Every winter from mid November, the Svalbard archipelago, located halfway between northern Norway and the North Pole, is covered in total darkness. On the biggest and only inhabited island, Spitsbergen, people don’t see the sun for four months. During this challenging time, residents wait longingly for March, when the sun finally rises above the horizon again. There’s a saying that Svalbard has two winters, the dark and the light winter. The dark winter, or polar night, when the sun doesn’t rise at all, is followed by a period of twilight in February and early March. This second winter is the favorite for many people on the island. The colors of the sky and landscape can change by the hour and it feels like the sun could rise above the horizon at any minute. But it doesn’t. It’s a tease that lasts for weeks.
