Best time to visit Iceland

July and August, which are the hottest months in Iceland, have traditionally been the most preferred months for tourists to visit the country. And because there is continuous daylight in June, there are almost as many tourists as there are during the height of summer. However during this time of year, poor weather like heavy rain and strong winds may and does occur. Due to the unpredictable climate of the island, it is not uncommon for a single day to have elements of all four seasons.

Considering that Iceland's climate may maintain a comfortable temperature far into the first week of October, traveling there in September may be the best option. May also features more hours of daylight, making it ideal for outdoor excursions, and milder temperatures. However, this may not be the greatest time to visit if you are interested in visiting some of the more distant hills and fjords, since some roads are still blocked as they thaw from the snowy cover that they had over them over the winter.

The greatest time of year to go hiking in Iceland is during the summer, as this is the only season in which all of the mountain roads are passable and the majority of the country's most well-known paths are available.

When is the best time to see whales in Iceland?

The months of June and July are ideal for whale watching in Iceland. Northern Iceland has a longer season for seeing humpbacks, minkes, and dolphins, which cruise the Atlantic from May to August; some few humpbacks even stay until the end of the year. Blue whales also travel through in the summer.

Minke whales and dolphins can be seen near Reykjavik during the summer months, while orcas concentrate in West Iceland around the Snaefellsnes peninsula in the first part of the year.

When is the best time to visit the hot springs?

Hot water baths in Iceland are an important part of the Icelandic culture, providing both social and wellness advantages. The public pools in Reykjavik are available all year. Visit them in September or the first half of October, while they're still still reachable by mountain road but the tourist numbers have greatly decreased.

When visiting the Blue Lagoon, the world's most well-known geothermal spa, visitors will find less crowds by going in the off-seasons.
