Best time of year for a holiday:
June to September present themselves as the best time to visit the volcanic island. Yet even during those months the average daily highs rarely venture beyond 14 °C (57°F).
If that does not scare you off, and it should not, you will be rewarded by an unforgettable experience. Iceland has a bit of a rough charme and you will certainly not be bored. The natural sights are simply great and the sunset probably some of the most impressive in the world.
The winter in Iceland can be rather cold and you should prepare accordingly. You can expect lots of snow and thus ideal conditions for skiing, for example. With more than 90 ski-lifts, the country is a real alternative for a somewhat different winter holiday. Enjoy!
