Decoding August Temperatures: A Deeper Dive
So, what kind of temperatures can you actually expect in Iceland in August? Let’s break it down.
Average Highs and Lows
On a typical day in August, you’re likely to see daytime highs hovering around 10 to 15°C (50 to 59°F). Keep in mind that these are averages. The highest temperature ever recorded in Iceland was 30.5°C (87°F) way back in 1939, but that’s definitely an extreme outlier!
At night, temperatures tend to dip, with average lows ranging from 7 to 9°C (45 to 48°F).
Factors Influencing Temperature
Several factors play a role in shaping Iceland’s August temperatures:
- Ocean currents: The Gulf Stream has a significant impact on Iceland’s climate, making it considerably milder than other locations at similar latitudes.
- Altitude: As you might expect, higher altitudes, particularly in the Icelandic Highlands, tend to be cooler.
- Wind: Wind chill can be a factor, making temperatures feel colder than they actually are, even on days that might otherwise seem relatively mild.

While August in Iceland is relatively mild, you should still expect some rain during your visit. Here’s what to know about rainfall and precipitation.
Average rainy days
On average, you can expect around 8 to 12 days of rain in Iceland during the month of August. Most of the time, it’ll be light showers, but heavier rainfall is possible from time to time.
Regional variations in rainfall
The amount of rain you’ll experience can vary based on where you are in Iceland.
- Southern coast: The southern coast tends to get more rain because it’s more exposed to weather systems that move across the Atlantic.
- Northern regions: The northern regions tend to be drier than the south.
- Highlands: If you’re planning to visit the highlands, expect more precipitation, including the possibility of snow at higher elevations.
Regional Weather Variations in August
Iceland’s weather can vary significantly from one region to another, even in August. Here’s a breakdown of what you might expect in different parts of the country:
Reykjavík and Southwest Iceland
This area tends to have milder temperatures compared to other regions, but be prepared for rain showers. The weather can change quickly, so pack layers.
- Blue Lagoon: The geothermal waters are enjoyable even in light rain, but the air can feel cool when you get out, so have a warm robe ready.
- Golden Circle: The weather can shift rapidly. Pack for sun, rain, and wind.
North Iceland (Akureyri)
Generally cooler than the south, North Iceland can experience more sunshine, but also more unpredictable weather. Be prepared for anything.
- Lake Mývatn: Pack layers as temperatures can fluctuate throughout the day.
- Whale watching tours: Check weather and sea conditions before booking a tour. Tours may be canceled due to high winds or rough seas.
South Coast and Vík
The South Coast tends to be milder, but it also has a higher chance of rainfall, and strong winds are common.
- Waterfalls (Seljalandsfoss, Skógafoss): Waterproof gear is essential. You’ll get wet from the mist, even if it’s not raining.
- Black sand beaches: Be aware of sneaker waves. These unpredictable waves can be dangerous, so stay a safe distance from the water’s edge.
Highlands
The Highlands are the coldest region and have the most unpredictable weather. You might even encounter snow in August.
- Travel considerations: The Highlands are only accessible by 4WD vehicles. Guided tours are highly recommended, as the terrain can be challenging, and weather conditions can change rapidly.
