Owing to the varying topography and geography, Nepal’s climate also varies along with the differing topographical location. Nepal’s climate ranges from tropical to sub-tropical depending upon the altitude. The Terai region, which lies in southern part of the country, for instance, has a very hot and humid climate. The mid-land and the hilly regions are pleasant almost throughout the year, although morning and nights in winter are quite cold. The northern mountainous region, at an altitude above 3500 meters has an alpine climate with a considerably lower temperature.
Nepal has particularly has six climatic seasons, unlike the four seasons which are quite prevalent in most of the other countries. The four climate seasons most common in other countries are spring, summer, autumn and winter. Nepal, however, has six seasons which are spring (Basanta), summer (Grishma), monsoon (Barsha), autumn (Sharad), winter (Hiund) and windy (Sisir) season.
Spring is a colorful season which is highlighted by new flowers blooming in the trees and the environment is particularly green and colorful. It is followed by summer season when the weather is particularly hot and humid. The summer is followed by monsoon season when heavy showers coming from the Bay of Bengal in the East lash the nation with the rain. The monsoon rain then progressively heads towards the western region before it ceases after a couple of months giving rise to autumn season. Autumn is the best season in Nepal which is famous for the clear blue skies and pleasant temperature. Nepal’s major festivals like Dashain and Tihar fall during this season which overlaps on the months of October and November. Then comes the winter season when the temperature is low and cold. During winter, many districts in the northern mountainous regions of Nepal experience snowfall. Districts like Humla, Jumla, Dolpa and others receive heavy snowfall during winter. Nepal’s climatic variation is such that while the people living in the mountainous region may witness heavy snowfall during winter, but the people living in the southern plains might still be complaining ofhot weather. The climate of the capital city of Kathmandu is particularly moderate, with temperature hovering around 30 degree Celsius in summer and the winter is also quite pleasant with the mercury rarely going below zero degree.
