The weather in Iceland is so unique that it deserves a special mention. Iceland is one of the few countries where you can experience all the seasons in one day. In fact, it changes so quickly that Icelanders even have a joke about it: "Don't like the weather? Just wait 5 minutes!"

The most distinct element of Icelandic weather is undoubtedly the wind. The fact that the Icelandic language has 156 words to describe the wind says something about its importance. From logn (calm wind) and gola (gentle breeze), to rok (gale) and fárviðri (storm), Icelandic wind is truly something to experience!

So, what is the weather in Iceland?

Weather in Iceland by Month

Iceland has two distinctive seasons - summer and winter. During the summer, the Midnight Sun causes light and brightness round the clock, and during the winter, the wonderful Northern Lights light up the dark sky.

Within each season, there are months, each with its unique features. Since each is different, the best month to go to Iceland will depend on what you're looking for. Here we will break down the weather in Iceland by each month of the year.
