evidence: The combination of wind chill, frigid temperatures, and the soaring elevation makes Everest’s summit one of the most uninviting places on the planet during the winter. The wind chill-adjusted temperatures as low as -70°C (-90°F) witnessed at the summit can be compared to the chilling conditions of the world’s coldest spots, such in Siberia recorded -67.8°C (-90°F) and the -89°C (-129°F) at Vostok in Antarctica. [...] During winter, the average temperatures on Mount Everest range from approximately -37 to -34 degrees Fahrenheit. Everest Base Camp experiences slightly milder conditions, with nighttime temperatures hovering between -5 to -12 degrees Celsius, while daytime temperatures rise to around 4 degrees Celsius. [...] The changing seasons also play a role in the temperature differences on Mount Everest. In winter, the temperature on Everest drops by as much as -17 degrees Celsius compared to summer. Because of this, most climbers avoid attempting the ascent in winter and opt for spring or autumn.
