The best time to go to Sachs Harbour depends on whether you're interested in wildlife viewing or experiencing the midnight sun.
For those eager to spot muskoxen, caribou, and various migratory birds, late spring and early summer, from late May to early July, are ideal. The ice on the Beaufort Sea begins to break up, and wildlife is more active and visible along the coast and tundra. This period also offers long daylight hours, often with the midnight sun, making it superb for extended exploration.
If seeing the midnight sun is your primary goal, plan your trip between mid-June and early July. During this time, the sun never fully sets, providing a great experience of perpetual daylight. This is also a good time for fishing and enjoying boat trips on the open waters.
