Cool off in Iceland: The perfect summer escape from scorching heatwaves

As Europe and North America sizzle under record-breaking summer heatwaves due to human-induced climate change, travelers are looking north, not just on the map, but for relief. If you’ve had enough of sweating through your city or melting on crowded beaches, we’ve got good news: Iceland is the coolest place to be in during summer. In this article, you will discover how easy it is to cool off in Iceland.

Welcome to a place where the breeze off the North Atlantic will have you reaching for a light jacket, where glaciers sparkle under the midnight sun, and where natural air-conditioning comes in the form of roaring waterfalls, misty fjords, and brisk mountain air. Iceland in summer isn’t just a destination—it’s a revelation. Remember, it’s easy to offset the carbon footprint of your trip to Iceland.

Iceland’s summer climate: a breath of fresh air

Let’s start with the numbers. While southern Europe sees temperatures soar into the 40s°C (that’s over 100°F), Iceland’s summer weather stays refreshingly mild. Average high temperatures in July and August typically range from 10 °C to 15°C (50°F to 59°F). Some of the warmer days might reach 20°C (68°F), but that’s practically sweater weather for most people coming from sweltering cities.
And it’s not just the temperature. Thanks to the oceanic climate and frequent breezes from the North Atlantic, Iceland’s air feels crisp and clean. You’ll be walking around energized, not sluggish from the heat. It’s the kind of weather that invites you to move, hike, explore, and breathe deeply.

Cool-down activities that are pure Iceland

Now that you’re not sweating through your shirt, what should you do in Iceland to enjoy the cool summer magic? Here’s a list of activities that pair perfectly with the fresh Icelandic air.

Whale watching with a sea breeze bonus

If you’re looking for a refreshing way to spend a summer day, hop on a whale watching boat and let the cool North Atlantic breeze do its thing. Whether you depart from Reykjavík, Húsavík, or Akureyri, you’ll be out on the open sea with crisp, salty air in your face—maybe even in a cozy over-suit that keeps you warm while you scan the horizon for humpbacks, minke whales, or even blue whales.

It’s one of the most peaceful yet thrilling experiences you can have in Iceland—and yes, the breeze out on the water is the kind that instantly clears your head (and your sinuses). I partner with Iceland’s top whale watching companies—Elding (in Akureyri and Reykjavik), North Sailing, Special Tours, and Whale Watching Hauganes—to bring our readers exclusive discount codes.

Walk on a glacier

Guided glacier hikes on places like Sólheimajökull or Vatnajökull are unforgettable. You’ll strap on crampons and walk across ancient blue ice, deep crevasses, and ice formations sculpted by time. The cool wind coming off the glacier? That’s natural air-con you won’t find anywhere else.

Chase waterfalls (and Feel the cool mist)

Waterfalls in Iceland don’t just offer stunning views—they give you that fresh spray of icy water that’s like nature’s face mist. Gullfoss, Dettifoss, Skógafoss, and Seljalandsfoss are summer favorites, but don’t miss lesser-known gems like Gljúfrabúi, Kvenufoss, or Dynjandi in the Westfjords. These are not just Instagram backdrops; they’re immersive, refreshing experiences.

Paddle through fjords or sail on the glacial lagoons

Sea kayaking in Ísafjörður or floating among icebergs at Jökulsárlón, a glacial lagoon, is an incredible way to enjoy the cool summer of Iceland.

Hike the Icelandic highlands

Trails like the Laugavegur trek or the Fimmvörðuháls hiking trail allow you to hike through snow patches, mossy lava fields, and past rivers. These highland hikes are a dream for anyone looking to stay active without overheating. Just make sure you are an experienced hiker and well prepared for long treks in the Icelandic highlands. The weather can get rough up there. Sometimes, you might find yourself hiking in Iceland when the weather is s*it!

Bonus: You’ll Sleep Better

Here’s something rarely mentioned but hugely appreciated by visitors: sleeping in Iceland during summer is bliss. With temperatures staying cool, even at night, you can sleep soundly under a duvet instead of tossing and turning in an overheated hotel room. NB: Icelandic homes rarely have air conditioning; we don’t need that stuff!
