Iceland in August: Weather, Tips & Kayaking
August is one of the best months to tour Iceland. It is officially the last summer month, and the weather in Iceland in August is glorious — with warm days (certainly by Iceland’s chilly standards) and lots of daylight. Iceland’s weather in August is perfect for summiting its volcanic peaks, hiking over glaciers, visiting national parks, marveling at cascading waterfalls, cruising along the country’s rugged coastline, and getting entertained by puffins squabbling and swimming in the sea. If you are lucky, you might even spot the first Northern Lights of the season, especially in the latter half of the month.

Why Visit Iceland in August


Without snow, Iceland’s roads are not slippery during August and all-mountain routes are open to travelers. If you are looking for things to do in Iceland in August, you will be spoilt for choice. Below are the top reasons why this is such a great time to visit Iceland.
- Open country: The whole of Iceland is accessible in August, including remote mountains that are closed throughout winter. This means that you can visit practically every corner of this beautiful land. Planning a comprehensive tour of Iceland? August is just the right month to do it.
- Hikers’ paradise: The unforgiving Icelandic winter puts most remote areas out of reach. However, come August, some of the most gorgeous parts of the country are open for trekking and hiking in Iceland.
- Festive mood: August is a month of festivals in Iceland. Thjódhhátidh, the country’s biggest outdoor festival with origins going back to the 19th century, takes place during this time of year. This celebration sees locals and visitors flock to the Westman Islands for a weekend of fireworks, bonfires, and concerts. There is also the Merchants Weekend celebration in North Iceland which features concerts, walking tours, museum visits, and, of course, shopping.
- Kayaking and snorkeling: With pleasant days and warm weather conditions, August is a lovely time for kayaking and snorkeling in Iceland. Iceland has quite a few snorkeling and diving spots that are truly breathtaking, like the space between two continental plates in the Silfra Fissure and Strytan, the only place in the world where recreational divers can reach underwater geothermal vents.
- Horse-riding through the countryside: Since you need not worry about cold, snow, or rain in August, this is an ideal month to enjoy the breathtaking Icelandic countryside from the back of a horse.
Where to go and what to do

The weather in Iceland in August is ideal for hiking and trekking tours, with even inaccessible mountain routes opening. Visit Vatnajökull National Park where the landscape is dominated by glaciers of the same name. The park has several lovely hiking trails and waterfalls. On the country’s south coast is the mysterious Jökulsárlón Glacier Lagoon, with its floating icebergs and seals. Nearby is the otherworldly landscape of Diamond Beach, where sheets of shining ice lie over black sand dunes. August is also a suitable time to discover the country’s central highlands and its rugged landscape, an area that is accessible only in summer. However, you might need a four-wheel drive to navigate rough stretches.
Another exceptional road trip is circling the ring road in the country’s north. Take a break along the way to check out the art galleries and cool cafés during your Akureyri tour, indulge in whale-watching in Húsavík, admire the striking landscapes of Lake Mývatn Nature Reserve and walk past the thick woods and pretty waterfalls of the Ásbyrgi Canyon.
What to bring

A warm temperature in August means that you can do away with down jackets and thick woolen outfits. T-shirts with a few clothes that can be worn in layers should do the job most of the time. However, since the weather can get unpredictable, we also suggest that you carry a raincoat along with you. A good pair of hiking shoes is a must, while a waterproof jacket will come in handy in case of a shower.
Given the pleasant weather and long days, it is no surprise that August is part of Iceland’s peak tourist season. Our travel experts can help you choose the right custom tour to Iceland in August. Look no further if you are planning on booking a trip to Iceland in August.
