How is the Weather in Iceland in Summer?
When people think of Iceland, many imagine a land covered in snow and ice. But Iceland in summer is a wonderful surprise for visitors: endless daylight, lush green landscapes that look like another planet, and much milder weather than most expect.
In this article, we’ll explain what to expect from the Iceland weather in summer—temperatures, rain, wind—and what to pack to enjoy your adventure to the fullest. If you’re planning a trip between June and August, keep reading.
When is Summer in Iceland?
Icelandic summer officially begins at the end of April—on the first Thursday after April 18. In 2025, it was April 24; in 2026 it will be April 23; and in 2027, April 22. This day is called Sumardagurinn fyrsti in Icelandic, it means “First day of Summer”.
However, we don’t really feel summer until May or June, when the country transforms into a vibrant green paradise and the days grow longer and longer. Most people consider summer to last until the end of August, though early September can also be quite mild.
It’s the most popular time to visit Iceland, as many mountain roads (like the F-Roads) are only accessible in summer, allowing visitors to reach remote areas like Þórsmörk or Mælifell volcano.
What Is the Weather Like in Iceland in Summer?
One of the most common questions we get is: “Is it cold in Iceland in summer?”
The short answer: not as cold as you think, but it’s definitely not hot either.
Average Summer Temperatures
Average temperatures in summer range between 9°C and 15°C (48°F–59°F). On sunny, calm days, it can feel much warmer—sometimes up to 25°C (77°F). But remember: Iceland is famous for its microclimates. Weather can change in minutes, and wind or rain can make it feel colder than it actually is.
- June: 8°C to 14°C (46°F–57°F)
- July: 10°C to 15°C (50°F–59°F)
- August: 8°C to 14°C (46°F–57°F)
July is usually the warmest month, but there are no guarantees. It’s not uncommon to experience all four seasons in one day.
Does It Rain in Summer?
Yes, it rains—but not as much as in autumn or winter. The south of Iceland (where Katlatrack is based) tends to get more unstable weather than the north. Expect light, intermittent showers more often than heavy downpours.
Always bring a good waterproof jacket and don’t let the forecast discourage you: when it says “rain,” it often just means light drizzle that won’t ruin your plans.
Is It Windy in Summer?
Yes, wind is a year-round feature in Iceland. While it’s usually calmer in summer, it can still affect how cold it feels. A 12°C (53°F) day with wind might feel more like 5°C (41°F).
That’s why dressing in layers is essential.
Is There Snow in Summer?
For most of the country, there’s no snow in summer, except on glaciers. If you visit places like Mýrdalsjökull or Vatnajökull, you’ll still see ice and snow year-round, as they are massive glaciers. But you won’t find snow in towns or on main roads during the summer months.
How Much Daylight Is There in Summer?
One of the most magical things about Iceland in summer is the endless daylight.
From late May to early August, Iceland experiences what’s known as the midnight sun. In June, in places like Vík, the sun barely sets around midnight and rises again at about 3:00 a.m. Even during the “night,” the sky never goes completely dark.
This gives you more time to explore, hike, or take tours without worrying about losing daylight. Just be aware that sleeping can be tricky if you’re sensitive to light—bring a sleep mask just in case.
What to Wear in Iceland in Summer
Even though temperatures are mild compared to winter, the weather can still change quickly. Here’s what you should definitely pack for summer:
1. Waterproof outer layers
A good waterproof jacket and pants are essential. Rain can start at any time—and attractions like waterfalls can soak you in seconds!
2. Base layers
Bring thermal underwear or long-sleeve shirts made of merino wool or technical fabrics. They regulate your body temperature and dry quickly.
3. Fleece or light down jacket
Perfect for layering when temperatures drop. It’s always better to have an extra layer than to be cold.
4. Waterproof hiking boots
Even if you’re not hiking long distances, the terrain can be uneven, wet, and slippery. Dry feet are happy feet.
5. Hat, gloves, and light scarf
Yes, even in summer. Wind can be strong, especially near the coast or up in the highlands.
6. Sunglasses and sunscreen
Believe it or not, Icelandic sun can be strong—especially when it reflects off glaciers or the sea.
7. Swimsuit
Wait—what? Yes! Many visitors enjoy soaking in natural hot springs like the Blue Lagoon or Seljavallalaug. Don’t forget your towel!
Why Visit Iceland in Summer?
Open roads: Places like Landmannalaugar or Mælifell are only accessible in summer.
Ideal tour conditions: Glacier hikes, ice cave tours, and Super Jeep expeditions are easier and more comfortable in this season.
More daylight: You can explore for hours without worrying about sunset.
Active wildlife: Summer is the best time to see puffins, seals, and even whales.
Festivals and local life: Small towns come alive with concerts, cultural events, and local celebrations.
But keep in mind that Iceland in Summer Doesn’t Mean Tropical Weather!
While summer days can be pleasant, Iceland is not a beach destination—though we do have stunning black sand beaches! Keep in mind that even in July, it can get cold and rainy for several days in a row. The key is to come prepared and keep your expectations realistic.
A foggy, moody day might be perfect for exploring an ice cave above Katla volcano, while a sunny one is ideal for a Super Jeep tour to Þórsmörk or Þakgil.
Can You See the Northern Lights in Summer?
A very common question is: can you see the northern lights in summer in Iceland?
The answer is no. The sky doesn’t get dark enough for auroras to appear. Northern lights season starts in late August or September and runs through April.
Conclusion: Summer in Iceland Means Adventure—With Unpredictable Weather
The Iceland weather in summer can be mild and pleasant, but it’s still unpredictable. The secret to enjoying it? Come prepared, dress smart, and keep a flexible attitude.
If you love unique landscapes, fewer crowds on the trails, and long, bright days full of opportunity, Iceland in summer is the season for you.
