Weather in Iceland

Wondering what weather to expect in Iceland? Knowing what Iceland’s climate is like and what Iceland average temperatures you might experience during your trip is key to planning your vacation wardrobe and itinerary. 

Let’s take a look through a general overview of the climate and weather in Iceland, plus an in-depth exploration of the typical Iceland average temperatures in different seasons throughout the year.

What’s Iceland’s Weather Like? 

Iceland’s climate is an oceanic climate with cool summers and relatively mild winters, which makes the island’s weather relatively mild for its location just below the Arctic Circle. This is due to the warm currents of the Gulf Stream, which mix with cold Arctic air, causing frequent fluctuations in Iceland’s weather. 

The famously changeable weather in Iceland means wearing waterproof outer layers is an essential when heading out on a day trip in Iceland, no matter what time of year you’re visiting. Iceland’s southern region is warmer and wetter than the north, with the north experiencing longer and colder winters.

What’s the Weather Like in Reykjavík? 

Iceland’s beautiful capital city, Reykjavík, is one of the coldest and cloudiest capitals in the world. Located on the coast of southwest Iceland, Reykjavík receives lots of rain (South Iceland receives more rain than North Iceland in general). The rainiest month of the year is January, with an average of 50mm of rain. 

Reykjavík is a pretty windy city, so we definitely recommend wrapping up warm. Summers are generally mild and fairly short, whereas winter lasts much longer and can be very cold. There can also be storms with strong winds and extreme weather, including high rainfall and snowfall.

When is Summer in Iceland? 

From around June to August is summer in Iceland, although Iceland temperatures usually start to rise around May and stay warm until September. True summer is between June and August, with July being the warmest month in Iceland. How Warm Does it Get in Iceland?

Shoulder Season Weather in Iceland (Spring and Fall) 

The shoulder seasons of spring and fall aren’t as defined as in other countries. As the island undergoes the yearly transition from winter to spring and summer to fall, Iceland’s weather can be even more changeable than usual. 

You’re more likely to experience a mixture of cool and warm days during both spring and fall, with some rainy, clear, windy and sunny days. It’s also not uncommon to experience all these different weather conditions during one day!

Spring Weather in Iceland 

A short season beginning in around March and lasting until May, spring sees beautiful flora flourishing across the island and migrating birds returning to the island, such as Iceland’s iconic puffins. 

Although spring in Iceland is warmer than winter, Iceland’s spring is still relatively cold, with the average temperature remaining around 3ºC (37ºF). Daylight hours range from 16 to 18 hours in South Iceland and 12 to 17 hours in North Iceland.

How to Dress Appropriately For Iceland’s Weather 

Layering is the key rule you need to know in order to dress well for Iceland’s weather. That’s because the weather can be very changeable, so the most experienced travelers are prepared to potentially experience all four seasons in one day!

You’ll need a warm and waterproof outer layer, plus thermal base layers if you’re planning to visit during any of the winter months. We recommend wearing waterproof walking shoes or hiking boots as well, which will come in handy for exploring the various natural spaces all around our beautiful country.

Local Weather Forecasts in Iceland 

One important point to note about Iceland’s weather is that it could be sunny in one town, but rainy and windy in the next town over. The constant fluctuation of the weather in Iceland means it’s a good idea to look up the local Iceland weather forecast for the area you’re planning to visit and check this regularly for information on up-to-date weather conditions.  

Another important thing to check before heading out on your day trip across the island is the current road conditions in Iceland, which will tell you which roads are closed and currently unsafe to drive on due to harsh weather conditions – usually snow and/or ice. 

Certain roads are actually closed at specific times of the year, such as the mountainous F-roads in the Icelandic Highlands, which are inaccessible during winter, fall and spring. If you want to travel to the beautifully wild Highlands, you’ll need to plan your Iceland vacation for the summer months.
