1. Summer days are deliriously endless
In Aulavik National Park, way up on Banks Island, paddlers on the Thomsen River enjoy a “day” that lasts 2,500 hours. Up there, the sun rises for the summer on April 30 and won’t set again until August 13, three-and-a-half months later. Even in more southerly communities such as Fort Simpson (pictured above), there is no true darkness from May to July.
2. The sun does loop-de-loops in the sky
Though our summer sun never goes down, it’s not like it stands still in the sky. Instead, it rolls around the heavens in an oblique loop, reaching its zenith at midday and grazing the horizon at midnight, over and over and over. It’s seriously mind-blowing to behold.
3. You might sunburn the inside of your nostrils
Bring your sunscreen. Because of our low-angle sun, you’re more likely to get a burn when you’re standing up than if you’re stretched out flat on a beach. And watch out for UV reflecting off our clear, pure water. Plenty of hapless travellers have lathered their foreheads with SPF 50 only to end up with a wicked burn on the underside of their nose.
4. For shutterbugs, every moment is the 'golden hour'
Photographers go crazy for the midnight sun because it provides the magical dusk-and-dawn light that gives pictures a radiant glow. In the Northwest Territories, the coveted “photographic golden hour” lasts for months on end.
5. For some people, sleeping can be tough
If you’ll be camping up here, you might want to bring a sleep-mask. Why? Daylight stimulates the photoreceptive ganglia of your eyes, which tells your pineal gland to stop making melatonin. Melatonin is what makes you feel drowsy and lowers your body temperature in preparation for sleep. Without it – hello, insomnia. (Luckily, Northwest Territories hotel rooms are usually equipped with “blackout blinds” to keep the 2 a.m. sunbeams from blazing into your room.)
6. But for animals, sleeplessness is no problem
Some animals in the Northwest Territories are specially adapted to endless daylight. Caribou have a set of genes that spare them from needing to sleep on a regular 24-hour cycle. Instead, they stay active throughout the bright Arctic summer, napping only sporadically.
7. At the Arctic Circle you can watch the sun not set
The Northwest Territories is bisected by the Arctic Circle. That’s the imaginary line where, on June 21 – the summer solstice – the sun doesn’t drop below the horizon. The farther north you go from the Arctic Circle, the longer the sun stays up. At the northernmost point on Earth, the North Pole, the sun is up for six months straight.
8. You can get there on Canada's northernmost highway
There's two easy ways to reach the Arctic Circle. You could drive the incredible Dempster Highway, the only road in Canada that crosses the circle ...
10. You can celebrate in the sunshine on National Aboriginal Day
If you come North for just one day, choose the summer solstice, June 21, when endless fun keeps you active throughout the bright night. All across the Northwest Territories, National Aboriginal Day festivities fill local fairgrounds with Indigenous food, music and dance, often late into the wee hours …
12. The midnight sun gave people some kooky ideas
Up until the 1880s, Arctic navigators sought “the open polar sea,” where they reasoned that the midnight sun must keep the ocean free of ice. It took several frostbitten tragedies before their dreams of a bright polar utopia gave way to the cold hard facts.
14. And it sends temperatures through the roof
Temperatures, too, shoot up in the unrelenting light. Our all-time high temperature happened in Fort Smith on July 18, 1941, when the mercury blazed at 39.4°C (103°F) – hotter than the all-time high in Hawaii. When those sorts of conditions kick in, there's only one solution: Head out to the water to cool down.
