Iceland weather and climate seasons


What is Iceland Weather Like?


There is an old saying in Iceland: ‘You could experience all four seasons in a day if you’re lucky’. It’s a phrase often used by Icelanders to describe how volatile the weather can be during some periods of the year, and it is actually true! You can experience warm sunshine, heavy rain, peaceful snow, and hard wind, all in the same spot and in a single day!


Iceland Average Temperature


One of the best things about Iceland weather is the fact that the temperature never gets too warm or too cold. Iceland's average temperature in the winter months usually ranges from around -10 °C to 0 °C, while Iceland's average temperature in the summer can vary between 2°C and 20°C.


If you’re equipped with clothing that can withstand wind and rain, you won’t have any major issues dealing with these temperatures. If you don't know what clothes to wear in Iceland, make sure you check our guide out!


Iceland Climate


The Icelandic climate in general is, in fact, far milder than most people believe. This relatively temperate climate is all down to the warm ocean currents of the Gulf Stream a the volcanic activity under the island.

Iceland Weather by Season


Just like most other countries, the weather in Iceland changes by the season, but it might look different to what you are used to. Due to where Iceland is located on the map, they have different characteristics of their seasonal weather. The Iceland weather by month won’t correspond to what most people in the Northern Hemisphere are used to and is determined by the harsh Iceland climate.


Spring Weather in Iceland


There's something you need to know before traveling to Iceland in Spring: officially speaking, Iceland doesn’t have a spring season. Instead, its climate is often talked about in terms of just winter and summer. During what most of the Northern Hemisphere would consider springtime, the Iceland spring weather still feels very wintery in Iceland.


Relatively speaking, however, the spring in Iceland is nothing short of magical, as it is the time when nature goes from dormant to awake. With the roaring waterfalls, it is as if the mountains themselves are coming alive.


Summer Weather in Iceland


From June to August Iceland experiences its summertime. This is also the tourist high season and the best time of year for hiring a camper van in Iceland. Even though this is summer, Iceland’s notoriously changeable Iceland summer weather can still throw many a curveball. Days can feel cold if the wind blows from the north and there may well be plenty of rainy days.


Autumn/Fall Weather in Iceland


Again, this is a crossover season and doesn’t really exist in Iceland. Summer-like weather conditions can continue well into September. At the same time, Autumnal conditions can start to show from as early as late August. The Iceland fall weather is like spring in reverse. Rain and wind are starting to build up during this season, but don’t bother with an umbrella unless you want to re-enact that famous Mary Poppins scene.


Winter Weather in Iceland


Iceland's winter weather stays for a long time with real winter wonderland magic. The lowest ever temperature recorded was in the winter of 2018 when the mercury dropped to minus 38°C! But this was an extreme occurrence. The temperatures can go down to -20°C regularly in the northern part of Iceland but stay close to 0°C in the south.


The Iceland weather in winter is snowy and cold with long nights. In the depths of winter, the sun never really rises. Instead, there is a beautiful twilight that turns the landscape golden if the skies are clear. This is the time of year when the Northern Lights in Iceland can be most frequently spotted.
