The best time to go to Lerwick is during the summer months, from June to August, when the weather is mildest and the days are long.During this period, you'll experience the famous "simmer dim," where daylight extends late into the evening, offering more hours for exploration. Average temperatures range from 10°C to 15°C, making it comfortable for outdoor activities like coastal walks and boat trips to see wildlife. The sea is also calmer, which is ideal if you're planning to visit some of the smaller islands or enjoy a ferry journey.Couples often find this time particularly enjoyable for exploring the islands, as the longer days allow for leisurely sightseeing and enjoying the natural beauty, like the dramatic cliffs of Sumburgh Head or the archaeological site of Jarlshof. Many local events and festivals, such as the Shetland Folk Festival, also take place during the summer, providing a chance to experience the local culture.For those interested in wildlife, especially birdwatching, the summer is prime time. Seabirds like puffins and gannets are nesting on the cliffs, and boat tours offer excellent opportunities to see them up close.
