evidence: Winters (December to February) in the Everest region are harsh, with extreme freezing conditions. During winter, there are hurricane-force winds that will threaten to shoot off climbers from the peak. Everest is the only mountain summit that reaches the jet stream and is one of the planet’s windiest places. [...] Winter trekking to Everest base camp is still possible but climbing Mount Everest in winter is not ideal. Heavy snowfall increases the snow deposit in the mountains and makes it unstable for climbers. Besides that, freezing temperatures in the morning and night is another challenge in winters. Climbers will have to stay for a long duration in camps above an altitude of 6000m, which is quite challenging. There are cases of climbers getting instantaneous frostbite in open skin during daily chores. Winter also means that teahouses and lodges along trails get shut. This means trekking before an expedition gets difficult as well. Hence, climbing Mount Everest in winter is not ideal.
