By end of September through to December the weather is usually stable with mild to warm days, cold nights. February, March, April, May, October, November, December are favorable to do Everest base camp trek.

The Mount Everest has an extreme climate. The summit temperature never rises above freezing or 32° F (0° C). Its summit temperatures in January average -33° F (-36° C) and can drop to -76° F (-60° C), and its average summit temperature in July is -2° F (-19° C). Weather in the mountains is notoriously difficult to predict. At night it is generally cooler, while the days are generally warm. Winter (January and February) will be bit colder but the days can be quite beautiful and warm if the sun is out. There will be bit of snow during the month of January, February and December. It is also important to make sure that you can stay warm and dry in just about any conditions. It is really unpredictable. The temperature could be as high as 20 ° C and as low as -15 ° C.

There are two Everest base camps on opposite sides of Mount Everest, namely South Everest Base Camp in Nepal and North Everest Base Camp in Tibet, southwest China. The latter one is located at an altitude of 5,545 metres (18,192 ft) and is used when climbing via the northeast ridge. The North Base Camp has vehicle access (at least in the summer months) through a 100km road branching to the South from the Friendship Highway near Shegar. Climbers typically rest at base camp for several days for acclimatization; to reduce the risks and severity of altitude sickness.

Since 2010, a visit to the North Base Camp in Tibet requires a permit from the Chinese government, on top of the Tibet entry permit required to visit Tibet itself. At this time such permits must be arranged via Tibet travel agencies as part of a package tour that include hiring a vehicle, driver and guide. The "tourists Base Camp" is located about half-way between Rongbuk Monastery and the actual climbers Base Camp at the foot of Rongbuk glacier.
