Nepal's climate varies with its topography and altitude. It ranges from the tropical to the arctic. The low-land Terai region with its maximum altitude to approximately 305m, which lies in the tropical southern part of the country, for instance, has a hot and humid climate that can rise above 45 Degree Celsius (113 Degree Fahrenheit) during summer. The mid-land regions are pleasant almost all the year round, although winter nights are cool. The northern mountain region, around an altitude above 3,300m has an alpine climate with considerably lower temperature in winter as can be expected.
