From April 20 the sun doesn&rsquo;t set for a full five months. The average temperature is between -12C (10F) and -15C (5F). For summer tours, July and August is the best time for wildlife viewing and flora. This is the height of the cruise season and a great time for hiking and trekking. The average temperature is 5C (41F) but it can drop below zero.
