Iceland is a land of extremes, and its weather shifts more in a single day than most Canadian cities see in a week. If you are planning a trip to this volcanic island, understanding the iceland weather by month is the difference between packing the right jacket and shivering through a glacier hike. This guide breaks down every month of the year so you can choose the right season, pack with confidence and enjoy every moment of your Icelandic adventure.
Key Takeaways
- Summer (June to August) offers the warmest weather and the most daylight: Average highs reach 13C in Reykjavik with up to 21 hours of sunlight daily, making it the most popular season for sightseeing.
- Spring and autumn are shoulder seasons with fewer crowds: May and September deliver mild temperatures between 5C and 10C, lower prices and a mix of daylight and darkness that can include northern lights.
- Winter is cold but magical: December through February brings average temperatures around -1C to 2C with limited daylight, but the northern lights, ice caves and snowy landscapes create a dramatic setting.
- Layering is non-negotiable year-round: Iceland’s weather can change multiple times in a single hour, so a waterproof outer layer and thermal base layers are necessary no matter the month.
Iceland’s Climate: What Canadian Travellers Should Know
If you live in Toronto, Montreal or Vancouver, you already know cold weather. But Iceland’s climate works differently than anything you have experienced in Canada. The island sits just below the Arctic Circle at 64 degrees north latitude, yet the Gulf Stream keeps it surprisingly mild compared to northern Canadian cities at the same latitude. Reykjavik’s average winter temperature hovers around 0C, warmer than Winnipeg, Edmonton or even Ottawa in January.
The real challenge is not the cold. It is the wind. According to the Icelandic Meteorological Office, average wind speeds in coastal areas reach 15 to 25 km/h year-round, with gusts regularly exceeding 50 km/h in winter (Vedur.is, 2024). That wind chill makes a 2C day feel well below freezing. Rainfall is also frequent, with Reykjavik receiving precipitation on roughly 148 days per year (World Meteorological Organization, 2023).
The other factor that shapes your Iceland experience is daylight. In June, the sun barely sets, giving you nearly 24 hours of light. In December, you get about 4 to 5 hours of daylight. This swing is more extreme than anywhere in southern Canada and it affects everything from photography to your energy levels. If you are weighing shoulder season travel, May and September deliver a middle ground of decent daylight and fewer crowds.
Spring in Iceland (March to May)
March
March marks the slow transition from winter. Average temperatures in Reykjavik range from -2C to 3C, and snowfall is still common across the highlands. Daylight increases to roughly 12 hours by month’s end, a welcome change after the dark winter. Roads in the interior remain closed, but the Ring Road is generally passable. The northern lights are still visible early in the month before the skies brighten.
April
April is when Iceland begins to wake up. Temperatures climb to 0C to 6C, and the snow starts to melt in lower elevations. Puffins begin arriving at coastal cliffs around mid-April, which makes this a great month for birdwatchers. Daylight stretches to 16 hours by the end of the month. Rain and wind remain unpredictable, so waterproof layers are still a must. Tourism is light, meaning shorter queues at popular spots like Thingvellir and the Golden Circle.
May
May is the sweet spot for many travellers. Average temperatures range from 4C to 10C, lupins start to bloom across the landscape and daylight reaches nearly 20 hours. Most highland roads begin to open by late May, giving access to the interior for the first time since autumn. Tourist numbers are still moderate compared to summer. This is one of the best months for Icelandic wildlife, as migratory birds return and whale watching season begins off the north coast. According to the Icelandic Tourist Board, visitor numbers in May are roughly 40% lower than July (Ferdamalastofa, 2024).
Summer in Iceland (June to August)
June
June brings the midnight sun. The sun barely dips below the horizon, giving you up to 21 hours of functional daylight. Average temperatures in Reykjavik sit between 8C and 13C, with the south coast slightly warmer. This is peak hiking season, and trails like Laugavegur and Fimmvorduhals open for the year. The Golden Circle, Vik and Jokulsarlon glacier lagoon are all accessible. June is also when Approach Tours runs its Ethereal Iceland tour, a 13-day all-inclusive journey that covers the island’s highlights from Reykjavik to the glaciers of the south coast.
July
July is Iceland’s warmest month. Average highs reach 13C to 15C in Reykjavik, though sunny days can push temperatures to 20C. All highland roads (F-roads) are open, making the interior highlands accessible for 4×4 excursions. Puffin colonies are at their peak on the Westman Islands and Latrabjarg cliffs. This is also the busiest month for tourism, so popular sites can be crowded between 10 a.m. and 4 p.m. Early mornings and late evenings, still bright as midday, are the best times to explore.
August
August remains warm by Icelandic standards, with temperatures averaging 9C to 13C. The midnight sun fades gradually, and by late August, you start to see darker skies again. This is a strong month for whale watching off Husavik, where humpback whale sightings peak. Berry picking becomes possible across the countryside. The first hint of autumn colours appears in the last week. Crowds thin slightly compared to July, making it a good balance of warm weather and manageable visitor numbers.
Autumn in Iceland (September to November)
September
September is many seasoned Iceland travellers’ favourite month. Temperatures drop to 5C to 10C, the landscape erupts in red and gold and the northern lights return to Icelandic skies. Daylight is still generous at 12 to 14 hours. Crowds thin out, and accommodation prices begin to drop. Most of the Ring Road remains open, though some highland F-roads close for the season. Approach Tours offers September and October departures that take advantage of this quieter shoulder season, with autumn colours adding a dimension you will not find in summer.
October
October brings cooler temperatures between 2C and 7C, and the first dustings of snow appear on mountain peaks. The northern lights are reliably visible on clear nights, and with daylight dropping to about 10 hours, you have longer windows of darkness for viewing. Tourist numbers fall sharply, giving you a more intimate experience at the major sights. This is also when ice caves in Vatnajokull glacier begin to form, though most are not accessible until November. Wind and rain increase, particularly along the south coast.
November
November is the start of Iceland’s dark season. Average temperatures range from -1C to 4C, and daylight shrinks to about 6 to 7 hours. Snow becomes common at all elevations. The upside is outstanding northern lights viewing and the opening of crystal-blue ice caves inside glaciers. This is a quiet month for tourism, and you will find some of the lowest prices of the year for flights and hotels. Interior roads are closed, and weather conditions can disrupt travel plans, so flexibility is important.
Winter in Iceland (December to February)
December
December is Iceland’s darkest month, with only 4 to 5 hours of daylight in Reykjavik. Average temperatures hover between -1C and 3C, milder than you might expect thanks to the Gulf Stream. The capital comes alive with holiday markets and the 13 Yule Lads, Iceland’s Christmas folklore tradition. Ice caves are fully accessible, and the northern lights dance across the sky on clear nights. Road conditions can be challenging, with frequent closures on highland routes and occasional closures on sections of the Ring Road.
January
January is the coldest month, with average temperatures ranging from -3C to 2C in Reykjavik. Windstorms are common, and blizzard conditions can develop with little warning. Daylight slowly increases to 6 to 7 hours by month’s end. For Canadians accustomed to harsh winters, January’s temperatures will feel familiar, though the wind and horizontal rain are a different experience entirely. Ice cave tours and northern lights excursions are the main draws. Flights from Canada are at their cheapest.
February
February brings a gradual return of light, with 8 to 9 hours of daylight by month’s end. Temperatures remain between -2C and 3C. This is often considered the best winter month for Iceland because the days are longer than December or January while ice caves and northern lights are still prime attractions. The annual Thorrablot festival celebrates traditional Icelandic cuisine with dishes that range from adventurous to alarming. Winter storms still occur, so travel flexibility remains important.

What Is the Best Time to Visit Iceland from Canada?
The answer depends on what you want to see. For warm weather, long days and the widest range of outdoor activities, June through August is the best window. For northern lights and ice caves with manageable cold, February and March offer the strongest combination. For a balance of mild weather, fewer crowds and the chance to see the aurora, September and early October are hard to beat.
Canadian travellers should also consider flight logistics. Direct flights from Toronto to Reykjavik run year-round on Icelandair, with seasonal service from Montreal and Vancouver. Flight times average 5 to 6 hours, making Iceland closer to eastern Canada than many Caribbean destinations. According to Icelandair’s route data, the Toronto to Reykjavik route operates daily in summer and 4 to 5 times weekly in winter (Icelandair, 2024).
For travellers who want everything handled, from flights and hotels to meals and excursions, Approach Tours’ Ethereal Iceland tour runs in both spring and autumn. The 13-day itinerary covers the Golden Circle, the south coast glaciers, Vatnajokull National Park and Reykjavik, with all 34 meals included, private airport transfers from your home city and a dedicated Group Guru guiding you the entire way. At $13,995 CAD per person, the all-inclusive price means no hidden costs or surprise fees.
How Should You Pack for Iceland?
Packing for Iceland is about layers, not bulk. The weather can shift from sunshine to sideways rain within minutes, so your clothing system needs to handle rapid changes. Here is what works:
- Base layer: Merino wool or synthetic thermal tops and bottoms. Avoid cotton, which holds moisture and chills you fast.
- Mid layer: A fleece or down jacket for insulation. In summer, a lighter fleece works. In winter, opt for a heavier down layer.
- Outer layer: A waterproof and windproof shell jacket is the single most important item. Gore-Tex or similar breathable waterproof fabric is worth the investment.
- Bottoms: Waterproof hiking pants over thermal leggings in colder months. Quick-dry hiking pants work for summer.
- Footwear: Waterproof hiking boots with ankle support. You will walk on uneven lava fields, wet trails and icy paths depending on the season.
- Accessories: A warm hat, neck gaiter, waterproof gloves and sunglasses (the glare off glaciers is intense year-round).
Canadian travellers often make the mistake of over-packing heavy winter gear for summer visits. A temperature of 13C with wind does not require a parka, but it does require a windproof shell and a warm mid-layer. Think Vancouver rain gear, not Winnipeg blizzard gear.

Can You See the Northern Lights in Iceland Year-Round?
No. The northern lights require dark skies, which means they are only visible from roughly September through March. During Iceland’s summer months, the midnight sun keeps the sky too bright for aurora viewing. The strongest northern lights activity typically occurs between October and February, when nights are longest and geomagnetic activity peaks.
For Canadian travellers, this is a familiar concept. The aurora borealis is visible from many parts of Canada, but Iceland’s location near the auroral zone means displays are often more intense and more frequent. The Icelandic Meteorological Office provides a daily aurora forecast (Vedur.is) that rates cloud cover and geomagnetic activity on a 0-9 scale, helping you plan your viewing nights.
If the northern lights are your primary reason for visiting, September or October offers the best mix of dark skies, mild temperatures and accessible roads. You will not be locked in by winter storms, and the autumn landscape adds colour to your photos even when the aurora does not appear.
How Does Iceland Compare to Canadian Winter?
Canadian travellers are often surprised by how mild Iceland feels compared to expectations. Here is a side-by-side comparison of January averages:
| City | Avg. January High (C) | Avg. January Low (C) |
|---|---|---|
| Reykjavik, Iceland | 2 | -3 |
| Toronto, Canada | -1 | -7 |
| Montreal, Canada | -5 | -14 |
| Calgary, Canada | -1 | -13 |
| Vancouver, Canada | 7 | 1 |
| Ottawa, Canada | -6 | -15 |
The numbers tell the story. Reykjavik in January is warmer than Montreal, Ottawa and Calgary. The difference is wind and precipitation. Iceland’s coastal winds make the felt temperature lower than the thermometer suggests, and rain or sleet can occur any day of the year. But if you can handle a Canadian winter, Iceland’s cold will not faze you.
Frequently Asked Questions
What is the warmest month in Iceland?
July is the warmest month in Iceland. Average temperatures in Reykjavik reach 13C to 15C, with occasional days hitting 20C. The south coast and sheltered valleys in the north can be slightly warmer. July also offers nearly 24 hours of daylight thanks to the midnight sun.
Is Iceland expensive for Canadian travellers?
Iceland ranks among the most expensive countries in Europe. Meals at restaurants average $30 to $50 CAD per person, and hotel rooms in Reykjavik start around $200 CAD per night in summer. An all-inclusive guided tour can offset these costs by bundling flights, meals, hotels and excursions into a single price, removing the guesswork from budgeting.
Do I need a visa to visit Iceland from Canada?
No. Canadian passport holders can enter Iceland without a visa for stays up to 90 days within a 180-day period. Iceland is part of the Schengen Area, so your entry counts toward the overall Schengen limit if you are visiting multiple European countries.
What is the rainiest month in Iceland?
October and January tend to be the wettest months in Reykjavik, with average rainfall around 80-90 mm. However, precipitation is spread throughout the year and rain can fall in any month. The south coast receives more rainfall than the north, with Vik averaging roughly twice the precipitation of Akureyri.
Can I drive the Ring Road in winter?
The Ring Road (Route 1) is generally open year-round, but sections can close temporarily due to storms, heavy snow or ice. Winter driving in Iceland requires studded tires or chains, and conditions change rapidly. Many travellers prefer guided tours in winter to avoid the stress of driving in unpredictable conditions. Real-time road conditions are available at Road.is.
Plan Your Iceland Trip with Confidence
Iceland’s weather is part of its charm. The same forces that create the northern lights, the glaciers and the geothermal hot springs also make the weather wonderfully unpredictable. Now that you know what to expect month by month, you can choose the season that matches your travel goals, pack the right gear and focus on the experience instead of the forecast.
Whether you are drawn to the midnight sun in June, the autumn colours and aurora in September or the ice caves of February, Iceland rewards travellers who come prepared. And for Canadian retirees who want every detail handled, from the flight out of Toronto to the farewell dinner in Reykjavik, Approach Tours’ Ethereal Iceland experience is designed to let you enjoy the adventure without the logistics.
