These Are the Best Times to Visit Iceland

Over the last decade, Iceland has become one of Europe's "it" destinations thanks to its ethereal — and highly photogenic — landscapes featuring ancient glaciers and rugged fjords.

Before you book your flight to this popular island nation, you'll want to think about everything you want to see and do on your trip because the time of year can determine what's available. Some attractions, like Iceland's famous hot springs, are open all year, while natural phenomena like the northern lights and midnight sun are best viewed during specific months. Here's a breakdown of the tourist seasons in Iceland:

• High Seasons: June to August and late December
• Shoulder Seasons: September to October and May
• Low Season: November to April, excluding holidays

Read on to learn about the best time to visit Iceland for whale watching, northern lights spotting, and more.

Best Times to Visit Iceland for Smaller Crowds

The busiest months in Iceland are June, July, and August, when most natural attractions are open and easily accessible. Iceland can stay relatively warm through the first week of October, so planning a September visit can be ideal since most crowds have thinned as children return to school. May, too, provides ample daylight for sightseeing, warmer temperatures, and fewer crowds.

The off-season between November and April is ideal for those looking to escape the hordes of tourists, as long as you don't mind the dark (by mid-winter, expect only five or six hours of daylight). Though some roads are closed, it's a glorious time to enjoy hot springs, backcountry skiing, and tours by snowmobile or jeep. You'll also have a better chance of spotting the northern lights. Tourism tends to pick up again during the holiday season, so avoid December if you're looking for a crowd-free vacation.

Best Times to Visit Iceland for Good Weather

During the summer months — July and August — the temperature in Iceland hovers around 50 to 55 degrees Fahrenheit, making it a popular time to visit. And June, with its 24 hours of daylight, sees just about as many tourists as the peak of summer. But even during this season, rain and intense wind are not uncommon. The island's fickle climate often means you can experience all four seasons in a single day.

The weather remains pleasant in September, with temperatures between 43 and 52 degrees Fahrenheit. May is similar, but if you're keen on exploring some of the more remote hills and fjords, it might not be the best time to visit, as some roads remain closed while they thaw from winter's snowy cover. For serious hikers, the best time to visit Iceland is during the summer, when all the mountain roads and famous trails are open and accessible.

Best Times to Visit Iceland for Lower Prices

Getting to Iceland can be relatively affordable, especially compared to other European destinations. Travelers from the United States and Europe frequently find flight deals — keep an eye out for sales on Icelandair and low-cost airline Play to save even more on your journey.

Accommodations, tours, attractions, and meals can be pretty pricey throughout the year, but you might be able to save money by visiting during the off-season, which is typically late fall through early spring, excluding December. Summer is usually the most crowded and expensive time to visit.

Best Time to Visit Iceland for the Northern Lights

You'll need three essential factors to see the aurora borealis: darkness, clear conditions, and a surge in solar activity. The northern lights are often elusive and can easily be marred by transient clouds. To avoid disappointment, travelers should never plan their trip to Iceland solely for the northern lights because the island's weather is too capricious (statistically, there are more clear nights in Yellowknife, Canada, for example.) The best way to optimize your chances of seeing the northern lights in Iceland is by visiting from mid-October through March, when you have extended hours of darkness, and by getting out into the countryside to reduce ambient light pollution.

Best Time to Visit Iceland for Whale Watching

According to Icelandic marine biologist Edda Elísabet Magnúsdóttir, the peak months to go whale watching in Iceland are June and July. During the summer, Reykjavík sees higher numbers of minke whales and dolphins, while orcas congregate in West Iceland along the Snaefellsnes peninsula during the first half of the year.

In northern Iceland, you'll have a wider window to enjoy visits from humpbacks, minkes, and dolphins, which ply the Atlantic from May to August; a few humpbacks even stick around until the end of the year. Blue whales pass through in the summer, too. For best results, head to the charming small town of Húsavík, where you can spot more than 20 species of whales on boat tours that leave from the harbor.

Best Time to Visit Iceland's Hot Springs

Hot springs are intrinsic to Icelandic culture for social as well as wellness benefits. Reykjavík's public pools are open year-round (and are especially invigorating during the dead of winter), but Iceland also has hundreds of hidden "hot pots" that tap directly into the geothermal activity under its lava-ridden surface.

Expert Icelandic mountaineer and cofounder of Midgard Adventure, Sigurdur Bjarni Sveinsson, offers the following advice for hot water hunters: "Check them out during September or, even better, the first half of October, when they're all still accessible by mountain road, but the crowds of tourists have significantly died down."

For travelers who want to visit the Blue Lagoon, the most famous geothermal spa, the best time to visit is during the off and shoulder seasons, when crowds are thinner.

Worst Time to Visit Iceland

Thanks to Iceland's stunning landscapes and seasonal natural phenomena, there's really no bad time to visit. Northern lights seekers flock to the country during the darker winter months, while visitors chasing more daylight opt for summer. Of course, those traveling in the spring and fall can take advantage of more moderate weather and daylight, so the best time to visit Iceland depends on what you want to see and do during your trip.

That said, the warmest months of the year are easily the worst time to visit if you're hoping to avoid the onslaught of tourists. July and August see the highest number of travelers, with big-ticket attractions like the Blue Lagoon, Golden Circle, South Coast, and Jökulsárlón being particularly overrun. If you're planning to visit during that time, consider exploring more remote corners of the island like the Westfjords or East Iceland, which have their own cache of fjords, vistas, and waterfalls that are just as impressive as the natural attractions surrounding the capital — if not more.
