What to Expect: Iceland's Weather in May

May is an awesome time to visit Iceland. As spring kicks in, the country starts to come alive with blooming flowers and longer days, getting you ready for summer. Even though average temperatures range from 4°C to 10°C (39°F to 50°F), the weather can still be a bit unpredictable, giving you that true Icelandic adventure feel.

In this guide, we’ll explain what to expect weather-wise when visiting Iceland in May. We’ll also discuss what to pack and highlight some great activities for this time of year.

Key Takeaways

  • May in Iceland brings a lovely spring thaw with average temperatures between 4°C and 10°C (39°F to 50°F).
  • Pack layered clothing, a waterproof jacket, a hat, and gloves to stay comfy no matter the weather.
  • May is perfect for things like whale watching, exploring Þingvellir National Park, and hiking on awesome hiking trails. Since road conditions can change, especially on F-roads (mountain roads), it’s smart to plan and book ahead.
  • Knowing the chance of rain and dealing with windy conditions in May is important for a fun and safe trip, as Icelandic low-pressure systems can bring sudden weather changes.

Understanding Iceland’s Weather in May

May is right in the middle of spring in Iceland, a time when the country moves from winter’s chill to the warmth of summer. The spring thaw starts, and melting snow turns the landscape green with blooming flowers, especially lovely lupines. But don’t get too comfortable—Icelandic low-pressure systems can still mix things up with rain, sunshine, and sometimes windy conditions.

Even with the variable weather, May is a fantastic time to visit. Long daylight hours—up to 18-20 hours by the end of the month—give you plenty of time to explore and enjoy outdoor activities. While the Northern Lights are harder to see because of all the daylight, the bright days offer their own kind of magic.

What is The Average Temperature in May in Iceland?

In May, average temperatures in Reykjavik usually range from 4°C to 10°C (39°F to 50°F). Akureyri, up north, can be a bit cooler, especially in the evenings. Coastal areas enjoy milder weather, while inland and higher-altitude regions might still have some snow in the Highlands.

Remember, road conditions can vary a lot across the country. Most roads are clear and easy to drive on, but some F-roads (mountain roads) might still be closed because of snow and ice. Always check the latest road conditions before you set out.

How Much Does It Rain in May in Iceland?

Rainfall in May can vary, with Reykjavik getting about 40 mm (1.57 inches) of rain spread over around 7 rainy days. While May has less snow compared to winter, mild spring showers are common, especially in the southern and western parts. This mix of rain and sunshine is part of what makes Iceland’s weather so unique.

Rain Patterns in May by Region

Rainfall across Iceland in May depends on where you are. The coastal weather brings more rain to the west and south coasts, while the north stays relatively drier but still cool. The Snaefellsnes Peninsula, known for its beautiful landscapes, also gets mixed rain levels thanks to its exposure to Icelandic low-pressure systems.

The Weather in Different Regions of Iceland in May

Just like in April, the weather in May can change depending on where you are in Iceland. Knowing what to expect in different regions helps you plan your days and make sure you’re ready for anything.

Reykjavik Weather in May

In Reykjavik, May temperatures usually range between 4°C and 10°C (39°F to 50°F). With long daylight hours, there’s plenty of time to explore the city’s attractions. It can still get pretty windy and rainy, though, so it’s always smart to bring a waterproof jacket just in case.

South Iceland Weather in May

As you head south from Reykjavik, it gets a bit warmer as spring settles in. Expect some light rain, but nothing too heavy. It’s a great time to check out spots like Gullfoss Waterfall and Þingvellir National Park, and you might even catch a glimpse of puffins along the coast, as it's nesting season.

North Iceland Weather in May

Up north, including Akureyri, it’s still cooler in May compared to the south. Temperatures are lower, but you won’t see as much rain. If you head up to the higher elevations, there’s even some lingering snow. Akureyri is also a perfect base for whale-watching tours, where you can spot humpbacks and minke whales.

The Central Highlands in May

The Central Highlands are mostly off-limits in May because of snow and icy roads. Some lower areas might start to thaw, but it’s still best to double-check road conditions if you’re thinking of heading that way.
