The weather in Iceland is so unique that it deserves special mention. Iceland is one of the few countries where you can experience all the seasons in one day. It changes so quickly that Icelanders even joke about it: "Don't like the weather? Just wait 5 minutes!”
The most distinct element of Icelandic weather is undoubtedly the wind. The fact that the Icelandic language has 156 words to describe it says something about its importance. From logn (calm wind) and gola (gentle breeze) to rok (gale) and fárviðri (storm), Icelandic wind is truly something to experience! Learn more about Iceland's weather nuances, seasons, and monthly temperatures in our detailed overview.
Climate and Temperature in Iceland

The climate in Iceland is divided into two main types: a milder oceanic near the coast and a colder tundra-like climate in the highlands. For a country so close to the Arctic Circle, Iceland’s weather is surprisingly moderate. This is because of warm ocean currents, like the North Atlantic Currents, which heat up the air.
In summer, daytime temperatures average around 11°C (52°F), and the highest reach up to 15°C (59°F) on sunny days. Winters are colder, with average daytime temperatures around 0°C (32°F) and the coldest days dropping to the lowest of -10°C (14°F). Yearly averages sit between 0°C and 4°C (32–39°F). The weather changes a lot between seasons, keeping tourists and locals guessing year-round.
Iceland Seasons Overview
Iceland is a land of extremes, and seasons reflect its unique character. While there are technically four seasons, spring and autumn often seem like extensions of the two main periods due to the ever-changing weather. Summer (late May to early September) is the high season for travel, with nearly 24 hours of daylight. Winter (late November to early March) sees plenty of snowfall, and strong winds often make the actual temperature feel much colder.
Rain is common year-round but peaks in October. For the best combination of weather, daylight, and activities, late May to mid-September is usually the best time to visit Iceland. Keep in mind Iceland’s seasons are defined as much by wind and rain as by temperature.

Local weather is full of surprises, but it’s rarely extremely cold or hot. Iceland winter temperature averages -2 to 3°C (28-37°F), with frequent snow storms and ice-covered roads. As spring arrives, temperatures climb to 1-7°C (34-45°F), though the wind often picks up. Summer is the warmest time in Iceland, when the thermometers reach 7-14°C (45-57°F), with long and bright days, but quick rain showers are common. Autumn cools it down again, with highs of 11°C (52°F) dropping to 6°C (43°F) as storms become more frequent. Rain peaks in October and March, while January and February bring the heaviest snowfall of all months in Iceland.
Iceland Weather in Summer - The Season Not to Miss
From late May to August, Iceland’s summer temperatures average around 10°C (50°F), but the wind often makes it feel about 10 degrees cooler. On the hottest days, it can reach even 20°C (68°F), though that’s less common. The summer weather is unpredictable, with drizzle, sun, and wind often switching throughout the day. On average, there are 10-12 days of rain each month, but it’s usually light and doesn’t last all day. Iceland in summer is a unique experience, with nearly 21 hours of daylight thanks to the Midnight Sun. Until mid-July, it barely gets dark, perfect for exploring non-stop.
Iceland Weather in the Fall - Vibrant and Quiet
Traditionally, Icelanders only recognize summer and winter, with September seen as late summer and November as early winter. Internationally, autumn in Iceland is considered to be from September to November. This midseason marks significant changes, as the weather influence for the Northern Lights makes a big difference as Iceland aurora season begins and nights get longer. Over the months, daytime temperatures quickly drop to 5°C (41°F) in October and 0°C (34°F) in November. Rain and wind storms become more frequent, with around 13 rainy days each month. You may expect the first snow in October, especially in northern regions and higher elevations.
Strong winds and icy conditions are common in Iceland in winter, with the landscape shifting between pristine white and muddy patches. Average winter temperatures in Iceland range from -2°C (28°F) to 3°C (37°F), though the biting wind makes it feel much colder. The Westfjords and highlands often experience the coldest climate, frequently below -5°C (23°F). During the Iceland snow season, the island's glaciers freeze, creating stable ice caves for exploring. Higher elevations and northern areas see more consistent snow, while milder regions may have slush or rain. Additionally, the aurora borealis become the most popular weather phenomenon to see because of the long nights.
Iceland Weather in Spring - The Season of Contrasts
Spring in Iceland, from March to May, is a midseason of dramatic transitions. March often feels like winter, with average daytime temperatures around 1°C (33°F), frequent snow, and icy paths, especially in the north. Wildlife returns to life, with puffins in Iceland starting to breed and live their birdly lives on the island’s shores in April. By May, average daytime temperatures rise to 7°C (45°F), bringing more sunshine and greener landscapes. Spring weather remains unpredictable, with wet, windy days alternating with clear, sunny periods. Daylight increases dramatically, from 10 hours in March to 20 hours in May, offering plenty of time for exploration.
Weather in Iceland by Month
