Mount Everest Climate

The information on Mount Everest climate could be helpful for preparing a travel to Mount Everest, the highest peak in the world. Due to the high altitude, there is snow at Mount Everest throughout the year, and the weather is awful. Perhaps the most striking feature of Everest base camp's climate is the large temperature difference between day and night. Since the weather is changeable at high altitudes, be sure to pay close attention to chnages in the weather if you want to climb the mountain.

Mount Everest Climate Features

Due to its high altitude and unique geographical environment, Mount Everest has a typical alpine climate. There is snow on the mountain all the year round, glaciers, ice slopes and serac bands can be seen anywhere. The air at the summit is thin, with only a quarter of the oxygen content of the eastern plains, and there are often strong winds. The weather at mount Everest and the surrounding mountains is changable and unpredictable. Considering the cold weather and harsh geographical conditions, many tourists have to choose the best time to challenge the highest mountain.


Due to the extremely cold climate, Mount Everest is also called the third pole of the world. According to the radio sounding data of the Tingri weather station at the foot of the Mount Everest, at an altitude of 7500 meters, the coldest month is February, the average temperature is -27.1℃, and the hottest month is August, the average temperature is -10.4℃, and the annual average temperature is -19.6℃. The lowest temperature on the top of the mountain is -30°C to -40°C (22-40°F), but cold winds can make you feel even colder. And the oxygen content of the top of the mountain is only 25% of the sea level. The strong winds blow the snow into drifts, making the mountain more deadly. Everest Base Camp is not so cold, and not that desolate, with an altitude of 5200 meters, under the snow line. The daytime temperature from spring to autumn is above zero.


Generally speaking, the rainy season is from early June to mid-september every year. The strong southeast monsoon causes the harsh climate of frequent heavy rain, fog and snow. From mid-November to mid-February of the following year, the lowest temperature can reach -50℃ and the average temperature is around -30℃ due to the strong northwest cold current. From the beginning of March to the end of May is the spring when the wind season transitions to the rainy season, and from the beginning of September to the end of October is the autumn when the rainy season changes to the wind season. During these two seasons, better weather is likely to occur, which is the best season for mountaineering.
