Understanding Iceland's Seasons and Weather Patterns

Straddling the line between the North Atlantic and Arctic Ocean, Iceland’s weather is a heady cocktail of influences. It’s an exciting medley of shifting patterns, resulting from its prime location, the warming Gulf Stream, and its unique geography. The country’s maritime climate is characterized by rapid changes, making the weather forecast a mere suggestion rather than a certainty.

Whether you’re soaking in the geothermal pools of the Blue Lagoon or exploring the geysers of the Golden Circle, understanding the country’s weather patterns can enhance your experience. The average temperature hovers around 41 F (5 C), but it can vary significantly across the island. Winters in Reykjavik are usually around 33-35 F (1-2 C), and summers hover at about 54 F (12 C). But if you venture north, brace yourself for colder climes, with winters at about 32 F (0 C) and summers around 52 F (11 C). And don’t be surprised if you stumble upon snow, strong winds, and heavy rain when you explore the highland areas during summer.

Let us examine these weather nuances further in the day forecast.

The Influence of the Gulf Stream on Iceland's Climate

The Gulf Stream, a warm ocean current originating from the Caribbean, plays a starring role in Iceland’s weather drama. By bringing warm water from the equator, it has a moderating effect on the country’s climate, making Iceland’s weather milder than what you might expect for its latitude.

This constant flow of warmth doesn’t just keep the chill at bay; it also adds an element of unpredictability to Iceland’s weather. The Gulf Stream ushers in a generous amount of rain showers, especially in the south. This mix of warm Atlantic air and cold Arctic air can cause the weather to change rapidly and dramatically.

Therefore, if you experience sunny weather one moment and sudden light rain the next, the Gulf Stream is responsible.

Variability of Weather Across the Island

If you’re looking for consistency, Iceland’s weather might not be your cup of tea. It can vary greatly depending on where you are. For instance, the southern part of the country experiences more rain, thanks to the influence of the Gulf Stream.

Meanwhile, the coastal areas are usually milder, with temperatures ranging from 6°C to 3°C, while the inland areas can get much colder, dropping to bone-chilling lows of up to -30°C. The coastal regions also receive more rain than their inland counterparts.

The relentless wind chill is a significant factor in Iceland’s weather, making it feel much colder than what the thermometer might suggest. And as for snowfall, it’s a fleeting affair in most parts, except in North Iceland or higher altitudes where snow tends to linger.

Seasonal Shifts and Their Impact on Daylight

In Iceland, the daylight hours dance to the tune of the seasons. Its high latitude near the Arctic Circle gives birth to long daylight hours in the summer, with nights that barely darken. This period is known as the Midnight Sun.

During the summer months of June and July, the country bathes in 20 to 22 hours of daylight. The sun barely dips below the horizon, creating a surreal spectacle of endless twilight. Contrast this with the short days of winter, where daylight is a precious commodity, lasting just over four hours.

While Iceland doesn’t experience a full Polar Night, the sun barely peeks above the horizon, giving rise to long nights and a heightened chance of catching the Northern Lights.

A Month-by-Month Guide to Iceland's Weather

Having broadly covered Iceland’s weather, we shall now discuss what each month presents. From the chilly embrace of January to the mild caress of July, each month in Iceland offers a unique weather experience.

October takes the crown as the wettest month, so keep that raincoat handy if you’re planning a visit then. As for daylight, summer is when Iceland truly shines. Around June and July, the country enjoys 20 to 22 hours of daylight each day, a stark contrast to the short winter days from October to March, with daylight lasting a mere 10+ hours.

January's Chill and Northern Lights

January in Iceland is a winter wonderland, with average temperatures swirling around 0°C (32°F). However, don’t let this dissuade you from visiting, as the frigid temperatures can dip to -10°C or climb to +5°C (14°F to 41°F). The country also sees an average snowfall of about 7 inches (17.8 cm).

The daylight hours in January are limited to around 4 to 7 hours on average. The long nights, however, provide a dark canvas for one of nature’s most breathtaking performances - the Northern Lights. The clear skies of winter offer the best view of this ethereal spectacle, a light show powered by electrically charged particles from the sun hitting Earth’s magnetic field.

July's Warmth and Midnight Sun

July paints a vastly different picture from January’s icy grasp. With average temperatures of around 55°F (13°C), and highs reaching up to 68°F (20°C), July is a pleasant respite from the cold.

What sets July apart is the phenomenon of the Midnight Sun, with Iceland basking in an astounding 20 to 22 hours of daylight. This extended daylight opens up a world of opportunities for outdoor activities and events, from glacier tours and hikes to festivals like the Reykjavik Art Festival and Reykjavik Pride.

Preparing for Rain and Snow: What to Pack


Packing for Iceland’s unpredictable weather can be a bit of a puzzle. Regardless of planning a winter adventure or a summer visit, preparing for diverse weather conditions is imperative.

Waterproof and wind-resistant clothing is your best friend in the Icelandic climate. Brands like Patagonia, 66 North, and Gortex offer ‘hard shell’ jackets that stand up to Iceland’s weather. For the colder months, insulated or down jackets are recommended, along with merino wool base layers and thermal undies for extra warmth. And don’t forget to pack:

  • warm gloves

  • scarves

  • hats

  • waterproof shoes

Driving in Iceland: Weather Considerations

While driving in Iceland promises stunning views at every bend, weather conditions may occasionally disrupt your travel plans. From glistening glaciers to black sand beaches, the country’s diverse landscapes can be as challenging as they are beautiful, especially during winter.

Before setting off, it would be prudent to acquaint yourself with the existing road conditions. Websites like or provide real-time road conditions, a crucial resource in a country where winter roads can get slippery or even close, especially in the North. In times of heavy rain, snowstorms, and fog, drivers should exercise caution and adjust their speed accordingly. And remember, for icy and slippery roads, studded snow tires are your best bet.

The Best Times to Visit Iceland for Ideal Weather


Selecting the optimal time to visit Iceland does not have a universal answer. The ‘ideal’ time largely depends on your weather preferences and the experiences you’re seeking. From the warm summer months to the snowy landscapes of winter, each season brings its unique charm.

Summer in Iceland, from June to August, offers mild weather and longer daylight hours, perfect for outdoor activities and exploration. Autumn, particularly late August, brings with it colorful fall landscapes, cheaper accommodations, and a chance to catch the Northern Lights.

Winter, on the other hand, offers its unique attractions. Some reasons to travel in winter include:

  • Northern Lights

  • Cheaper flights and accommodations

  • Stunning winter landscapes

  • Cozy hot springs

Winter is an excellent time to experience snowfall during a budget trip filled with these attractions.
