Weather & Climate in Iceland
The weather in Iceland is, on the whole, quite changeable and depends mostly on the tracks of the atmospheric depressions crossing the North Atlantic. The passage of a depression some distance south of Iceland causes relatively cold and dry weather, especially in southern districts, while one passing northeastward between Iceland and Greenland brings mild weather, moderately dry in the north. Coastal areas in Iceland tend to be windy—gales are common, especially in winter, but thunderstorms are extremely rare.
It is important to keep in mind that, at any time of year, the weather in Iceland can be unpredictable. A mild, sunny day can quickly turn into a tumultuous storm, complete with wind, rain and fog. In order to be comfortable throughout the trip, we highly recommend that you come prepared for changing conditions, as well as varying temperatures. Although not indicated in the local average temperature charts, it can become quite cold should we experience inclement weather, with temperatures sometimes dropping into the 30s.
