Best things to do in Iceland in August

There are a ton of things to do in Iceland, but here's a breakdown of the best things in August.

Explore the Golden Circle

Taking a trip around the Golden Circle is a must-do in Iceland, and August is a great time to visit. This sightseeing tour covers 186 miles, stopping at three breathtaking natural sites. First, you'll visit Thingvellir National Park, a scenic location renowned for hiking adventures, home to the awe-inspiring continental rift between North America and Eurasia. 

Visit Landmannalaugar

Furthermore, consider dropping by Landmannalaugar, a geothermal wonderland known for its multicolored mountains and beautiful rhyolite formations.

Visit the Jökulsárlón Glacier Lagoon

One of the most magical places to visit in Iceland is Jökulsárlón Glacier Lagoon. This large glacial lake, located south of Vatnajokull (Europe's largest glacier), is filled with blue icebergs that have calved off the giant glacier. August is a perfect time to visit as the lagoon's surface is often dotted with graceful seals, and you may even spot puffins along the shore. 

Experience the Midnight Sun

August provides the last opportunity to witness the beautiful phenomenon known as the Midnight Sun in Iceland. The extended summer days, with the sun setting around 10 pm at the beginning of the month and 8 pm towards the end, offer a unique display of colorful sky illuminated by the lingering sun.

Can you see the Northern Light in August

The Northern Lights, also known as the Aurora Borealis, are generally more difficult to observe during the summer months, including August. This is because natural light conditions in summer, especially in high-latitude regions where the Northern Lights are most often observed, make it difficult to see the aurora.

Best months to see the Northern Light

The ideal time to see the Northern Lights is when the nights are long and dark, typically from September to March. At this time, your chances of seeing the Northern lights are higher due to longer stretches of darkness and clear night skies. 

For the best chance to see the lights, keep a close eye on the Icelandic Meteorological Office's Northern Lights Forecast. Also consider visiting hidden gems in the highlands, the F-roads, for a more isolated, and potentially rewarding experience.

For more information, read our detailed guide to the best places and times to see the Northern Lights.

Here are some answers to some common questions while planning your trip.

What to wear in Iceland in August

When packing for Iceland in August, remember that the weather can be quite unpredictable. As a key tip gleaned from personal recommendations, remember to pack a base layer or thermal shirt, and don't forget your waterproof and windproof pants - especially smart for those chillier encounters. 

Lighter layers are great for warmer days, but also remember a few warmer layers like a fleece or wool sweater, even consider some Icelandic wool sweaters. These are perfect for when the temperature drops in the evenings. Waterproof hiking shoes, preferably durable water-proof ones, are essential for any outdoor activities, just like your favorite pair of pants. 

A hat and gloves may come in handy, especially in the evening or while on those enthralling whale-watching tours. For a touch of comfort and flexing, leggings are a must-have, as is a swimsuit for that thrilling snorkeling adventure in the many geothermal springs, or a relaxing dip in numerous geothermal pools.

Do you need to book ahead in August

Absolutely! August is a part of Iceland's high season, meaning it attracts a large number of tourists. Accommodations, car rentals, and popular tours can often be fully booked months in advance. 

To make sure you have the best choices and avoid any disappointments, it's highly recommended that you book your flights, accommodations, and tours as early as possible. A booking of up to six months is not unheard of for peace of mind and guaranteed reservations during your trip.

Is it crowded in August?

Yes, August is one of the busiest months in Iceland as far as tourism is concerned. Many travelers from around the world prefer this period because of the warm weather, the long days of the midnight sun, and an array of exciting outdoor activities. 

This results in crowded tourist attractions, particularly in well-known spots such as Reykjavík, the Golden Circle, and the South Coast. However, there are many ways to escape the crowds by heading to off-the-beaten-track locations or exploring during off-peak hours.
