December, January, and February are winter months in Nepal and therefore are the coldest months of the year. The mountain region, around an altitude of 3353m, has an alpine climate with considerably low temperatures in winter as expected. On a positive note, the Everest Base Camp trek is much quieter during this time. The lakes are frozen and snow makes the surrounding landscape remarkably picturesque.
During this time of the year, all of the mountain ranges become covered with snow and thus provide beautiful vistas. You will feel like you’ve stepped into a winter wonderland. In the winter it doesn't rain, so the temperature is bearable in the low land. However, during this time of year, there will be heavy snowfall in the high-altitude regions.
Temperatures are typically much colder during this time of the year, though the mountain views make the trip worth it. This is an excellent time to visit Everest Base Camp if you want a challenging, secluded adventure. Other Everest region treks also become less crowded due to people's worry that they can not bear the extremely low temperature, including Gokyo Valley Trekking, and Everest Panorama Trekking.
Generally, Everest Base Camp weather during December, January, and February is very cold i.e. cold at night and in the early mornings. Generally, high-altitude treks like Everest Base Camp Cho La Pass Trek are not recommended during this time of the year. However, both daytime and nighttime temperatures are bearable, and it’s possible to hike EBC during this time. But keep in mind, that you need to be well prepared with proper gear and equipment. Even when winter is at its most severe, it is compensated by the bright sun and brilliant views. The lower areas, averaging around 2000 meters above sea level, have a milder climate and you won’t have to worry too much about inclement weather.
The wind chill factor will make you feel much colder than the temperature suggests. Nepal's winter weather can range from cold and frosty to warm and sunny. The average temperature during these months is 17 °C. Sunny days can bring temperatures reaching about 25 °C whereas early mornings and nights drop to -15 °C in areas above 4000 meters. These temperatures are considered extreme by some, but the mountain views are often at their best and reward those who can bear the cold. In addition, you also don't have to compete for space along the trails or in the tea houses. You’ll have complete peace on the trail.
