August is the perfect month to visit Iceland. The weather is more stable than in other seasons, and the temperatures are warmer. However, you’re never safe from the infamous changing Icelandic weather.

Key Takeaways

  • August in Iceland features mild and stable weather, with daytime temperatures around 14-15°C (57-59°F) and cooler nights, though conditions can change rapidly.
  • Pack layered clothing and waterproof gear, including thermal layers, fleece tops, a waterproof jacket, long pants, hiking shoes, and a swimsuit for the varying weather.
  • August is perfect for outdoor activities like hiking and whale watching. Due to tourist demand, plan and book in advance, and regularly check weather and road conditions.

Since Iceland’s main attractions are outdoors, understanding the Icelandic climate in advance is key to planning your trip properly.

In this guide, we will help you understand what to expect about the weather when visiting Iceland in August. We will also detail things to consider when packing your bags, and what activities are perfect for this month.

Understanding Iceland’s Weather in August

The weather in Iceland changes quite a lot from one season to another, even at a moment's notice within the same day.

Although there is no bad season or time to visit Iceland, August might be one of the best options. It's one of the warmest and most stable periods for the weather, and you can get up to 16 or 17 daylight hours thanks to the Midnight Sun phenomenon.

In fact, if you are planning to travel to our great country for the first time, summer is a fantastic time to do it. The softer weather and the extended hours of sunlight will make it easier for you to enjoy everything that this country has to offer—which is a lot!

What is The Average Temperature in August in Iceland?

In August, the temperature is mild during the day and cool at night, but never reaching freezing temperatures as one might expect.

It's important to point out that, although Iceland does not have a vast territory, the weather is not the same throughout the whole country.

The Southern Coast normally experiences higher temperatures than the North area, while the coldest region is the Central Highlands. However, the differences are not as high as in other countries.

In general, during August, the average maximum temperature in the country oscillates between 14 and 15 °C (57.2 to 59 °F). At night, it drops to around 8 or 9 °C (46.4 to 48.2 °F). Warm summer days can see the temperature rise to 20-25 °C (68 to 77 °F).

The highest temperature ever registered in Iceland was in 1939, when a record-high 30.5 °C (87 °F) was recorded in the Eastern Fjords.

Please be aware that the weather in Iceland, even in August, is constantly changing and is unpredictable. You may wake up under heavy rain just to find out that the sun is shining and there are no clouds on the horizon by the time you finish your morning coffee.

How Much Does it Rain in August in Iceland?

Iceland’s location in the North Atlantic Ocean is what makes the weather there so peculiar. Even though it's not as cold as one might expect, its unique position leaves the island exposed to wind and rain.

Although it's a rainy country in general, it’s not as rainy as other places further south and as exposed to the Atlantic Ocean as Iceland is. In fact, Iceland sees less rain in summer than Scotland, for instance.

Rain Patterns in August by Region

As you can imagine, there is no golden rule for predicting the rain. As with temperature, the amount of rain and the number of rainy days differ in different parts of the country.

The west and south coasts, more exposed to the changes of weather in the Atlantic, receive the most amount of rain. In contrast, the north, which experiences colder temperatures in general, and in August as well, is drier.

As mentioned before, this can all change at a moment’s notice, and it's quite common to experience different “seasons” on the same day. But, in general, August is a relatively dry month, with an average of 8 to 12 days of rain.

As the weather is so unpredictable, it's a good idea to carry a rain jacket or rain pants with you to help you deal with these sudden changes.

Even though it can occur, it's very unlikely to have snow in August. However, some areas can remain covered in snow from previous months, especially in the Central Highlands.

The Weather in Different Regions of Iceland in August

As you already know, the weather may change depending on the region of Iceland you are in. And even there, it can change depending on the day, or even the hour!

The best way to be one step ahead and plan your daily activities is to check the official website of the Icelandic Met Office.

They provide accurate forecasts for different regions.

August Weather in Reykjavík

Reykjavík, the capital of Iceland, is the northernmost capital of a sovereign nation in the world. It's located in the southwest region of the country. This area is characterized for its mild temperatures, but also a wetter and windier weather than the rest of the island.

August is, alongside July, the driest month of the year, making it a great time to visit the Icelandic capital.

The temperature during this month fluctuates between 10 and 15 °C (50 to 59 °F), with a couple of degrees up and down. It very rarely goes over 20 °C (68 °F). However, its location makes it prone to winds coming from the ocean, which may create the perception that it's colder than it actually is.


As soon as you move around the country from the capital, you will notice changes in temperature and other climatic elements.

South Iceland Weather in August

If you leave Reykjavík and start going south along the coast, you will soon realize that the temperature rises a bit. This area, as it happens in the capital, is exposed to winds and rain, but not as much in August as in other months throughout the year.

North Iceland weather in August

The north of Iceland is the driest but also the coldest part of the country, except for the Central Highlands. The main city in the region is Akureyri. The temperature here is lower than in Reykjavík, but the difference is not that big during the summer months. The chances of rain are also lower than in other parts of the island.

The Central Highlands in August

One of Iceland's most notorious natural attractions is the Central Highlands. This area covers most of the country's interior and includes some of the island's best-known landscapes, such as Landmannalaugar, Langjökull Glacier, or Hveravellir Nature Reserve.

Some parts of the Highlands are difficult to access and are only open to the public during the summer. In other seasons, the heavy snow or other climatic events force the authorities to close some roads in the area. For this reason, August is the perfect moment to discover this area of Iceland.

Still, If you are planning on visiting the Highlands, remember that the weather here is colder than in the lower regions. The temperature can drop considerably here, as there are many mountains in the area, with peaks reaching between 1,000 and 2,000 meters high.

What to Pack For The Weather in August

Careful planning can make a huge difference in your travel experience when going to Iceland. You don't need to take a huge suitcase full of different clothes for all kinds of weather—you just need to be practical!

Layers and waterproof clothing will be your best allies in dealing with different climatic situations. Wearing different thin layers is better than a shirt and a thick coat.

A waterproof jacket and pants can also make a difference. Although August is relatively dry, rain is common and can happen suddenly.

It's advisable to always carry a small backpack with you. This way you can put on or take off clothing that helps you fight the constant changes in the weather. Fleece is a good material to consider.

Things to pack:

  • Thermal clothing (base layer).
  • Fleece tops.
  • Waterproof jacket/pants.
  • Long pants.
  • Shorts.
  • Hiking or trail shoes.
  • Swimsuit.
