However, it is also true that you can trek in any season with proper guidance and preparation.

Spring -  March / April / May 

Spring is the season when the mountains come to life, the vegetation blossoms, Rhododendrons bloom, and all the animals come out of their hidings.  Everest region is calm during this season. This season will offer you lots of breathtaking sunrises and sunset view over the Himalayas. Climate will be fair and the sky will be clear all day long which will make your trek even more.

Although because of this, it can become somewhat crowded. One can meet many other Everest climbers during this season and base camp is full of tents. The beautiful clear blue sky can be seen and the many different species of flowers are visible in the lower altitude.

During springtime, the average temperature is 17 degrees C with a maximum of 25 degrees C during sunny days and a minimum of -15 degrees C in the morning and at night for areas above 4000 meters.

Monsoon - June/ July / August 

The month of June, July and August are specially considered as the monsoon month.This season is not really recommended to travel as it rains in the lower altitudes, below 3500 meters. In areas above 4000 meters, it rains sometimes and although it is also sometimes dry, very few people travel during this season. Since the trails would be all wet, slippery and muddy due to the rain, it won’t be easy at all.

Although this is the main problem while trekking Everest Base Camp in monsoon season, there are various positive aspects which will want you to trek in this season even more. The excess rainfall can provide ample chance to see spectacular views of the waterfall and it’s also the best season to avoid the crowds.
