What is the Weather Like in Iceland


It is incredibly unpredictable and can easily go from a calm sunny day to a raging storm that makes you wonder if the entire house is going to blow away. This is due to the Iceland climate and can vary greatly depending on where you are in the country. Most of the time, though, the Iceland weather year-round will be a little cold, likely windy and with plenty of clouds.


The Weather in Reykjavik


Arriving in Iceland, Reykjavik is the first stop you’ll make after the airport and the base of operations for your adventures. Reykjavik is a coastal city and the weather acts accordingly. You often have a wind blowing through the streets (often light), and the temperatures are quite mild.


The Weather in North Iceland


As you might think, the northern temperature in Iceland is quite cold compared to the other parts of the country. Visiting the north in the summer can even be fairly cold, and you should remember to pack warm clothing if you go here, regardless of the season.


The Weather in East Iceland


East Iceland is perfect if you want to experience beautiful nature without being bothered by other tourists. It’s a scarcely dense part of the country and can offer you the full range of the Iceland weather and temperature spectrum. Sometimes every type of weather in a single day!

The Weather in South Iceland


Being the most tourist dense part of the island, the Iceland weather in the southern parts is usually regarded as mild and easy-going compared to the rest of the country. You can get the bulk of experiences in this part of Iceland, and this is where you should look for the best deal to rent a luxury car Iceland has to offer.


The Weather in West Iceland


The wind blows hard in the west. The Iceland climate is governed by the warmth from the core of the island clashing with the arctic cold of the sea. This results in heavy winds, rain, and snow all year, and the temperatures reflect this type of Iceland weather quite well.

Iceland Weather and Temperatures in January


The weather in Iceland in January is in the middle of winter, just before the strong winds and rain is setting in. Make sure to keep an eye on the weather forecast, since the weather can go from very sunny and seemingly warm to biting cold and blow-you-away-windy.

In January, it’s also a good idea to come prepared with some sunscreen (believe it or not), since the snow reflects the sun’s rays and you can actually get a sunburn when you’re out hiking in the snow.

Iceland Weather in January in a nutshell:

  • Average high temperature: 2°C

  • Average low temperature: -2°C

  • Average rainfall: 100mm

  • Average sunlight: 5 hours

What's the Best Season to Visit Iceland?


Now you’ve gone through extensive information regarding the Iceland weather, and you can see that when is the best time to visit Iceland depends on the type of activities you’d like to try.


If you want to visit all the tourist attractions in their glory, late or early summer is the best option if you want some privacy and high summer is best if other tourists don’t bother you.


If you’re out to watch the northern lights or experience that raw, northern feeling, then winter will be your best bet. Remember to visit the northern part of Iceland for a good chance of spotting the northern lights.


In general, the spring is great for catching the waterfalls in all their glory, but the fall/autumn is rarely a good option for a vacation.
