♦ Climb Mt. Everest in Spring
Dust from the plains of India during the spring routinely provides less than ideal conditions for clear mountain views. April and early May is a good time to see the hedgerows and trees bursting into bloom, with Rhododendrons, in particular, adding a spectacular splash of color to the landscape
♦ Climb Mt. Everest in Summer
The views are much better after the summer monsoons have cleared the atmosphere of dust, but the days are shorter and cooler. But in summer, pay attention to the threatening monsoon season.
♦ Climb Mt. Everest in Autumn
There is a good time in Autumn to climb Mt. Everest after the monsoon season fading out.
♦ Climb Mt. Everest in Winter
The winters are very cold and snow may make it difficult to travel higher than Tengboche, and also lodges may be closed above this altitude. Summers, on the other hand, are wet, and the spectacular peaks are often lost in the clouds.
