Iceland Weather in May

 Temperature in May

May is considered the start of the shoulder season in Iceland. While the country is still shaking off the last signs of winter, temperatures start to rise noticeably.

– Average Temperature: 4°C to 10°C (39°F to 50°F)

– Daytime: Cool to mild, especially by Icelandic standards

– Nighttime: Chilly, but generally above freezing

In coastal cities like Reykjavik and Akureyri, May brings relatively mild weather. However, keep in mind that the temperature can vary widely depending on where you are in the country, particularly if you’re venturing into higher altitudes.

 Daylight Hours in May

One of the biggest perks of visiting Iceland in May is the dramatically increasing daylight. By the end of May, Iceland experiences almost 20 to 22 hours of daylight. This phenomenon is part of the lead-up to the famous Midnight Sun.

– Early May: About 17 hours of daylight

– Late May: Close to 21 hours of daylight

This extended daylight means more time for sightseeing, hiking, and soaking in Iceland’s breathtaking landscapes without feeling rushed.

 Wind and Rain in May

– Wind: May can still be quite windy, especially along the coast and in open areas. Windproof jackets are essential.

– Rain: Rainfall is relatively moderate, but showers can occur unexpectedly.

Always be prepared for “all four seasons” in one day—sunshine, wind, rain, and sometimes even a flurry of snow in northern regions.

 

Iceland Weather in June

 Temperature in June

June is when summer truly kicks in across Iceland. While temperatures are never tropical, they are pleasantly cool for most travelers.

– Average Temperature: 9°C to 15°C (48°F to 59°F)

– Nighttime: Cool but rarely freezing

The southern coast, where attractions like the Golden Circle, South Coast waterfalls, and Jökulsárlón Glacier Lagoon are located, tends to be slightly warmer than the north.

 Daylight Hours in June

Welcome to the world of the Midnight Sun! From mid to late June, especially around June 21st (Summer Solstice), Iceland experiences 24 hours of daylight in many parts of the country.

– Full Daylight: In Reykjavik and northwards, the sun barely sets, creating a surreal twilight that lasts all night.

This constant daylight allows for endless road trips, nighttime hiking, and extraordinary photography opportunities. It’s one of the biggest reasons why June is a popular month to visit Iceland.

 Wind and Rain in June

– Wind: While less intense compared to winter months, sudden gusts are still possible.

– Rain: June is relatively dry compared to other months, but light showers can pop up, especially in western Iceland.

Overall, June offers some of the most pleasant weather conditions of the year in Iceland.
