Iceland Weather - Temperature & Climate by Month
Whether you plan to visit Iceland in the summer or winter understanding Iceland’s weather by month is essential for making the most of your visit.
Despite being located just below the Artic Circle and being home to the northernmost capital in the world, Iceland experiences a surprisingly moderate climate thanks to the warming effects of the Gulf Stream. However, conditions can vary significantly from month to month, with swift changes in temperature and precipitation and daylight hours going to extremes in the summer and winter months. Whether you're planning a summer road trip under the midnight sun or chasing the northern lights in winter, understanding Iceland’s weather by month is essential for making the most of your visit. This guide breaks down Iceland's temperature and climate to help you prepare for any adventure.
What’s the Weather Like in Iceland?
The weather in Iceland is famously unpredictable, often shifting from sunshine to snow or rain within the same hour. Winters are cold but not extreme, especially in coastal areas, with temperatures typically ranging from -1°C to 4°C (30°F to 39°F). Summers are cool and refreshing, averaging 10°C to 15°C (50°F to 59°F), with long daylight hours. Wind is a constant presence throughout the year, sometimes reaching gale force, especially in exposed areas. Rain and snow are common, and although it is rare, snow sometimes falls in middle of summer in the highlands, so travelers should always be prepared for rapidly changing conditions, regardless of the season.
An Overview of Iceland’s Climate
Iceland’s climate is classified as subarctic and oceanic, characterized by cool summers, mild winters, and frequent shifts in weather. Influenced by the North Atlantic Current, the coastal regions stay relatively temperate, not getting extremely cold nor extremely hot, while the interior can be much colder and more extreme. Precipitation is common throughout the year, often in the form of rain, snow, or sleet, and strong winds are a regular feature of the landscape.
Typical Weather Conditions
Typical weather conditions in Iceland are highly variable and often unpredictable. It’s common to experience sunshine, rain, wind, and even snow—all in a single day. That said, the country tends to be cool year-round, with the warmest temperatures only reaching 10°C to 15°C (50°F to 59°F) on average. But wind is a constant factor, especially in open areas, and storms can roll in quickly. Due to these rapid changes, dressing in layers and being prepared for all types of weather is essential when traveling in Iceland.
How Iceland’s Weather Can Affect Your Trip
Iceland’s unpredictable weather can have a significant impact on your travel plans. Sudden changes in conditions—such as strong winds, heavy rain, or snowstorms—can lead to road closures, delayed flights, and limited access to popular sites like waterfalls, glaciers, or highland areas. Outdoor activities such as hiking, whale watching, or northern lights tours may be canceled or rescheduled at short notice. Travelers should always monitor weather forecasts, stay flexible with their itinerary, and prioritize safety when exploring. Being well-prepared for changing weather ensures a smoother and more enjoyable Icelandic adventure.

Iceland Regional Climate Variations
Iceland may be a small island, but its climate varies across different regions. This is largely due to the island’s unique geography, the influence of ocean currents, and its proximity to the Arctic Circle.
In the capital area around Reykjavík, the climate is relatively mild by Icelandic standards. Winters are cold but not extreme, and summers are cool and often cloudy.
In the south, the weather tends to be wetter and warmer compared to other parts of the country. This region gets the most precipitation, making it lush and green but also prone to frequent rain and storms.
The west, including the Westfjords, is characterized by colder winters and heavier snowfall, particularly in the fjord areas. The terrain here makes the weather more variable and often severe, especially during winter months. Some areas can be inaccessible for extended periods due to snow or landslides.
In the north, around towns like Akureyri and Húsavík, the climate is colder and drier than the south. Winters tend to be snowier and more prolonged, while summers are often sunnier and clearer. This region is generally more stable, but heavy snow and icy roads are common in winter.
The east features a mix of climates, with relatively dry and calm conditions along the coast—especially in towns like Egilsstaðir—due to shelter from the surrounding mountains. However, the weather can be quite changeable, particularly further inland and in higher elevations, where snow and ice persist well into spring.
In contrast, the highlands—Iceland’s interior—are known for their extreme weather conditions. This region is uninhabited, and accessibility is limited to the summer months when the F-roads open. Even then, sudden weather changes are common, and travelers must be well-prepared.
Each region offers unique experiences, but it’s essential to understand the local climate before planning your itinerary.
Unpredictable Weather Conditions in Iceland
One of the most common sayings in Iceland is: “If you don’t like the weather, just wait 5 minutes.” This reflects the highly unpredictable nature of Icelandic weather, where sunshine can quickly turn into snow or sleet, and calm skies can give way to strong winds.
Weather conditions can shift dramatically throughout the day, especially in the spring and fall. For visitors, this means dressing in layers, always being prepared for rain or wind, and frequently checking weather forecasts before heading out.
Storms & Wind Conditions
Wind is a major factor in Iceland’s weather and should never be underestimated. Strong gusts are common, especially in exposed areas like mountain passes or coastal roads. These winds can be powerful enough to damage car doors or make driving hazardous.
Storms, particularly in the winter months, can bring hurricane-force winds. When such storms hit, it’s often recommended to stay indoors and avoid travel. Always consult local weather alerts and road safety updates before setting out.
Snowfall & Ice
Snowfall varies across the country, with the north and Westfjords experiencing more frequent and heavier snow than the south. Blizzards can reduce visibility to near-zero, while icy roads create dangerous driving conditions.
Icy patches are common even in seemingly safe areas, especially in the early morning or late evening. Road closures due to snow or avalanche risk are frequent in winter, especially in the highlands and rural regions. Always check road conditions before and during your journey.
Sandstorms & Ash Storms
Though less well-known than snowstorms, sandstorms and ash storms can be equally dangerous in certain parts of Iceland. In the south, particularly near the black sand deserts and volcanic plains, high winds can lift sand or volcanic ash, reducing visibility and causing damage to vehicles.
These storms can happen suddenly and without much warning. For a deeper look at this phenomenon and how to protect your vehicle, read more on how sandstorms in Iceland are unpredictable.
Daylight Hours & Darkness
While not technically a weather condition, the extreme changes in daylight throughout the year are something many tourists overlook and can be quite jarring.
In summer, especially around the summer solstice in June, Iceland experiences nearly 24 hours of daylight, a phenomenon known as the Midnight Sun. This can be disorienting for those not used to constant light and may affect sleep patterns. We recommend traveling with a number of sleep masks so that you always have a clean one on hand.
In winter, however, daylight hours are extremely limited, especially in the north. In December, Reykjavík sees only about 4–5 hours of daylight, while parts of the north may have even less. This lack of light can impact visibility during travel and limit the time available for outdoor activities.
Travelers should plan their days carefully during the winter months to make the most of the available daylight and avoid driving in the dark, particularly on unfamiliar or icy roads.
Packing for Iceland in Any Season
Packing for Iceland requires more than just checking the forecast, it means preparing for every type of weather, regardless of the season. From sudden rain showers and strong winds to sunshine, snow, or sleet, Iceland's climate is famously unpredictable. The key? Layering and packing versatile, weatherproof gear.
Whether you're traveling in summer or winter, you’ll want to include essentials like a waterproof outer shell, thermal layers, sturdy hiking boots, and accessories like hats, gloves, and a buff/gaiter or scarf. In summer, don’t forget sunscreen, sunglasses and a sleep mask (thanks to nearly 24-hour daylight). In winter, crampons and windproof gear are essential.
So, What is the Best Time to Visit Iceland?
The best time to visit Iceland really depends on what you want to experience. From dramatic landscapes and vibrant wildlife to cultural events and natural wonders, Iceland has something unique to offer in every season.
Whether you're planning a summer road trip, a winter aurora hunt, or a quiet escape in the off-season, here are some considerations to help you choose the ideal time:
For Hiking & Outdoor Adventures
If your goal is to hike Iceland’s incredible landscapes and explore places like Landmannalaugar or the Laugavegur Trail, summer (June to August) is when you will want to visit. This is when the F-roads open, giving access to Iceland’s remote highlands and interior routes that are otherwise impassable due to snow and ice. Trails are clearer, river crossings are more manageable, and long daylight hours let you make the most of every day.
For a Camping Trip Around Iceland
Camping is one of the best ways to truly immerse yourself in Iceland’s natural beauty. The months around summer (late May to early September) are ideal, with open campsites, milder weather, and endless daylight. Many travelers choose to road trip around the Ring Road or venture into the Westfjords and highlands with a 4x4.

For Birds & Wildlife Watching
Iceland is a haven for birdwatchers and wildlife enthusiasts, especially from May to August. This is the best time to spot puffins, Arctic terns, and many migratory species along the cliffs and coastal areas. You’ll also have a chance to see seals, reindeer (mostly in the East), and even whales during summer boat tours from towns like Húsavík and Akureyri.
For Festival & Cultural Events
If you're drawn to culture, Iceland offers year-round festivals that showcase music, art, and tradition. In summer, don’t miss events like Reykjavík’s Secret Solstice Festival, National Day (June 17) and Pride in early August. Meanwhile, winter brings cozy indoor festivals like Iceland Airwaves in November or the Winter Lights Festival in February, celebrating creativity and light during the darkest months.
For Northern Lights Hunting
The magical Aurora Borealis appear in Iceland from late September to mid-April, with the darkest months (October to March) providing the best visibility. Clear skies, low light pollution, and solar activity all play a role so patience and planning are key.

Cheapest Time to Travel in Iceland
For budget-conscious travelers, late fall (October–November) and early spring (March–April), are usually the most affordable times to visit. Flights and accommodations tend to be cheaper, and popular sites are far less crowded.
Keep in mind, though, that weather during these months can be especially unpredictable, and some attractions (like the highlands which can only be accessed by F-roads) may still be inaccessible. Still, for those willing to embrace the elements, these off-peak times offer a quieter, more intimate Icelandic experience.
