The weather of the Himalayas is clearly influenced by the monsoon but conversely the uplift of the mountain range along with that of the Tibetan Plateau has played a huge roll on the strength of the Indian Monsoon through time. The Himalayas create a boundary between the relatively warm and moist air of India and the cold dry air mass over Tibet.
For this reason, the western Himalayas in contrast to the eastern Himalayas are much drier and the monsoon starts later in the year. Let’s jump first to how the weather impacts where you can visit in the Himalayas and when is the best time to visit.
The Himalayas create a boundary between the relatively warm and moist air of India and the cold dry air mass over Tibet. The contrast between these air masses drives additional mixing. In addition, the Tibetan Plateau may act like a large heat pump due to its high surface elevation.
Interaction between the Indian Monsoon and the Himalayas The weather of the Himalayas is clearly influenced by the monsoon but conversely the uplift of the mountain range along with that of the Tibetan Plateau has played a huge roll on the strength of the Indian Monsoon through time.
If you’re planning a trip its key to understand how the weather changes throughout the year in each part of the Himalayas. The Indian monsoon is the main driver of climate and the impact of the monsoon or lack of it is of key importance for predicting the weather. A monsoon is best described as a seasonally reversing wind system.
If you want to trek in Nepal in July and August these are the best regions. Tibet: Tibet lies in the rain shadow of the Himalayas and is quite dry during the summer months.

The monsoon first reaches the Himalayas in far eastern India, Bhutan and Nepal in early June and remains over these regions for the longest time.
During the summer solar heating of the surface of the surface of the plateau drives convection which pulls in moisture from India. While during the winter intense cooling of the plateau results in an outflow of cold dense air which effectively shuts off any monsoon type action.
Arunachal Pradesh: This far eastern portion of the Himalayas receives heavy rainfall from May to September and is best visited in either April or October. Average dates of Monsoon Onset Across India.
Nepal: The general trekking seasons in Nepal run from March to May and from late September until November. The Everest and Annapurna regions are of such a high altitude that winter snows are generally light and trekking is possible from December to February (See – Weather of Everest ).
