Iceland weather overview

In Iceland you can have fun but it is almost always in spite of the weather; not surprising when you consider that Iceland lies at the heart of the Atlantic's stormiest region. The warm Gulf Stream keeps winters mild on lower ground but the island lies right in the path of Atlantic depressions.

Be prepared for anything here especially strong winds: a day can start sunny, turn drizzly, revert back to brilliant sunshine and end with snow.

What to pack for Iceland weather

Your best bet is to layer up with light clothing which can be supplemented with woollens. Take heavier clothes for the winter, and always go prepared for rain.
