The climate of Iceland is usually much warmer than other Nordic countries. Particularly the southern and western areas are much milder than northern and easterly areas.
(However, this brings mild Atlantic air in contact with colder Arctic air resulting in a climate that is marked by frequent changes in weather and storminess. Furthermore this leads to more rainfall in the southern and western part than in the northern part of the island.)
The summer tourist season is from late May to early September. During the first half of this period the sun stays above the horizon for almost 24 hours and the interplay of light and shadows on mountains, lava fields and glaciers yield an ever changing landscape.
However, even during the middle of summer the sky is frequently cloudy or overcast and the sunshine does not warm the air much. Hence, during daytime, the air is usually cool (“refreshing” is the local euphemism) and cold during night time. Despite it being summer Iceland rarely sees many sunny days.

Iceland enjoys a cool temperate maritime climate thanks to the Gulf Stream, but the weather is known to change quickly and often. Icelanders have a saying: “there is no such thing as bad weather, just bad clothing.” No matter the season, visitors should always have wind and water resistant outerwear as well as extra thermal layers on hand before heading out on excursions.
As for winter, Iceland is not all covered by ice and snow as its name would suggest. In fact, outside of the higher altitudes or parts of North Iceland, snowfall rarely stays on the ground longer than a few days. Rain is more common, with October being the wettest month. Also, the cool northerly winds can be strong at times so we recommend an insulated or down jacket for winter visits.
