May’s closing days bring a noticeable shift in Iceland’s climate. Longer daylight hours and milder temperatures begin to dominate, creating a transitional period between the cooler spring and the warmer summer months. This period typically experiences average temperatures ranging from 4C (39F) to 10C (50F), though variations can occur depending on location and specific weather patterns. Coastal regions often encounter cooler temperatures and stronger winds, while inland areas may experience slightly warmer, drier conditions.
The increasing daylight and milder weather of this time offer significant advantages for travelers. Roads previously inaccessible due to winter conditions often open, expanding exploration possibilities. Hiking trails become more accessible, unveiling the country’s natural beauty with budding flora and active fauna. The extended daylight hours provide ample time for sightseeing and other outdoor activities. This specific timeframe offers a balance between comfortable temperatures and fewer crowds compared to the peak summer season.
