Evidence (2024-10-06): - December 27 – Everest veteran Yasuo Kato made the second winter ascent and became the first climber to summit Everest in three different seasons. He climbed alone from the South Summit. On his descent, he and his climbing companion Toshiaki Kobayashi bivouacked below the south summit. They failed to return in bad weather.[62] [...] During the season, there were several outbreaks of COVID-19 among climbers, compounded by the Nepalese Department of Tourism neglecting to establish any rules or regulations to mitigate the risk of outbreaks at the South Base Camp.[148][147] Furthermore, the Nepalese government did not officially acknowledge any cases or outbreaks of COVID on Mount Everest,[147][149][150] and there were prohibitions enforced about what climbers were allowed to take photographs of,[147][149][151] prompting concerns about the Nepalese government attempting to cover up these problems.[147][149] [...] - ^ "Asia, Nepal, Everest Winter Ascent and Tragedy".

Evidence (2024-07-12): 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.

Evidence (2020-05-20): At some point in the spring, usually around early to mid May, the monsoon weather in the Indian Ocean pushes north over the sub-continent and this in turn pushes the high winds away to the north of Everest. This is the "weather window" that climbers use to find calmer weather at the summit. There is a similar situation caused by the impending arrival of winter that occurs in late October/early November, but this "window" is more unstable, darker and colder, so very few expeditions try to climb Everest in the post-monsoon (autumn) season. [...] Everest basecamp is very different. There are four seasons in the Khumbu, although summer is sometimes referred to as the monsoon. They are what you’d expect for the most part. Winter is very cold and it snows often. Spring is beautiful and sunny, but almost every afternoon it clouds up and sometimes a dusting of snow falls. Summer (monsoon) is warm and wet. At Everest basecamp (EBC) there are many storms and they can drop huge amounts of snow. In the autumn, the monsoon storms end and sunny warm days like spring appear until the crispy coldness creeps back into the air, the days shorten and winter rolls in again.

Evidence (2021-02-18): Rainfall is still low, but not as low as in November, and you may encounter snow anywhere along the Everest Base Camp (EBC) trail, not just at higher altitudes. You're very likely to enjoy some beautifully crisp and clear mountain views in December. [...] As temperatures are cold in December and snowfall can be a problem, it's best to avoid alternative routes in the Everest region that require crossing high passes (such as the Three Passes Trek). Treks that stay below 13,000 feet will be safer and more comfortable, but it's essential to check (or have your guide check) the weather conditions as you progress along any trek in this area. [...] December is also an ideal time to consider treating yourself to a luxury tour—there are some lovely luxury lodges in the Everest region (such as Yeti Mountain Homes and Everest Summit Lodges) on a par with comfortable boutique accommodations in Kathmandu. While this kind of trip is special at any time of year, it's even more so in winter, when you'll especially enjoy the comfort of a warm, cozy lodge at the end of a day of walking.

Evidence (2024-01-01): Climbing Mount Everest in winter is always a challenge. You will not only face the low temperature, heavy snow and wild wind, but also the loneliness and fares of the great nature. It does not only call for courage to climb Mount Everest, the highest mountain in the world, in winter, but also needs good preparations. It is not sensible to start out the climbing trip with impulse. Mountaineers should know the basic weather conditions, the best route, necessary documents, diet, accommodation, packing list and some tips for the climbing in winter. Follow the instructions in this guidance, and you will be able to enjoy the majestic Mount Everest in winter. [...] The winter of Mount Everest lasts from November to February. During these four months, the weather of this mountain is affected by the southward migration of the northern hemisphere jet stream to a great degree. This causes the heavy winds and low temperatures in Mount Everest. There is much snow during this season. This forbidden zone of life in winter has an average temperature of -45°C. The wind speed is also quite high. [...] The routes to climb Mount Everest in winter are various. Here we would like to introduce two main good routes for you to choose. One is from Nepal and the other is from Tibet.

Evidence (2024-09-13): 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.

Evidence (2019-01-31): Of the 14 mountains that rise at least 8,000 meters (26,246 feet), K2 remains the only peak unclimbed during winter. [...] "The Sherpas are much stronger than many more famous climbers," Txikon says wryly. This group joined Txikon on two consecutive, ultimately unsuccessful winter trips to Everest over the last two years, so they have a lot of experience together climbing in these extreme conditions. Having been shut down by Everest in winter twice, however, the team wanted to mix it up and try a new objective to keep the motivation high. Despite it being a far tougher mountain, perhaps they'd have better luck on K2, they reasoned. [...] K2 has long been considered too tough even to consider in winter. In fact, a winter ascent has only been attempted five times prior to this year. "It’s the worst place on Earth," Bielecki says. No team has even made it past 25,100 feet—and with the summit standing at 28,251 feet, those last 3,000 feet are going to be the toughest.

Evidence (2024-09-20): Resting majestically between the Nepali and Tibetan border, Mount Everest is the world’s tallest mountain at an elevation of 8,848.86 m (29,031.7 ft.) above sea level. Believed to be 40-50 million years old, Everest has seen attempts on its summit in increasing volumes in recent years has seen an increase in ascents in recent years. There are many things one should know when planning an expedition, climbing seasons being a significant one. The Everest climbing season is divided into pre and post-monsoon, with the best times to climb Mount Everest being spring (March-May) and fall (September-November) [...] Climbing Everest during Spring (March-May) [...] Climbing Everest during Fall (September-November)

Evidence (2021-12-16): This means that the level of oxygen on the summits of Everest and K2 in winter is as low as it would be at an altitude of around 9,100m during the climbing season. [...] The extremely thin air on the summit of Everest and K2 in winter means that any potential winter climber needs even better acclimatization than usual to deal with the greater risk of acute altitude sickness and the slower pace during the summit push. [...] To sum up, in winter, the combination of extremely low barometric pressure (which signiﬁcantly slows climbing), low air temperatures, and high wind speeds put climbers on Everest or K2 at a remarkably high risk of frostbite, hypothermia, acute mountain sickness, and metabolic deterioration.

Evidence (2024-07-08): Yes, it is possible to climb Mount Everest in winter, but it presents extreme challenges and dangers. The harsh winter weather includes freezing temperatures, heavy snowfall, and powerful winds, making the climb much more difficult and perilous than in other seasons. The thin atmosphere at such a high-altitude area becomes even less hospitable in winter, making the physical demands on climbers much greater. That’s why only a few climbers have successfully reached the summit of Everest in winter.

Evidence (2020-11-17): Winter has got to be the best time to trek to Everest Base Camp. I trekked in February and, as winter is the dry season, it generally boasts the clearest skies in the Himalayas. We were able to get amazing views of Everest and the incredible surrounding landscape as we hiked. Yes, it was cold. The EBC trek in winter is at least 10-15°C colder than the peak season. While most days were bright and clear, we did encounter blizzards, fog and ice over our 13-day trek. The evenings in the teahouses were particularly chilly, dropping to -25°C outside the lodges’ thin, wooden walls. [...] While the winter is a cold and unpredictable time to trek to EBC, it’s also one of the clearest. This means blue skies and a lot of sun. I always applied factor 50 each morning, come blizzard or shine, and got more colour in my cheeks than I did in three months in Africa.

Evidence (2021-01-15): Simulations of the human heat balance during Mount Everest summit attempts in spring and winter - PMID: 38114844 - PMCID: PMC10794380 - DOI: 10.1007/s00484-023-02594-1 Simulations of the human heat balance during Mount Everest summit attempts in spring and winter The majority of research dealing with the impacts of the Himalayan climate on human physiology focuses on low air temperature, high wind speed, and low air pressure and oxygen content, potentially leading to hypothermia and hypoxia. Only a few studies describe the influence of the weather conditions in the Himalayas on the body's ability to maintain thermal balance. The aim of the present research is to trace the heat exchange between humans and their surroundings during a typical, 6-day summit attempt of Mount Everest in the spring and winter seasons. Additionally, an emergency night outdoors without tent protection is considered. Daily variation of the heat balance components were calculated by the MENEX_HA model using meteorological data collected at automatic weather stations installed during a National Geographic expedition in 2019-2020. The data represent the hourly values of the measured meteorological parameters. The research shows that in spite of extreme environmental conditions in the sub-summit zone of Mount Everest during the spring weather window, it is possible to keep heat equilibrium of the climbers' body. This can be achieved by the use of appropriate clothing and by regulating activity level.

The images below show Rolwaling Glacier, located 20 kilometers (30 miles) south of Nanpa La. All images were acquired by the Operational Land Imager (OLI) on Landsat 8 using bands 7-5-4. [...] Melting season in the region around Mount Everest is usually concentrated during the summer monsoon (April to September). In the past year, however, abnormally warm temperatures have extended the melting period by four months. As of January 22, 2021, weather stations at Everest base camp reported maximum temperatures above freezing for eight days that month. On January 13, temperatures peaked at 7°C (45°F). "We have been basically seeing spring and summer-like conditions in the middle of winter," said Tom Matthews, a climate scientist at Loughborough University (United Kingdom) who helps manage weather stations at Mount Everest placed during the Rolex National Geographic Expedition. These melting events, said Matthews, are associated with pulses of warm air carried in by prevailing winds from the west.

Evidence (2022-05-12): Climbing Everest. Without Oxygen. In Winter. [...] In the long history of climbing on Mount Everest, there have been only a handful of summits during winter. And just one person—Ang Rita Sherpa—has climbed the world’s highest peak in the off-season without the use of supplemental oxygen. This winter, Basque climber Alex Txikon aims to become the second. [...] Polish climbers Krzysztof Wielicki and Leszek Cichy made the first winter ascent of Everest on February 17, 1980. Since then, 13 others have managed to reach the summit during that season, although eight of those occurred before December 21. Ang Rita Sherpa made his ascent without the use of bottled oxygen on December 22, 1987, just one day into the winter season, which means the bulk of the climbing and acclimatization actually took place during fall. No one has made a winter ascent since 1993.

Evidence (2024-07-22): Spring is widely regarded as the best season for a Mount Everest expedition. During this time, the weather begins to warm up, and the harsh winter conditions start to subside. The temperature at Basecamp rises over the course of the climbing season, from around -15 degrees at the beginning of March to plus degrees in May. The stable weather patterns in spring bring clear skies and reduced wind speeds, providing excellent visibility for climbers. The picturesque landscape is also adorned with blooming rhododendron forests, adding to the allure of the journey. [...] Summer on Mount Everest is challenging and dangerous due to heavy rainfall, high humidity, and the risk of avalanches and landslides. Fog and cloud cover obstruct visibility, making navigation difficult. Unstable snow conditions caused by warm temperatures at lower altitudes further endanger climbers. There are no Mount Everest expeditions in summer. [...] Autumn is another favorable season for climbing Mount Everest. The weather becomes stable after the monsoon season, with clear skies and moderate temperatures. The days are generally dry, and the wind speeds are relatively low, providing optimal climbing conditions. The average temperature at the base camp ranges from -10°C to -20°C (14°F to -4°F). The autumnal landscape offers stunning views with colorful foliage, creating a visually captivating experience for climbers.
