The Ultimate Weather Handbook for Exploring Iceland Year-Round

There are adventures in Iceland year-round, but the best time to visit depends on your interests and what activities you’re hoping to experience. Find out the pros and cons of each season for an optimal trip. Spring and Fall offer mild weather, beautiful colors, and less-crowded tour options. Winter brings snow, ice, and the chance to see the Northern Lights.

Spring

In planning a trip to Iceland, it’s essential to consider the diverse Iceland weather by month, as the island experiences various temperatures, precipitation, and daylight hours throughout the year.

In the spring, Iceland’s landscape is reborn as the snow melts, greenery blossoms, and flocks of birds return to nest. Though temperatures remain chilly, daytime highs rise to around 20 degrees Celsius. You’ll have more time to explore and experience the island with longer daylight hours. The shoulder season (April to May and September to October) also sees fewer crowds, making spring an excellent time to visit Iceland.

Summer is the liveliest season in Iceland, characterized by warm weather and many events and activities. The days are longest during the summer solstice in June, and you can experience the “midnight sun” the further north you go on the island. However, the climate is still unpredictable due to swirling competing air masses. As a result, the weather can change in the blink of an eye, meaning that some activities (like ice caving and glacier tours) might not be available.

The start of Fall is a popular time to visit Iceland as it marks the transition from summer to winter and is an ideal time for viewing the Northern Lights. The weather remains comfortable, with temperatures hovering between 16 and 20 degrees Celsius, but the daylight hours are beginning to shorten. This makes it an excellent time to take advantage of the best of both seasons – you can see the Northern Lights while enjoying a more mellow vacation.

Summer

This is Iceland’s prime season when its natural beauty is on full display. The luscious green flora of the countryside comes into bloom, and the island’s famous waterfalls and hot springs are at their most spectacular.

The days are long and bright thanks to the midnight sun phenomenon, giving you plenty of time to explore hiking trails and wilderness areas that are otherwise inaccessible during other seasons. You’ll also be able to see puffins and whales during this time.

It’s also important to remember that summer is peak tourist season, so expect crowds at the most popular attractions and activities. Be sure to book your accommodation, car rental, and tours or excursions well in advance.

If you’re looking for a more offbeat experience, visit in early March for the cultural festival of Thorrablot. In the lead-up to the vernal equinox, locals celebrate the transition from winter to spring with food and drink like hakarl (fermented shark meat) and svid (boiled sheep’s head), all washed down with Brennivin schnapps. It’s also an excellent time for photography, as the shortened daylight hours create long, golden light throughout the day. Those looking to get active can also take advantage of the warmer temperatures and explore Iceland’s mountainous landscapes by trekking on snowshoes or ice-caving. It’s worth noting, however, that some hiking trails may still be covered in lingering snow.

Fall

If you’re a nature lover, the fall season is the best time to visit Iceland. The landscape is filled with beautiful autumn colors, and the air is warm enough to enjoy hiking without wearing a heavy coat or hat. The daylight hours are also longer than in the winter, giving you more opportunities to explore Iceland’s incredible hiking trails.

Another perk of visiting in the Fall is that whales are spotted more frequently than during summer. They’re out and about feeding fish, krill, and other sea life while building their fat stores for winter. And if you’re lucky, you might even see an Arctic fox.

However, the weather can be unpredictable during this time as well. It could be bright sunshine one day and snow the next. So, it’s essential to bring a variety of clothing options and to be prepared for dramatic changes in conditions.

Check road conditions regularly if you want to visit Landmannalaugar or Thorsmork in the Fall. Due to Iceland’s unique geography, the weather can vary widely from one region to another. Following the official Icelandic Highway Authority’s Facebook page is the best way to keep up with the latest road information. They post updates from 7:00 to 22:00 every day.

Winter

The winter season runs from November through March and is Iceland’s coldest and darkest time. However, that’s not to say it isn’t still beautiful and full of fun things to do! The winter months are an ideal time to see the Northern Lights and hike or snowmobile on a glacier. Plus, you’ll be able to visit the famous Blue Lagoon during a magical twilight and enjoy the peace away from the summer crowds.

The hottest times of the year are June, July, and August. This is also peak tourist season, which means you’ll encounter many more people at all the major attractions.

Despite its popularity, Iceland is still a very safe place to visit at any time of the year. It is a very isolated country with a low crime rate, and the only thing that could cause problems is road closures from snow or ice storms.

Another bonus of visiting in the winter is that you’ll be able to soak in one of Iceland’s many natural hot springs and geothermal pools. Nothing is more relaxing than sitting in a naturally heated pool and watching the Northern Lights flicker overhead. It’s a truly unforgettable experience!
