, union suit, long underwear, or whatever can provide a warm, light base to your winter gear. Merino wool products are recognised as one of the best base layers available.
- Wear a hat.
- Wear gloves or mittens.
- Hand warmers can be useful.
- Wear more than one layer on your legs. Oddly, some people will wear five layers on their torso, and only one layer on the legs.
- Keep dry. Being wet will cause chill to set in more quickly than if you’re dry. Have waterproof or at least water resistant outer layers.
