Some people talk about two seasonal weather periods in Nepal, with the two periods being the dry and the wet. October to May is generally the driest time to visit Nepal and the remaining four months are the wettest months. Therefore, if you are averse to rainy weather, then avoid the months of June to September as it is during this period in Nepal that the monsoon weather hits. 80% of the annual rainfall in Nepal falls during these months. The monsoon weather period in Nepal can be split into four distinct categories – pre-monsoon, summer monsoon, post-monsoon, and winter monsoon. Pre-monsoon weather refers to the significant flow of moist air arriving in Nepal, the summer monsoon refers to the period in which rainfall is at its highest, the post-monsoon refers to the decline of the monsoon weather and finally, the winter monsoon refers to a period of weather in which there are occasional periods of rainfall in the plains and lowlands of Nepal.
Depending on the reason for your trip to Nepal, then Spring and Autumn are good times for general travel. However, if the purpose of your trip is to take a Himalayan trek in the rain shadow, then Summer is a good time to go.
