The average temperature hovers around 10-12°C, which is comfortable for outdoor activities like birdwatching. This is also when the puffins are nesting, offering a prime opportunity to see these iconic birds up close. The ferry service from Dalvík also operates more frequently in the summer, providing more convenient access to the island.For birdwatchers, July is particularly good as it's the peak nesting season for most seabirds, including the Arctic Tern, which Grimsey is famous for. The cliffs and coastal areas are filled with life, and the midnight sun allows for extended viewing opportunities.Travellers interested in experiencing the Arctic Circle will find the summer months offer the best chance for a pleasant and accessible visit.
