The Everest Base Camp, the protection zone built for protecting the core area of Qomolangma with altitude of 5,200 meters, is one of the must-sees for any of trip to Tibet. Weather in the mountains is notoriously difficult to predict. However, it is not as gloomy and cold as you imagine, and the temperature generally features the big temperature gap, cold at night while warm during daytime. It is almost sunny and even warm in the summer time, about 12°C (22°F) colder than in Lhasa.

Winter in Tibet is snowy, icy, and windy. It's very cold to camp on EBC, tent hostels are struck, and the way to EBC is sometimes shut due to inclement weather. However the icy scenery is quite beautiful in the mostly clear, dry, frigid weather and it's less crowded.
