There are two main seasons in Nepal to visit, most of the tourists come to visit Nepal in autumn and spring season.

 

In autumn there will be large numbers of tourists because it will be very clear weather after the monsoon and very clear view of the mountains and also will be right temperature to trek;

There will be also so many tourists in nepal in spring season because on that time also will be a very clear weather to see mountains, many flowers will be blooming on this season to make nature beautiful and also will be a good temperature to trek (not too cold and not too hot).

 

So in Nepal there are mainly 4 seasons, but the trekkers who only have holidays in winter or summer, they are also recommended to come to visit Nepal and make few easy trekkings, sight seeing and tours (especially in Summer). Trekkers are also suggested to trek in Nepal in winter season but not very high, the weather will stay very clear in Nepal (like in december and January).
